This Practice Note covers EU legislative measures established to reduce the presence and impact of microplastics in the environment, including measures to reduce plastic pollution, measures to restrict the use of intentionally added microplastics in products, and measures to reduce unintentional microplastic releases. What are microplastics? Microplastics are small pieces of plastic, typically with a diameter of less than 5mm. They may be intentionally added to products in order to accomplish a certain function (eg in cosmetic products, fertilisers, pesticides, on synthetic sports surfaces, or in medical devices). They are also—and most commonly—generated through the fragmentation and degradation of larger pieces of plastic litter exposed to sun or water in the environment and through the wear and tear of plastic or plastic-containing products (eg through abrasion of tyres or washing of synthetic textiles). What are the risks posed by microplastics? As of 2018, when the Commission published the EU Plastics Strategy, it was estimated that between 30,000 and 75,000 tonnes of microplastics were released into the environment in the EU each year. This presence of microplastics
