摘要

The increasing presence of per- and polyfluoroalkyl substances (PFAS) in waste streams represents a significant and growing environmental concern. These persistent and stable substances enter biowaste through various pathways. Based on the analysis of different fractions of Austrian biowaste, the annual total PFAS load has been estimated at a minimum of 40 kg. The results highlight the need to explicitly consider PFAS during the treatment of organic waste, in order to prevent environmental contamination and the unintended reintroduction of these substances into material cycles. It becomes evident that conventional treatment processes are ineffective in removing PFAS and therefore cannot ensure complete pollutant elimination. Consequently, there is a need to develop innovative treatment strategies that can efficiently reduce PFAS levels. In addition, regulatory frameworks must be established to limit PFAS input into biogenic material streams. Alongside improved waste treatment, preventive measures at the product level and advanced research on the detection, assessment, and reduction of PFAS in biological processes are essential to achieve a long-term, sustainable, safe, and low-pollution circular economy.
