We'll also have to learn how to handle alternatives to many other PFAS-containing items, such as firefighting foams. Non-PFAS products perform differently to PFAS-containing aqueous film-forming foam (AFFF) when fighting gas and oil fires, but non-PFAS foams are already used around the world.
Shari Franjevic is the programme manager for GreenScreen, which certifies products as free of PFAS and other chemicals. "In countries where PFAS-free products are allowed, for use at airports, for example, the products are being purchased and users are satisfied with the performance, e.g. London Heathrow," Ms Franjevic says.
"We understand that while PFAS-free products perform differently than PFAS-containing products, they are capable of meeting the performance needs in most, if not all, situations."
