SCWO•Revenue expectations and data analysis
374Water estimates each mobile AirSCWO unit could generate USD 500,000 to USD 1.5 million in annual revenue depending on utilization and contract terms.
The company is analyzing Phase 1–3 performance data, citing preliminary destruction results consistent with prior campaigns.
Phase 3 of St. Cloud deployment completed
374Water completed Phase 3 of its mobile AirSCWO deployment in St. Cloud, Minnesota, under a USD 600,000 waste destruction services contract.
This concluded a three-phase campaign that treated three biosolids feedstocks from June 1 to July 31 with no operational issues.
Phase 4 begins and company sees follow-on potential
Phase 4 began Aug. 10, targeting Class B biosolids blended with spent granular activated carbon from a drinking water plant in Cottage Grove, Minnesota.
The pilot is expected to support Minnesota’s assessment of AirSCWO for permanent PFAS destruction.
A potential follow-on opportunity could drive “multiple millions of dollars” in revenue, according to the company’s estimate.
