AirSCWO - Supercritical Water Oxidation (SCWO) Technology
What is Supercritical Water Oxidation? 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.
Shifting the waste management paradigm
374Water’s AirSCWO™ Nix systems significantly alter how we manage the waste our society generates. It is a disruptive technology that moves us from treatment and disposal to elimination and resource recovery.
AirSCWO harnesses is an efficient decentralized solution for treating a broad range of waste feedstocks rapidly, continuously, cost-effectively and with unprecedented reliability.


374Water’s AirSCWO Nix Systems are compact, modular, and prefabricated units that are energy efficient and cost effective.
AirSCWO™ harnesses the power of supercritical water without compromising on operational, performance and resource recovery targets.
