Welcome to our dedicated page for 374Water news (Ticker: SCWO), a resource for investors and traders seeking the latest updates and insights on 374Water stock.
374Water Inc. develops AirSCWO™, a supercritical water oxidation technology used to destroy organic waste streams for municipal, federal and industrial customers. Company news centers on PFAS destruction results, biosolids and AFFF treatment demonstrations, Waste Destruction Services activity, and deployments of fixed and mobile AirSCWO systems.
Recurring updates also cover commercial agreements, municipal wastewater projects, government demonstration work, operating results, capital management, organizational changes and board appointments. The company frames its business around converting contaminated liquid and slurry waste streams into dischargeable water, mineral effluent, vent gas and recoverable heat.
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%.
Treated liquid effluent was reported to meet U.S. EPA maximum contaminant levels for all regulated PFAS, indicating potential for direct discharge. Volatile fluorinated stack emissions were near zero, at 0.0005 g/hour versus a PFAS throughput of 16.6 g/hour, and broader organics were reduced to near-non-detect. The ERDC TR-26-19 report, performed under the Army’s Environmental Quality Technology 6.4 Program, supports 374Water’s strategic collaboration with Arcadis to pursue federal and commercial PFAS destruction contracts.
374Water (NASDAQ:SCWO) announced a Memorandum of Understanding with Arcadis U.S. to jointly pursue federal, municipal, and industrial contracts for permanent destruction of PFAS-impacted waste, including aqueous film-forming foam (AFFF), using 374Water’s AirSCWO supercritical water oxidation systems.
The MOU outlines development of turnkey PFAS destruction solutions and regional treatment hubs, with Arcadis expected to lead federal prime contracting, client interface, and regulatory/permitting work, while 374Water provides patented AirSCWO technology, waste destruction services, and system deployment and operation. The collaboration leverages a U.S. Department of Defense–sponsored demonstration in which AirSCWO achieved >99.9% PFAS destruction across hard-to-treat waste streams, including >99.99% destruction in concentrated AFFF. 374Water’s existing Orlando Waste Destruction Services facility will serve as a commercial reference hub, with additional regional hubs anticipated to support a long-duration federal PFAS remediation market.
374Water (NASDAQ:SCWO) appointed Charles “Chuck” Weiser, CPA, as Chief Financial Officer, effective immediately. He succeeds Interim CFO Adrienne Anderson, who will remain as a financial consultant focused on SEC reporting, compliance, and corporate finance activities.
Weiser, already a Board member and long-time investor, brings experience in finance, capital markets, strategic planning, and turnaround management to support commercialization and growth.
374Water (NASDAQ:SCWO), a cleantech and environmental services company, has been added to the Russell Microcap Index, effective after the close of U.S. markets on June 26, 2026.
The company expects enhanced institutional visibility while focusing on deploying its AirSCWO technology, expanding Waste Destruction as a Service, growing recurring revenue, and addressing PFAS and other organic waste streams.
374Water (NASDAQ:SCWO) reported Phase 1 completion of its mobile AirSCWO deployment in St. Cloud, Minnesota under a $600,000 waste destruction services contract. Phase 2 is underway, with steady operations and no major challenges. The pilot runs through mid-September 2026 and may support broader PFAS-destruction adoption.
According to 374Water, early field data align with prior campaigns, and the mobile unit is estimated to generate $500,000–$1.5 million in annual revenue per system, helping build a scalable, recurring mobile services business.
374Water (NASDAQ:SCWO) amended its license with the City of Orlando to fully build out a PFAS waste destruction and manufacturing hub at the Iron Bridge facility.
The expansion adds 88,000 gallons of tank storage, over 35,000 sq ft of space, and upgraded AirSCWO capacity. At initial scale, the WDS hub is expected to generate $3M–$5M in annual revenue, with negotiations underway to more than double destruction capacity and revenue potential.
374Water (NASDAQ:SCWO) completed the Factory Acceptance Test for its AirSCWO system for Orange County Sanitation District, a key deployment milestone.
The system is engineered to destroy PFAS, pharmaceuticals, and microplastics, achieve about 97% solids reduction and 99.99%+ PFAS destruction, and supports progress toward remaining $3M in contract milestones.
374Water (NASDAQ:SCWO)/b) provided a conference update highlighting growing interest in PFAS destruction and biosolids management.The company recently attended multiple water, waste, and military engineering conferences and will present SCWO-based PFAS and organic waste destruction research at the Battelle 2026 Chlorinated Conference in Fort Worth, Texas on June 1–2.
