US appeals court kills ban on plastic containers contaminated with PFAS

Sat 30 Mar 2024 11.00 GMT

A federal appeals court in the US has killed a ban on plastic containers contaminated with highly toxic PFAS “forever chemicals” found to leach at alarming levels into food, cosmetics, household cleaners, pesticides and other products across the economy.

Houston-based Inhance manufactures an estimated 200m containers annually with a process that creates, among other chemicals, PFOA, a toxic PFAS compound. The Environmental Protection Agency (EPA) in December prohibited Inhance from using the manufacturing process.

But the conservative fifth circuit court of appeals court overturned the ban. The judges did not deny the containers’ health risks, but said the EPA could not regulate the buckets under the statute it used.

The rule requires companies to alert the EPA if a new industrial process creates hazardous chemicals. Inhance has produced the containers for decades and argued that its process is not new, so it is not subject to the regulations. The EPA argued that it only became aware that Inhance’s process created PFOA in 2020, so it could be regulated as a new use, but the court disagreed.

“The court did not dispute EPA’s underlying decision that this is a danger to human health, what they did was say it’s not a new use, which I think is wrong … but this case isn’t over by any stretch,” said Kyla Bennett, a former EPA official now with the Public Employees for Environmental Responsibility (Peer) non-profit, which has intervened in legal proceedings.

PFAS are a class of about 15,000 compounds used to make products resistant to water, stains and heat. They are known as “forever chemicals” because they do not naturally break down, and they have been linked to cancer, high cholesterol, liver disease, kidney disease, fetal complications and other serious health problems.

Boom in mining for renewable energy minerals threatens Africa’s great apes

Wed 3 Apr 2024 19.00 BST



Up to a third of Africa’s great apes are threatened by a boom in mining projects for minerals required for the renewable energy transition, new research shows.

An estimated 180,000 gorillas, bonobos and chimpanzees are at risk due to an increase in demand for critical minerals such as copper, lithium, nickel and cobalt, a study has found. Many of those minerals are required for clean energy technologies such as wind turbines and electric cars. Researchers say the boom in demand is driving destruction of tropical rainforests which are critical habitats for Africa’s great apes.

“Africa is experiencing an unprecedented mining boom threatening wildlife populations and whole ecosystems,” researchers wrote in the paper, published in Science Advances. Africa is home to an estimated 30% of the world’s mineral resources, and substantial production increases in renewable energy are expected to drive up demand.

Mining harms apes through habitat loss, pollution and disease. It can also make habitats more accessible to hunters and farmers, as roads are carved into forest. More than two-thirds of primate species are already threatened with extinction.

“A shift away from fossil fuels is good for the climate but must be done in a way that does not jeopardise biodiversity,” said lead researcher Dr Jessica Junker from the non-profit conservation organisation Re:wild. “In its current iteration it may even be going against the very environmental goals we’re aiming for … It is crucial for everyone to adopt a mindset of reduced consumption.”
