Reducing microplastic pollution from plastic pellet losses [EU Legislation in Progress]

Microplastics commonly refer to plastic particles below 5 mm in size. They can be grouped into two broad categories, primary and secondary microplastics, based on the formation processes involved.

Once dispersed in the environment, microplastic particles under 5 mm in size are extremely difficult to remove and very persistent. Today, they are present in the air, soil, freshwater, seas, oceans, plants and animals, and in several components of the human diet. Human exposure to microplastic particles is therefore widespread, raising concerns about potential health impacts.

On 16 October 2023, the European Commission proposed a regulation to tackle microplastic pollution resulting from losses of plastic pellets. The proposal would set requirements for best handling practices, mandatory certification and self-declaration, and provide for the development of a harmonised methodology to estimate losses.

The co-legislators reached a provisional deal on 9 April 2025. The Council formally adopted it on 22 September 2025. Parliament’s second-reading vote on the text is planned for the October II session.
