Arizona Tribune - 374Water Announces Publication of "Destruction of PFAS-Laden Ion Exchange Resin using Supercritical Water Oxidation" White Paper

DURHAM, NC / ACCESS Newswire / January 23, 2025 / 374Water Inc. (NASDAQ:SCWO) ("374Water") (the "Company"), a global leader in organic waste destruction technology for the municipal, federal, and industrial markets, today announced the publication of their new white paper, "Destruction of PFAS-Laden Ion Exchange Resin using Supercritical Water Oxidation", demonstrating the ability of its supercritical water oxidation (SCWO) system (AirSCWO) to destroy spent anion IX (AIX) resin laden with per- and polyfluoroalkyl substances (PFAS) "Forever Chemicals".

The paper provides an overview of the use of Ion exchange (IX) resins that are used widely across various industries due to their proven performance in removing nuisance contaminants that impact product quality and safe effluent discharge. However, once the resin is spent (i.e. saturated), effective disposal methods must be used to prevent the release of concentrated hazardous contaminants to the environment.

Of particular concern is the disposal of spent anion IX (AIX) resin laden with per- and polyfluoroalkyl substances (PFAS), a group of synthetic chemicals that are known as "forever chemicals" because they do not break down in the environment and have been linked to a variety of health problems like thyroid disease, hormonal and fertility problems, high cholesterol and cancer. PFAS can be found in a variety of industries and products including firefighting foams, food packaging, cleaning products, and paints. The current status quo of landfilling or incinerating PFAS-laden spent AIX resin can lead to the leaching of PFAS into soil and groundwater systems and/or release of PFAS into the air. Recent Environmental Protection Agency regulatory requirements for drinking water and in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are focused on eliminating existing and emerging contaminants including PFAS.

The white paper further provides a background on treating PFAS using Anion Exchange Resins and shows successful bench and commercial scale field trial results from running PFAS-laden spent AIX through 374Water's AirSCWO system. On both the lab-scale and commercial scale, the AirSCWO system consistently achieved >99.9% total PFAS elimination of saturated AIX resins in a matter of seconds.

"Our newest white paper highlights how our AirSCWO technology is positioned to meet the growing spent media market, estimated at $1.3 billion as of 2024, at a level that exceeds the performance requirements for PFAS treatment," said Chris Gannon, CEO of 374Water. "AirSCWO presents a revolutionary approach to PFAS destruction, offering unmatched efficiency and safety for treating spent PFAS-laden AIX resin. We invite you to learn more about the AirSCWO System's ability to destroy non-hazardous and hazardous organic wastes and, in the process, produce safe dischargeable water streams, safe mineral effluent, safe vent gas, and recoverable heat energy."
