Perfluoroalkyl and polyfluoroalkyl substances (PFAS), commonly referred to as forever chemicals, have been linked to a number of health concerns. In April 2024, the U.S. Environmental Protection Agency labeled a specific PFAS known as perfluorooctane sulfonic acid (PFOS) and its salts and isomers as hazardous chemicals.

Scientists from the UK’s University of Oxford and Colorado State University have developed a novel method for both destroying PFAS and reusing some of their elements in new products. Their method, published in the journal Nature, involves reacting PFAS with potassium phosphate salts and then grinding the PFAS and salts together using ball bearings to break the carbon-fluorine bonds. This process facilitates the reuse of the fluorine content in the manufacturing of medicines and other products
