374Water Highlights Rising Demand for PFAS Destruction Technology After May Conference Tour
374Water Highlights Rising Demand for PFAS Destruction Technology After May Conference Tour
374Water Inc. said its recent May conference schedule showed growing market interest in its AirSCWO technology, a system designed to destroy PFAS and other difficult organic waste streams using supercritical water oxidation.
The cleantech company, listed on NASDAQ under the ticker SCWO, attended several major industry events in May 2026, including water, biosolids, solid waste, and military engineering conferences. According to Proactive Investors, the company said these meetings strengthened its view that wastewater operators, municipalities, and remediation groups are searching for better ways to manage PFAS-contaminated waste.
Conference Activity Points to Stronger PFAS Treatment Demand
374Water completed a busy May schedule with appearances at the Water Environment Federation’s Residuals, Biosolids and Treatment Technology Conferences in Kansas City and Atlantic City, the Federation of New York Solid Waste Association event, and the Society of Military Engineers Joint Engineer Training Conference & Expo in Portland.
The company said these events helped it connect with public-sector operators, engineers, and environmental decision-makers who face increasing pressure to address persistent contaminants. PFAS, often called “forever chemicals,” have become a major focus for regulators and utilities because they can remain in the environment for long periods and are difficult to remove from waste streams.
AirSCWO Technology Targets Difficult Waste Streams
374Water’s AirSCWO platform uses supercritical water oxidation to break down organic waste. The company is positioning the system as a solution for materials such as PFAS-laden biosolids, AFFF firefighting foam waste, and other complex waste streams that traditional treatment methods may struggle to handle.
Project partners from the City of Olathe, Kansas, also joined 374Water during the May events. Olathe is expected to receive the company’s next AirSCWO system for processing biosolids containing PFAS.
Company Says Operators Need New Solutions
Sunny Viswanathan, vice president of solutions at 374Water, said the company believes waste operators are running out of practical options for dealing with PFAS-related materials. He said the market is not simply looking for another new product, but for a needed solution to a growing environmental challenge.
This message reflects a wider industry concern: municipalities and industrial operators must manage contaminated waste while also meeting stricter environmental expectations. As awareness of PFAS risks grows, technologies that can destroy contaminants rather than only move or concentrate them are receiving more attention.
Next Stop: Battelle 2026 Chlorinated Conference
374Water’s next major event is the Battelle 2026 Chlorinated Conference in Fort Worth, Texas. The company has secured two presentation slots covering the destruction of 6PPD-Q contaminated waste and the treatment of waste containing 1,4-Dioxane and PFAS.
These waste categories are becoming more important because they are linked to regulatory action, environmental remediation spending, and infrastructure planning. By presenting results and use cases at Battelle, 374Water aims to strengthen its position with engineers, regulators, and potential project partners.
Defense-Related PFAS Destruction Also in Focus
A Wednesday session focused on the U.S. Department of Defense will present large-scale field demonstration results for PFAS destruction in AFFF concentrate using supercritical water oxidation. The session will be chaired by Dr. Craig Divine, senior vice president at Arcadis and a partner involved in the work.
AFFF, or aqueous film-forming foam, has been widely used in firefighting, especially at military and aviation sites. Because some AFFF products contain PFAS, disposal and treatment have become a serious environmental and operational issue.
Why This Matters
The announcement suggests that 374Water is trying to move from technology development toward broader commercial use. The company’s conference activity gives it a platform to show how AirSCWO may fit into real-world waste treatment projects, especially where PFAS destruction is a high priority.
For cities, utilities, military sites, and environmental contractors, PFAS management is no longer a distant issue. It is becoming part of daily planning, budgeting, and compliance work. If 374Water can prove its technology at scale, it may benefit from rising demand for permanent destruction solutions.
Market Outlook
While 374Water’s opportunity appears promising, the company still operates in a developing market. Adoption will likely depend on field performance, cost efficiency, regulatory acceptance, and the ability to deploy systems reliably. Investors and industry observers will be watching closely as the company advances its next demonstrations and customer deployments.
The latest update shows that PFAS destruction remains a fast-moving area of environmental technology, and 374Water is working to position AirSCWO as a serious option for organizations facing hard-to-treat waste.
