374Water Inc. has appointed Chuck Weiser, CPA, as Chief Financial Officer, effective immediately. The company, a cleantech and environmental services firm deploying supercritical water oxidation technology for the destruction of organic waste streams, announced the leadership change today. Mr. Weiser succeeds Adrienne Anderson, who transitions from her role as Interim Chief Financial Officer.

Ms. Anderson will continue supporting 374Water as a financial consultant. Her focus will remain on SEC reporting, compliance, and corporate finance initiatives. The company operates in the environmental services sector, utilizing advanced technology to process organic waste streams.

374Water Inc. has successfully completed Phase 1 of its mobile AirSCWO system deployment in St. Cloud, Minnesota, and has initiated Phase 2 of the project. The company is processing biosolids under a $600,000 Waste Destruction Services contract with the City of St. Cloud, in partnership with Barr Engineering. The pilot program is scheduled to run through mid-September 2026 and targets the destruction of PFAS-laden wastes as part of an evaluation supported by the State of Minnesota's LCCMR.

Project Details and Phase 1 Results

The deployment is taking place at the City's Nutrient, Energy, and Water Recovery Facility, a site known for its innovative resource recovery practices. During Phase 1, the mobile AirSCWO system processed Class B biosolids at solids concentrations of up to 10% over a four-week period. The company reported that performance data from this phase shows positive early results consistent with previous AirSCWO campaigns, validating the technology.

Phase 2 Operations and Commercial Outlook

Building on the initial success, the field team is now one week into Phase 2, which involves processing Class A Lystek biosolids. Operations have been steady with no major challenges encountered to date. A successful pilot is expected to support Minnesota's broader assessment of AirSCWO for permanent PFAS destruction. 374Water estimates that a single mobile AirSCWO system has 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.

Future Deployments

Beyond the current project, 374Water is actively developing additional projects to demonstrate the commercial capabilities of the AirSCWO system in a mobile configuration. The company indicated strong interest across multiple end markets. Brad Meyers, Chief Operating Officer of 374Water, stated that the deployment validates the reliability of the technology and the commercial model, noting that demand for mobile AirSCWO services is growing.
