Yummy Plastics

“From Waste to Food: A Generator of Future Food” by Ting Lu and Stephen Techtmann, won the Merck 1 million prize.  It concerns an efficient, economical and versatile technology that converts wastes such as end-of-life plastics into edible foods. These foods contain all the required nutrition, are non-toxic, provide health benefits, and additionally allow for personalization needs. This technology promises to transform waste streams into nutritious food supplements, thus solving the two problems of increasing food scarcity and plastic waste simultaneously.

The core of the proposed technology is to harness synthetic microbial consortia – a combination of natural and rationally engineered microorganisms – in order to efficiently convert waste into food. The project will comprise four research goals: conversion from polyethylene terephthalate (PET) to protein powder (goal 1), augmentation of biosafety for food and for the environment (goal 2), introduction of nutritional and health-promoting contents (goal 3), and expansion of the technology to include additional plastics or other types of waste (goal 4). The proposed work will establish a transformative basis for food generation.

Green Con Artists and their Moneyed Followers

Green investing has grown so fast that there is a flood of money chasing a limited number of viable companies that produce renewable energy, electric cars and the like. Some money managers are stretching the definition of green in how they deploy investors’ funds. Now billions of dollars earmarked for sustainable investment are going to companies with questionable environmental credentials and, in some cases, huge business risks. They include a Chinese incinerator company, an animal-waste processor that recently settled a state lawsuit over its emissions and a self-driving-truck technology company.

One way to stretch the definition is to fund companies that supply products for the green economy, even if they harm the environment to do so. In 2020 an investment company professing a “strong commitment to sustainability” merged with the operator of an open-pit rare-earth mine in California at a $1.5 billion valuation. Although the mine has a history of environmental problems and has to bury low-level radioactive uranium waste, the company says it qualifies as green because rare earths are important for electric cars and because it doesn’t do as much harm as overseas rivals operating under looser regulations…

When it comes to green companies, “there just isn’t enough” to absorb investor demand…In response, MSCI has looked at other ways to rank companies for environmentally minded investors, for example ranking “the greenest within a dirty industry”….

Of all the industries seeking green money, deep-sea mining may be facing the harshest environmental headwinds. Biologists, oceanographers and the famous environmentalist David Attenborough have been calling for a yearslong halt of all deep-sea mining projects. A World Bank report warned of the risk of “irreversible damage to the environment and harm to the public” from seabed mining and urged caution. More than 300 deep-sea scientists released a statement today calling for a ban on all seabed mining until at least 2030. In late March 2021, Google, battery maker Samsung SDI Co., BMW AG and heavy truck maker Volvo Group announced that they wouldn’t buy metals from deep-sea mining.

[However the The Metals Company (TMC) claims that deep seabed mining is green].

Junk: the Engine of Green Growth

“Plastic waste is not just a global crisis that threatens economic recovery, climate, and nature. It is also an investment opportunity that can flip it from a scourge into an engine for economic development,” said Rob Kaplan, who founded Circulate Capital in 2017. Initially the firm sought to back companies in India and Southeast Asia, such as recycling or waste-sorting companies, that help reduce the amount of plastic waste that winds up in the ocean.

In 2019 it raised a $106 million debt and project finance fund, Circulate Capital Ocean Fund, backed by a handful of large multinational corporations that include Coca-Cola, Danone,  Procter & Gamble,  and Unilever…Circulate is one of a small but growing number of firms investing in companies that contribute to what they call the circular economy, a business model that seeks to eliminate waste that organizations produce, continuously reuse products and materials and regenerate natural systems.

An estimated 30 private-market funds, including private-equity, venture and debt strategies focused on the circular economy in the first half of 2020, up from just three in 2016….A number of large multinational corporations are funding these firms’ efforts as part of a broader push to reduce both the overall waste their own companies produce and the amount of virgin materials they use.

Unilever, which has backed funds managed by Circulate and New York-based Closed Loop Partners, aims to cut in half the amount of virgin plastic it uses by 2025 and plans to collect and process more plastic packaging than it sells. Coca-Cola, also a backer of Circulate’s Ocean fund, aims to make all of its global packaging recyclable by 2025 and to use at least 50% of recycled packaging material by 2030, among other goals.

Save Time and Money but Destroy Soil and Oceans

The images of swaths of garbage floating on the oceans’ surface have become a rallying call to address plastic pollution, but there is more to this challenge than meets the eye. While plastics and microplastics – items smaller than 5 mm – accumulate and impact marine environments, much of the problem is rooted in land contamination. Land-based plastic pollution, which often feeds into the oceans, is estimated to be at least four times higher than what is in the oceans, according to a study published in Global Change Biology. 

“Soil is the main source of microplastics reaching oceans through soil erosion and surface runoff,”  Plastics settle in soil through disposal in landfills, as well as through the use of plastic-sheets in agriculture or application of microplastic contaminated compost. “Direct disposal of plastics to ocean is relatively less pronounced compared to the transfer of microplastics from land. Microplastics, lighter than soil particles, such as sand, silt and clay, are easily lost to waterways,”…

“We contribute to plastic pollution through indiscriminate disposal of plastics in landfills and use of microbeads in cosmetics and microfibers in textiles. There are efforts to produce biodegradable plastics, which may provide some solution to plastic pollution, but bioplastic may not be the silver bullet to manage plastic pollution.” Commonly used biodegradable bioplastics “retain their mechanical integrity under natural conditions, potentially causing physical harm if they are ingested by marine or terrestrial animals.” “The fate of biodegradable bioplastics in natural and engineered environments could be potentially problematic. Methane is a product of biodegradation in anaerobic environments in landfills.” These bioplastics, furthermore, require high temperatures, controlled aeration and humidity to degrade completely.

Due to their small size, microplastics, especially nanoplastics resulting from the degradation of microplastic, can enter organisms’ internal organs, where they could potentially transfer contaminants attached to them. These can include persistent organic pollutants, like polychlorinated biphenyls (PCBs), as well as trace metals like mercury and lead. The plastics and pollutants that accumulate on or in them enter the food chain and can eventually be transferred to humans, causing growing food safety concerns.

The Joint FAO/IAEA Centre’s laboratories are equipped to research the presence of microplastics in food. “Techniques such as energy dispersive X-ray spectroscopy and infrared and Raman spectroscopy can be applied to screen for plastics in foods, enabling risk assessment and management,” said Andrew Cannavan, Head of the Joint Centre’s Food and Environmental Protection Section.

The Most Radioactive Sea on Earth and How to Save it

No other places in the world’s oceans have more radioactive and nuclear waste than the Kara Sea. The reactors from the submarines K-11, K-19, and K-140, plus the entire submarine K-27 and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted from the seafloor and secured. While mentality in Soviet times was «out of sight, out of mind», the Kara Sea seemed logical. Ice-covered most of the year, and no commercial activities. That is changing now with rapidly retreating sea ice, drilling for oil-, and gas and increased shipping.

The submarine reactors dumped in shallow bays east of the closed-off military archipelago of Novaya Zemlya… had experienced accidents and posed a radiation threat at the navy yards where people were working.  Dumping the reactors in shallow waters, someplace at only 50 meters, meant they could be lifted one day when technology allowed.

A worst-case scenario would be a failed lifting attempt, causing criticality in the uranium fuel, again triggering an explosion with following radiation contamination of Arctic waters.  

A Russian-Norwegian expedition to the K-27 submarine in Stepovogo bay in 2012 took samples for studying possible radioactive leakages. Now, the Bellona group, an environmental NGOs, calls  an expedition in 2021  to thoroughly study the strength of the hull and look for technical options on how to lift the heavy submarine and reactor compartments. A previous study report made for Rosatom and the European Commission roughly estimated the costs of lifting all six objects, bringing them safely to a yard for decommissioning, and securing the reactors for long-term storage.

The estimated price-tag for all six is €278 million, of which the K-159 in the Barents Sea is the most expensive with a cost of €57.5 million. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

The Wild West Mentality of Companies Running the U.S. Oil and Gas Infrastructure — and Who Pays for It

The ransomware attack on Colonial Pipeline Co. in May 2021 has hit an industry that largely lacks federal cybersecurity oversight, leading to uneven digital defenses against such hacks.

The temporary shutdown of Colonial’s pipeline, the largest conduit for gasoline and diesel to the East Coast, follows warnings by U.S. officials in recent months of the danger of cyberattacks against privately held infrastructure. It also highlights the need for additional protections to help shield the oil-and-gas companies that power much of the country’s economic activity, cyber experts and lawmakers say. “The pipeline sector is a bit of the Wild West,” said John Cusimano, vice president of cybersecurity at aeSolutions, a consulting firm that works with energy companies and other industrial firms on cybersecurity. Mr. Cusimano called for rules similar to the U.S. Coast Guard’s 2020 regulations for the maritime sector that required companies operating ports and terminals to put together cybersecurity assessments and plans for incidents.

 More than two-thirds of executives at companies that transport or store oil and gas said their organizations are ready to respond to a breach, according to a 2020 survey by the law firm Jones Walker LLP. But many don’t take basic precautions such as encrypting data or conducting dry runs of attacks, said Andy Lee, who chairs the firm’s privacy and security team. “The overconfidence issue is a serious phenomenon,” Mr. Lee said.

Electric utilities are governed by rules enforced by the North American Electric Reliability Corp., a nonprofit that reviews companies’ security measures and has the power to impose million-dollar fines if they don’t meet standards. There is no such regulatory body enforcing standards for oil-and-gas companies, said Tobias Whitney, vice president of energy security solutions at Fortress Information Security. “There aren’t any million-dollar-a-day potential fines associated with oil-and-gas infrastructure at this point,” he said. “There’s no annual audit.”

How Air Pollution Infiltrates the Seas

A global effort to curb pollution from the heavy fuel oil burned by most big ships appears to be encouraging water pollution instead. A 2020 regulation aimed at cutting sulfur emissions from ship exhaust is prompting many owners to install scrubbing systems that capture pollutants in water and then dump some or all of the waste into the sea.

Some 4 300 scrubber-equipped ships are already releasing at least 10 gigatons of such wastewater each year, often in ports and sometimes near sensitive coral reefs…. The shipping industry says pollutants in the waste don’t exceed national and international limits, and that there’s no evidence of harm. But some researchers fear scrubber water, which includes toxic metals such as copper and carcinogenic compounds called polycyclic aromatic hydrocarbons, poses a rapidly growing threat, and they want to see such systems outlawed.

The emerging debate is the result of a 2020 regulation put into place by the International Maritime Organization (IMO), an arm of the United Nations that works with 174 member states to develop common rules for international shipping. By banning the use of sulfur-heavy fuel oil, the rule intended to reduce pollutants that contribute to acid rain and smog. IMO estimated the rule would slash sulfur emissions by 77% and prevent tens of thousands of premature deaths from air pollution in ports and coastal communities.

But cleaner fuel can cost up to 50% more than the sulfur-rich kind, and the rule allows ship owners to continue to burn the cheaper fuel if they install scrubbers. In 2015, fewer than 250 ships had scrubbers (often to comply with local regulations); last year, that number grew to more than 4300, according to industry figures.

A scrubber system sends exhaust through a meters-tall metal cylinder, where it is sprayed with seawater or freshwater, depending on the type, at rates comparable to gushing fire hydrants, to capture pollutants. In the most popular systems, called open loop scrubbers, seawater is discharged to the ocean after little or no treatment. Other systems retain sludge for disposal on land and release much smaller (but more concentrated) amounts while at sea….Researchers are particularly worried about discharges in areas that IMO has designated as ecologically sensitive. The Great Barrier Reef, for example, receives about 32 million tons of scrubber effluent per year because it’s near a major shipping route for coal. Ships also release scrubber water around the Galápagos Islands….

Ports see substantial discharges, too. Cruise ships dominate those releases, contributing some 96% of discharges in seven of the 10 most discharge-rich ports. Cruise ships typically need to burn fuel in port to continue to operate their casinos, heated pools, air conditioning, and other amenities. Most ports have shallow water, so pollutants are less diluted and can accumulate more rapidly….

Researchers, who are participating in a €7.5 million European effort to study shipping pollution called EMERGE, would like to study how scrubber water affects fish larvae.

But shippers have become hesitant to share samples and data with scientists. “We’re reluctant to give it to organizations which we know have already an established agenda,” says Mike Kaczmarek, chairman of the Clean Shipping Alliance 2020

The ultimate solution is to require ships to use the cleanest fuel, called marine gas oil. In the meantime, 16 countries as well as some localities have banned the most common scrubbers.

A Gun to their Head: the Exclusive Vaccine Club

International tensions over access to Covid-19 vaccines have intensified as supply hiccups disrupt mass rollouts of shots. But trade experts warn that restrictions on vaccine exports risk making a bad situation worse. That’s because the world’s major vaccine producers rely on each other for the essential ingredients to manufacture vaccines through a web of cross-border supply chains in complex chemicals, fatty acids and glass vials. If governments restrict vaccine exports, they risk retaliation from other members of this exclusive club of vaccine makers, who could withhold vital supplies, squeezing production just when it is needed most.

These supply chains stretch across the world, drawing in producers of basic chemicals that provide critical ingredients as well as the pharmaceutical powerhouses that make the vaccines. The  U.S. , the  European Union  and  China  are among a handful of territories that produce vaccine ingredients and final vaccines for the entire world. More than half of global vaccines and of key vaccine ingredients come from the  U.S.  and  EU . These 12 countries and the EU make up the “Vaccine Club”—producers that make both the key ingredients as well as final vaccines

The members of the vaccine club, though, source on average 88.3% of the imported ingredients used in vaccine production from other club members, according to economists led by Simon Evenett, professor of international trade and economic development at the University of St. Gallen in Switzerland, who have mapped trade flows between the world’s major vaccine producers. Limiting vaccine exports to another major producer would therefore risk retaliatory action that could undermine production, threatening the mass vaccination drives that are the key to ending the pandemic, Prof. Evenett said. “Everyone has a gun to each other’s heads,” he said.

Begging for a Vaccine: the other COVID crisis

On April 16, 2021  Adar Poonawalla, head of the world’s biggest vaccine-maker, the Serum Institute of India (SII), begged President Joe Biden, in a tweet, to ‘lift the embargo of raw material exports out of the us.’… because it would affect the manufacturing of vaccines: AstraZeneca’s, of which SII makes 100m doses a month, and Novavax’s, of which it expects to make 60m-70m doses a month.

That was shortly after the Biden administration announced, on February 5, 2021, plans to use the Defense Production Act (DPA)—a law dating from the 1950s that grants the president broad industrial-mobilization powers—to bolster US vaccine-making. This legislation…has helped American pharmaceutical companies to secure a variety of special materials and equipment, including plastic tubing, raw goods, filters and even paper, that are needed for vaccine production. But firms which export such products point out that the DPA  hinders their ability to sell them abroad. They must seek permission before exporting these goods. That requires time and paperwork. And if the government decides it needs the goods in question to remain in the country, the firms concerned may be barred from exporting them at all… 

To be used in vaccine manufacturing, products have to be approved by regulators. So finding substitutes quickly can be impossible. SII is not alone in its concern. On March 24, 2021  Micheal Martin, Ireland’s prime minister, warned that export bans (and not just from America) would harm global vaccine production. He noted that the Pfizer vaccine involves 280 components from 86 suppliers in 19 countries. Indeed, American export controls particularly harm European vaccine companies, which need special bags from America in which to make their products. At a vaccine supply-chain meeting in March, one such firm complained of 66-week delivery times for the supply of these bags.

The Plastics Revolution: A Century Later

Businesses pay a fee to Tontoton,  a company established in 2019,  for every ton of plastic that they generate. Tontoton then uses the money to employ scavengers, who retrieve an equal weight of plastic garbage in Vietnam — the world’s No. 4 source of ocean debris…Tontoton said it has the only such program in Vietnam, while Plastic Bank runs a similar one in Indonesia and the Philippines, and the Plastic Collective covers Malaysia, Thailand, and Cambodia…Tontoton targets the worst ocean-bound rubbish, called orphan plastic because it cannot be recycled. Trash pickers find the single-use plastic along the cyan waters hugging Vietnam’s Phu Quoc and Hon Son islands. Their goal is to collect 5,000 tons a year and send it to INSEE, part of Siam City Cement, to be burned for energy….

These cleanup programs have sprung up globally as doubts emerge about recycling, which used to seem like a win-win idea because consumers could keep consuming and the environment could stay pristine. But instead, for decades, the public believed its plastic was being recycled, only to find that 91% of it was not, according to a study in the peer-reviewed journal Science Advances, assessing all plastic from 1950-2015.

Vietnam is a focus of cleanup campaigns because it’s among the top five countries sending litter to sea, along with China, Indonesia, the Philippines, and Thailand…These Asian countries earned this marker because they import so much waste for processing from the rest of the world.

Tontoton says clients sign a letter committing to multiple strategies beyond offsets, including plastic substitutes and reduction. The company helps them offset or “neutralize” plastic already used, but this isn’t a “getaway car” to escape broader responsibility. “Plastic neutralization cannot solve the problem by itself.”

Better than Gods: Can We Master the Climate?

Given the urgency of the risks posed by climate change, the U.S. should pursue a research program for solar geoengineering — in coordination with other nations, subject to governance, and alongside a robust portfolio of climate mitigation and adaptation policies, says a 2021 report from the National Academies of Sciences, Engineering, and Medicine. The report emphasizes that solar geoengineering is not a substitute for reducing greenhouse gas emissions.
 
Solar geoengineering refers to strategies designed to cool Earth either by adding small reflective particles to the upper atmosphere, by increasing reflective cloud cover in the lower atmosphere, or by thinning high-altitude clouds that can absorb heat. While such strategies have the potential to reduce global temperatures and thereby ameliorate some of the risks posed by climate change, they could also introduce an array of unknown or negative consequences

Scientific understanding of many aspects of solar geoengineering technologies remains limited, including how they could affect weather extremes, agriculture, natural ecosystems, or human health. There currently is no coordinated national effort for solar geoengineering research. The report recommends a comprehensive plan for governing solar geoengineering research, designed to ensure it moves forward in a socially responsible manner. Researchers should follow a code of conduct, for example, and research should be catalogued in a public registry, be subject to regular program assessment and review, and allow for public engagement.

Deliberate outdoor experiments that involve releasing substances into the atmosphere should be considered only when they can provide critical observations that cannot be provided by laboratory study, modeling, or experiments of opportunity — such as volcanic eruptions. Outdoor experiments should be subject to appropriate governance including permitting and impact assessments, says the report…The report says the U.S. Global Change Research Program (USGCRP) should lead the effort to establish and coordinate a solar geoengineering research program across federal agencies and scientific disciplines, with funding in the range of $100 million-$200 million over the first five years. USGCRP would enable oversight and governance of research activities, including ensuring peer review, coordinating budget proposals and requests, periodically assessing progress, and defining program goals. Funding should be set aside specifically for implementation of governance and public engagement efforts.

Nuking Tahiti: the Moruroa Files

From 1966 to 1974, France blew up 41 nuclear weapons in above-ground tests in French Polynesia, the collection of 118 islands and atolls that is part of France. The French government has long contended that the testing was done safely. But a new analysis of hundreds of documents declassified in 2013 suggests the tests exposed 90% of the 125,000 people living in French Polynesia to radioactive fallout—roughly 10

The findings come from a 2-year collaboration, dubbed the Moruroa Files, between Disclose, a French nonprofit that supports investigative journalism; Interprt, a collective of researchers, architects, and spatial designers affiliated with the Norwegian University of Science and Technology who focus on environmental issues; and the Science & Global Security program at Princeton. The findings were presented on 9 March on the project’s website, in a book, and in a technical paper posted to the arXiv preprint server.

The abandoned testing facility at the Moruroa Atoll. The atoll is at the risk of collapsing due to nuclear blasts

Declassified documents suggest actual exposures were between two and 20 times higher than France’s Atomic Energy Commission (CEA) estimates… Reasons for the discrepancies vary from test to test, he says. For example, CEA acknowledged that the first test, dubbed Aldébaran, exposed residents of the Gambier Islands to relatively high levels of fallout. But actual exposures were likely higher still… Although CEA noted that contaminated rainwater fell on the island, he says, it failed to consider that many residents likely drank the contaminated water, collected in household cisterns, for days.

Most important, the documents suggest a single test in 1974, called Centaure, exposed the entire population of Tahiti—87,500 people at the time—to fallout. French authorities set off a relatively tiny atom bomb with an explosive yield equal to 4 kilotons of TNT, and weather forecasts predicted that winds should carry fallout to the north. Instead, the wind blew to the west, carrying the plume directly over Tahiti. A new simulation based on data in the documents shows how the plume of radiation wafted over the island. CEA estimated that people on the island received a dose of about 0.6 mSv.  However, Phillipe and colleagues argue that CEA underestimated the total amount of radiation that accumulated on the ground over several days, didn’t account for radiation lingering in vegetables consumed later…

The new analysis moves the vast majority of French Polynesians past the exposure threshold to qualify for compensation. Philippe and Schoenberger would like to see France do away with the exposure standard and compensate anyone who lived through the tests and developed a qualifying cancer. “Our hope is to demonstrate that this kind of threshold can be prejudicial to claimants just because of the difficulties of proving exposure,” Schoenberger says.

Philippe estimates that, assuming a cancer rate of 0.2% per year, roughly 10,000 cancer patients or their families would qualify retroactively and that compensating them would cost about €700 million. Future cancers would cost about €24 million per year, he estimates. However, Hughes says it remains to be seen whether the French government will even acknowledge the analysis. “My fear is that they will simply ignore it,” Hughes says.

The declassified documents also show the French government routinely failed to warn Polynesians about the radiation risks, Philippe says. In the Centaure test, authorities could have warned Tahitians about the approaching fallout 2 days in advance, but did not. Ironically, Philippe notes, the United States, the Soviet Union, and other countries were monitoring the tests remotely. “Everybody knew what was going on,” he says, “except the Polynesians.”

Wild West: Mercury Pollution in the Amazon Rainforest

Munduruku Indigenous people in the Tapajós basin – an epicenter of illegal gold mining in the Amazon rainforest – in southwestern Pará state have reported increasing encroachments upon their lands by armed “wildcat” miners known as “garimpeiros” since March 14, 2021. The Federal Prosecutor’s Office has warned of a potential for violence between local residents and the miners and urged the deployment of the federal police and other authorities to remove the trespassers. But the government has yet to act. The tension has escalated in recent weeks after a group of miners brought equipment to the area.

Illegal mining causes significant deforestation in the Brazilian Amazon and has been linked to dangerous levels of mercury poisoning, from mercury widely used to process the gold, in several Munduruku communities along the Tapajós basin. Indigenous people also fear that miners could spread the Covid-19 virus in their communities.

In a public statement on March 16, 2021 the Federal Prosecutor’s Office reported that a helicopter appeared to have escorted the miners and their equipment, suggesting the invasion is “an orchestrated action” by an organized crime group. The office also reported that the miners may be coordinating the invasion with a “small group” of Indigenous people who support the mining. Members of Munduruku communities who oppose the mining and have reported the invasions to the authorities say they have faced threats and intimidation. On March 19, 2021 armed men reportedly prevented a group of Munduruku Indigenous people from disembarking from their boats in an area within their territory. On March 25, 2021 in the Jacareacanga municipality, miners and their supporters forced their way into a building that houses the Wakoborun Women’s Association and other community organizations that have opposed the mining. The attackers destroyed furniture and equipment and set fire to documents, Indigenous leaders reported…

President Bolsonaro has signaled his aversion to protecting Indigenous lands. As a candidate, he vowed not to designate “one more centimeter” of land as Indigenous territory. His administration has halted the demarcation of Indigenous territories – there are 237 pending requests – leaving Indigenous communities even more vulnerable to encroachments, deforestation, and violence. The Munduruku territory is already demarcated. In 2020, Bolsonaro introduced a draft bill in Congress to allow mining and other commercial activities in Indigenous territories. The bill is pending in Congress and is listed as one of Bolsonaro’s priorities.

It’s Easy: How to Make a Radioactive Dirty Bomb

A truck carrying highly radioactive materials has been stolen by armed criminals in central Mexico the Independent reported on April 12, 2012. The Mexican government is now warning that anybody who comes in close contact with its deadly payload could be risking their lives. The individuals got away with an industrial inspection equipment truck during an armed heist on April 11, 2021 in the town of Teoloyucan. Included in the bounty is a QSA Delta 800 gamma ray projector that holds radioactive iridium-192, selenium-75 and ytterbium-169 isotopes — a highly unusual bounty for any hijacker.

It’s still unclear why they targeted the truck in question, but during a previous robbery involving radioactive waste, Mexican authorities feared the ingredients may be used to build a dirty bomb. Contact with the contents of the truck, authorities emphasized, can be fatal. “At 10am today, there was a robbery of radiographic equipment reported,” reads a warning issued by the National Commission for Nuclear Security and Safeguarding, as quoted by the Independent. “If the radioactive material is extracted from the container, is moved, or makes direct contact with any persons handling it, permanent injury can occur in minutes.” “In case of making direct contact with the source over the course of hours or days, the effects can prove fatal,” the warning reads. Even just being 30 meters away could cause radiation poisoning, according to the Commission.

Members of the Commission for National Civil Protection (CNPC) have been dispatched across the central region of Mexico. Authorities have not ruled out the possibility that the truck may now be in Mexico City….This is not the first time radioactive material has been stolen in Mexico.

Facing the Unprecedented: Nuclear Waste Burial in China

China is building a massive underground laboratory to research disposal technologies for high-level radioactive waste, the most dangerous byproduct of nuclear technology and applications. This is meant to pave the way for a repository that can handle the disposal of at least a century’s worth of such materials for tens of thousands of years, the lab’s chief designer told China Daily in an exclusive interview.

The lab will be situated in granite up to 560 meters below ground in the Beishan region of Gansu province, said Wang Ju, vice-president of the Beijing Research Institute of Uranium Geology. The underground lab was listed as one of China’s major scientific construction projects in the 13th Five-Year Plan (2016-20).

Its surface facilities will cover 247 hectares, with 2.39 hectares of gross floor space. The underground complex will have a total structural volume of 514,200 square cubic meters, along with 13.4 kilometers of tunnels, he added. The lab is estimated to cost over 2.72 billion yuan ($422 million) and take seven years to build. It is designed to operate for 50 years, and if its research proves successful and the site is suitable, a long-term underground repository for high-level waste will be built near the lab by 2050

According to the 14th Five-Year Plan (2021-25), China seeks to cut carbon emissions by optimizing its energy consumption structure and raising its proportion of nonfossil energy. This includes building a new generation of coastal nuclear plants,… small-scale reactors and offshore floating reactors.. As of 2020, China had 49 nuclear reactors in operation, making it the world’s third-largest nuclear energy producer, behind the United States and France. There are 16 nuclear reactors in construction in China, the most in the world, according to the World Nuclear Association.

The Fukushima Nuclear Meltdown: Ten Years — and Counting

A resolution to the crisis at the Fukushima Daiichi nuclear power plant remains a distant goal a decade after three of its reactors melted down. The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin because of high radiation inside the reactor buildings, putting the targeted decommissioning of the plant by 2051 into doubt.

More than 80% of the Japanese public doesn’t feel significant progress is being made and is concerned about further accidents because of recent events. On Feb. 13, 2021 a large earthquake centered near Fukushima, an aftershock of the one 10 years ago, caused water to slosh out of a tank containing spent fuel rods, which must be kept submerged to avoid overheating. A week later, a fish caught off the coast of Fukushima was found to contain 10 times the allowed level of radioactive cesium…This incident shows how risks from the plant continue to weigh on those who live and work nearby. 

“We are still struggling with harmful rumors from the nuclear plant accident,” said Tadaaki Sawada, a spokesman for the federation of Fukushima fishery cooperatives. “How many more years will it continue?”…By several measures, the worst nuclear disaster since the Chernobyl accident in 1986 has been contained. Only around 2% of Fukushima prefecture, or state, is still a no-go area, down from 12% immediately after the disaster. An extensive decontamination process removed topsoil from areas around the plant. Still, thousands of people remain forced out of towns closest to the plant.

In 2020, plant operator Tokyo Electric Power Co., known as Tepco, and the government were close to a decision to start releasing into the sea over a million cubic meters of water from the plant, but plans were suspended amid opposition from local fishermen and concerns raised by neighboring countries. Contaminated rain and groundwater is stored in large tanks that dominate one side of the plant site. Once treated to remove most radioactive elements, the water still contains tritium, a form of hydrogen that emits a weak form of radiation. Tritium is regularly released into the sea and air from nuclear plants around the world after dilution.

Inspectors from the International Atomic Energy Agency visited the Fukushima plant in 2020 and said disposal of the treated water into the sea would be in line with international practice. “A decision on the disposition path should be taken urgently” to keep the overall decommissioning on track, the IAEA said.

The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin…Tepco has yet to get a clear picture of the location of molten fuel in the reactors because the levels of radiation are damaging even to robots…Gov. Uchibori said that gaining an accurate grasp of the molten-fuel situation was critical to making headway. “If you look at the entire process, right now we are still around the starting point of decommissioning,” he said.

The Toxic Shadow of Abandoned Oil Infrastructure

Wearing blue hard hats, white hazmat suits and respirator masks, workers carted away bags of debris on a recent morning from a sprawling and now-defunct oil refinery once operated by Philadelphia Energy Solutions (PES). Other laborers ripped asbestos from the guts of an old boiler house, part of a massive demolition and redevelopment of the plant, which closed in 2019 after a series of explosions at the facility.

Plans call for the nearly 1,400-acre site to be transformed into a new commercial hub with warehousing and offices. All it will take is a decade, hundreds of millions of dollars, and confronting 150 years’ worth of industrial pollution, including buried rail cars and a poisonous stew of waste fuels poured onto the ground. A U.S. refinery cleanup of this size and scope has no known precedent, remediation experts said. It’s a glimpse of what lies ahead if the United States hopes to wean itself off fossil fuels and clean up the toxic legacy of oil, gas and coal.

President Joe Biden wants to bring the United States to net-zero greenhouse gas emissions by 2050 to fight climate change through a shift to clean-energy technologies, while reducing pollution in low-income and minority neighborhoods near industrial facilities. It’s a transition fraught with challenges. Among the biggest is what to do with the detritus left behind. The old PES plant is just one of approximately 135 oil refineries nationwide, to say nothing of the country’s countless gas stations, pipelines, storage hubs, drill pads and other graying energy infrastructure.

In Philadelphia, a private-sector company is taking the lead. Hilco Redevelopment Partners, a real estate firm that specializes in renovating old industrial properties, bought the PES refinery out of bankruptcy for $225.5 million in June…The full extent of the pollution won’t be understood for years. Also uncertain is the ability of the refinery’s previous owners to pay their share of the cleanup. The facility has had multiple owners over its lifetime and responsibility has been divided between them through business agreements and legal settlements.
Oil refining at the Philadelphia site began in 1870, 100 years before the creation of the U.S. Environmental Protection Agency (EPA). Gasoline, once a worthless byproduct of heating oil, was routinely dumped by the refinery into the soil, according to historians and researchers. Leaks and accidents spewed more toxins. The June 2019 blasts alone released 676,000 pounds of hydrocarbons, PES said at the time. The Philadelphia site is not unique. About half of America’s 450,000 polluted former industrial and commercial sites are contaminated with petroleum, according to the EPA.

Cleanup in Philadelphia will be painstaking. After asbestos abatement comes the demolition and removal of 3,000 tanks and vessels, along with more than 100 buildings and other infrastructure, the company said. Then comes the ground itself. Hilco’s Perez said dirt quality varies widely on the site and will have to be handled differently depending on contamination levels. Clearing toxins like lead must be done with chemical rinses or other technologies…The site also has polluted groundwater and giant benzene pools lurking underneath, according to environmental reports Sunoco filed over the years with the federal and state governments.

How the Global Trade in Plastics Spills Over the Oceans

Low-value or “residual” plastics – those left over after more valuable plastic is recovered for recycling – are most likely to end up as pollution. So how does this happen? In Southeast Asia, often only registered recyclers are allowed to import plastic waste. But due to high volumes, registered recyclers typically on-sell plastic bales to informal processors…When plastic types were considered low value, informal processors frequently dumped them at uncontrolled landfills or into waterways.

Plastics stockpiled outdoors can be blown into the environment, including the ocean. Burning the plastic releases toxic smoke, causing harm to human health and the environment. When informal processing facilities wash plastics, small pieces end up in wastewater, which is discharged directly into waterways, and ultimately, the ocean.

The price of many recycled plastics has crashed in recent years due to oversupply, import restrictions and falling oil prices, (amplified by the COVID-19 pandemic). However clean bales of (polyethylene terephthalate) PET and (high-density polyethylene) HDPE are still in demand. In Australia, material recovery facilities currently sort PET and HDPE into separate bales. But small contaminants of other materials (such as caps and plastic labels) remain, making it harder to recycle into high quality new products. Before the price of many recycled plastics dropped, Australia baled and traded all other resin types together as “mixed plastics”. But the price for mixed plastics has fallen to zero and they’re now largely stockpiled or landfilled in Australia.

Beyond Deforestation–Toxic Waste Pollution at the Amazon Rainforest

Maria do Socorro explains in graphic detail the spate of ailments affecting newborns in her remote community in the Amazon: her grandson died after being born with his intestines outside his body, while others were missing organs or had undeveloped bones.  For the 56-year-old community leader, there is little doubt about the cause of these illnesses. She said the rainforest town had for years suffered from toxic waste pollution from the local operations of Norwegian aluminum producer Norsk Hydro.

Long a simmering environmental scandal in Brazil, the allegations were brought on to the international stage in February 2021 when Socorro’s community sued the Norwegian giant in a Dutch court, seeking damages for claims that “the incorrect disposal of toxic waste” from operations in the area had caused a variety of health ailments, polluted the rainforest and destroyed economic opportunities.

“If business can be global, why can’t justice? These companies have businesses everywhere, but then when they do something wrong they want to smother the possibility of people getting compensation,” said Pedro Martins, partner at law firm PGMBM, which is representing 40,000 alleged victims bringing the suit against Norsk Hydro…

Through local entities, Norsk Hydro runs three facilities — a bauxite mine, a refinery and a smelter — in Pará, a vast Amazonian state that is a flashpoint for illegal deforestation, gold mining and land-grabbing.  The company…denied that in 2018 pollutants from its facilities spilled over during heavy rains and polluted nearby rivers and earth….

Locals say bauxite, lead and aluminium pollution have turned the region’s rivers red. A study from the Evandro Chagas Institute, a Brazilian public health body, found in 2018 that the region’s waters were so polluted with industrial waste from the Norsk Hydro facilities that they “cannot be used for recreation, fishing, or human consumption”.

“I invite these Norwegians to come and bathe in our waters. I challenge them. They have good water there in Norway. Our wealth just goes there,” said Socorro, who heads Cainquiama, a group representing mainly indigenous people and quilombolas — the descendants of runaway slaves. Nearly all of the claimants in the suit have complained about chronic pain, hair loss and skin conditions. The suit also contains claims in relation to birth defects, such as those that have affected Socorro’s grandson, who was born with gastroschisis — a hole in the abdominal wall.

The case is a sensitive one for Norwegian investors and the government, which owns a 34 per cent stake in Norsk Hydro. Oslo has long attempted to hold Brasília to account for the environmental destruction of the Amazon, even publishing its own data on deforestation in the world’s largest rainforest.

How Soil Can Fight Pollution

Soil biodiversity is essential for most of the ecosystem services and functions that soils
provide and perform. Soil microbes (i.e., bacteria, fungi) and microfauna (i.e., protozoa
and nematodes) transform organic and inorganic compounds into available forms. These transformations are critical for nutrient cycling and availability, for plants, and other species growth, for cycling of soil organic matter and carbon sequestration, and for the filtration, degradation, and immobilization of contaminants in water and soil.

An important part of the food web is represented by mesofauna, such as springtails and mites, which accelerate litter decomposition and enhance nutrient cycling and availability (especially nitrogen), and predators of smaller soil organisms.

Soil macro, and megafauna such as earthworms, ants, termites, and some mammals act as ecosystem engineers that modify soil porosity, water and gas transport, and bind soil particles together into stable aggregates that hold the soil in place and thus reduce erosion.

Soil biodiversity can mitigate threats to ecosystem services, for instance by acting as a powerful tool in bioremediation of contaminated soils. Biostimulation and bioaugmentation are environmentally sound strategies that contribute to the filtration, degradation, and immobilization of target contaminants. Furthermore, the integral use of organisms such as microbes (bioaugmentation), plants (phytoremediation) and earthworms (vermiremediation) as a bioremediation strategy in hydrocarbon-contaminated soils has proven to be a viable alternative for increasing hydrocarbon removal. On the other hand, soil macrofauna, such as earthworms, termites, and ants, play an important role in improving soil structure and aggregation, which can improve resistance to soil erosion caused by wind and water.

Natural Capital and Human Well-Being

What is the contribution of nature to the economy?… The breathable air, drinkable water and tolerable temperatures that allow humans to do everything they do, and the complex ecosystems that maintain them, tend to be taken for granted. Professor Dasgupta’s review on the Economics of Biodiversity does not seek to play on the heartstrings with tales of starving polar bears. Rather, it makes the hard-headed case that services provided by nature are an indispensable input to economic activity. Some of these services are relatively easy to discern: fish stocks, say, in the open ocean. Others are far less visible: such as the complex ecosystems within soil that recycle nutrients, purify water and absorb atmospheric carbon. These are unfamiliar topics for economists, so the review seeks to provide a “grammar” through which they can be analysed.

The report features its own illustrative production function, which includes nature. The environment appears once as a source of flows of extractable resources (like fish or timber). But it also shows up more broadly as a stock of “natural” capital. The inclusion of natural capital enables an analysis of the sustainability of current rates of economic growth. As people produce GDP, they extract resources from nature and dump waste back into it. If this extraction and dumping exceeds nature’s capacity to repair itself, the stock of natural capital shrinks and with it the flow of valuable environmental services. Between 1992 and 2014, according to a report published by the UN, the value of produced capital (such as machines and buildings) roughly doubled and that of human capital (workers and their skills) rose by 13%, while the estimated value of natural capital declined by nearly 40%. The demands humans currently place on nature, in terms of resource extraction and the dumping of harmful waste, are roughly equivalent to the sustainable output of 1.6 Earths (of which, alas, there is only the one)…Indeed, Professor Dasgupta argues that economists should acknowledge that there are in fact limits to growth. As the efficiency with which we make use of Earth’s finite bounty is bounded (by the laws of physics), there is necessarily some maximum sustainable level of GDP…

Professor Dasgupta hints at this problem by appealing to the “sacredness” of nature, in addition to his mathematical models and analytical arguments.

At Gunpoint in Congo: Is Coltan Worse than Oil?

Tantalum, a metal used in smartphone and laptop batteries, is extracted from coltan ore. In 2019 40% of the world’s coltan was produced in the Democratic Republic of Congo, according to official data. More was sneaked into Rwanda and exported from there. Locals dig for the ore by hand in Congo’s eastern provinces, where more than 100 armed groups hide in the bush. Some mines are run by warlords who work with rogue members of the Congolese army to smuggle the coltan out.

When demand for electronics soared in the early 2000s, coltan went from being an obscure, semi-valuable ore to one of the world’s most sought-after minerals. Rebels fought over mines and hunted for new deposits. Soldiers forced locals to dig for it at gunpoint. Foreign money poured into Congo. Armed groups multiplied, eager for a share.

Then, in 2010, a clause in America’s Dodd-Frank Act forced American firms to audit their supply chains. The aim was to ensure they were not using minerals such as coltan, gold and tin that were funding Congo’s protracted war. For six months mines in eastern Congo were closed, as the authorities grappled with the new rules. Even when they reopened, big companies, such as Intel and Apple, shied away from Congo’s coltan, fearing a bad press.

The “Obama law”, as the Congolese nickname Dodd-Frank, did reduce cash flows to armed groups. But it also put thousands of innocent people out of work. A scheme to trace supply chains known as ITSCI run by the International Tin Association based in London and an American charity, Pact, helped bring tentative buyers back to Congo.  ITSCI staff turn up at mining sites to see if armed men are hanging about, pocketing profits. They check that no children are working in the pits. If a mine is considered safe and conflict-free, government agents at the sites put tags onto the sacks of minerals. However, some unscrupulous agents sell tags on the black market, to stick on coltan from other mines. “The agents are our brothers,” Martin says. It is hard to police such a violent, hilly region with so few roads. Mines are reached by foot or motorbike along winding, muddy paths.

For a long time those who preferred to export their coltan legally had to work with itsci, which held the only key to the international market. Miners groaned that itsci charged too much: roughly 5% of the value of tagged coltan. When another scheme called “Better Sourcing” emerged, Congo’s biggest coltan exporter, Société Minière de Bisunzu, signed up to it instead.

How to Find the True Cost of Water

At current rates of consumption, the demand for water worldwide will be 40% greater than its supply by 2030, according to the UN. Portfolio managers are realizing that physical, reputational and regulatory water risk could hurt their investments, particularly in thirsty industries such as food, mining, textiles and utilities.

One worry is that shocks to supply could drown or dry out a company’s assets. In recent years Coca-Cola has been forced to close plants in India because of drought. In 2019 floods in America’s Midwest caused disruptions at the facilities of two food giants, Cargill and Tyson Foods. A survey by CDP, a non-profit firm, found that 783 big listed companies had faced a total of $40bn of water-related losses in 2018.

Another concern is that the price a company pays for water could rocket. The market price of water does not reflect the environmental and social costs of using it. Government subsidies also mean that companies often do not pay for its true cost. As aquifers are depleted, though, subsidies could become more costly and unpopular, forcing governments to retract them. S&P Global Trucost, a data provider, reckons that if Fortune 500 companies paid the true cost of water, based on estimates of scarcity, rather than current prices, their profit margins would shrink by a tenth. Margins for food, drink and tobacco firms would fall by three-quarters.

Disclosures of water risk are even patchier than those of greenhouse-gas emissions…Established names like Bloomberg and S&P Global are plugging the gap, as are startups. The result is that investors can approach management armed with data rather than questions. “We are getting rid of the black box that companies hide in.” 

Ceres, a non-profit firm, scores businesses on everything from direct water management to risks in the supply chain. Those seeking more detail can use visual tools, such as Bloomberg’s “maps” function, which plots a company’s facilities over a heat map based on water stress. (California is the same color as swathes of sub-Saharan Africa; far-eastern Russia looks a lot like western Europe.) Firms like Aquantix go further, and try to predict the financial cost of water risk.

The accuracy of such forecasts is not yet proven. For Andrew Mason of Aberdeen Standard Investments, though, they are still useful. They show companies that investors care about water risk and encourage them to share data. “This is where carbon was ten or 15 years ago,” he says.

The New Lepers: Oil in Ecuador and Arctic Drilling

Some of Europe’s largest banks are phasing out trading services for the export of oil from the Ecuadorean Amazon, a move that reflects the growing focus of global banks on climate change and their shift away from increasingly risky fossil fuels.

On January 25, 2021, Switzerland’s Credit Suisse Group AG and Holland’s ING said that they were excluding new transactions related to exports of Ecuador’s Amazonian oil from their trading activities, citing climate change and concerns for the Amazon rainforest and its Indigenous people. France’s BNP Paribas SA, the largest bank in the eurozone and one of the region’s trading powerhouses, said in December 2020 that it would immediately exclude from its trading activities the seaborne exports of oil from the Esmeraldas region in Ecuador under its latest environmental finance policies.

Ecuador isn’t one of the world’s top oil producers, but petroleum exports are a key contributor to the country’s economy. Petroecuador, the nation’s state-owned oil company, didn’t respond to requests for comment.  The banks’ flight from Amazonian crude follows last year’s crash in oil prices and growing fears of so-called stranded assets, which are fossil fuels that lose value due to the world’s transition to cleaner forms of energy…

Banks are also facing calls from environmentalists and Indigenous peoples to limit their involvement in fossil fuels. In Ecuador, a campaign by activists and Indigenous people spurred ING and Credit Suisse to reduce their exposure to the Amazonian oil trade. The nonprofits Stand.earth and Amazon Watch published a report in 2020 that called out banks—including ING, Credit Suisse and BNP Paribas—for their financing of Amazonian crude…

Banks and insurers are also cutting ties with Arctic oil drilling. This month, Axis Capital Holdings joined fellow insurers AXA and Swiss Re in pledging not to underwrite any new oil-and-gas drilling in the Arctic Wildlife Refuge in Alaska.  The six biggest U.S. banks— Citigroup Inc., Bank of America Corp. , Goldman Sachs Group Inc., JPMorgan Chase & Co., Morgan Stanley and Wells Fargo & Co.—have also said they would end funding for new drilling and exploration projects in the Arctic.

The Struggle of Managing Dis-Used Nuclear Sources

Two disused radioactive sources, previously employed in cancer treatment, are now in safe and secure storage in the Republic of the Congo, following successful transport and increased security at their temporary storage facility, with the support of the IAEA. The sources no longer emit enough radioactivity to be useful for radiotherapy but are still radioactive and therefore need to be controlled and managed safely and securely. They are expected to be exported outside the country in 2022.

“It took time to understand the risks posed by the disused radiotherapy sources stored for so long in our country…,” said Martin Parfait Aimé Coussoud-Mavoungou, Minister for Scientific Research and Technological Innovation.

Around the world, radioactive material is routinely used to diagnose and treat diseases… This material is typically managed safely and securely while in use; however, when it reaches the end of its useful lifespan, the risk of abandonment, loss or malicious acts grows. 

In 2010, the University Hospital of Brazzaville received a new cobalt 60 (Co-60) sealed source for the hospital’s teletherapy machine, replacing its original source, which was no longer able to deliver effective treatment. The disused sealed source was then packaged and shipped by boat to the supplier. However, the delivery of the package was blocked in transit due to problems with the shipping documents and was returned to the Republic of the Congo. Since 2010, the Co-60 source has been stored at the Autonomous Port of Pointe Noire, one of the most important commercial harbors in Central Africa…

“The August 2020 explosion that occurred in Beirut Harbor reminded the Congolese Authorities of the risks to unmanaged or unregulated material, particularly in national ports and harbors,” said Coussoud-Mavoungou. Congolese decision-makers agreed that the disused source had to urgently leave the Autonomous Port of Pointe Noire.

Following a comprehensive planning and preparation phase, a transport security plan was finalized on location in November 2020, with the support of IAEA experts. They designed a security system for the package and conducted a pre-shipment verification and simulation. At the same time, 45 participants were trained from the five government Ministries involved in the transport by road of the source in Pointe Noire.

Assigning Responsibility for Oil Leaks: Shell’s Deep Pockets

Royal Dutch Shell’s  Nigerian subsidiary has been ordered on January 29, 2021 by a Dutch court to pay compensation for oil spills in two villages in Nigeria…The case was first lodged in 2008 by four Nigerian farmers and Friends of the Earth Netherlands. They had accused Shell and its Nigerian subsidiary of polluting fields and fish ponds through pipe leaks in the villages of Oruma and Goi.

The Court of Appeal in the Hague, where Shell has its headquarters, also ordered the company to install equipment to safeguard against future pipeline leaks. The amount of compensation payable related to the leaks, which occurred between 2004 and 2007, is yet to be determined by the court.  The case establishes a duty of care for the parent company to play a role in the pollution abroad, in this case by having the duty to make sure there is a leak-detection system…

Shell argued that the leaks were caused by sabotage…

In recent years there have been several cases in U.K. courts related to whether claimants can take matters to a parent company’s jurisdiction. In 2019, the U.K. Supreme Court ruled that a case concerning pollution brought by a Zambian community against Vedanta, an Indian copper-mining company previously listed in the U.K., could be heard by English courts. “It established that a parent company can be liable for the actions of the subsidiary depending on the facts,” said Martyn Day, partner at law firm Leigh Day, which represented the Zambians.

The January 2021 case isn’t the first legal action Shell has faced related to pollution in Nigeria. In 2014, the company settled a case with over 15,000 Nigerians involved in the fishing industry who said they were affected by two oil spills, after claims were made to the U.K. High Court. Four months before the case was due to go to trial Shell, which has its primary stock-exchange listing in the U.K., agreed to pay 55 million British pounds, equivalent to $76 million…  

The January 2021  verdict tells oil majors that “when things go wrong they will be held to account and very likely held to account where their parent company is based,” said Mr. Day, adding that the ruling could spark more such actions.

A Present for the Earth: Reducing Plastic Leakage

Approximately 8 million metric tonnes of plastic litter flow to the ocean annually, and only 9% of plastic waste ever produced has been recycled….Another major issue relates to microplastics – those plastics that are smaller than 5 millimeters, and that pose increasing environmental, economic and health hazards… Discarded plastics break down into these smaller particles through natural weathering processes. Microplastics can enter water bodies through different pathways, including atmospheric deposition, run-off from land, roads and through municipal wastewater.

A review of technical solutions from source to sea explores a set of innovative tech solutions. Among these potential technologies include:

  • Introducing debris-cleanup boats, debris sweepers and sea-bins to remove plastics and other wastes carried into water bodies;
  • Protecting large bodies of water by introducing wetlands along coastlines;
  • Secondary and tertiary wastewater treatment which relies on membrane filtration to prevent microplastics entering rivers and lakes;
  • Advanced coagulation technology to make water contaminated with microplastics drinkable;
  • Promoting sustainable waste management practices to reduce plastic leakage.

A key principle of this work is preventing untreated wastewater, which is often packed with plastics and microplastics, from entering the environment in the first place.  The wastewater coming from urban residential, industrial and commercial settings is full of contaminants including plastics, microplastics and other debris…

Time for Burial: Last Repository for Nuclear Waste, Germany

Germany published on September 28, 2020 a list of potential storage sites for radioactive waste as part of its plans to exit nuclear power, dropping the Gorleben salt dome in Lower Saxony from the running.  The 444-page list of sites, to be assessed by 2031 for use from 2050 to hold waste currently in interim storage at nuclear plants, was published by Germany’s Federal Agency for Final Storage (BGE).  Some 90 locations, including parts of Lower Saxony, Bavaria, Baden Wuerttemberg and eastern German states, have been found to be potentially suitable after BGE undertook preliminary mapping that revealed 54% of German territory could be satisfactory.

Taking three years, the process identified salt, clay and crystalline, above all granite, formations, stressing the criteria were science-based, without political influence.  No location was predetermined, said Stefan Studt, head of BGE’s managing board, at a news conference. “Any region in today’s list would take a long, long time to become the actual final space,” he said. Germany had been on a course to exit nuclear power since 2000 but hastened the plan, now set for 2022, following the Fukushima nuclear disaster in 2011.

Gorleben, which became the focus of anti-nuclear protests in the 1970s, failed on three points related to retention, hydrochemical and overall geological qualities, so that it could not be ruled out that aquifers may come into contact with salt, said Steffen Kanitz, a BGE board member.

Banning Gasoline Cars: Better than subsidies and taxes

More than a dozen countries say they will prohibit sales of petrol-fueled cars by a certain date. On September 23rd, 2020,  Gavin Newsom, California’s governor, pledged to end sales of non-electric cars by 2035. Such bans may look like window-dressing, and that could yet in some instances prove to be the case. But in the right circumstances, they can be both effective and efficient at cutting carbon.

Fully electric vehicles are not yet a perfect substitute for petrol-consuming alternatives. They are often more expensive, depreciate faster, and have a lower range of travel and more limited supporting infrastructure, like charging stations or properly equipped mechanics. But the number of available electric models is growing, and performance gaps are closing. A recent analysis concludes that in such conditions—when electric vehicles are good but not perfect substitutes for petrol-guzzlers—a ban on the production of petrol-fueled cars is a much less inefficient way to reduce emissions than you might think.

If electric vehicles were in every way as satisfactory as alternatives, it would take little or no policy incentive to flip the market from petrol-powered cars to electric ones. If, on the other hand, electric cars were not a good substitute at all, the cost of pushing consumers towards battery-powered vehicles would not be worth the savings from reduced emissions. Somewhere in between those extremes, both electric and petrol-powered cars may continue to be produced in the absence of any emissions-reducing policy even though it would be preferable, given the costs of climate change, for the market to flip entirely from the old technology to the new. Ideally, the authors reckon, this inefficiency would be rectified by a carbon tax, which would induce a complete transition to electric vehicles. If a tax were politically impossible to implement, though, a production ban would achieve the same end only slightly less efficiently—at a loss of about 3% of the annual social cost of petrol-vehicle emissions, or about $19bn over 70 years… A shove may work as well as a nudge.

The Industrial Chicken and the US-China Rivalry

Animal diseases, the US-China trade war and covid-19 have all disrupted, or threatened to disrupt, industrial chicken supplies and supply chains…The unsentimental logic of high-performance poultry-rearing is easy to grasp. “White-feather meat chickens”, as they are known in China, grow to 2.5kg in 40 days. Homegrown varieties of “yellow-feather chicken”, descended from backyard fowl, take twice as long to mature and will only ever weigh half as much…

Half a century ago meat in China was a rare luxury. Now, many see it as a daily necessity. In the meantime, the country’s supplies of farmland and clean water have not grown. Agriculture remains blighted by food-safety scandals, the rampant use of fake or illegal animal medicines, and disease outbreaks. Small surprise, then, that Chinese leaders give frequent speeches about food security. A puzzle lurks, though. Leaders also call for self-reliance in key technologies. And in the case of broiler chickens, those two ambitions—rearing meat efficiently and avoiding dependence on imports—are in tension.

The chicken imported into China are the fifth-generation descendants of pedigree birds whose bloodlines represent 80 years of selection for such traits as efficient food-to-meat conversion, rapid growth, strong leg bones and disease resistance. After waves of consolidation, the industry is dominated by two firms, Aviagen (based in Alabama and owned by the ew Group of Germany) and Cobb (owned by Tyson, an American poultry giant).

The most valuable pedigree birds never leave maximum-security farms in America and Britain: a single pedigree hen may generate 4m direct descendants. Their second-generation offspring are flown to breeding sites dispersed between such places as Brazil, Britain and New Zealand, in part to hedge against supply shocks when avian influenzas and other diseases close borders. Day-old third-generation chicks are air-freighted to Jinghai Poultry, a company in China, and other places, which spend six months growing them and breeding them in climate-controlled, artificially lit indoor facilities. In all, China imports 1.6m third-generation white-feather chicks a year.

Jinghai  Poultry hatches 8m fourth-generation, “parent stock” chickens annually. The company sells some to other agri-businesses. It breeds from the rest to produce fifth-generation chicks. These are “meat chickens”, consumed in fast-food outlets, schools and factory canteens, or as chicken parts sold in supermarkets. Yellow-feather chickens, deemed tastier by Chinese cooks, account for most whole birds sold in markets.

Chinese breeders have long tried to create local varieties with bloodlines available in-country… In September 2019, the State Council, China’s cabinet, issued a paper on livestock-rearing that set self-sufficiency in poultry as a goal, calling meat-chicken breeding a priority. Big foreign firms have resisted appeals from officials to send second-generation stock to China….Dependence on foreign bloodlines does carry risks. For several months recently New Zealand was one of the only countries able to send third-generation chicks to China, after other exporters suffered bird-flu outbreaks.

Li Jinghui, president of the China Broiler Alliance, an industry association, calls conditions ripe for China’s “brilliant” scientists to develop local birds… But to develop a domestic breed from scratch would take years, and if it does not meet market needs, a firm could spend a fortune “without much to show for it”…Without a stronger animal-health system and environmental controls, biotechnology alone cannot help China to develop world-class agriculture. Moreover, a long-standing Chinese strategy—bullying foreign firms to hand over intellectual property—is counter-productive now.

1 Million Tons Radioactive Water Release at Sea: Fukushima, Japan

On October 19, 2020, China urged the Japanese government to “cautiously” consider whether to release treated radioactive water in the sea from the Fukushima No. 1 nuclear power plant. China’s remarks came days after it was reported by Japanese media that an official decision on the discharge of the water from the nuclear plant may be made by the end of October 2020. The water has been treated using an advanced liquid processing system, or ALPS, to remove most contaminants other than the relatively less toxic tritium and is stored in tanks on the facility’s premises.

But space is expected to run out by the summer of 2022, with contaminated water increasing by about 170 tons per day. As of September 2020, the stored water totaled 1.23 million tons and continues to grow.

Your Brain on Electro-Magnetic Fields

Current cockpits are flooded with radio frequency (RF) noise from on-board emissions, communication links, and navigation electronics, including strong electromagnetic (EM) fields from audio headsets and helmet tracking technologies. Pilots often report minor cognitive performance challenges during flight, and from 1993 to 2013, spatial disorientation in US Air Force pilots accounted for 72 Class A mishaps, 101 deaths, and 65 aircraft lost. It has been hypothesized that the cockpit RF and EM fields may influence cognitive performance including task saturation, misprioritization, complacency and Spatial Disorientation. However, EM fields and radio waves in cockpits are not currently monitored, little effort has been made to shield pilots from these fields, and the potential impacts of these fields on cognition have not been assessed.

Recent DARPA-funded research has demonstrated that human brains sense magnetic fields, like those used by animals for navigation, and that this process is “jammed” (i.e., disrupted) by radio waves (RF), impacting brainwaves and behavior. Furthermore, recent findings were the first to show that even weak RF fields and “earth strength” magnetic fields have measurable, reproducible effects on human brainwaves and unconscious behavior in a controlled environment. Current tactical audio headsets project magnetic fields up to 10 times earth strength, the effects of which can now be measured experimentally in a similar controlled environment.

[Phase II of the project will involve] developing next generation sensor suite capable of measuring the ambient EM/RF conditions in a military aircraft cockpit environment or a suitably similar analogue. This system must enable measurement of RF intensity vs frequency as well as RF absorption by various tissues in the human body and brain…The goal of Phase II experimentation will be to, not only identify any impacts of the cockpit EM/RF conditions that negatively impact pilot cognitive function or physiological sensor function, but also to develop and test various mitigation strategies to protect against these effects…


If this research and development effort reveals negative impacts of cockpit EM/RF environments on human cognitive function or physiological sensor performance, it is expected to generate interest from the commercial airline industry as well as other industries in which humans are exposed to similar EM/RF conditions

Severe Damage to Beliefs Lasting a Lifetime: covid-19

According to a new study  “Scarring Body and Mind: The Long-Term Belief-Scarring
Effects of COVID-19
” the largest economic cost of the COVID-19 pandemic could arise from changes in behavior long after the immediate health crisis is resolved. A potential source of such a long-lived change is scarring of beliefs, a persistent change in the perceived probability of an extreme, negative shock in the future. Even if a vaccine cures everyone in a year, the COVID-19 crisis will leave its mark on the US economy for many years to come because of the mass revision of beliefs that lasts through a lifetime. Even before the COVID-19 pandemic, people were aware of the disruptive impacts that a pandemic could theoretically have on their lives and the economy. But the tangible, persistent and severe harms associated with an actual pandemic change beliefs about the probability of another similar shock in ways that abstract knowledge cannot.

Living Insecticides: OX5034 Mosquito Obliterates Iteslf

A plan to release over 750 million genetically modified mosquitoes into the Florida Keys in 2021 and 2022 received final approval from local authorities, against the objection of many local residents and a coalition of environmental advocacy groups. The proposal had already won state and federal approval.

Approved by the Environment Protection Agency in May 2020, the pilot project is designed to test if a genetically modified mosquito is a viable alternative to spraying insecticides to control the Aedes aegypti. It’s a species of mosquito that carries several deadly diseases, such as Zika, dengue, chikungunya and yellow fever.  The mosquito, named OX5034, has been altered to produce female offspring that die in the larval stage, well before hatching and growing large enough to bite and spread disease. Only the female mosquito bites for blood, which she needs to mature her eggs. Males feed only on nectar, and are thus not a carrier for disease. The mosquito also won federal approval to be released into Harris County, Texas, beginning in 2021, according to Oxitec, the US-owned, British-based company that developed the genetically modified organism (GMO)…

In 2009 and 2010, local outbreaks of dengue feverleft the Florida Keys Mosquito Control District desperate for new options. Despite an avalanche of effort — from aerial, truck and backpack spraying to the use of mosquito-eating fish — local control efforts to contain the Aedes aegypti with larvicide and pesticide had been largely ineffective.
And costly, too. Even though Aedes aegypti is only 1% of its mosquito population, Florida Keys Mosquito Control typically budgets more than $1 million a year, a full tenth of its total funding, to fighting it…

The new male mosquito, OX5034, is programmed to kill only female mosquitoes, with males surviving for multiple generations and passing along the modified genes to subsequent male offspring….Environmental groups worry that the spread of the genetically modified male genes into the wild population could potentially harm threatened and endangered species of birds, insects and mammals that feed on the mosquitoes.

Forest Infernos and Food Self-Sufficiency

The Mega-Rice Project (MRP) — the conversion of 10,000 square km of peat forest into rice paddies — that was adopted in Indonesia in 1997, was a mega-failure. It produced hardly any rice because the peaty soil lacks the requisite minerals. Instead of spurring farming, the draining of the waterlogged forest with a 6,000km network of canals fuelled fire…. It was the biggest environmental disaster in Indonesia’s history.  Burning peat in 1997 on Kalimantan and the nearby island of Sumatra generated the equivalent of 13-40% of the average annual global emissions from fossil fuels. The MRP was abandoned in 1999 but its legacy endures in the infernos that have ravaged Kalimantan almost every year since.

As work begins in 2020 on the new plantation, is history poised to repeat itself? The government says it has learned from the past. Nazir Foead of the Peatland Restoration Agency says that tractors will steer clear of what remains of Central Kalimantan’s pristine peatlands…but the rest is covered in “shallow peat”, no more than 50cm deep, and so can be cultivated without cataclysm, he says.  Environmentalists are not convinced… Smouldering swamps belch vast amounts of carbon. In 2019, the fires that swept Indonesia emitted 22% more carbon than the conflagration in the Amazon rainforest did. 

But the government argues it must go ahead with the plantation, and quickly, in case covid-19 brings about food shortages… For decades the political elites “have been chasing this ideal of food self-sufficiency”, says Jenny Goldstein of Cornell University. Prabowo Subianto, the defence minister, is one of its greatest champions.

How to Poison a Population: War and Persistent Oil Pollution

Oil pollution in Syria has been a growing concern since the 2011 onset of a civil war that has taken a toll on oil infrastructure and seen rival powers compete over control of key hydrocarbon fields. In the Kurdish-held northeast, a large storage facility in the Rmeilan oil field in Hasakeh province is of particular concern, according to the Dutch peace organisation PAX. [A River of Death, pdf] Oil leaks from the Gir Zero storage facility have been suspected since at least 2014, the latest in March 2020, it said in a June report. Thousands of barrels have leaked out into creeks in the area over the past five years, threatening the health and livelihoods of people in dozens of villages….

The major Rmeilan field controlled by the Kurdish administration, located near a US airbase, has been among the Syrian Kurds’ most prized assets since regime forces withdrew early on in the war. But oil wealth comes at a heavy cost for livestock farmers
whose sheep and cows have died because they drank oil contaminated water.

Residents too suffer heavily from the pollution because  of the foul odour of gas and crude oil wafting over the area… Compounding the situation, makeshift oil refineries have cropped up across the northeast in recent years, dumping oil waste in the waterways…These informal refineries receive oil from nearby fields and process it to provide benzine, gasoline and diesel to locals.

Global Nuclear Waste Movements: from Estonia to Utah

Regulators are weighing whether a local uranium company can import the material for processing at a mill near the border of a Native American reservation. For Energy Fuels Inc , the shipment represents an economic lifeline, after the company posted an operating loss of $7.8 million for the first quarter of 2020. Its president in March 2020 described the U.S. uranium industry as being “on the cusp of complete collapse.”
But for the Ute Mountain Ute Tribe living near the facility – the only operational uranium mill in the United States – the proposal has stoked fears that tribal land will become a dumping ground for global radioactive waste. Both the White Mesa mill and the tribal reservation are in San Juan County, Utah’s poorest.

The mill, built in 1979, was only meant to process conventional uranium ores from the Colorado Plateau for up to 20 years, the tribe says. The Navajo Utah Commission and Navajo Nation have also that the company’s application be rejected. “The state of Utah must recognize and acknowledge the reality that the mill is far past its design life and no longer a conventional uranium mill, but, instead, a radioactive waste dump seeking to operate for decades, if not a millennium,” the Ute Mountain Ute Tribe said in a document submitted to the state….

The 660 tons of powdered material in question, now sitting in 2,000 drums at a plant on the Estonian coast near the Russian border, would be Energy Fuels’ first-ever radioactive import from outside North America. The powder is a byproduct from tantalum and niobium mining by Estonian company Silmet, which contains uranium. But it cannot stay within Estonia, where there is no licensed facility for reprocessing radioactive material. Energy Fuels says there is enough uranium in that byproduct that it is worth processing. Opponents say Energy Fuels is simply taking in waste, which would be stored on site. According to Energy Fuels business from the shipment would help the company keep its 70 workers employed.

Energy Fuels anticipates demand for domestic uranium could rise, after the Trump administration in April 2020 proposed a $1.5 billion federal uranium reserve that would purchase uranium from domestic producers. Such a reserve, however, would need Congressional approval – a major hurdle. The reserve was one of the main proposals to come from a federal Nuclear Fuel Working Group aimed at reviving the U.S. uranium and nuclear industry. The United States currently imports over 90% of its uranium from abroad for its reactors.

Fatalism about Plastics: Intractable Plastics Pollution

The annual inflow of plastic could nearly triple from 2016 to 2040, the study found, and even if companies and governments meet all their commitments to tackle plastic waste, it would reduce the projection for 2040 by only 7%, still a more-than twofold increase in volume.  The study’s authors, the nonprofit Pew Charitable Trust and sustainability consulting firm Systemiq Ltd., set out a range of measures to stem the flow and called on businesses and governments to do more to reduce the use of plastic. 

The study attributes the surge to a growing global population using more plastic per person. Other factors include greater use of nonrecyclable plastics and an increasing share of consumption occurring in countries with poor waste management. China and Indonesia are likely the top sources of plastic reaching the oceans, accounting for more than a third of the plastic bottles, bags and other detritus washed out to sea, according to a study published in 2015 by Jenna Jambeck, an environmental engineer at the University of Georgia.

Over the past two years China has been making strides to improve waste management, including banning the import of plastic and other waste from developed countries like the U.S., which for decades have shipped much of their trash overseas. Indonesia has implemented its own restrictions on trash coming in from overseas, while lawmakers in the U.S. are increasingly trying to find ways to improve the country’s domestic recycling rates as export markets vanish.

They found that flexible plastic packaging—particularly items like potato-chip bags and food pouches, which are made of several materials and typically aren’t recycled—accounts for a disproportionate amount of ocean plastic. The As You Sow report said companies should stop selling products in flexible plastic until it is recycled or composted in significant amounts. Companies, in response, have been redesigning flexible packaging to promote recycling. For example, Nestle recently began selling a line of Gerber baby-food pouches made from a single material. But hurdles remain, particularly around collection and sorting of the packaging…

The amount of plastic flowing into the oceans could be reduced by as much as 80% over the next 20 years through a combination of reduced plastic use, increased recycling, alternatives to problematic packaging like plastic pouches and better waste management, the Pew-Systemiq study said…

Radioactive Water Dumping and Human Rights

In the aftermath of the Fukushima Daiichi nuclear disaster, [UN Special Rapporteurs  have] consistently raised concerns about the approaches taken by the government of Japan. UN Special Rapporteurs have been concerned that raising of “acceptable limits” of radiation exposure to urge resettlement violated the government’s human rights obligations to children.

UN Special Rapporteurs have been concerned of the possible exploitation of migrants and the poor for radioactive decontamination work. Their most recent concern is how the government used the COVID-19 crisis to dramatically accelerate its timeline for deciding whether to dump radioactive wastewater accumulating at Fukushima Daiichi in the ocean

The communities of Fukushima, so devastated by the tragic events of March 11, 2011, have expressed their concerns and opposition to the discharge of the contaminated water into their environment. It is their human right to an environment that allows for living a life in dignity, to enjoy their culture, and to not be exposed deliberately to additional radioactive contamination. Those rights should be fully respected and not be disregarded by the government in Tokyo. The discharge of nuclear waste to the ocean could damage Japan’s international relations. Neighboring countries are already concerned about the release of large volumes of radioactive tritium and other contaminants in the wastewater.

Japan has a duty under international law to prevent transboundary environmental harm. More specifically, under the London Convention, Japan has an obligation to take precaution with the respect to the dumping of waste in the ocean.

Indigenous peoples have an internationally recognized right to free, prior and informed consent. This includes the disposal of waste in their waters and actions that may contaminate their food. No matter how small the Japanese government believes this contamination will be of their water and food, there is an unquestionable obligation to consult with potentially affected indigenous peoples that it has not met…The disaster of 2011 cannot be undone. However, Japan still has an opportunity to minimize the damage…There are grave risks to the livelihoods of fishermen in Japan and also to its international reputation. Again, I urge the Japanese government to think twice about its legacy: as a true champion of human rights and the environment, or not.

Air Pollution: the Microplastics We Breath

 Scientists measured microplastics — tiny particles and fibers of plastic that can float in the air like dust — and found that over 1,000 tons a year are falling into wilderness areas and national parks in the western U.S.  Janice Brahney of Utah State University and her team identified samples of microplastics and other particulates collected over 14 months in 11 national parks and wilderness areas to create the study published in the journal Science, on June 12, 2020.  Pieces of plastic less than 5 mm in length, or microplastics, occur in the environment as a consequence of plastic pollution…

The presence of microplastics in oceans and water supplies has been a matter of concern for some time, but the impact of airborne microplastics is a relatively new area of study. Though microplastics are found nearly everywhere on Earth, the sources and processes behind their ubiquitous distribution, or the “global plastic cycle,” remain vaguely understood.  Initially overlooked, recent studies have suggested that long-range atmospheric transport plays an important role in carrying microplastic pollution vast distances and to remote locations

Examination of weekly wet and monthly dry samples from 11 sites allowed the authors to estimate that more than 1,000 tons of microplastics are deposited onto protected lands in the western U.S. each year, equivalent to more than 123 million plastic water bottles.

The ubiquity of microplastics in the atmosphere has unknown consequences for humans and animals, but the research team observed sizes of particles that were within the ranges that accumulate in lung tissue. Moreover, the accumulation of plastic in the wilderness areas and national parks could well influence the ecosystems in complicated ways.

The Cracks on the Nuclear Runit Tomb

Excerpts from the US Department of Energy Report on the Nuclear Runit Dome

The Runit Dome is a containment structure on Runit Island, located on Enewetak Atoll.  Enewetak Atoll is a former U.S. atmospheric nuclear weapons test site located approximately 2,300 miles west of Hawaii in the northwest Pacific Ocean. The Runit Dome,  which was built in the late 1970s, contains over 100,000 cubic yards of contaminated soil and  debris [from the US nuclear weapons testing] that were encapsulated in concrete inside an unlined nuclear test crater, the Cactus Crater, on the north end of Runit Island. The site has remained a concern to the people of Enewetak. 

The Runit Dome is not in any immediate danger of collapse or failure, and the exterior concrete covering the containment structure is still serving its intended purpose, effectively reducing the natural erosion of the waste pile below by wind and water. Visual surveys of the exterior  concrete of the Cactus Crater containment structure have revealed the presence of cracks and spalls in the concrete cap. However, these cracks and spalls in the exterior concrete cap do not form sites for external or internal radiation exposure that impact or endanger human health or
the environment, or wildlife.

DOE has performed preventative maintenance on exterior surfaces of the containment structure, which will aid in the determination of any changes that
may occur in the condition of the concrete in the future. Any concerns about the imminent failure or collapse of the structure are unfounded.

The main safety concern to humans associated with leakage of radioactive waste from the Cactus Crater containment structure is the uptake of fallout radioactivity in marine foods. There are no data to suggest that the Cactus Crater containment structure, or more specifically, the radioactive material encapsulated in Cactus Crater, is currently having a measurable adverse effect on the surrounding environment or on the health of the people of Enewetak. However, DOE is in the process of establishing a groundwater radiochemical analysis program that is designed to provide scientifically substantiated data that can be used to determine what, if any, effects the dome contents are having, or will have, on the surrounding environment now
and in the future.

Long-term trends in the concentration of Pu in lagoon waters derived from retrospective analysis of a coral core collected off Runit Island show levels of Pu in lagoon waters are systematically decreasing. These data provide compelling evidence that the construction of the Runit Dome has had, and continues to have, a negligible impact on the wider marine environment….

The Cactus Crater containment structure remains vulnerable to wave driven over wash and flooding caused by storm surge and potential effects of sea level rise… It is
anticipated that any measured or modeled effects of storm events may help provide a better understanding of the long-term consequences of sea-level rise on mass-transport of dome derived radionuclides.

Everyone for Themselves: COVID-19 Drug Reserved for U.S.

On June 29, 2020 the US Department of Health and Human Services (HHS) announced an agreement to secure large supplies of the drug remdesivir for the United States from Gilead Sciences through September, allowing American hospitals to purchase the drug in amounts allocated by HHS and state health departments….HHS has secured more than 500,000 treatment courses of the drug for American hospitals through September. This represents 100% of Gilead’s projected production for July (94,200 treatment courses), 90% of production in August (174,900 treatment courses), and 90% of production in September (232,800 treatment courses), in addition to an allocation for clinical trials. A treatment course of remdesivir is, on average, 6.25 vials.

Hospitals will receive the product shipped by AmerisourceBergen and will pay no more than Gilead’s Wholesale Acquisition Price (WAC), which amounts to approximately $3,200 per treatment course.

No Clean-Up, No Justice: Ogoniland, Nigeria

The UN Environment Programme in 2011 proposed the creation of a $1 billion fund to repair the damage done by decades of crude spills in the Ogoniland area in southeastern Nigeria. However, progress has been poor and the little work that has been done is sub-standard, advocacy groups including Amnesty International reported in June 2020.  “Research reveals that there is still no clean-up, no fulfillment of ‘emergency’ measures, no transparency and no accountability for the failed efforts, neither by the oil companies nor by the Nigerian government,” the groups said.

Shell’s Nigerian unit pumped oil in Ogoniland until 1993, when the company withdrew amid increasing protests against its presence. Even though the Hague-based company no longer produces crude in the area, a joint venture operated by Shell Petroleum Development Company, or SPDC, still owns pipelines that crisscross the region.

A government agency responsible for overseeing the clean-up, the Hydrocarbon Pollution Remediation Project, known as Hyprep, was finally set up in 2017 after several false starts, but it’s failing to deliver. …“Hyprep is not designed, nor structured, to implement a project as complex and sizable as the Ogoniland clean-up,” the report cites UNEP as saying in 2019

Oil Spills of Sudan, Humanity for Africa, and East African Court of Justice

The East African Court of Justice delivered in June 2020 a temporary injunction order to the country’s Minister for Justice, the Greater Pioneer Operating Company (GPOC), and the Dar Petroleum Operating Company. The Court approved the application by Hope for Humanity Africa (H4HA), a non-governmental organization (NGO), which sought to highlight the environmental damage caused by oil spills… The NGO contends that: “Over 47,249 of the local population in Upper Nile State and 60,000 in Unity State are at risk of being exposed to the oil pollution this is because the local population depends on the wild foods for survival, the contaminated swamps, streams and rivers waters for cooking, drinking, washing, bathing and fishing.”…

The H4HA is looking for an injunction to stop multiple companies from exporting oil from the region, including CNPC of China, Petronas of Malaysia, and Oil & Natural Gas Corp. of India (ONGC)

The Big Trash Burners: Does it Make Sense to Incinerate Waste?

Global waste is expected to hit 3.4 billion tons by 2050 from 2.01 billion tons in 2016, according to the World Bank. As recycling programs encounter challenges and landfills in the U.S. and Europe reach capacity or face regulations making them more expensive, incinerators are becoming the most viable option for many municipalities to deal with much of their garbage. England now burns more municipal waste than it recycles or landfills. China—already the world’s biggest trash burner—is building more incinerators. And incineration companies say, for the first time in years, expansion projects are on the table in the U.S., although the industry faces significant legal and community challenges. Overall, incinerator-plant capacity is forecast to rise 43% globally between 2018 and 2028, according to Ecoprog, a consulting firm…..

Another growth driver is a European Union target for member states to cap the amount of municipal trash they send to landfill at 10% by 2030. Local communities and environmental groups have launched strong opposition to expansion of incineration plans, citing environmental and public-health concerns. Incinerator plants are also called waste-to-energy plants since the heat from burning trash is used to generate electricity, and many governments classify that electricity as renewable energy, a characterization opponents dispute…..But advocates for clean energy…say that while some energy is recovered by burning, recycling or composting garbage would save far greater amounts of energy.

Critics also say cities that own their incinerator plants have little incentive to pursue waste-reduction efforts because the plants are designed to run at full capacity. “Many countries are over-investing in incineration to cut down on landfilling, which will eventually lock them into burning,” said Janek Vähk, development and policy coordinator for Zero Waste Europe.

Japan’s Nuclear Bombs

On May 13, Japan’s Nuclear Regulation Authority announced that the nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture, had met new safety standards created after the March 11, 2011, earthquake and tsunami….The Rokkasho plant is a 3.8 million square meter facility designed to reprocess spent nuclear fuel from the nation’s nuclear reactors.  Construction began in 1993. Once in operation, the plant’s maximum daily reprocessing capacity will be a cumulative total of 800 tons per year.  During reprocessing, uranium and plutonium are extracted, and the Rokkasho plant is expected to generate up to eight tons of plutonium annually.

Both are then turned into a mixed uranium-plutonium oxide (MOX) fuel at a separate MOX fabrication plant, also located in Rokkasho, for use in commercial reactors. Construction on the MOX facility began in 2010 and it’s expected to be completed in 2022.  Japan had originally envisioned MOX fuel powering between 16 and 18 of the nation’s 54 commercial reactors that were operating before 2011, in place of conventional uranium.  But only four reactors are using it out of the current total of nine officially in operation. MOX fuel is more expensive than conventional uranium fuel, raising questions about how much reprocessed fuel the facilities would need, or want.

The Rokkasho reprocessing plant can store up to 3,000 tons of spent nuclear fuel from the nation’s power plants on-site. It’s nearly full however, with over 2,900 tons of high-level waste already waiting to be reprocessed.

Why has it taken until now for the Rokkasho plant to secure approval from the nuclear watchdog?   Decades of technical problems and the new safety standards for nuclear power that went into effect after the 2011 triple meltdown at the power plant in Fukushima Prefecture have delayed Rokkasho’s completion date 24 times so far. It took six years for the plant to win approval under the post-3/11 safety standards…By the time of the NRA announcement on May 13, 2020, the price tag for work at the Rokkasho plant had reached nearly ¥14 trillion.

Japan is the only non-nuclear weapons state pursuing reprocessing. But as far back as the 1970s, as Japan was debating a nuclear reprocessing program, the United States became concerned about a plant producing plutonium that could be used for a nuclear weapons program.  The issue was raised at a Feb. 1, 1977, meeting between U.S. Vice President Walter Mondale and Prime Minister Takeo Fukuda.  “Reprocessing facilities which could produce weapons grade material are simply bomb factories,” noted a declassified U.S. State Department cable on the meeting. “We want to cooperate (with Japan) to keep the problem under control.”

The U.S. oppose the Rokkasho plant’s construction in 1993, following an agreement in 1988 between the two countries on nuclear cooperation. ..The U.S.-Japan nuclear agreement meant the U.S. would give advance consent for Japan to send spent nuclear fuel to the United Kingdom and France — states with nuclear weapons — for reprocessing until Rokkasho was running at full-scale.

Currently, Japan has nearly 45 tons of plutonium stockpiled, including 9 tons held by domestic utilities. Another 21.2 tons is in the United Kingdom and France is holding 15.5 tons under overseas reprocessing contracts.

Thus, Japan finds itself caught between promises to the international community to reduce its plutonium stockpile through reprocessing at Rokkasho, and questions about whether MOX is still an economically, and politically, viable resource — given the expenses involved and the availability of other fossil fuel and renewable energy resources.

Can Traditional Medicine Cure COVID-19? China’s Take

Around the world officials are advising people to be wary of alternative treatments for covid-19. The opposite is true in China, where remedies known as traditional Chinese medicine (TCM) are being heavily promoted by the state. In January 2020, as the crisis escalated, the health ministry listed TCM treatments among those it recommended for the disease. It sent nearly 5,000 specialists to Hubei to administer them to patients (including sufferers at a sports centre in Wuhan that was turned into a TCM hospital for people with mild symptoms). Now China is keen to promote its remedies abroad.  TCM practitioners have joined Chinese medical teams sent to help manage outbreaks in Cambodia, Iraq and Italy. In mid-March, 2020 state media quoted a Tanzanian health official saying that China’s use of TCM for covid-19 may be “a model” for Africa to follow…

The use of animals in TCM sometimes involves appalling cruelty. One of the TCM remedies that the health ministry has recommended for use in the treatment of covid-19 patients includes powdered bear bile. In China this is often extracted from live bears kept in grim farms even though its active ingredient can be created synthetically. In February 2020 China banned the sale of wild animals as food—close contact in markets between live specimens and merchants may have helped the coronavirus to leap from animal to human. But the new rules do not prevent trappers and breeders from selling animal parts for use in TCM.

Officials do not say that traditional remedies can cure covid-19. But they do claim that TCM can reduce death rates by preventing patients with mild or moderate symptoms from developing more serious ones. They also say that TCM can speed up recovery. A website set up by China Daily, a state newspaper, called “Fighting covid-19 the Chinese way”, says that TCM can “remove the trash which causes illness”, leaving the virus “no room to survive”.

Plastic Bags Back in Vogue: Blame COVID or Plastics Industry?

Plastic bags may make a temporary comback in some places because of COVID-19.
In a setback, albeit temporary, for efforts to combat plastic waste, many state and local governments have suspended plastic bag bans and are prohibiting the use of reusable bags to stem the spread of COVID-19. The plastics industry is pushing for such measures, causing environmentalists to cry foul. San Francisco, which has been at the forefront of single-use plastics restrictions, issued an order “not permitting customers to bring their own bags, mugs, or other reusable items from home” as a measure “to prevent unnecessary contact.” Maine is delaying enforcement of its plastic bag ban to Jan. 15, 2021, after originally planning to roll it out on April 22—Earth Day….

The plastics industry has been advocating for such measures. In recent weeks, Bag The Ban, an initiative sponsored by the American Recyclable Plastic Bag Alliance, has endorsed editorials in newspapers such as the Boston Herald and the New Hampshire Union Leader advocating use of plastic bags to protect grocery workers from COVID-19.

Writing to the US Department of Health and Human Services, the Plastics Industry Association made a similar point. “Single-use plastic products are the most sanitary choice when it comes to many applications.” The association cited research on reusable bags, including a 2011 study from Loma Linda University and the University of Arizona that tested bags from shoppers selected randomly at the grocery store and found bacteria such as E. coli on 8% of them. It also pointed to a 2012 outbreak of norovirus in Oregon linked to use of a reusable food bag and cited a 2019 study from Portugal that found bacteria in bags.

U.S. Desperation for Face Masks: Wild West or Piracy?

From Europe to South America, U.S. allies are complaining about the superpower’s “Wild West” tactics in outbidding or blocking shipments to buyers who have already signed deals for vital medical supplies. …”Money is irrelevant. They pay any price because they are desperate,” one high-level official in German Chancellor Angela Merkel’s ruling CDU/CSU group told Reuters….In April 5, 2020, US President Trump said he was signing a directive to stop the export of N95 respirator masks, which provide essential protection for health-care workers, and other U.S. medical equipment. Furthermore, 3M, a US company, said that the White House had ordered it to stop all shipments to Canada and Latin America of respirators that it manufactures in the U.S., despite what 3M called “significant humanitarian implications.”

In another case, an order of 200,000 masks bound for Germany was diverted to the U.S….Germany’s Secretary of Interior Andreas Geisel called it an “act of modern piracy.” He stated that: “even in times of global crisis, you shouldn’t use Wild West methods.”

Can’t Treat Covid-19 with Flip-Flops

The U.S. Covid-19 response remains a work in progress—fragmented, chaotic, and plagued by contradictory messaging from political leaders, [such as the flip-flops on the use of face masks, see Stop Buying Face Masks , Learn How to Make Your Own Face Mask]. …

 “We don’t have a national plan,” says epidemiologist Michael Osterholm of the University of Minnesota, Twin Cities. “We are going from press conference to press conference and crisis to crisis … trying to understand our response.”…Even if lockdowns succeed at halting the virus…. the United States needs to marshal massive resources to monitor for new outbreaks and quickly contain them…. Identifying cases and contacts and isolating them will require a huge increase in public health workers at the local level….The absence of nationwide coordination highlights the division of legal power between the federal and state governments…. Governors, not federal officials, typically hold police powers to shut businesses and enforce curfews. But many are reluctant to invoke those powers and suffer the political costs without clear direction from above….“The closest comparison here, in terms of national mobilization, is a war. And there is no way the United States would fight a war as 50 separate states.”

Genes that Atttack Plastic

A common fixture in refrigerators, furniture and footwear, polyurethane plastic is pretty much always in high demand. Humans worldwide cycle through millions of tons of the durable substance each year, sending the bulk of what’s not recycled to garbage dumps, where it leaks toxic chemicals into the environment as it very slowly breaks down. At least one of Earth’s organisms sees the stuff as a boon: a bacterial strain called Pseudomonas sp.TDA1. This polyurethane-munching microbe seems to thrive in waste dump sites. Studying the Pseudomonas strain and the chemical strategies it deploys could someday help researchers put a small dent in the world’s plastic problem, which has cumulatively saddled the planet with more than 8 billion tons of slow-degrading synthetic material.

Pseudomonas sp. TDA1 is one of only a few microbes known to be tolerant to polyurethane plastic’s typically toxic properties. What’s more, the bacteria doesn’t just withstand the plastic’s harsh ingredients: it uses some of them as a food source… But while the bacterium can metabolize a subset of the chemicals in polyurethane plastic, it doesn’t seem able to break down these products completely. In-depth studies of Pseudomonas sp. TDA1 will reveal the genes crucial to these plastic-attacking abilities. Understanding how these genes and their products work could help scientists engineer synthetic approaches to tackling plastic in the future.

The Nuclear Reactors Buried in the Deep Sea

The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.

The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

Ethical Killing: Landmines

During the Gulf war of 1991, no fewer than 117,000 landmines were showered over Kuwait and Iraq by American planes. This barely dented the Pentagon’s vast stockpile of 19m. Just under a quarter of the devices scattered in the path of Saddam Hussein’s army were anti-personnel landmines (APLs), the sort that would soon be banned by the Anti-Personnel Mine Ban Convention of 1997, widely known as the Ottawa treaty. The Ottawa treaty has 164 parties, all of which ban the production and use of APL (anti-vehicle mines, among others, are still allowed). America is not among them. When the treaty was finalised, America declined to join (other holdouts include China, Cuba, Iran, Russia and Syria).

Landmines have a number of military uses. They are typically used to channel opposing armies away from particular areas and into others. A minefield can force an enemy to turn, which exposes their flank and makes them especially vulnerable, says Vincent Brooks, a retired general who commanded American forces in South Korea in 2016-18. They can also be used to “canalise” the enemy, channelling attackers into unfavourable terrain, where they may be more exposed to concentrated artillery fire. …But landmines are reviled weapons, and not without good reason. “They’re indiscriminate,”… Landmine casualties have fallen sharply over the years, but at least 2,000 people were killed or wounded by manufactured or improvised APLS in 2018, according to data collected by the Landmine and Cluster Munition Monitor, a research group. Laying a mine can cost a few dollars; clearing one can require $1,000.

The Pentagon has an answer to this. It says that it only possesses, would only produce and would only use “non-persistent” landmines with the capacity to self-destruct or, failing that, to self-deactivate, with a battery losing its charge, within 30 days (some models can blow themselves up in as little as a few hours). It claims that such features are remarkably reliable. …“When the technology is brought into the battlefield, we see that the actual data doesn’t match with the promises,” says Erik Tollefsen, head of Weapons Contamination for the International Committee of the Red Cross. He says that impressive reliability rates are usually derived from tests in sterile conditions, and prove wildly exaggerated in practice. In 2002 a report by the Government Accountability Office, an agency that audits the federal government, noted that during the Gulf war one in 10,000 mines were expected to remain active, which would have produced 12 duds. The actual figure was almost 2,000.

Others argue that there are perfectly viable alternatives to APLs….In particular, remotely activated mines (rather than victim-activated ones) are allowed under the treaty if the person triggering the device has the would-be victim in sight, although this makes them harder to use at range and hostage to a breakdown of communications. In 2018 Finland—a late and reluctant signatory to Ottawa, given its long border with Russia—said it was developing a new, remote-controlled variety of anti-personnel “bounding” mine that leaps into the air and fires metal bullets downward.

Human and Environmental Costs of Low-Carbon Technologies

Substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure.  Such materials include cobalt, copper, lithium, cadmium, and rare earth elements (REEs)—needed for technologies such as solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors…  A majority of the world’s cobalt is mined in the Democratic Republic of Congo (DRC), a country struggling to recover from years of armed conflict…Owing to a lack of preventative strategies and measures such as drilling with water and proper exhaust ventilation, many cobalt miners have extremely high levels of toxic metals in their body and are at risk of developing respiratory illness, heart disease, or cancer.

In addition, mining frequently results in severe environmental impacts and community dislocation. Moreover, metal production itself is energy intensive and difficult to decarbonize. Mining for copper,and mining for lithium has been criticized in Chile for depleting local groundwater resources across the Atacama Desert, destroying fragile ecosystems, and converting meadows and lagoons into salt flats. The extraction, crushing, refining, and processing of cadmium can pose risks such as groundwater or food contamination or worker exposure to hazardous chemicals. REE extraction in China has resulted  threatens rural groundwater aquifers as well as rivers and streams.

Although large-scale mining is often economically efficient, it has limited employment potential, only set to worsen with the recent arrival of fully automated mines. Even where there is relative political stability and stricter regulatory regimes in place, there can still be serious environmental failures, as exemplified by the recent global rise in dam failures at settling ponds for mine tailings. The level of distrust of extractive industries has even led to countrywide moratoria on all new mining projects, such as in El Salvador and the Philippines.

Traditional labor-intensive mechanisms of mining that involve less mechanization are called artisanal and small-scale mining (ASM). Although ASM is not immune from poor governance or environmental harm, it provides livelihood potential for at least 40 million people worldwide…. It is also usually more strongly embedded in local and national economies than foreign-owned, large-scale mining, with a greater level of value retained and distributed within the country. Diversifying mineral supply chains to allow for greater coexistence of small- and large-scale operations is needed. Yet, efforts to incorporate artisanal miners into the formal economy have often resulted in a scarcity of permits awarded, exorbitant costs for miners to legalize their operations, and extremely lengthy and bureaucratic processes for registration….There needs to be a focus on policies that recognize ASM’s livelihood potential in areas of extreme poverty. The recent decision of the London Metals Exchange to have a policy of “nondiscrimination” toward ASM is a positive sign in this regard.

A great deal of attention has focused on fostering transparency and accountability of mineral mining by means of voluntary traceability or even “ethical minerals” schemes. International groups, including Amnesty International, the United Nations, and the Organisation for Economic Co-operation and Development, have all called on mining companies to ensure that supply chains are not sourced from mines that involve illegal labor and/or child labor.

Traceability schemes, however, may be impossible to fully enforce in practice and could, in the extreme, merely become an exercise in public relations rather than improved governance and outcomes for miners…. Paramount among these is an acknowledgment that traceability schemes offer a largely technical solution to profoundly political problems and that these political issues cannot be circumvented or ignored if meaningful solutions for workers are to be found. Traceability schemes ultimately will have value if the market and consumers trust their authenticity and there are few potential opportunities for leakage in the system…

Extended producer responsibility (EPR) is a framework that stipulates that producers are responsible for the entire lifespan of a product, including at the end of its usefulness. EPR would, in particular, shift responsibility for collecting the valuable resource streams and materials inside used electronics from users or waste managers to the companies that produce the devices. EPR holds producers responsible for their products at the end of their useful life and encourages durability, extended product lifetimes, and designs that are easy to reuse, repair, or recover materials from. A successful EPR program known as PV Cycle has been in place in Europe for photovoltaics for about a decade and has helped drive a new market in used photovoltaics that has seen 30,000 metric tons of material recycled.

The Nightmare: Sabotaging 20 Million Nuclear Shipments

Nuclear and other radioactive material is hardest to protect when it is transported from point A to point B — more than half of the incidents of theft of radioactive material reported to the IAEA between 1993 and 2019 occurred while it was in transport.

Around 20 million shipments of nuclear and other radioactive material are regularly transported within countries and across borders each year. These materials are used in industry, agriculture and medicine, as well as in education. Some of them are also radioactive sources that are no longer useful, known as disused sources.

The aim of nuclear security during transport is to ensure that the material is secured throughout and that it is not used for criminal or malicious purposes. While the level of security differs depending on the sensitivity of the material, the fundamental elements of secure transport include physical protection, administrative measures, training and protection of information about the transport routes and schedule. In some cases, escort personnel may also need to be armed

“During conversion of our research reactor from high enriched to low enriched uranium fuel, we had to transport highly radioactive spent reactor fuel from the site to the airport to be sent back to the original manufacturer, and we had to transport the new low enriched uranium fuel from the airport to the facility,” said Yusuf A. Ahmed, Director of the Centre for Energy Research and Training in Nigeria, who was involved in the conversion project. “Although the transport time is only a few hours, there is a lot that can happen during that time, from simple traffic accidents to malicious interventions and sabotage of shipments.”

While only around 30 countries use nuclear power and therefore have significant amounts of nuclear materials to transport, almost all countries use radioactive sources.

Left to their Own Bad Devices: the Future of Ogoni Land in Nigeria

The decades-overdue clean-up of Ogoniland, after years of oil spills from the pipelines that criss-cross the region, is finally under way. But the billion-dollar project — funded by Nigeria’s national oil company and Royal Dutch Shell — is mired in allegations of corruption and mismanagement.  “We are not pleased with what is going on,” said Mike Karikpo, an attorney with Friends of the Earth International and a member of the Ogoniland team that negotiated the creation of the Hydrocarbon Pollution Remediation Project (Hyprep), the government body running the clean-up… 

Nigeria is Africa’s biggest oil producer, pumping out about 1.8m barrels per day. It provides roughly 90 per cent of the country’s foreign exchange and more than half of government revenues.  The clean-up began only the summer 2019, about a year after the first of an expected five tranches of $180m in funding was released to Hyprep. Mr Karikpo complains of a lack of transparency, alleging that planning, budgeting and awarding of contracts took place behind closed doors. Work started at the height of the rainy season, washing away much of the progress as contaminated soil collected for treatment was swept back into the environment…

Ogoniland, like the broader Niger Delta, has become more polluted and development has stalled, with little to show for the billions of dollars in crude that has been extracted. Critics have now accused Hyprep of being, like much of Nigeria’s oil sector, a vehicle for political patronage and graft. This year 16 companies were awarded contracts for the first phase of the clean-up, which — to the consternation of critics — focuses on the least contaminated parts of Ogoniland.

An investigation by the news site Premium Times found that almost all the companies were set up for other purposes, including poultry farming, car sales and construction, and had no experience of tackling oil pollution.  Meanwhile, insiders have questioned Hyprep’s capacity to handle such a massive project…

Shell and Hyprep have rejected the criticism.  Shell, which closed its Ogoniland operations in 1993, said it accepted responsibility “for spills arising from its operations”, but that some of the blame for the pollution must go to thieves who illegally tapped into pipelines and makeshift refining operations in the Delta’s creeks

540 Katrina Oil Spills Equal an Exxon Valdez Disaster

The federal agency overseeing oil and gas operations in the Gulf of Mexico after hurricane Katrina reported that more than 400 pipelines and 100 drilling platforms were damaged. The U.S. Coast Guard, the first responder for oil spills, received 540 separate reports of spills into Louisiana waters. Officials estimated that, taken together, those leaks released the same amount of oil that the highly publicized 1989 Exxon Valdez disaster spilled into Alaska’s Prince William Sound — about 10.8 million gallons…

While hurricanes gain speed due to the effects of climate change, the push for oil leasing in the Gulf of Mexico shows no sign of slowing down. In 2014, the Obama administration opened up 40 million new acres in the Gulf for oil and gas development. Four years later, the Trump administration announced plans to open up most of the rest, in what would be the largest expansion of offshore oil and gas drilling in U.S. history. Many of these 76 million acres are to be offered at reduced royalty rates to encourage additional near-shore drilling in Louisiana waters…

“In the Gulf, storms are predicted to be less frequent but more intense when they do come,” said Sunshine Van Bael, an ecologist at Tulane University who evaluated damage to marsh ecosystems from the BP oil spill. “One thing that storms do is, if oil has been buried underneath the marsh because it wasn’t rehabilitated, a storm could come along and whip that back up to the surface. So, the aftereffects of the oil spills might be greater [with climate change] since the storms are predicted to be more intense.”…

In 2009, a class-action lawsuit against Murphy Oil Corp. ended in a settlement requiring the company to pay $330 million to 6,200 claimants, including owners of about 1,800 homes in St. Bernard Parish. The damage occurred when one of Murphy’s storage tanks floated off its foundation during Katrina and dumped over a million gallons of crude oil into a square-mile segment of Meraux and Chalmette….

To date, more than $19 million has been paid out from the federal Oil Spill Liability Trust Fund to reimburse at least two oil companies for costs they incurred cleaning up oil they spilled during Katrina…

“We don’t normally penalize [companies] for act of God events,” Greg Langley of the Department of Environmental Quality said. “We just get right to remediation.”

Electronic Waste: The Death of Your Phone and the Duty to Resuscitate It

E-waste is the fastest-growing element of the world’s domestic waste stream, according to a 2017 report by the UN’s Global E-waste Monitor. Some 50m metric tonnes will be produced annually in 2020 — about 7kg for every person in the world. Just 20 per cent will be collected and recycled.  The rest is undocumented, meaning it likely ends up in landfill, incinerated, traded illegally or processed in a substandard way. That means hazardous substances spilling into the environment, poisoning the ground and people living nearby.

Heavy metals such as mercury, lead and cadmium — commonly found in LCD screens,  refrigerators and air-conditioning units — as well as chemicals such as CFCs and flame retardants  found in plastics can contaminate soil, pollute water and enter the food chain.  Research last year by Basel Action Network, an NGO, linked toxic e-waste shipped from Europe to  contaminated chicken eggs in Agbogbloshie — a Ghanaian scrapyard where 80,000 residents subsist by retrieving metals from electrical waste. Eating just one egg from a hen foraging in the scrapyard would exceed the European Food Safety Authority’s tolerable daily intake for chlorinated dioxins 220-fold.

Some appliances are more likely to be recycled than others. The recycling rate for big appliances, such as fridges and cookers, is about 80 per cent. That is because they are harder to dispose of and eventually get picked up, even when they are dumped by the kerb. Of small appliances, however,  barely one in five makes it to the recycling centre.  Across the world, governments are trying different ways to reduce e-waste and limit the amount that ends up in landfill.

For some time, EU countries have operated a one-for-one take-back system — which means that distributors need to take back, for free, an older version of any equipment they sell you. But since the rapid rise of online retailers, this has been harder to implement

In the end, all e-waste needs to be reduced to core metals. “It’s a bit like a mining activity.” In certain recycling  plants robots have been programmed to dismantle flatscreen TVs, extracting  precious metals such as cobalt or lithium, whose deposits are limited and increasingly valuable.  “One of the hardest things about recycling is that you are not sure how [the manufacturers] made  it.”   Companies are encouraged  to include this information on their devices. It could be a  file with instructions readable by robots that could then proceed with the dismantling, making the process “easier, cheaper and more circular”. However, manufacturers have so far kept a close guard on the design of their products.

Many pressure groups and lawmakers have concluded that improving recycling rates will not be  sufficient to tackle the global e-waste problem. Increasingly, they are advocating for the right to repair. In October 2019, the EU adopted a package of design measures to make household appliances more repairable.  Starting from March 2021, manufacturers selling certain household appliances will have to ensure  that spare parts are available for a number of years after their product has launched; that their  items can be easily disassembled (and so use screws not glue); and that they provide access to  technical information to repair professionals.

The rules cover appliances including refrigerators, washing machines, dishwashers and televisions.  But they do not extend to IT equipment such as laptops, tablets and mobile phones.  “The road to a new product is very easy, and the road to a successful repair very difficult,” says  Martine Postma, founder and director of Repair Café International Foundation, which celebrated  its 10th anniversary last year. Since its first repair event in Amsterdam in 2009, the organisation  has grown to nearly 2,000 repair groups in 35 countries around the world.  Now, it wants to collect more data about electronic gadgets, to see if it can plot “weak points” in  design that could help manufacturers make them more repairable.

Swept Under the Rug: Radioactive Dust and Brine in the Oil Industry

A salty substance called  “brine,” is  a naturally occurring waste product that gushes out of America’s oil-and-gas wells to the tune of nearly 1 trillion gallons a year, enough to flood Manhattan, almost shin-high, every single day. At most wells, far more brine is produced than oil or gas, as much as 10 times more. Brine collects in tanks, and workers pick it up and haul it off to treatment plants or injection wells, where it’s disposed of by being shot back into the earth

The Earth’s crust is in fact peppered with radioactive elements that concentrate deep underground in oil-and-gas-bearing layers. This radioactivity is often pulled to the surface when oil and gas is extracted — carried largely in the brine…

Radium, typically the most abundant radionuclide in brine, is often measured in picocuries per liter of substance and is so dangerous it’s subject to tight restrictions even at hazardous-waste sites. The most common isotopes are radium-226 and radium-228, and the Nuclear Regulatory Commission requires industrial discharges to remain below 60 for each. Some brine samples registered combined radium levels above 3,500, and one was more than 8,500. “It’s ridiculous that those who haul brine are not being told what’s in their trucks,” says John Stolz, Duquesne’s environmental-center director. “And this stuff is on every corner — it is in neighborhoods. Truckers don’t know they’re being exposed to radioactive waste, nor are they being provided with protective clothing.

“Breathing in this stuff and ingesting it are the worst types of exposure,” Stolz continues. “You are irradiating your tissues from the inside out.” The radioactive particles fired off by radium can be blocked by the skin, but radium readily attaches to dust, making it easy to accidentally inhale or ingest. Once inside the body, its insidious effects accumulate with each exposure. It is known as a “bone seeker” because it can be incorporated into the skeleton and cause bone cancers called sarcomas. It also decays into a series of other radioactive elements, called “daughters.” The first one for radium-226 is radon, a radioactive gas and the second-leading cause of lung cancer in the U.S. Radon has also been linked to chronic lymphocytic leukemia.

Oil fields across the country — from the Bakken in North Dakota to the Permian in Texas — have been found to produce brine that is highly radioactive. “All oil-field workers,” says Fairlie, “are radiation workers.” But they don’t necessarily know it.

The advent of the fracking boom in the early 2000s expanded the danger, saddling the industry with an even larger tidal wave of waste to dispose of, and creating new exposure risks as drilling moved into people’s backyards. “In the old days, wells weren’t really close to population centers. Now, there is no separation,” says City University of New York public-health expert Elizabeth Geltman. In the eastern U.S. “we are seeing astronomically more wells going up,” she says, “and we can drill closer to populations because regulations allow it.” As of 2016, fracking accounted for more than two-thirds of all new U.S. wells, according to the Energy Information Administration. There are about 1 million active oil-and-gas wells, across 33 states, with some of the biggest growth happening in the most radioactive formation — the Marcellus. …

There is little public awareness of this enormous waste stream, the disposal of which could present dangers at every step — from being transported along America’s highways in unmarked trucks; handled by workers who are often misinformed and underprotected; leaked into waterways; and stored in dumps that are not equipped to contain the toxicity. Brine has even been used in commercial products sold at hardware stores and is spread on local roads as a de-icer

But a set of recent legal cases argues a direct connection to occupational exposure can be made… Pipe cleaners, welders, roughnecks, roustabouts, derrickmen, and truck drivers hauling dirty pipes and sludge all were exposed to radioactivity without their knowledge and suffered a litany of lethal cancers. An analysis program developed by the Centers for Disease Control and Prevention determined with up to 99 percent certainty that the cancers came from exposure to radioactivity on the job, including inhaling dust and radioactivity accumulated on the workplace floor, known as “groundshine.”

“Almost all materials of interest and use to the petroleum industry contain measurable quantities of radionuclides,” states a never-publicly released 1982 report by the American Petroleum Institute, the industry’s principal trade group, passed to Rolling Stone by a former state regulator. Rolling Stone discovered a handful of other industry reports and articles that raised concerns about liability for workers’ health. A 1950 document from Shell Oil warned of a potential connection between radioactive substances and cancer of the “bone and bone marrow.” In a 1991 paper, scientists with Chevron said, “Issues such as risk to workers or the general public…must be addressed.”

“There is no one federal agency that specifically regulates the radioactivity brought to the surface by oil-and-gas development,” an EPA representative says. In fact, thanks to a single exemption the industry received from the EPA in 1980, the streams of waste generated at oil-and-gas wells — all of which could be radioactive and hazardous to humans — are not required to be handled as hazardous waste. In 1988, the EPA assessed the exemption — called the Bentsen and Bevill amendments, part of the Resource Conservation and Recovery Act — and claimed that “potential risk to human health and the environment were small,” even though the agency found concerning levels of lead, arsenic, barium, and uranium, and admitted that it did not assess many of the major potential risks. Instead, the report focused on the financial and regulatory burdens, determining that formally labeling the “billions of barrels of waste” as hazardous would “cause a severe economic impact on the industry.”…

There is a perception that because the radioactivity is naturally occurring it’s less harmful (the industry and regulators almost exclusively call oil-and-gas waste NORM — naturally occurring radioactive material, or TENORM for the “technologically enhanced” concentrations of radioactivity that accumulate in equipment like pipes and trucks.”…

In Pennsylvania, regulators revealed in 2012 that for at least six years one hauling company had been dumping brine into abandoned mine shafts. In 2014, Benedict Lupo, owner of a Youngstown, Ohio, company that hauled fracking waste, was sentenced to 28 months in prison for directing his employees to dump tens of thousands of gallons of brine into a storm drain that emptied into a creek that feeds into the Mahoning River. While large bodies of water like lakes and rivers can dilute radium, Penn State researchers have shown that in streams and creeks, radium can build up in sediment to levels that are hundreds of times more radioactive than the limit for topsoil at Superfund sites. Texas-based researcher Zac Hildenbrand has shown that brine also contains volatile organics such as the carcinogen benzene, heavy metals, and toxic levels of salt, while fracked brine contains a host of additional hazardous chemicals. “It is one of the most complex mixtures on the planet,” he says…

“There is nothing to remediate it with,” says Avner Vengosh, a Duke University geochemist. “The high radioactivity in the soil at some of these sites will stay forever.” Radium-226 has a half-life of 1,600 years. The level of uptake into agricultural crops grown in contaminated soil is unknown because it hasn’t been adequately studied.

“Not much research has been done on this,” says Bill Burgos, an environmental engineer at Penn State who co-authored a bombshell 2018 paper in Environmental Science & Technology that examined the health effects of applying oil-field brine to roads. Regulators defend the practice by pointing out that only brine from conventional wells is spread on roads, as opposed to fracked wells. But conventional-well brine can be every bit as radioactive, and Burgos’ paper found it contained not just radium, but cadmium, benzene, and arsenic, all known human carcinogens, along with lead, which can cause kidney and brain damage.

Brine as dust suppressant

Ohio, because of its geology, favorable regulations, and nearness to drilling hot spots in the Marcellus, has become a preferred location for injection wells. Pennsylvania has about a dozen wells; West Virginia has just over 50. Ohio has 225. About 95 percent of brine was disposed of through injection as of 2014. Government scientists have increasingly linked the practice to earthquakes, and the public has become more and more suspicious of the sites. Still, the relentless waste stream means new permits are issued all the time, and the industry is also hauling brine to treatment plants that attempt to remove the toxic and radioactive elements so the liquid can be used to frack new wells.

The Global Experiment with Malaria Vaccine Starts in African States

Thirty years in the making, RTS,S, the malaria vaccine, also known by its brand name, Mosquirix, targets Plasmodium falciparum, the most common and most lethal of four malaria parasite species. It is an answer to a dire need. After decades of declining numbers of cases and deaths, the fight against malaria has stalled. Parasites resistant to the most widely used treatment, called artemisinin-based combination therapy, are spreading, while malaria mosquitoes are increasingly resistant to insecticides. And yet the rollout in Malawi and in two other African countries, isn’t quite the breakthrough the field has been waiting for. Mosquirix’s efficacy and durability are mediocre: Four doses offer only 30% protection against severe malaria, for no more than 4 years. Some experts question whether that is worth the cost and effort

The biggest concerns, however, are about the vaccine’s safety. In the largest trial, children who received Mosquirix had a risk of meningitis 10 times higher than those who received a control vaccine. Mosquirix may not have triggered the meningitis cases—there are other possible explanations—but the possible risk worried the global health community so much that, rather than rolling out the vaccine across Africa, the World Health Organization (WHO) has decided to set up a pilot in Malawi, Ghana, and Kenya in which the vaccine will be given to hundreds of thousands of children.

The Malaria parasite  is a challenging target for a vaccine. It has a complex life cycle that begins when an infected female mosquito bites a human and spits Plasmodium cells called sporozoites into the bloodstream. They multiply in the liver, emerge as another cell type named merozoites, invade red blood cells, and continue to multiply. The blood cells burst, causing fever, headache, chills, muscle aches, and often anemia. (They also flood the blood with gametocytes—the parasite’s reproductive cells—ready to be picked up by the next mosquito.) Along the way, the parasite frequently changes its surface proteins. That makes it an elusive target for the immune system, and for a vaccine.

Mosquirix, developed in the 1980s by a team in Belgium at SmithKline-RIT, now part of GlaxoSmithKline (GSK), stimulates an immune response against a protein that occurs only on the sporozoites’ surface. To bolster the response, the research team fused the vaccine protein with a hepatitis B surface protein and added an adjuvant….

A relative outside, Danish anthropologist and vaccine researcher Peter Aaby of the Bandim Health Project in Guinea-Bissau, offered another argument against introduction. After reanalyzing the data from the biggest trial, Aaby discovered that although the vaccinated children had malaria less often, they did not die less often. Among girls, overall mortality was almost doubled, Aaby told his colleagues at the meeting. “This vaccine is killing girls,” he recalls saying. Whereas WHO expects the vaccine to save one life per 200 children vaccinated, Aaby believes one in 200 will die as a result of it; he predicts “a nightmare.”

Aaby and Christine Stabell Benn, a global health professor at the University of Southern Denmark, have an explanation. The married couple has studied routine vaccinations in Africa for decades and believes vaccines can “train” the immune system in ways that don’t affect just the target disease. Vaccines that contain a living, weakened pathogen—such as the vaccines against measles and tuberculosis—strengthen the immune system generally, Aaby and Stabell Benn say, making recipients better able to fight off other infections. But vaccines that contain a killed pathogen or only bits of it weaken the immune system, their theory goes—especially in girls, because their immune systems seem to respond more strongly to vaccines in general.

Does Fracking Cause Cancer? The Right to Know and the Duty to Protect

An increase in the number of teens and young adults diagnosed with a rare cancer in the southwest corner of Pennsylvania has caused the state to look for a link between fracking and the disease.The investigation was sparked by a spate of Ewing’s sarcoma cases in and around Washington County, which has more Marcellus Shale gas wells than any other county in the state. In April 2019 state Department of Health found that the cases didn’t constitute a statistically significant cancer cluster. But affected families and other residents lobbied the governor for an investigation.

 The region is home to coal mining, oil drilling, chemical plants and a former uranium-processing facility.  Each year, about 250 children in the U.S. are diagnosed with Ewing’s sarcoma, a rare cancer of the bone or surrounding soft tissue, according to the National Institutes of Health.  In four counties in southwest Pennsylvania, 31 people were diagnosed with Ewing’s sarcoma from 2006 through 2017, according to state cancer data. That is a roughly 40% increase from the period from 1995 through 2005, when 22 people in the same area were diagnosed, according to state data. Residents point to two additional cases in 2018. Most troubling to many local residents is that the six cases in Washington County since 2008 occurred in one school district.

Other communities are studying potential health risks of fracking. In October 2019, Colorado regulators said they would tighten regulation of drilling after a state-funded study found that people living within 2,000 feet of oil-and-gas wells could have, in worst-case scenarios, an elevated risk for infrequent, short-term health effects such as nosebleeds and headaches from emissions.

Evelyn Talbott, a professor of epidemiology at the University of Pittsburgh, said Pennsylvania investigators should look at residents’ potential exposures to chemicals and to radiation from natural-gas sites. She said they also should look at the sealed waste site of the defunct uranium-processing plant…Since Pennsylvania’s first Marcellus Shale well was drilled in Washington County in 2003, more than 1,800 wells have been fracked there. Compressor stations, processing plants and pipelines have followed. Some residents worry that pollutants such as benzene from air emissions or radium from wastewater could affect people’s health.

Imperfect Tools Used Imperfectly: 400 000 Malaria Deaths

According to a report, published on December 4th, 2019 by the World Health Organization,  there were 228 million cases of malaria in 2018, which resulted in 400,000 deaths. Most victims were young children in Africa. That is a far cry from targets set in 2015 for the near-elimination of malaria by 2030.  These targets depended on a $6 billion a year being poured into malaria-control efforts. Funding in recent years, however, has been about $3 billion a year. More money would surely help. But substantial gains can be made by doing things more efficiently—something at which malaria programmes have been dismal.

Stopping malaria relies on three things: insecticide-treated bed nets to prevent nocturnal mosquito bites; the spraying of homes with insecticides; and the treating of pregnant women and children with rounds of preventive medication. These are all “imperfect tools, often used imperfectly”, says Pedro Alonso, head of the malaria programme at the World Health Organisation. Countries usually deploy the same package of measures everywhere, even though infection rates and their seasonal patterns vary a lot between regions, and particularly between cities and the countryside. Transmission reaches a peak in the rainy season, when mosquitoes are abundant, so preventive mass-treatment of children then can make a huge difference. Regional variations are particularly pronounced in large countries like Nigeria—a place that, by itself, accounts for a quarter of the world’s malaria cases.

The typical approach of a malaria-control programme is to bombard a country with bed nets and then use whatever cash remains for sporadic rounds of preventive medication. But in many big cities, such as Dar es Salaam and Nairobi, cases are few and far between, so deploying nets there is a waste. Overspending on nets at the expense of other things happens partly because nets are easy to count—a feature that aid programmes are particularly fond of. Results which cannot be attributed directly to money a donor spends tend to fall further down that donor’s list of priorities. This kind of reasoning tips the scales, because foreign aid accounts for two-thirds of the money spent on malaria.

Ethical Mining 2020

Less than half of the world’s larger miners have released safety and environmental details about their mine-waste dams, showing the mixed success of investors’ demands for greater transparency after the deadly Brumadinho dam collapse in Brazil. In January, 2019, 270 people died following the collapse of a tailings dam owned by Brazil’s Vale SA. The incident prompted a coalition of investors who manage more than $13 trillion to ask 726 companies in the mining and oil-sands business to disclose information on their dams. Nearly 55% of companies hadn’t delivered as of November 2019. While some of the largest miners—including Vale, BHP , and Anglo American have disclosed their information, others have yet to do so. Investors are increasingly examining ethical issues when looking at mining.

Tailings, the waste material from extracting valuable minerals, are often held for decades behind dams that can be risky if they are poorly constructed, ill-maintained or filled with too much waste. Major failures of tailings dams have become more frequent as mining companies ramp up production to meet the world’s growing demand for commodities. Norilsk Nickel one of world’s most valuable miners with a market capitalization of roughly $43 billion, hasn’t publicly released details on its tailings dams. In 2016, heavy rainfall caused a Norilsk Nickel tailings dam in northern Russia to overflow, coloring a local river red. Miners of potash and phosphate—minerals used mainly in fertilizers—have been slow to disclose.

Another big company that has not released details is Canada-based Nutrient. Satellite images show two of the company’s six Saskatchewan mines are located a few miles from residential communities and one neighbors a bird-breeding area. A tailings pond at the company’s North Carolina phosphate mine is located next to the Pamlico River, which feeds into the state’s largest estuary.

In 2017, Israel Chemicals reported that the partial collapse of a subsidiary’s dike in Israel released 100,000 cubic meters of acidic wastewater that flowed into a nearby nature reserve. The wastewater resulted from the production of phosphate fertilizer.Vancouver-based Imperial Metals Corp.is tied to what is considered one of Canada’s worst environmental catastrophes. In 2014, a British Columbia dam owned by the company burst, sending some 25 million cubic meters of mining waste pouring into a pair of glacial lakes

Large Chinese miners such as Jiangxi Copper, Zijin Mining Group Co.  and Zhongjin Gold Corp. also haven’t shared information with the investor coalition. There are 8,869 documented tailings dams, of which 16% are within about half a mile of a residential area, school or hospital, according to research led by the School of University of Science and Technology in Beijing. Karen Hudson-Edwards, a mining specialist at Britain’s University of Exeter, said the actual number in China is estimated at around 12,000 dams and there is little transparency on tailings risk in the country. There have been at least 12 serious tailings-dam accidents in China since the 1960s, with one in 2008 killing 277 people, according to the World Information Service on Energy, a Netherlands-based nonprofit.

How to Lose Track of 250 barrels of Radioactive Waste — Los Alamos National Laboratory

The Triad National Security,*** the company in charge of Los Alamos National Laboratory’s (LANL) operations in 2018 lost track of 250 barrels of mixed hazardous waste on their way to the Waste Isolation Pilot Plant (WIPP) in Carlsbad. Mixed waste contains low-level radioactive waste and other hazardous materials. Failing to track such a high volume of waste is an egregious error that falls in line with the lab’s long history of serious missteps.  “The fact that LANL has mischaracterized, misplaced, mis-inventoried — or whatever — 250 barrels of waste is pretty astounding,” said Jay Coghlan, executive director of Nuclear Watch New Mexico.

Still, Triad has committed less than a tenth of the violations that its predecessor, Los Alamos National Security LLC, used to average in a given year.  A disastrous “kitty litter” incident happened under Los Alamos National Security, in which a waste barrel was packaged in error with a volatile blend of organic cat litter and nitrate salts, causing the container to burst and leak radiation at the Southern New Mexico storage site. WIPP closed for almost three years, and the cleanup cost about $2 billion.

***Triad is a public service oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), The Texas A&M University System (TAMUS), and The Regents of the University of California (UC).

Denizen Nuclear Waste: the Orchid Island

Several members of the Tao Aboriginal community in Taiwan reiterated their decades-long demand that the government remove nuclear waste from Taitung County’s Orchid Island saying that they would not accept the NT$2.55 billion (US$83.57 million) in compensation.  Since construction of a storage site was finished in 1982, more then 100,000 barrels of low-level radioactive waste have been transported from nuclear power plants on Taiwan proper to the outlying island, without obtaining residents’ consent in advance….  [According to the community], the government should establish a platform to discuss how to handle the nuclear waste and related compensation, while also continuing to reveal the storage site’s buried history

The Jihadist Mafia: Controlling the Gold of Sahel

Burkina Faso is struggling to contain a fast-growing jihadist insurgency. Along with Mali and Niger, it has become the main front line against terrorists in the Sahel, a dry strip of land that runs along the edge of the Sahara. This year alone the conflict has killed more than 1,600 people and forced half a million from their homes in Burkina Faso….A worrying new trend is a battle by jihadists and other armed groups to take control of the region’s gold rush.

Although gold has long been mined in the region…it has boomed in recent years with the discovery of shallow deposits that stretch from Sudan to Mauritania. International mining companies have invested as much as $5bn in west African production over the past decade, but the rush has also lured hundreds of thousands of unsophisticated “artisanal” miners. The International Crisis Group (ICG), an NGO, reckons that more than 2m people are involved in small-scale mining in Burkina Faso, Mali and Niger. In total they dig up 40-95 tonnes of gold a year, worth some $1.9bn-4.5bn.

Artisanal Mining’s Claustrophobic Conditions

This rush—in a region where states are already weak and unable to provide security—has sucked in a variety of armed groups and jihadists, including the likes of Ansar Dine and Islamic State in the Greater Sahara…The jihadists probably have direct control of fewer than ten mines…But they have influence over many more. In some areas artisanal miners are forced to pay “taxes” to the jihadists. In others, such as Burkina Faso’s Soum province, the miners hire jihadists to provide security… Other armed groups such as ethnic militias are also in on the bonanza and collect cash to guard mines. International mining firms may also be funding the jihadists by paying ransoms for abducted employees or “protection” money to keep mining, according to a study published by the OECD, a club of mostly rich countries.

For the moment much of Burkina Faso’s artisanal production is sneaked into Togo… Togo does not produce much gold domestically but it sent more than 12 tonnes of gold to Dubai in 2016. Gold is also taken out of the Sahel through major airports in hand luggage.

How to Engineer Bacteria to Search for Underground Chemical Weapons: DARPA

U.S. military researchers asked in 2019 two companies to develop new kinds of biological sensors that can detect underground disturbances or the presence of buried chemicals or weapons.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are looking to Raytheon BBN Technologies, and Signature Science, for the BioReporters for Subterranean Surveillance program.  This project seeks to use indigenous and engineered organisms to sense changes of interest to military commanders in natural and built environments. Raytheon BBN and Signature Science won separate $1.6 million contracts for the Subterranean Surveillance progam.

The two companies will perform laboratory research and proof-of-concept demonstrations of biological sensing systems in well- controlled field tests that take advantage of recent advances in microbial science and synthetic biology to develop biological sensors, signal transducers, and reporters that can reveal subterranean phenomena at a distance.  Bio Reporters should be able to sense a phenomenon at least one meter below the surface, propagate a signal to the surface within seven days, and be continuously detectable on the surface at a distance of 10 meters over the subsequent seven days.

DARPA researchers want Raytheon BBN and Signature Science experts to take advantage of the extensive biological networks that exist underground to monitor large areas to increase the military’s ability to detect subterranean events without the need for precise coordinates.

Excerpts from John Keller, Researchers eye new biological sensors to to detect underground objects like buried chemicals and weapons, https://www.militaryaerospace.com,  Nov. 6, 2019

In more detail  Signature Science and its partner, the Texas A&M University Center for Phage Technology, aim to leverage modern and synthetic phage biology and the straightforward molecular genetics of the harmless soil bacterium Bacillus subtilis to generate a new platform to recognize and report on specific chemical threats underground. The Spore-Phage Amplified Detection (SPADe) method, potentially extensible to explosives, radiation or physical disturbance sensing, seeks to substantially advance currently used techniques which rely heavily on manual soil testing. 

Scrubbing Sulfur Pollution

From January 2020, the United Nations International Maritime Organization (IMO) will ban ships from using fuels with a sulphur content above 0.5%, compared with 3.5% now.The rules herald the biggest leap in how ships are powered since they switched from burning coal to oil over a century ago, but vessels will still be allowed to use higher-sulphur fuel if fitted with cleaning devices called scrubbers.  Closed-loop scrubbers keep most of the water used for sulphur removal onboard for disposal at port. Open-loop systems, however, remove sulphur coming through a ship’s smokestack with water that can then be pumped overboard.

Years of studies have examined whether open-loop scrubbers introduce into waterways acidic sulphur harmful to marine life, cancer-causing hydrocarbons, nitrates leading to algal blooms and metals that impair organ function and cause birth defects.  The results have largely been inconclusive and the IMO itself has encouraged further study into the environmental impact of scrubbers.

The stated aim of the new IMO measures is to improve human health..  A study in the journal Nature last year found ship emissions with current sulphur levels caused about 400,000 premature deaths from lung cancer and cardiovascular disease as well as around 14 million childhood asthma cases every year.

Singapore and Fujairah in the United Arab Emirates have banned the use of open-loop scrubbers from the start of next year. China is also set to extend a ban on scrubber discharge to more coastal regions.

Rivers of Crude Oil: the poisoned land of Iraq

A biological remediation pilot project seeking to enhance nature’s own ability to clear up oil spills in Iraq’s conflict-affected areas has been launched in Kirkuk, Iraq…This UNEP initiative seeks to harness naturally occurring soil bacteria as a powerful natural ally to decontaminate poisoned land.  Over three years ago in summer 2016, the residents of Qayyarah—a small town of around 25,000 people, some 60 km south of Mosul—were caught in the line of fire as so-called Islamic State fighters torched nineteen nearby oil wells. So thick were the clouds of smoke, that people could not distinguish day from night for weeks in what infamously came to be known as the “Daesh winter”.  Rivers of crude oil flowed through Qayyarah’s streets and into seasonal wadis as oil wells spewed tens of thousands of barrels of oil relentlessly for months. The specter of an even worse environmental catastrophe was heightened as the oil slick migrated to less than three kilometers from the Tigris River, Iraq’s water lifeline.

Following an epic battle to control the oil fires that took nearly a year, North Oil Company, which manages the oil fields of northern Iraq, is currently collecting an estimated 20,000 tonnes of remaining oil waste in Qayyarah into around a dozen large pits.  Progress, however, has been slow and pools of heavy viscous oil remain on the doorsteps of entire neighborhoods and households, who complain about the impacts of noxious fumes on their children’s health.

“In some places, the layer of heavy oil is two to three meters thick, and long stretches of wadi channels are now effectively tarmac roads on which cars can be driven,” observed Mohammed Dawood, head of Qayarrah oil refinery’s environmental unit. Furthermore, Environment Ministry officials expressed concern that exceptionally heavy rains and flash floods of the 2018/19 winter season washed out oil from the holding pits into the Tigris River.

While oil production restarted in Qayyarah immediately after the conflict ended in June 2017, reaching currently an estimated 40,000 barrels per day, little has been done to clean up the conflict’s toxic aftermath… The UN Environment Programme in collaboration with the UN Assistance Mission in Iraq delivered a four-day hands-on training workshop on remediation of oil spills by the use of bacteria  in September 2019. “By adding nutrients from manure, bulking agents like wood chips and water, we are simply creating the ideal conditions for bacteria to thrive and speeding up the natural process of breaking down the oil,”

The Impact of Oil Spills on the Deep Sea: the Deepwater Horizon Oil Spill

The Louisiana University Marine Consortium (LUMCON) published in September 2019 a study on the Deepwater Horizon Oil Spill in Royal Society Open Science.  The BP’s Deepwater Horizon oil rig exploded in April 2010, killing 11 workers.  The subsequent cleanup and restoration had cost nearly $65 billion..but while while we can burn off and disperse oil on the surface, but we don’t have the technology to get rid of oil on the seafloor. So approximately 10 million gallons of it settled there….In 2017 , the The LUMCON surveyed the site surrounding the wreck of the rig, and another one 1,640 feet north. There were no giant isopods, glass sponges, or whip corals that would have jumped (metaphorically) at the chance to colonize the hard substrate of the rig, such as discarded sections of pipe…..But]  crabs were just about everywhere. The researchers were shocked by the sheer number of crustaceans and other arthropods that had colonized the spill site. According to rough estimates, Atlantic deep sea red crabs, red shrimp, and white caridean shrimp were nearly eight times more populous at the Deepwater site than at other spots in the Gulf. “Everywhere there were crabs just kicking up black plumes of mud, laden with oil,” Nunnally says. But abundance does not mean the site was recovering, or even friendly to life. Particularly eerie was the crab’s achingly slow movement. “Normally, they scatter when they see the ROV lights,” he says. But these crabs seemed unbothered, or unaware of the robot’s presence.

Crabs on the seabed of the Deepwater Horizon oil spill

The researchers hypothesize that degrading hydrocarbons are what’s luring unwitting crabs from the surrounding seafloor to the deep-sea equivalent of a toxic dump. “The chemical makeup of oil is similar to the oils naturally present on crustaceans,” Nunnally says. “They’re attracted to the oil site, but everything goes downhill for them once they’re in the area.” A similar kind of chemical confusion occurred at an oil spill in Buzzards Bay in New England in 2003, which attracted hordes of American lobsters. The researchers liken the death trap to the La Brea Tar Pits: Once lured in, the crabs lose their ability to leave. With no other species able to thrive in the area, the crabs have no food source—except each other. And as one might imagine, consuming the flesh of a toxin-riddled crab or starving to death in a deep-sea tar pit is sort of a lose/lose situation.

The crabs also looked anything but normal: some claws shrunken, some swollen, shriveled legs, a dusting of parasites. “There were deformities, but mostly things were missing,” Nunnally says. “You come in with eight legs and try to get away on four or five.” The researchers have yet to ascertain what specific toxins led to these maladies. The shrimp looked just as awful as the crabs. “They didn’t look like shrimp from other sites,” Nunnally says, adding that many of the small crustaceans had humps in their backs—tumors, perhaps.

The Fight Against Toxic Algae

Signs posted around the Grand Lake, Ohio read: “Danger: Avoid all contact with the water.”  When dangerously high levels of toxins from blue-green algae in Grand Lake, Ohiio were publicized in 2009, many residents and tourists stopped using the 13,000-acre lake in northwest Ohio. Hotel revenue and home values sank for several years as algae bloomed in the state’s largest inland lake.

Greenish water still laps at Grand Lake’s shores, but recent water samples show that the amount of algae-feeding nutrients entering the lake is down significantly. State, federal and private donations covered more than $10 million in projects aimed at improving water quality. More people are boating on the lake again. Grand Lake could now serve as an example for communities with algae problems across the nation, experts say.

Algal blooms are on the rise, from Lake Erie to the Florida Everglades. In August 2019, the Environmental Protection Agency listed algae-related beach closures or health advisories in 23 states, and it said other blooms may not have been reported. In 2010, the EPA found that 20% of 50,000 lakes surveyed had been affected by phosphorous and nitrogen pollution, which feeds algae.e  Cleaning up bodies of water choked with toxic algae has proved difficult. The project to repair Grand Lake, once one of the most polluted by algae in the nation, is one of the clearest successes. It shows cleanup is possible, but also expensive and time-consuming.

“It’s not restored yet, but it’s on the road to recovery,” said Stephen Jacquemin, an associate professor of biology at Wright State University-Lake Campus in Celina.  Beginning in 2012, wetlands areas were built around the lake, which was hand dug in the 1830s. The thick stands of bulrushes and other plants have reduced phosphorous and nitrogen levels in water entering the wetlands before reaching the lake by as much as 90%, Dr. Jacquemin said.  Three wetland areas, which cost a total of about $6 million to build, are constructed as a series of interconnected pools that allow particulates to settle out and plants and microbes to remove nutrients.

 The state’s Department of Natural Resources has also dredged the lake bottom to remove nutrient-loaded sediment, and tried to clean up one of Grand Lake’s beaches near St. Marys by building a rock jetty and installing aerators and a curtain to filter water. Recent water tests there showed levels below 6 parts per billion of the toxin microcystin, under Ohio’s threshold of 20 parts per billion for avoiding contact with water.

The Truth About Forest Fires

BBC has used satellite data to assess the severity of fires in Brazil, Indonesia, Siberia and Central Africa.  It has concluded that although fires in 2019 have wrought significant damage to the environment, they have been worse in the past.   More than 35,000 fires have been detected so far in 2019 in East Asia  spreading smoky haze to Malaysia, Singapore, the south of Thailand and the Philippines, causing a significant deterioration in air quality.  But this is substantially fewer than many other years including those, such as 2015, exacerbated by the El Nino effect which brought unusually dry weather.

Haze Pollution

In Indonesia, peatland is set alight by corporations and small-scale farmers to clear land for palm oil, pulp and paper plantations, and can spread into protected forested areas.  The problem has accelerated in recent years as more land has been cleared for expanding plantations for the lucrative palm oil trade.  Old palm trees on plantations that no longer bear fruit are often set on fire to be replaced by younger ones.

The number of recorded fires in Brazil rose significantly in 2019, but there were more in most years in the period 2002 to 2010.  There is a similar pattern for other areas of Brazilian forestry that are not part of the Amazon basin.  For 2019, we have data up to the end of August, and the overall area burnt for those eight months is 45,000 sq km. This has already surpassed all the area burnt in 2018, but appears unlikely to reach the peaks seen in the previous decade… “Fire signals an end of the deforestation process,” says Dr Michelle Kalamandeen, a tropical ecologist on the Amazon rainforest.  “Those large giant rainforest trees that we often associate with the Amazon are chopped down, left to dry and then fire is used as a tool for clearing the land to prepare for pasture, crops or even illegal mining.”

The environmental campaign group Greenpeace has called the fires that have engulfed the Russian region of Siberia this year one of the worst outbreaks this century.  The cloud of smoke generated was reported to have been the size of all the European Union countries combined.  Forest fires in Siberia are common in the summer, but record-breaking temperatures and strong winds have made the situation particularly bad.  Russia’s Federal Forestry Agency says more than 10 million hectares (100,000 sq km) have been affected since the start of 2019, already exceeding the total of 8.6 million for the whole of 2018…. Drawing on data for the number of fires, it is clear that there have been other bad years, notably in 2003.

Nasa satellites have identified thousands of fires in Angola, Zambia and DR Congo.However, these have not reached record levels.  “I don’t think there’s any evidence that the fires we’re seeing in Africa are worse than we’ve seen in recent years,” Denis McClean, of the UN Disaster Risk Reduction agency, told the BBC.  According to data analysed by Global Forest Watch, fires in DR Congo and Zambia are just above average for the season but have been higher in past years.  In Angola, however, fires have been reported at close to record levels this year.

Some have drawn comparisons with the situation in the Amazon, but the fires in sub-Saharan Africa are different.  Take DR Congo – most fires are being recorded in settled parts of the country’s southern, drier forest and savannah areas, and so far not in tropical rainforest.  Experts say it is difficult to know what is causing these fires, which are seasonal. Many are likely to be on grassland, woodland or savannah in poor farming communities.  “Fires are very important landscape management tools and are used to clear land for planting crops,” says Lauren Williams, a specialist in Central and West African forests at the World Resources Institute.

Modernize or Die: Bio-Engineered Food

China is betting that CRISP technology*can transform the country’s food supply.  China also expanded its efforts beyond its borders in 2017, when the state-owned company ChemChina bought Switzerland-based Syngenta—one of the world’s four largest agribusinesses, which has a large R&D team working with CRISPR—for $43 billion. That was the most China has ever spent on acquiring a foreign company, and it created an intimate relationship between government, industry, and academia—a “sort of a ménage à trois” that ultimately could funnel intellectual property from university labs into the company, says plant geneticist Zachary Lippman of Cold Spring Harbor Laboratory in New York.

Chinese leaders “want to strategically invest in genome editing, and [by that] I mean, catch up,” says Zhang Bei, who heads a team of 50 scientists at the Syngenta Beijing Innovation Center…China may one day need CRISPR-modified plants to provide enough food for its massive population….    China needs to resolve how it will regulate CRISPR-engineered crops—a divisive issue in many countries. In a 2018 decision that rocked big agriculture, a European court ruled that such crops are genetically modified organisms (GMOs) that need strict regulation. In contrast, the U.S. Department of Agriculture (USDA) exempts genome-edited plants from regulations covering GMOs as long as they were produced not by transferring DNA from other species, but by inducing mutations that could have occurred naturally or through conventional breeding.  Chinese consumers are wary of GM food. The country strictly limits the import of GM crops, and the only GM food it grows are papayas for domestic consumption. But for CRISPR, many plant researchers around assume China will follow in the United States’s footsteps…

For Corteva, Syngenta, and the other two big ag companies—BASF and Bayer (which acquired Monsanto last year)—the long game is to use CRISPR to develop better versions of their serious moneymakers, the “elite” varieties of a wide range of crops that have big commercial markets. They sell dozens of kinds of elite corn seeds—for example, inbred strains that consistently have high yields or reliable resistance to herbicides. Creating the genetic purity needed for an elite variety typically takes traditional breeding of many generations of plants, and CRISPR is seen as the cleanest way to improve them quickly. The earlier methods of engineering a plant can lead to unwanted genomic changes that must be laboriously culled…

Syngenta sees CRISPR-modified corn as a big opportunity in China, which grows more hectares of corn than any other crop. Yields per hectare are only 60% of those in the United States because corn ear worms often weaken Chinese crops. A fungus thrives in the weakened plants, producing a toxin that makes the resultant ears unfit for animal feed. As a result, China must import a great deal of corn. (According to USDA, 82% of U.S.-grown corn has been engineered to have a bacterial gene that makes it resistant to ear worms.)…“Syngenta is putting a lot of emphasis to grow in China to become the leading seed company. The China market as a whole, if it modernizes as the U.S. has modernized, can be as big as the U.S. market.”

Jon Cohen, To feed its 1.4 billion, China bets big on genome editing of crops, Science Magazine, Aug. 2, 2019

* Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. Several approaches to genome editing have been developed. A recent one is known as CRISPR-Cas9.

The Rolls Royce Nuclear Reactor

Small modular nuclear  reactors (SMRs) are relatively small and flexible: they have a power capacity of up to 300 MW(e) and their output can fluctuate in line with demand. This makes them particularly attractive for remote regions with less developed grids, but also for use as a complement to renewables and for non-electric applications of nuclear power. SMRs can be manufactured and then shipped and installed on site, so they are expected to be more affordable to build.

The Rolls Royce SMR is small enough to be transported by truck.

Globally, there are about 50 SMR designs and concepts at different stages of development. Three SMR plants are in advanced stages of construction or commissioning in Argentina, China and Russia, which are all scheduled to start operation between 2019 and 2022…Some SMR designs have features that could reduce the tasks associated with spent fuel management. Power plants based on these designs require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants, and some are even designed to operate for up to 30 years without refuelling. Nevertheless, even in such cases, there will be some spent fuel left, which will have to be properly managed.

Who Owns Your Voice? Grabbing Biometric Data

Increasingly sophisticated technology that detects nuances in sound inaudible to humans is capturing clues about people’s likely locations, medical conditions and even physical features.Law-enforcement agencies are turning to those clues from the human voice to help sketch the faces of suspects. Banks are using them to catch scammers trying to imitate their customers on the phone, and doctors are using such data to detect the onset of dementia or depression.  That has… raised fresh privacy concerns, as consumers’ biometric data is harnessed in novel ways.

“People have known that voice carries information for centuries,” said Rita Singh, a voice and machine-learning researcher at Carnegie Mellon University who receives funding from the Department of Homeland Security…Ms. Singh measures dozens of voice-quality features—such as raspiness or tremor—that relate to the inside of a person’s vocal tract and how an individual voice is produced. She detects so-called microvolumes of air that help create the sound waves that make up the human voice. The way they resonate in the vocal tract, along with other voice characteristics, provides clues on a person’s skull structure, height, weight and physical surroundings, she said.

Nuance’s voice-biometric and recognition software is designed to detect the gender, age and linguistic background of callers and whether a voice is synthetic or recorded. It helped one bank determine that a single person was responsible for tens of millions of dollars of theft, or 18% of the fraud the firm encountered in a year, said Brett Beranek, general manager of Nuance’s security and biometrics business.

Audio data from customer-service calls is also combined with information on how consumers typically interact with mobile apps and devices, said Howard Edelstein, chairman of behavioral biometric company Biocatch. The company can detect the cadence and pressure of swipes and taps on a smartphone.  How a person holds a smartphone gives clues about their age, for example, allowing a financial firm to compare the age of the normal account user to the age of the caller…

If such data collected by a company were improperly sold or hacked, some fear recovering from identity theft could be even harder because physical features are innate and irreplaceable.

Where to Go? 1 Million Tons Radioactive Water at Fukushima

In August 2019, Tepco projected that storage of radioactive water at the Fukushima nuclear plant would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate.  According to Tepco, the Fukushima No. 1 plant had 960 massive tanks containing 1.15 million tons of treated water as of July 18, 2019. Water that has touched the highly radioactive melted fuel debris has been cleaned up through water treatment machines and is stored in the tanks, but the high-tech treatment machines are able to remove most radionuclides except tritium. The plant currently sees an increase of contaminated water by 170 tons a day, Tepco says.

Releasing tritium-tainted water into the sea in a controlled manner is common practice at nuclear power plants around the world, and it was generally considered the most viable option as it could be done quickly and would cost the least.  The head of the Nuclear Regulation Authority, Toyoshi Fuketa, has long said that releasing the treated water into the sea is the most reasonable option, but people in Fukushima, especially fishermen, fear it will damage the region’s reputation.

Addressing those concerns, the government panel, launched in November 2016, has been looking for the best option in terms of guarding against reputational damage. Injecting it into the ground, discharging it as steam or hydrogen, or solidification followed by underground burial have all been on the table. Under the current plan, Tepco is set to increase the tank space to store 1.37 million tons of water a total, but estimates show that will only last until summer 2022.  But the more space it creates, the bigger the decommissioning headache becomes.
