The PFAS dilemma: Why replacing and phasing out these substances is becoming a project for generations to come

Headlines about PFAS are becoming increasingly frequent: this group of substances, which went unnoticed for a long time, is everywhere – even in food and in the bodies of humans and animals – and it is not simply going to disappear. Whilst environmental and consumer protection campaigners are pushing for a swift end to exposure, industry is searching for alternatives for key technologies. However, the path to a PFAS-free future is a generational project that will challenge business, research and society for decades to come. In an interview with SATW, Manfred Heuberger (Empa), Martin Scheringer (ETH Zurich) and Dominique Werner (Scienceindustries) explain what the biggest challenges are when dealing with PFAS.
