“Researchers are investigating more cost-effective and practical destruction technologies that break down PFAS without the need for high heat or intense pressure.

Electrochemical and photochemical techniques have been used by scientists at the University of British Columbia to ‘zap’ PFOA that’s been trapped onto a reusable silica-based material. While another team at the University of California, Riverside, are using ‘deep UV’ – extremely low wavelengths (below 220nm) of ultraviolet light – to break PFAS down under ambient conditions without producing secondary waste”
