White Paper: Microplastics in Compost – The Environmental Hazards Inherent in the Composting of Plastic-Coated Paper Products

Plastic-coated paper products collected by many composting programs produce both macro and micro-fragments of non-biodegradable plastic, which then contaminate finished compost and the soils where this compost is applied. These fragments may then be transported by wind and water into nearby ecosystems, and ultimately into marine ecosystems, adding to the growing and serious problem of plastic pollution.
