Critical Milestone Project with Direct Implications for 2026 Commercial Sales Efforts
MORRISVILLE, N.C., Dec. 30, 2025 (GLOBE NEWSWIRE) — 374Water Inc. (NASDAQ: SCWO) (“374Water” or the “Company”), a global leader in organic waste destruction technology and services for the industrial, municipal, and federal markets, today announced it has been awarded a Waste Destruction Services (“WDS”) project to eliminate per- and polyfluoroalkyl substances (“PFAS”) in biosolids and water treatment residuals for the City of St. Cloud. The project was delivered by the Legislative-Citizen Commission on Minnesota Resources (“LCCMR”) and the State’s Environment and Natural Resources Trust Fund (“ENRTF”).
“We want to thank the LCCMR and the City of St. Cloud for their partnership and trust in 374Water,” said Stephen J. Jones, Chairman and Interim President and Chief Executive Officer of 374Water. “Minnesota has long been a national leader in confronting PFAS contamination, underscored by a landmark $850 million settlement with a large industrial manufacturer over PFAS-related damage to drinking water and natural resources in the Twin Cities region in 2018.
“This high-profile project provides an excellent opportunity to leverage our AirSCWO PFAS destruction technology on behalf of a U.S. state seeking to solve PFAS-related waste challenges. We look forward to working with our partners and stakeholders in this project to recognize AirSCWO’s unique ability to eradicate PFAS contamination in sludge, and safeguard public health,” concluded Mr. Jones.
374Water’s St. Cloud PFAS Water Remediation Project
PFAS, a class of persistent, man-made “forever chemicals” that accumulate in wastewater systems and the environment, are increasingly found in municipal biosolids. PFAS have been shown to pose significant risks to human health and the environment resulting in escalating demand for reliable and scalable PFAS destruction technologies.
374Water is part of a project team comprised of Barr Engineering Co. in Minneapolis, MN; University of St. Thomas in St. Paul, MN; Minnesota Technical Assistance Program (“MnTAP”) at the University of Minnesota in Minneapolis, MN; and the City of St. Cloud, MN. The City of St. Cloud project will utilize 374Water’s mobile AirSCWO 1 System to eliminate PFAS in undigested and post-thermal hydrolysis digested biosolids and spent granular activated carbon (“GAC”). The initiative will provide a comprehensive evaluation of PFAS destruction efficiency and examine options for disposing or repurposing of the treated water and solids.
The goal of this public-private partnership is to showcase AirSCWO‘s ability to destroy PFAS in a range of wastes. Based on increasing prevalence of PFAS contamination in domestic water supplies in Minnesota communities, the State has prioritized funding projects providing clean, sustainable drinking water. The project is expected to commence in April 2026.
