20.3 : Reactive Bimetallic-Carbon Media For Destruction Of PFAS-Containing Aqueous Fire Fighting Foam Stockpiles
Per- and polyfluorinated substances (PFAS) are a group of >5,000 chemicals used across wide ranging applications from water-repellent surfaces to Aqueous Film-Forming Foams (AFFF). These “forever chemicals” are known to cause critical health conditions and are not degraded by normal hazardous waste treatment methods. The Air Force has spent $546M on PFAS actions to date and is believed to have 2 million gallons of decommissioned PFAS-containing AFFF awaiting proper disposal. Currently used incineration methods are halting around the US due to concerns of ineffectiveness. AxNano LLC has developed RemRx™ ZVI, a proprietary bimetallic-carbon composite material engineered to trap and degrade PFAS compounds through effective reductive chemistry. In collaboration with Purdue University, the bimetallic-carbon composite has shown promising efficacy for breaking down a wide range of PFAS compounds.
