AirSCWO™ is a physical-thermal process powered by water above its critical point (374°C and 221 bar) and air that yields a highly effective oxidation reaction that completely eliminates organic compounds. The reaction generates energy and safe products that can be recovered and reused.
Supercritical Water Oxidation (SCWO)
What is Supercritical Water Oxidation?

how it works
AirSCWO™ harnesses an efficient decentralized solution for treating a broad range of waste feedstocks rapidly, continuously, cost-effectively and with unprecedented reliability.
374Water’s AirSCWO™ Systems are compact, modular, and prefabricated units that are energy efficient and cost effective.
