Supercritical water oxidation shows global potential for changing how the world treats waste
07/20/2021 EDMONTON, AB; NEW YORK, NY TSX, NYSE:STN
374Water Inc., a social impact, cleantech company located in Durham, North Carolina, and Stantec, a global design firm and recognized leader in integrated organics management and resource recovery, have entered into an agreement whereby Stantec will provide services to evaluate and support 374Water’s design of its AirSCWO Nix6 systems.
Under the terms of the agreement, Stantec will act as owner’s representative by participating in design process meetings, interdisciplinary evaluations, and operations review support.
SCWO is an advanced oxidation method that handles a variety of organic wastes, in particular wet wastes in concentrated slurries such as wastewater sludge, biosolids, and agricultural, pharmaceutical and chemical wastes. SCWO uses the unique properties of water above its critical point (374 °C and 221 bar). Combining oxygen with supercritical heat and high pressure, organics are rapidly converted to clean water, inert gases, recoverable mineral salts, and reusable heat with >99% reduction in solids volume. The process has proven effective at eliminating emerging contaminants such as PFAS, 1,4-Dioxane, drugs, microplastics, and other pathogens. 374Water is commercializing its AirSCWO Nix6 systems as decentralized, prefabricated, compact, and modular units.
“We took notice of 374Water and their supercritical water oxidation (SCWO) process early on, identifying this technology's potential. Stantec has long been at the forefront in sustainable resource recovery. We look forward to providing design services and third-party validation to 374Water as owner’s representative," said Stantec’s VP, Michael McWhirter.
Co-founder and CEO of 374Water, Kobe Nagar, commented, “We are pleased that Stantec has agreed to act as our owner's representative in the design and validation of AirSCWO Nix6 units. As a trusted global service provider, Stantec leads the industry with their innovative approach, balancing prudent technological innovation with environmental, regulatory, and economic needs. They're a global company serving clients both large and small, and we're pleased to have them provide oversight and validation to our process.”
This technology – employing circular economy principals – has been funded by the Gates Foundation and recently closed its first round of equity funding. The first units are expected to be deployed in the first half of 2022.
