Ball milling destroyed diverse PFAS classes while recovering reusable fluoride
Potassium phosphate salts and solvent-free mechanochemical milling mineralized several PFAS classes, including PTFE, PVDF, PFOA and PFOS. The process recovered fluorine as KF and K2PO3F for reuse and also treated consumer materials and PFAS-loaded activated carbon.

Record details
- Problem or result
- Many PFAS remediation methods transfer contamination, consume large amounts of energy or work on only a narrow subset of persistent fluorochemicals.

Why it matters
The method couples broad fluorochemical destruction to recovery of useful fluorine rather than merely concentrating or transferring the waste.
Limits
The work is laboratory scale, and energy demand, reactor wear, lifecycle emissions, cost, heterogeneous waste handling and residue management need independent scale-up testing. A patent has been filed, and the result does not mean the global PFAS problem is solved.
