Who We Are
374Water is a cleantech and industrial services company providing innovative solutions for organic waste destruction and sustainable wastewater treatment within Industrial, Federal, and Municipal markets in full compliance with environmental regulations.
Our proprietary technology sustainably eliminates non-hazardous and hazardous organic wastes and contaminants, converting waste into clean, reusable water, inert minerals, and recoverable energy.
Our Story
374Water is a pioneer in the commercialization of Supercritical Water Oxidation—or “SCWO”— technology, capable of converting organic waste, PFAS (forever chemicals), into minerals, and clean water.
SCWO technology as a solution for safe wastewater treatment is proposed based on research underway at Duke University in Durham, NC in response to a Gates Foundation challenge. The Foundation finds merit in Duke’s proposal and provides development funding.
374Water develops AirSCWO technology and files an additional 4 patents and 7 provisional patents. AirSCWO is implemented in projects spanning more than 16 different waste streams.
374Water is listed on the NASDAQ stock exchange and trades as SCWO.
374Water signs its first commercial contract with Orange County Sanitaion District in southern California and manufacturing begins in Kokomo, IN.
Under new leadership, 374Water secures capital funding and expands growth strategies.
374Water operates multiple commercial scale AirSCWO systems and has executed numerous contracts for the destruction of wastes including sludges/biosolids, Aqueous Film-Forming Foam (AFFF) and AFFF rinse water, Granular Activated Carbon (GAC), Ion Exchange resin (IX), and landfill leachate for Municipal, Federal, and Industrial customers.
374Water currently has clients and partners across Federal, Municipal and Industrial markets.
