European regulations and impacts on microplastics

EU Regulation 2023/2055 represents a crucial breakthrough in the fight against microplastic pollution. This legislation, the result of extensive studies conducted by the European Chemicals Agency (ECHA), introduces restrictions on the use of microplastics intentionally added to various products. Among the categories most affected by the new regulations are artificial sports surfaces, such as synthetic turf fields, which traditionally use polymeric infill materials to ensure optimal performance.

The implications of this legislation are significant. Each year, an estimated 42,000 tons of intentionally added microplastics are released into the environment in the European Union, a large portion of which comes from the very infill materials used in sports fields. This type of pollution has devastating effects on the ecosystem, as microplastics, which are resistant to degradation, accumulate in soil, water and even the food chain, putting biodiversity and human health at risk.

The eight-year transition period provided by the legislation gives the sports industry an opportunity to adapt and adopt alternative materials. It is in this context that cork for filling emerges as an ideal solution. As an all-natural and biodegradable material, cork eliminates the problem of microplastics at the root, offering a concrete and sustainable response to new regulatory requirements.
