Managing PFAS Chemicals in Composting and Anaerobic Digestion

A lot of media attention is currently given to the issue of per- and polyfluoroalkyl substances (PFAS). The issues for composting and anaerobic digestion facilities are the presence of PFAS in finished compost or digestate products, and the presence of PFAS in facility storm water runoff. Composting or digestion facilities that take in biosolids, industrial residuals, and food scraps containing grease-resistant food packaging are receptors of PFAS chemicals. Read Part 1 of a new BioCycle series that explores ramifications of PFAS in recycled organics and process storm water — and technology options to treat the contamination.
