374Water Inc (NASDAQ:SCWO, FRA:8LL) announced that it has received approval from the City of Orlando to provide waste destruction services at the Iron Bridge Regional Water Reclamation Facility, marking a step toward expanding the company’s commercial operations for the treatment of organic waste streams.
The cleantech company said the approval grants it a license to operate its Waste Destruction Services platform at the facility for an initial five-year term, with options for two additional five-year extensions.
The authorization follows the completion of a full-scale demonstration of 374Water’s AirSCWO system at the Iron Bridge facility.
According to the company, the project achieved more than 99.95% destruction of per- and polyfluoroalkyl substances (PFAS) in biosolids and other waste streams, including aqueous film-forming foam (AFFF).
With the system already installed at the site, the company said it expects to shorten the timeline between regulatory approval and the launch of commercial services. Planned steps include expanding holding tank capacity, receiving larger waste volumes, scaling related assets and logistics infrastructure, and optimizing throughput and operating economics.
374Water said the initiative is intended to create a recurring revenue stream while also providing the City of Orlando with an additional source of revenue.
“The City’s approval marks an important milestone as we transition from demonstrated destruction technology to a scalable services platform designed to meet growing demand for PFAS destruction,” 374Water’s chief operating officer Brad Meyers said.
“With our AirSCWO system already in place, we believe we are positioned to deliver commercial waste destruction services as we accelerate the next phase of market expansion.”
The partnership between 374Water and the City of Orlando began in March 2024 with the deployment of a commercial-scale AirSCWO system at the Iron Bridge facility. In May 2025, the two parties launched a 90-day biosolids destruction program to test the system’s ability to eliminate PFAS-contaminated and other organic waste streams. The company said the newly approved license and permit followed the successful completion of that program.
Separately, 374Water provided an update on its project with the Orange County Sanitation District (OC San) in California. The company said it spent 2025 implementing engineering and design improvements to its next-generation AirSCWO system to increase throughput, reliability and long-term performance for biosolids and sludge destruction.
Those enhancements extended the delivery timeline beyond the previously expected 2025 date, the company said. As a result, revenue associated with the OC San system, which had been included in earlier 2025 guidance, is now expected to be recognized in 2026.
374Water said it continues to work with OC San to finalize site infrastructure improvements and complete system optimization.
