374Water (SCWO) has completed a four-phase, multi-feedstock mobile AirSCWO waste destruction campaign in St. Cloud, Minnesota under a $600,000 Waste Destruction Services contract with the City of St. Cloud and Barr Engineering.
From June through September, the field team processed four distinct PFAS‑laden feedstocks, including Class A and Class B biosolids, pre‑digestion sludge, and Class B biosolids blended with spent granular activated carbon, with no operational issues reported. The deployment emphasized detailed mass and energy balances and, with support from the University of St. Thomas, targeted detection of 96 PFAS species, more than twice those measured under EPA Method 1633. Performance samples are being analyzed, and the company expects to release detailed PFAS destruction results in the coming weeks. 374Water is also in discussions regarding a potential follow‑on industrial deployment and sees the campaign as a foundation for a scalable, recurring mobile services business.
374Water (SCWO) outlined a three-horizon strategy to scale its AirSCWO waste destruction platform and build recurring services revenue.
The company’s near-term focus is its Waste Destruction Services hub in Orlando, a fee-for-service model targeting difficult municipal, federal and industrial PFAS-contaminated wastes such as AFFF. Orlando is forecast at current planned capacity to generate approximately $3–5 million in annual revenue, with an expansion plan aiming to increase capacity about 3–4 times and target $10–14 million in annual revenue, depending on waste mix, utilization and pricing. Orlando is also the first hub in a federal hub-and-spoke strategy supported by a Defense Innovation Unit Success Memo and a strategic agreement with Arcadis, which the company believes can enable rapid federal contracting via Other Transaction Authority.
The “Next” horizon is regional biosolids infrastructure, anchored by projects in Orlando, Orange County (CA), St. Cloud (MN) and Olathe (KS), where an approximately $4.8 million purchase order covers AirSCWO equipment and operations. Longer term, 374Water aims to replicate its U.S. WDS and biosolids models globally through owned facilities, licensing, joint ventures and strategic partnerships that leverage its technology and proprietary operating data while accessing partners’ capital and local market reach.
374Water (NASDAQ:SCWO) announced it will exhibit at WEFTEC 2026, the Water Environment Federation's annual conference, held September 28-30, 2026 at the Ernest N. Morial Convention Center in New Orleans. The company will host attendees at Booth 2254, highlighting its AirSCWO supercritical water oxidation technology and Waste Destruction Services platform for permanent destruction of PFAS, biosolids, and hazardous organic waste.
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.
