About this update from 374water Inc.
The mobile AirSCWO brings the full capability of larger modular systems for wastes that cannot be transported and for onsite pilot demonstrations MORRISVILLE, NC / ACCESS Newswire / June 30, 2026 / 374Water Inc. (NASDAQ:SCWO) ("374Water" or the "Company"), a leading cleantech and environmental services company deploying supercritical water oxidation technology for the permanent destruction of organic waste through its proprietary AirSCWO™, today announced the completion of Phase 1 of the St. Cloud, Minnesota campaign and provided an update on operations of its mobile AirSCWO system. Project Update The St. Cloud deployment is being conducted under a $600,000 Waste Destruction Services contract with the City of St. Cloud, in partnership with Barr Engineering, at the City's Nutrient, Energy, and Water Recovery Facility. This facility is a national leader, known for its innovative resource recovery practices. Receiving approximately 10 million gallons daily, the facility exemplifies a culture of innovation as it consistently pioneers and pilots industry-changing technologies. The pilot program is scheduled to run through mid-September 2026, processing undigested and post-thermal hydrolysis digested waste streams as part of the State of Minnesota's LCCMR-supported evaluation of AirSCWO technology for the destruction of PFAS-laden wastes. 374Water's mobile AirSCWO system departed the Company's Orlando testing facility in May. Phase 1 Complete: Class B Biosolids Processing The mobile AirSCWO system has successfully completed Phase 1 of the St. Cloud deployment, a four-week processing campaign targeting Class B biosolids at solids concentrations of up to 10%. The Company is conducting analyses of Phase 1 performance data and is seeing positive early results consistent with previous AirSCWO campaigns, providing yet another proof point of technology validation. The mobile system allows for minimal infrastructure in places where that is not viable. Phase 2 Underway: Class A Lystek Biosolids Building on the completion of Phase 1, the 374Water field team is now one week into Phase 2 of the deployment, which involves processing Class A Lystek biosolids. Operations have been steady, with no major operational challenges encountered to date. The Company is pleased with the pace of the program and the performance of the mobile system under field conditions. The campaign has now seen multiple types of biosolids successfully processed with more to come as the project moves forward. A successful pilot is expected to support Minnesota's broader assessment of AirSCWO for permanent PFAS destruction - an outcome the Company believes could generate multiple millions of dollars in revenue, including recurring annual revenue from ongoing operations and services. The mobile AirSCWO system is estimated to have the potential to generate between $500,000 and $1.5 million in annual revenue per unit, depending on deployment cadence, waste stream composition, and contract structure. We are seeing eager demand for this system and are excited to announce the successive campaign following successful performance in Minnesota.
