374Water Inc. (NASDAQ: SCWO)

374Water Inc. is a cleantech and environmental services company that develops supercritical water oxidation technology to destroy organic waste streams in municipal, federal, and industrial markets. Its proprietary AirSCWO system uses water above its critical point combined with air to mineralize hazardous and non hazardous wastes, producing clean water, mineral effluent, vent gas, and recoverable heat without creating waste byproducts. The technology targets sewage sludge, biosolids, food waste, spent filtration media, plastics, firefighting foam, landfill leachate, and persistent chemicals such as PFAS. The process operates at temperatures above 374°C and pressures above 221 bar, where water’s supercritical properties enable rapid oxidation of organic matter. The company’s vision is a world without waste and its mission is to destroy organic waste for a cleaner tomorrow. The AirSCWO platform can process both solid and liquid wastes, converting sewage sludge, spent activated carbon, and firefighting foam into reusable resources.

Revenue is generated from the sale of AirSCWO systems including mobile trailered units and modular units scalable from 6 to 10 tons per day, as well as from Waste Destruction Services where the company treats customer waste at partner sites. Additional income comes from laboratory testing and treatability studies, operations and maintenance support, and the provision of pre and post treatment equipment that conditions inlet streams and valorizes byproducts. Pre and post treatment solutions are offered as part of integrated packages, and the company also earns revenue from long term operations and maintenance agreements. The company has secured service agreements for ongoing waste destruction at its Orlando hub and has signed contracts for system placements at the Orange County Sanitation District, the city of Olathe, and other municipal and federal facilities. The company serves municipal water utilities, wastewater treatment plants, federal agencies such as the Department of Defense and Department of Energy, and industrial clients in oil and gas, chemicals, pharmaceuticals, and resource recovery. Waste Destruction Services are delivered through partner sites that provide infrastructure, allowing 374Water to scale without significant capital investment.

374Water occupies a niche within the waste destruction industry as one of the few providers of scalable supercritical water oxidation technology capable of achieving destruction efficiencies of 99.95% or higher across a broad spectrum of organic wastes. Competitors include other SCWO developers, plasma and electrochemical oxidation firms, and traditional methods such as anaerobic digestion, incineration, landfilling, and lime stabilization. The company’s advantages lie in its ability to destroy emerging contaminants like PFAS and pharmaceuticals, to recover usable heat and minerals, to eliminate secondary waste streams, and to offer modular continuously operating systems that reduce haulage and liability for customers. The system’s efficient energy recapture technology minimizes overall energy demand while maximizing reusable energy output, providing a cost advantage over thermally intensive alternatives. Market data shows the global municipal water and wastewater treatment market exceeds $347 billion annually, the U. S. federal waste management market is estimated at $15 billion, the global industrial waste management sector addressed by the company totals $144.5 billion, and there are more than 860 RCRA Part B permitted treatment storage and disposal facilities in the United States. The municipal wastewater sector is projected to grow at a compound annual growth rate of approximately 7.5%, driven by tightening regulations on contaminants such as PFAS and microplastics.

Specific customers named in the filing include the City of Orlando’s Iron Bridge Water Reclamation Facility, the Detroit MI site used for a Department of Defense PFAS destruction demonstration, Peterson Space Force Base in Colorado, the University of North Carolina at Chapel Hill Collaboratory, Clean Earth’s Detroit MI facility, Crystal Clean, the city of Olathe Kansas, and the Orange County Sanitation District in Fountain Valley California. The company also works with major oil and gas producers, multinational chemical and pharmaceutical companies, various defense contractors, and resource recovery firms seeking treatment of PFAS impacted waste streams. Additionally, 374Water has tested waste streams from several clients at its laboratory in Research Triangle North Carolina, further broadening its base of municipal federal and industrial partners. The Waste Destruction Services hub at Orlando’s Iron Bridge Water Reclamation Facility serves as a proving ground for technology improvements and a recurring revenue stream as customer waste volumes increase. While current operations are focused on North America, the company plans to expand its sales and marketing efforts into international markets in the future.
