Microplastics

At home and abroad, the UK is taking action to develop our understanding of the microplastic problem and to prevent and reduce microplastic pollution. Microplastics are used in a range of applications and are produced from the degradation of plastic products.

Plastic pellets are the feedstock for the production of plastic products, and can be lost throughout the supply chain. To tackle this issue, we have supported the development of a Publicly Available Specification by the British Standards Institution (PAS 510:2021), which sets out the steps companies should take to reduce the loss of plastic pellets across their operations.

Technical experts from the Centre for Environment, Fisheries and Aquaculture Science (Cefas) have also been leading the Oslo and Paris Convention (OSPAR) Convention to develop a new indicator for microlitter (including microplastics) in seafloor sediments. This will help us to track progress in reducing plastics in the environment at a regional scale. The UK also contributes to the OSPAR Microplastic Expert Group, which is examining ways that we can better detect and quantify microplastics in samples taken for research.

Finally, in negotiations to establish a new international treaty on plastic pollution, the UK has called for binding provisions to reduce and prevent microplastic pollution from all sources. In particular, the UK has called for specific provisions to prevent and eliminate emissions and releases of plastic pellets, flakes and powder across the whole supply chain.
