374Water to present new AirSCWO destruction data at WEFTEC 2026

374Water will present new data on its AirSCWO supercritical water oxidation platform at WEFTEC 2026 in New Orleans, with results spanning PFAS, tire-derived 6PPD-q and pharmaceutical waste. The company says the findings strengthen its case for permanent destruction of emerging contaminants across municipal, federal and industrial markets.

Why it matters: - 374Water is positioning AirSCWO as a single platform for permanent destruction of multiple hard-to-treat contaminants. - The new WEFTEC data could matter for municipalities, federal agencies and industrial generators facing PFAS and other emerging pollutant pressure. - The presentation also adds another data point to 374Water’s federal PFAS destruction effort and its partnership framework with Arcadis.

What happened: - 374Water said it will present new destruction-efficiency data for AirSCWO at WEFTEC 2026 in New Orleans. - The 30-minute podium presentation is scheduled for Wednesday, Sept. 30, 2026, from 2:30 p.m. to 3:00 p.m. CT at the New Orleans Convention Center. - David Garb, 374Water’s Technical Solutions Manager, will deliver the presentation. - The session is titled “Fighting PFAS With Fire: Advanced Thermal Conversion for Biosolids Management.” - 374Water will also exhibit at booth #2254 with executives and team members present.

The details: - The presentation is titled “Application of Supercritical Water Oxidation for Treating Wastes Contaminated with PFAS, 6PPD-Q, and Other Emerging Pollutants.” - Co-authors are Sudhakar “Sunny” Viswanathan, David Garb and Naomi Senehi of Aerzen USA. - The data draws on commercial-, bench- and laboratory-scale studies. - 374Water says the results show AirSCWO can treat a broad range of contaminants of emerging concern with only moderate changes to operating conditions. - The company says supercritical water oxidation differs from incineration and other thermal methods in reaction environment, emissions profile, effluent quality and monitoring requirements. - In a commercial-scale demonstration, PFAS in biosolids showed greater than 99.4% destruction and removal efficiency for every PFAS compound detected. - For 6PPD-q, the process reduced the tire-derived contaminant from 18 µg/L to non-detect, for a DRE greater than 99.99%. - For mixed pharmaceutical waste, the process achieved greater than 99% reduction in chemical oxygen demand across variable feedstock blends. - The resulting effluent was compliant with the existing industrial site. - The abstract says the studies examined alkaline addition, reactor temperature, operating pressure, mixing intensity and influent water content. - Performance was measured using pressure drop behavior, temperature stability, CO emissions, metals content in liquid effluent and physical characteristics of the effluent streams. - The work used wastewater sludge, analytical-grade 6PPD-q and a pharmaceutical waste blend containing solvents and organic contaminants. - The company included more information in a B2i Digital Featured Company profile.

Between the lines: - 374Water is leaning on broad-spectrum treatment claims rather than a single-contaminant pitch. - That framing matters because the company is arguing that broad applicability could improve the economics of SCWO versus technologies built for one contaminant class. - The abstract says comparisons across waste-treatment technologies are often incomplete because monitoring and verification standards differ. - The 6PPD-q focus also signals an attempt to expand beyond PFAS into another emerging contaminant with growing regulatory attention. - The company’s messaging suggests it is trying to show that AirSCWO destroys contaminants rather than transferring them into another waste stream.

What's next: - 374Water is continuing to pursue federal procurement opportunities for PFAS destruction with Arcadis under a partnership framework. - The company says those opportunities include sludge and biosolids in remote locations, along with other emerging contaminants. - Investors and waste-sector customers will be looking for whether the WEFTEC presentation helps convert technical results into commercial deployments.

The bottom line: - 374Water is using WEFTEC to argue that AirSCWO can destroy PFAS, 6PPD-q and pharmaceutical waste on one platform, and that breadth is central to its commercialization case.
