374Water Inc.

374Water Inc. is a cleantech and environmental services company that develops supercritical water oxidation (SCWO) technology to destroy organic waste streams. The company offers its proprietary AirSCWO technology, which is designed to destroy and mineralize a broad spectrum of non-hazardous and hazardous organic wastes. This process produces safe dischargeable water streams, safe mineral effluent, safe vent gas, and recoverable heat energy. The AirSCWO system aims to eliminate recalcitrant organic wastes without creating waste byproducts and to simplify existing waste processing and disposal practices. This technology is designed to convert solid and liquid wastes, such as sewage sludge, biosolids, food waste, and hazardous and non-hazardous waste, including 'forever chemicals' (per-and polyfluoroalkyl substances or PFAS), into inert and recoverable resources like water, minerals, and heat energy. 374Water operates across three main market sectors: industrial, municipal, and federal. In the 2025 fiscal year, the company established its Waste Destruction Services (WDS) hub at the City of Orlando's Iron Bridge Water Reclamation Facility. It also deployed a commercial AirSCWO system to Detroit, MI, for a six-week Department of Defense (DoD) Destruction Demonstration of six PFAS-impacted waste streams. Additionally, 374Water deployed its mobile AirSCWO lab to Peterson Space Force Base in Colorado and tested waste streams from various clients, including major oil and gas companies, multi-national chemical and pharmaceutical companies, the United States DoD and defense contractors, and resource recovery companies, at its laboratory in the Research Triangle, North Carolina.
