Summary:

Supercritical Water Oxidation (SCWO) is an advanced oxidation method that can treat a wide range of organic wastes, in particular wet wastes and slurries such as human waste, food waste, fats/oils/greases, used motor oils, AFFF, spent chemicals and more. It is a transformative technology that utilizes the unique properties of water above its critical point: 374°C and 221 bar (705 °F and 3200 psi). At these conditions, in the presence of oxygen, organics are rapidly converted to water, inert minerals and gases, and reusable heat with generally more than 99.9% destruction of all organic compounds. 374Water AirSCWO systems are prefabricated, modular and compact "omniprocessors" that rapidly convert organic waste into clean water, heat and electricity and inert minerals. Invented by engineers from Duke University in Durham, North Carolina, AirSCWO systems occupy a small footprint and provide a clean, energy-neutral and sustainable solution at an affordable cost. The technology is truly disruptive as it is one of the few technologies that will eliminate PFAS and other "forever" chemicals.
