Importantly, our AirSCWO system is designed to eliminate recalcitrant organic wastes without creating waste byproducts, as well as to simplify existing, complex waste processing and disposal practices. Our AirSCWO technology is designed to effectively convert solid and liquid wastes such as sewage sludge, biosolids, food waste, hazardous and non-hazardous waste, including forever chemicals’ (e.g., per-and polyfluoroalkyl substances or PFAS ) into inert and recoverable resources including water, minerals, and heat energy. 374Water made significant commercial and technological progress throughout the 2025 fiscal year. We continue to make technological breakthroughs in processing solids and slurries, as well as liquid waste streams across three main market sectors industrial, municipal, and federal.
