Applications And Markets



Specializing in advanced wastewater treatment technologies, addresses the challenging issue of per- and polyfluoroalkyl substances (PFAS) in wastewater through a unique and innovative process. Their approach involves a unique technology called Supercritical Water Oxidation (SCWO), which effectively destroys PFAS. Reaching a supercritical state where water behaves as both a liquid and a gas. This environment allows for rapid and complete oxidation of PFAS, transforming these harmful compounds into harmless substances like water, 

Residual & Biosolids

374water’s application of Supercritical Water Oxidation (SCWO) technology extends to the treatment of biosolids and residuals. In this process, biosolids and residuals are subjected to high temperatures and pressures, bringing water into a supercritical state. This unique state enables the water to act as both a solvent and a reaction medium, leading to the rapid and thorough oxidation of organic materials in the biosolids and residuals. This method effectively transforms these materials into simpler, non-toxic compounds

Industrial waste & Sludges

374water treats industrial sludge using Supercritical Water Oxidation (SCWO) technology, where sludge is exposed to high temperatures and pressures, converting water into a supercritical state. This facilitates the rapid oxidation of sludge components into simpler, harmless substances like water, salts and energy efficiently handling complex and hazardous materials in the sludge.

Food Waste

374water employs its Supercritical Water Oxidation (SCWO) technology to treat food waste. In this process, food waste is subjected to high temperatures and pressures, transforming water into a supercritical state. This enables the efficient breakdown of organic matter in the waste into simpler substances such as water, carbon dioxide, and salts. This method effectively manages the complexities of food waste, offering an environmentally friendly solution.

Landfill leachate

374water’s treatment of landfill leachate utilizes the Supercritical Water Oxidation (SCWO) technology. In this process, landfill leachate is exposed to high temperatures and pressures, which brings water into a supercritical state. This state aids in the efficient oxidation of contaminants within the leachate, transforming them into simpler, non-toxic substances like water, carbon dioxide, and salts. This approach effectively addresses the challenging composition of landfill leachate, providing an environmentally sound solution.



At 374Water, we are committed to the cities, districts and stats we live in. Our AirSCWO technology is an end-of-the-line solution for municipalities, treating biosolids, PFAS, leachate and other applications. Working closely with sanitation, water and public works teams we treat wastewater and eliminate hazardous materials while leaving behind only minerals, water and renweable energy


374Water’s AirSCWO (Supercritical Water Oxidation) technology presents a groundbreaking solution for the defense waste industry, especially in tackling contaminants like Per- and Polyfluoroalkyl Substances (PFAS) and Aqueous Film Forming Foam (AFFF).


Moreover, the efficiency and speed of the AirSCWO process make it a viable option for large-scale defense applications, where the rapid and safe disposal of hazardous waste is crucial. This technology not only addresses the immediate need for effective waste management but also contributes to a more sustainable approach in dealing with complex industrial wastes, aligning with environmental safety standards and regulations.


Oil & Gas

At 374Water, we understand the challenges the Oil and Gas industry faces when it comes to managing petroleum sludge. This hazardous waste, a byproduct of petroleum production and exploration, has long posed significant environmental and health risks. Traditional treatment methods, such as incineration, stabilization/solidification, oxidation, and bio-degradation, have their limitations and often fall short of providing a comprehensive solution.

Organic chemical & Pharmaceuticals

In the pharmaceutical sector, the technology addresses the growing concern over pharmaceutical waste, including expired drugs and manufacturing by-products. These wastes often contain active pharmaceutical ingredients that can be harmful to the environment and human health if not disposed of properly. AirSCWO provides a solution by oxidizing these compounds thoroughly, ensuring that they are broken down to a level where they pose no risk when released into the environment.

Waste management & Remediation

The effectiveness of AirSCWO technology in treating waste and residuals lies in its ability to handle various forms of waste, including sludge, hazardous materials, and complex organic compounds. This is particularly beneficial for industries dealing with challenging waste streams, such as pharmaceuticals, chemicals, and other sectors where traditional waste management methods fall short. The process not only minimizes the environmental impact by reducing the need for landfilling but also recovers energy and resources from waste, contributing to a more sustainable and circular approach to waste management.
