This briefing note describes the various pathways PFAS can take to accumulate in air, soil and plants. It identifies the main contributors of PFAS in waste water and how PFAS can end up in biosolids. We demonstrate how only a full PFAS ban can allow for the inclusion of biosolids (also known as sewage sludge) in the circular economy through agricultural application and incineration while encompassing the nutrient recycling potential.
