Researchers recycle fluoride from PFAS chemicals effectively

Researchers at the University of Oxford and Colorado State University have developed a new method to recycle fluorine from harmful PFAS chemicals. These chemicals, known as "forever chemicals," persist in the environment and can be found in everyday products like non-stick cookware and food packaging. The team's innovative approach uses potassium phosphate salts and ball-milling techniques to break down PFAS compounds. This process not only destroys these hard-to-remove chemicals but also recovers fluorine for use in industrial processes, supporting a circular economy for fluorine. The study reveals that their method can effectively target various PFAS classes, enabling the reuse of fluorine in making important chemicals, including medications and agricultural products. The research aims to tackle the growing environmental issue posed by PFAS contamination in drinking water and soil. Professor Véronique Gouverneur highlighted the significance of fluorine recovery, especially as natural resources are dwindling. The new method could change perceptions of PFAS and lead to better waste management solutions.
