“Oxford Chemistry researchers have developed a method to destroy fluorine-containing PFAS (sometimes labeled ‘forever chemicals’) while recovering their fluorine content for future use. The results have been published in Nature.
PFAS—which stands for poly- and perfluoroalkylated substances—have been produced in large quantities for over 70 years. They are found in a wide variety of products, including textiles, food packaging, non-stick cookware, and medical devices. Their unique properties come from multiple carbon-fluorine chemical bonds, a particularly strong chemical motif that also explains their resistance to degradation.
This longevity has led to PFAS sometimes being referred to as ‘forever chemicals.’ Their persistence has resulted in widespread contamination around the world. Traces of PFAS have been found in drinking water and livestock, and have been associated with negative human health effects after chronic exposure.” …
