AVANTech's Advanced PFAS Polymerization (AP2) Technology Development

By Michael Reed and Jaclyn Looper

AVANTech completed bench-scale testing of a variety of solidification technologies to allow for the safe and efficient disposal of highly concentrated PFAS waste. The testing of AVANTech’s Advanced PFAS Polymerization (AP2) technology primarily focused on epoxy polymer solidification of PFAS-contaminated Ion Exchange resins. Similar technologies have previously been successfully developed and employed for nuclear waste applications. Parameters such as percent resin loading, moisture levels, additives, and encapsulation methods were evaluated to determine the best formulation for immobilization of PFAS-contaminated resin. This formulation was found to be both effective at preventing leaching from the monolith and extremely physically stable. The resulting solidification technology is ready for the next step in development – on-site field demonstrations.
