374Water Inc (NASDAQ:SCWO, FRA:8LL) announced that its mobile AirSCWO system has been deployed for its first commercial project, marking the start of on-site operations under the company’s waste destruction services platform.
The unit left the company’s manufacturing and testing facility in Orlando, Florida on May 7 and arrived in St Cloud, Minnesota on May 11, where it will be used in a pilot program scheduled to run through mid-September 2026.
The deployment is being carried out under a $600,000 contract with the City of St Cloud, in partnership with Barr Engineering. The project involves the destruction of PFAS-contaminated biosolids and water treatment residuals at the city’s Nutrient, Energy, and Water Recovery Facility, including both undigested and post-thermal hydrolysis digested waste streams.
374Water said the pilot represents its first revenue-generating use of the mobile AirSCWO system and is intended to help evaluate operational performance in a real-world setting.
The company also said the results could inform broader adoption by the State of Minnesota for PFAS waste destruction applications, with potential longer-term revenue implications depending on outcomes.
The company estimates that a single mobile AirSCWO unit could generate between $500,000 and $1.5 million in annual revenue, depending on deployment frequency, waste type, and contract structure. It added that the St Cloud project will serve as an initial test case for those assumptions.
“Watching this mobile AirSCWO system leave our facility for its first commercial deployment is a defining moment for 374Water,” the company’s chief operating officer Brad Meyers said in a statement.
“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.”
The mobile system is intended to complement 374Water’s fixed-site waste destruction operations, including a recently announced five-year waste destruction services license with the City of Orlando. The company said the combination of mobile and stationary units is designed to broaden the types of sites and waste streams it can address.
374Water said it will provide updates on the St Cloud pilot and the performance of the mobile system as the program progresses.
