TreaTech’s Innovative Waste-to-Energy Process Also Destroys Recalcitrant PFAS
- TreaTech’s innovative catalytic hydrothermal gasification (cHTG) process converts waste streams like agricultural wastes, chemical wastes, industrial food waste streams, and biosolids into renewable gas and clean water.
- The cHTG process brings the waste into supercritical water conditions (400 °C, 250 bar) and passes the waste through a catalytic reactor that converts organic carbon molecules to a methane-rich gas.
- Recent testing on a model feedstock amended with several types of per- and polyfluoroalkyl substances (PFAS) confirmed the following: PFOS, PFOA, and PFBS were destroyed >99.8% each under unoptimized conditions.
- Complete destruction of these PFAS was confirmed via measurement of speciated PFAS, fluoride, and adsorbable organofluorine. A full fluorine mass balance was achieved.
- The cHTG process shows excellent promise at destroying PFAS in PFAS-rich wastes, as well as wastes that incidentally contain PFAS.
- TreaTech continues to optimize the cHTG process to achieve PFAS destruction in a variety of wastes.
We are now inviting industrial partners to work with us and test our technology on real PFAS-containing waste streams.
