374Water Inc (NASDAQ:SCWO, FRA:8LL) has released US government-backed test results demonstrating the performance of its AirSCWO technology in destroying PFAS, a group of persistent environmental contaminants.
The results stem from the company’s participation in a project led by the Defense Innovation Unit (DIU) and the Environmental Security Technology Certification Program (ESTCP), with independent evaluation and presentation by Arcadis.
According to the company, AirSCWO permanently destroys PFAS rather than concentrating or filtering them. Testing across six PFAS-contaminated waste streams showed the system met or exceeded all key performance objectives.
Liquid waste streams achieved more than 99.9% destruction and removal efficiency (DRE), while solid waste streams exceeded 90%.
"Performing technical demonstrations at scale, such as this DIU project, are essential to build trust within government agencies," said Howard Teicher, 374Water's vice president, government.
"Watching AirSCWO PFAS-contaminated waste streams, in some cases to a NON-DETECT or single-parts per trillion level, affirms that this technology is ready for operational use."
Dr Raj Melkote, 374Water’s chief technology officer, described the results as “a defining moment for AirSCWO and for the PFAS destruction market as a whole.”
"What Arcadis and Clean Earth helped us demonstrate is not just that AirSCWO works - it's that it works across the hardest waste streams, under the most rigorous federal protocols, with third-party analytical data that leaves no room for ambiguity.”
