Rice University researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS) Traditional methods of PFAS disposal are costly, energy-intensive and often generate secondary pollutants.

Process employs flash joule heating (FJH) to tackle these challenges.

Process breaks down strong carbon-fluorine bonds in PFAS , converting them into inert, nontoxic fluoride salts.

Simultaneously, the GAC is upcycled into graphene, a valuable material used in industries ranging from electronics to construction.
