This KIMO Sweden report examines the release of plastic and rubber granules from artificial turf pitches and their movement into the surrounding environment. It describes the environmental impacts of granule pollution and considers measures that can reduce losses from facilities. The report also examines alternative infill materials and notes that protective measures can reduce, but not necessarily eliminate, granule leakage. It provides practical information for different stakeholders involved in artificial turf facilities, including owners, designers, maintenance teams and users. The resource supports municipal efforts to prevent microplastic pollution through better design, operation, procurement and consideration of alternative materials.
