374Water (SCWO)

Its core platform is AirSCWO, a proprietary system designed to use water at supercritical conditions to rapidly break down organic compounds. Under these conditions, organic waste can be converted into simpler outputs such as water, mineral solids, vent gas, and recoverable heat. The technology is intended to reduce the volume and environmental burden of waste streams that are often costly to transport, landfill, incinerate, or otherwise manage.

374Water positions AirSCWO as a solution for applications including sewage sludge, biosolids, food waste, industrial residues, and certain persistent contaminants often described as “forever chemicals.” The process is designed to mineralise organic material and produce outputs that can be more safely discharged, handled, or reused, depending on the waste profile and regulatory requirements.

The company operates in a market shaped by stricter environmental rules, pressure on municipalities to manage biosolids responsibly, and growing concern about PFAS and other long-lived pollutants. As an early-stage listed cleantech business, 374Water’s investment case depends on technology validation, customer adoption, project execution, regulatory drivers, and its ability to scale systems from demonstration and initial deployments into broader commercial use.
