Over 150 organizations back call to ban oxo-degradable plastic packaging

What are oxo-degradable plastics?

Oxo-degradable plastics are conventional polymers (e.g. LDPE) to which chemicals are added to accelerate the oxidation and fragmentation of the material under the action of UV light and/or heat, and oxygen. Oxo-degradable plastics should not be confused with compostable plastics that comply with international standards and can be safely biodegraded through (industrial) composting.

Oxo-degradable plastic packaging, including single-use bags, are often marketed as a solution to plastic pollution, with claims that such plastics degrade into harmless residues within a period ranging from a few months to several years. However, as outlined in a new statement by the Ellen MacArthur Foundation’s New Plastics Economy initiative, significant evidence indicates that oxo-degradable plastics do not degrade into harmless residues, but instead fragment into tiny pieces of plastic and contribute to microplastic pollution, posing a risk to the ocean and other ecosystems, potentially for decades to come.

Why ban oxo-degradable plastic packaging?

Plastic Pollution Coalition joins over 150 organizations worldwide endorsing the new statement that proposes banning oxo-degradable plastic packaging worldwide. 

“The available evidence overwhelmingly suggests oxo-degradable plastics do not achieve what their producers claim and instead contribute to microplastic pollution. In addition, these materials are not suited for effective long-term reuse, recycling at scale or composting, meaning they cannot be part of a circular economy," said Rob Opsomer, Lead for Systemic Initiatives at the Ellen MacArthur Foundation.

“Using oxo-degradable additives is not a solution for litter. Their use in waste management systems will likely cause negative outcomes for the environment and communities,” said Erin Simon, Director of Sustainability Research and Development, World Wildlife Fund. “When public policy supports the cascading use of materials – systems where materials get reused over and over, this strengthens economies and drives the development of smarter materials management systems. This leads to wins for both the environment and society.”

As a result of the significant body of evidence raising concerns about the potential negative impacts of plastic fragments from oxo-degradable plastics, an increasing number of companies and governments have started to take action to restrict their use, in particular in Europe. For example, in the UK retailers such as Tesco and the Co-operative stopped the use of oxo-degradable plastics in their carrier bags. France banned the use of oxo-degradable plastics altogether in 2015.

However, oxo-degradable plastics are still produced in many European countries, including the UK, and marketed across the world as safely biodegradable. Several countries in the Middle-East and Africa, including the United Arab Emirates, Saudi Arabia, areas of Pakistan, Yemen, Ivory Coast, South Africa, Ghana and Togo, are still promoting the use of oxo-degradable plastics or have even made their use mandatory.

To create a plastics system that works, the Ellen MacArthur Foundation’s New Plastics Economy initiative, together with the signing organizations, supports innovation that designs out waste and pollution, and keeps products and materials in high-value use in line with the principles of a circular economy.
