(the “Company”, “374Water”, “We”, or “Our”) is a global industrial technology and services company providing innovative solutions addressing global organic waste destruction/treatment and waste management issues within the Municipal, Federal, and Industrial markets. 374Water offers our proprietary AirSCWO system, which is designed to efficiently destroy and mineralize a broad spectrum of non-hazardous and hazardous organic wastes producing safe dischargeable water streams, safe mineral effluent, safe vent gas, and recoverable heat energy. Importantly, our AirSCWO system eliminates recalcitrant organic wastes without creating waste byproducts. Our AirSCWO system effectively converts solid and liquid wastes such as sewage sludge, biosolids, food waste, hazardous and non-hazardous waste, and forever chemicals (e.g., “per-and polyfluoroalkyl substances” or “PFAS”) into recoverable resources including water, minerals, and heat energy, by focusing on waste as a valuable resource.
