Defra
In its response in April 2021 to its Call for evidence for Standards for Biodegradable, Compostable and Bio-based Plastics, the UK Dept. of the Environment (DEFRA) said “We are minded to introduce a ban on oxo-degradable plastics, subject to further evidence and a public consultation.”
They now have the evidence from the 4-year Oxomar study sponsored by the French government proving that oxo-biodegradable plastics do biodegrade, even in the marine environment, much more efficiently than conventional plastics. They are also aware that the European Chemicals Agency, after ten months’ study and hundreds of pages of scientific evidence, was not convinced that they create microplastics.
