Imports of used PFAS into US scrutinized
News
15 Mar 2019 | Chemical & Engineering News
To meet demands for nonstick-pan coatings and fuel-cell components, Chemours depends on a fluorinated chemical called GenX. This compound helps building-block materials link together into tough, resistant plastics and industrial membranes. During the process of making these materials, GenX, an ammonium salt, ends up in water and hydrolyzes into…

DuPont has spread its pollution around the world. Now it wants to filter your contaminated drinking water
News
11 Dec 2018 | The Intercept
DuPont opened a factory in Saudi Arabia that will produce reverse osmosis water filters. The filters use ultra-thin membranes to remove water impurities, including PFAS — chemicals made and used by DuPont that have caused widespread water contamination around the world... “DuPont has learned the art of making money coming and going,” said Telsey. “They profited off the environmental contamination and now can profit on cleaning it up. It’s quite a feat.”...
