According to 374Water, AirSCWO aims to create a new category of critical waste destruction infrastructure by destroying contaminants rather than storing or relocating them, while also reducing waste volume, lowering disposal costs, recovering resources, and producing safe, dischargeable water, mineral effluent, vent gas, and recoverable heat energy.
374Water (NASDAQ:SCWO) reported completion of Phase 3 of its mobile AirSCWO deployment at the St. Cloud, Minnesota NEWRF facility and the start of Phase 4 under a $600,000 Waste Destruction Services contract with the City of St. Cloud and partner Barr Engineering.
From June 1 to July 31, Phases 1–3 successfully processed three distinct biosolids feedstocks—Class B biosolids, Class A biosolids, and pre-digestion sludge—under varied operating conditions, with no operational issues and preliminary PFAS destruction results described as impressive. The campaign supports the State of Minnesota’s evaluation of AirSCWO for permanent PFAS destruction, aided by LCCMR and ENRTF funding, while Phase 4 focuses on Class B biosolids blended with PFAS-laden spent granular activated carbon from Cottage Grove.
According to 374Water, the mobile AirSCWO system could generate an estimated $500,000–$1.5 million in annual revenue per unit, and a successful pilot may support a broader state assessment that the company believes could lead to multiple millions of dollars in recurring revenue opportunities.
374Water (NASDAQ:SCWO) reported second quarter 2026 revenue of $2.26 million, up about 280% from roughly $0.6 million in Q2 2025, mainly from completing project milestones including the Orange County Sanitation District Factory Acceptance Test. First-half 2026 revenue was $2.8 million versus $1.1 million a year earlier.
Q2 2026 gross profit was $1.98 million with an 87% gross margin, compared with a gross deficit of about $0.3 million and a negative margin in Q2 2025. Operating expenses fell to $3.6 million from $4.3 million, reducing operating loss to $1.6 million and net loss to $2.7 million ($0.15/share) from $4.6 million ($0.32/share). Cash used in operations for the first half improved to $(2.3) million from $(7.6) million, with cash and equivalents of $1.8 million at June 30, 2026.
According to 374Water, it cut annualized operating costs by about $3.2 million, advanced its Waste Destruction Services strategy, secured a long-term Orlando WDS facility agreement, progressed municipal deployments in California, Minnesota, and Kansas, and reported >99.9% PFAS destruction in U.S. Department of Defense testing of its AirSCWO technology.
374Water (NASDAQ: SCWO) announced that the U.S. Department of Defense Defense Innovation Unit issued a Success Memo to partner Arcadis, validating the economic and technical viability of 374Water’s AirSCWO PFAS destruction technology and formally closing the DIU/ESTCP prototype phase.
The Success Memo, under the federal Other Transaction Authority framework, enables federal agencies to move directly to follow-on production awards and procure AirSCWO as a commercial product. This aligns with 374Water’s Orlando Waste Destruction Services hub, which serves PFAS, biosolids, industrial sludges and other difficult waste streams and targets $3–$5 million in annual recurring revenue at initial scale following expansion to 88,000 gallons of onsite storage and upgraded AirSCWO throughput capacity.
374Water (NASDAQ:SCWO) reported preliminary second quarter 2026 revenue of more than $2.2 million, up from $0.6 million in 2025, with first-half 2026 revenue exceeding $2.8 million versus $1.1 million a year earlier. According to 374Water, growth was driven largely by approximately $2.0 million recognized following a successful Factory Acceptance Test (FAT) for the Orange County Sanitation District (OC San) AirSCWO system.
The completed OC San FAT positions the company to invoice about $2.6 million in remaining contract billings and recognize roughly $1.1 million in additional revenue as milestones are met. 374Water also received a $4.8 million order from Olathe, KS, advanced a $600,000 St. Cloud, MN pilot to Phase III, and expanded its Orlando Waste Destruction Services hub to approximately 88,000 gallons of storage capacity. The company entered a strategic MOU with Arcadis focused on federal PFAS destruction opportunities and appointed Charles “Chuck” Weiser as Chief Financial Officer and Richard “Rick” Davis to the Board.
374Water (NASDAQ:SCWO) is highlighting its Air Supercritical Water Oxidation (AirSCWO™) technology, which is designed to permanently destroy organic contaminants such as PFAS “forever chemicals,” pathogens including Cyclospora, pharmaceuticals, biosolids, and industrial waste at the molecular level to support cleaner water and wastewater reuse.
According to 374Water, commercialization efforts include commercial operations at Orlando’s Iron Bridge Water Reclamation Facility, expansion of its Waste Destruction as a Service model, deployments in Olathe (KS), St. Cloud (MN) and Orange County Sanitation District (CA), and Department of Defense-sponsored validation showing >99.9% PFAS destruction across multiple waste streams.
374Water (NASDAQ:SCWO) reported completion of Phase 2 of its mobile AirSCWO deployment at the City of St. Cloud, Minnesota, under a $600,000 Waste Destruction Services contract, and the start of Phase 3. The State of Minnesota is using this campaign, supported by LCCMR and ENRTF, to evaluate AirSCWO for permanent PFAS destruction.
Phase 2 processed Class A biosolids from a Lystek thermal hydrolysis process, including a strong run at up to 12% solids, with all planned sampling completed and performance described as consistent with previous AirSCWO campaigns. Phase 3 has begun on pre-anaerobic digestion sludge, a waste stream previously processed by the company with 97% solids reduction and up to 99.99%+ PFAS reduction in earlier campaigns. According to 374Water, each mobile AirSCWO unit is estimated to have the potential to generate $500,000–$1.5 million in annual revenue, depending on deployment cadence, waste composition, and contract structure, and the St. Cloud project is intended to help build a scalable, recurring mobile services business.
374Water (NASDAQ:SCWO) announced that a U.S. Army Engineer Research and Development Center (ERDC) technical report independently validated its AirSCWO™ technology for destroying PFAS in aqueous film-forming foam (AFFF). The AirSCWO 6 system achieved a total PFAS destruction and removal efficiency of 99.9993% across 42 PFAS compounds, with individual compounds between 99.994% and 100%.
