"It does work to set limits and implement them. It's potential to search out different options and if one producer could make packaging with out PFAS, then it must be potential for everyone to do it."

PFAS chemical substances are in lots of merchandise: nonstick cookware, infection-resistant surgical robes and drapes, cell telephones, semiconductors, industrial plane and low-emission automobiles.
