Systems, methods, and devices for destruction of per- and polyfluoroalkyl substances (pfas) and for reactivating spent activated carbon

Patent published on the 2025-03-06 in WO under Ref WO2025049798 by 6K INC [US] (Lee Judith [us], Redjdal Makhlouf [us], Majcher Jared [us], Kaiser Ashley [us])

Abstract: Embodiments disclosed herein relate to a systems, methods, and apparatus for the destruction of per- and polyfluoroalkyl substances (PFAS). These embodiments may be applied to spent activated carbon or biosolids containing PFAS. Embodiments disclosed herein involve destruction of PFAS using a microwave generated plasma, including propagating microwaves through a microwave plasma apparatus, the microwaves generated using a microwave generator to generate a microwave plasma; introducing the PFAS i[...]

Fluid resistant treatment and garments treated therewith

Patent published on the 2025-03-06 in WO under Ref WO2025049447 by DIIANNI WILLIAM J [US] (Arangdad Kiarash [us], Diianni William J [us])

Abstract: In one aspect, fabric materials are disclosed that have been treated with a fluid resistant treatment containing a water resistant composition and an oil resistant composition. The fluid resistant treatment may be substantially fluorocarbon free. Fire service garments can be made from the fabric materials that provide resistance to water and/or oil.[...]

Our summary: Fabric materials treated with a fluid resistant treatment containing water and oil resistant compositions, fire service garments made from these materials providing resistance to water and oil.

Interesting read! But arent there safer alternatives to PFAS? We should be focusing more on those, dont you think?

Interesting read, but arent some PFAS beneficial in certain industries? We cant just outright ban them, can we?
