374water Inc.
A maker of waste-destruction systems that turn organic waste into clean water, energy, and minerals. Its main product, AirSCWO™, uses supercritical water oxidation to destroy "forever chemicals" like PFAS that resist ordinary treatment. Founded in 2018 by Duke engineering professor Marc Deshusses, the technology grew out of the Bill & Melinda Gates Foundation's "Reinventing the Toilet Challenge." The name marks 374°C, the temperature where water reaches its critical point — a process Deshusses likens to "a pressure cooker on steroids."
