From the article, they are converting the granular activated carbon (GAC) that holds the PFAS into graphene. The PFAS itself is just converted “into inert, nontoxic fluoride salts.”
GAC is one way to filter PFAS out of drinking water, but then you’re left with a bunch of PFAS-laden media that you have to do something with. So this is one potential method of dealing with that.
