First Deployment of Mobile System Validates New Revenue Channel for Company's Waste Destruction Services Platform
MORRISVILLE, NC / ACCESS Newswire / May 12, 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 that its mobile AirSCWO system departed the Company's Orlando, Florida manufacturing and testing facility on May 7, 2026, en route to St. Cloud, Minnesota, and arrived May 11, 2026 for its first deployment.
The deployment represents a significant commercial milestone for 374Water, marking the inaugural revenue-generating operation of the mobile AirSCWO system and providing the Company with its first real-world assessment of market demand for additional mobile units.
First Deployment: St. Cloud, Minnesota
The mobile AirSCWO system is being deployed under a $600,000 Waste Destruction Services contract with the City of St. Cloud, in partnership with Barr Engineering, to destroy PFAS-contaminated biosolids and water treatment residuals at the City's Nutrient, Energy, and Water Recovery Facility. Pilot operations are scheduled to run through mid-September 2026, processing undigested and post-thermal hydrolysis digested waste.
This engagement also carries significant long-term commercial potential. A successful pilot is expected to support the State of Minnesota's evaluation of AirSCWO for the destruction of PFAS-laden wastes - an outcome the Company believes could generate multiple millions of dollars in revenue, including recurring annual revenue from ongoing operations and services.
Mobile AirSCWO: A New Revenue Channel
374Water believes its mobile AirSCWO system represents a distinct and scalable revenue opportunity. The system is designed to serve remediation projects, AFFF takeback programs, government facilities, and industrial sites where permanent infrastructure is not preferred or available - markets that are not accessible through the Company's fixed-site Waste Destruction Services model alone.
The Company estimates that a single mobile AirSCWO system has the potential to generate between $500,000 and $1.5 million in annual revenue, depending on deployment cadence, waste stream composition, and contract structure. The St. Cloud deployment will serve as a live validation of these economics and of the operational model for future mobile deployments.
"Watching this mobile AirSCWO system leave our facility for its first commercial deployment is a defining moment for 374Water," said Brad Meyers, Chief Operating Officer. "This deployment is about more than St. Cloud - it's proof that our technology can go where the problem exists. We're demonstrating a new commercial model, and the results of this pilot will inform how we scale mobile capacity to meet what we believe is substantial unmet demand."
The mobile AirSCWO system, departing 374Water's manufacturing and commissioning facility in Orlando, FL, is designed for on-site waste destruction with minimal infrastructure.
Expanding the Waste Destruction Services Platform
The mobile AirSCWO system complements 374Water's growing portfolio of fixed-site Waste Destruction Services operations, including the Company's recently announced five-year WDS license with the City of Orlando. Together, the mobile and fixed-site offerings give 374Water a flexible, scalable services platform capable of addressing the full range of customer environments and project types.
The Company will provide further updates on the St. Cloud deployment, pilot operations, and the progress of the mobile system program as they become available.
