In advance of the Global Plastics Treaty Negotiations, which are set to resume in Paris at the end of this month, Greenpeace is releasing a new report cataloging the many ways in which recycled plastics are toxic. We’d already reported on the toxicity of recycled plastics where we interviewed Gaia about the toxic effects of recycled plastics. And we know only about 5% of plastics in America are ever recycled.
The process of recycling plastic material is poorly regulated, if it happens at all. Today only 9% of plastic is recycled worldwide, according to the UN, and that which is putting people and planet at risk. Recycled plastics usually contain higher levels of chemicals like toxic flame retardants, benzene and other carcinogens, environmental pollutants like brominated and chlorinated dioxins, and numerous endocrine disruptors that can cause changes to the body’s natural hormone levels.
A new report from Greenpeace USA (get the full PDF report here) provides a catalog of peer-reviewed research and international studies concluding that recycling actually increases the toxicity of plastics. It highlights the threat that recycled plastics pose to the health of consumers, frontline communities, and workers in the recycling sector.
The report outlines that plastics contain more than 13,000 chemicals, with more than 3,200 of them known to be hazardous to human health. Recycled plastics often contain higher levels of chemicals that can poison people and contaminate communities.
“The plastics industry—including fossil fuel, petrochemical, and consumer goods companies—continues to put forward plastic recycling as the solution to the plastic pollution crisis. But this report shows that the toxicity of plastic actually increases with recycling,” says Graham Forbes, Global Plastics Campaign Lead at Greenpeace USA. “Plastics have no place in a circular economy and it’s clear that the only real solution to ending plastic pollution is to massively reduce plastic production.”
Greenpeace at the Paris meetings
At the Paris meetings, formally known as the second Intergovernmental Negotiating Committee (INC) meeting for the Global Plastics Treaty, the Greenpeace global network is advocating for an ambitious, legally binding agreement that accelerates a just transition away from a dependence on plastic materials and establishes global controls to regulate toxic chemicals in plastic.
Over 100 scientists and civil society groups issued a letter urging the United Nations to prevent the fossil fuel industry and plastics industry from undermining the negotiations. Jason Momoa, Jane Fonda, and Alec Baldwin and other celebrities call on the Biden Administration to support a legally binding treaty that caps plastic production.
Plastic production, disposal, and incineration facilities are most often located in low-income, marginalized communities across the world, which suffer from higher rates of cancer, lung disease and adverse birth outcomes associated with their exposure to the toxic chemicals. The Treaty should generate opportunities for workers to leave polluting and toxic industries for healthier jobs in a reuse-based economy.
Jo Banner of The Descendants Project, based in the Mississippi River region of Louisiana, said: “Plastics production is inconsistent with healthy, thriving communities, and this report shows that plastics recycling only perpetuates those harms. My region is now known as ‘Cancer Alley’ for the extreme risks of cancer and death due to pollution from plastic producing industries. We are calling on world leaders to negotiate a global plastics treaty that ends plastic production, protects communities like ours and supports a just transition for workers across the plastics supply chain.”
The report highlights three “poisonous pathways” for recycled plastic material to accumulate toxic chemicals:
- Direct contamination from toxic chemicals in virgin plastic: When plastics are made with toxic chemicals and then recycled, the toxic chemicals can transfer into the recycled plastics.
- Leaching of toxic substances into plastic waste: Numerous studies show that plastics can absorb contaminants through direct contact and through the absorption of volatile compounds.When plastics are tainted by toxins in the waste stream and the environment and are then recycled, they produce recycled plastics that contain a stew of toxic chemicals. For example, plastic containers for pesticides, cleaning solvents, and other toxic chemicals that enter the recycling chain can result in contamination of recycled plastic.
- New toxic chemicals created by the recycling process: When plastics are heated in the recycling process, this can generate new toxic chemicals that make their way into the recycled plastics. For example, brominated dioxins are created when plastics containing brominated flame retardants are recycled, and a stabilizer used in plastic recycling can degrade to a highly toxic substance found in recycled plastics. Sorting challenges and the presence of certain packaging components in sorted materials can also lead to toxicity in recycled plastic. Studies have shown that benzene (a carcinogen) can be created by mechanical recycling of PET#1 plastic, even with very low rates of contamination by PVC#3 plastic, resulting in the cancer-causing chemical being found in recycled plastics.
At the Paris talks, Greenpeace is advocating for a seven-point plan that the Global Plastics Treaty should:
- Achieve immediate, significant reductions in plastic production, establishing a pathway to end virgin plastic production.
- Promote a shift to refill- and reuse-based economies, creating jobs and standards in new reuse industries and supporting established zero-waste practices.
- Support a just transition for workers across the plastics supply chain, prioritizing waste pickers who collect approximately 60% of all plastic that is collected for recycling globally.
- Promote non-combustion technologies for plastic waste stockpiles and waste disposal.
- Institute the “polluter pays” principle for plastic waste management and for addressing the health and environmental costs throughout the plastics life cycle.
- Significantly improve regulation, oversight, safety and worker protections for existing recycling facilities.
- Require transparency about chemicals in plastics and eliminate all toxic additives and chemicals used in the plastics life cycle.
