374Water Inc. (OTCQB:SCWO) a leading sustainability innovator in the water and waste industries announced today that management will be participating in the 8th Annual Roth London Conference June 21-23, 2022 London, England.

The Company's participation follows third party validation and momentum from recent announcements, including:

• Orange County Sanitation District ("OC San"), of Fountain Valley, California, has purchased a 374Water AirSCWO™ system as part of an agreement to demonstrate a commercial-scale system to treat raw primary and secondary sludge, biosolids, and food waste.
• U.S. Department of Energy (DOE) and Israel's Ministry of Energy (MoE), along with the Israel Innovation Authority, have selected 374Water and Environmental Services Company, Ltd. (ESC) to conduct a cleantech project through the Binational Industrial Research and Development (BIRD) Energy program. 374Water and ESC will adapt and deploy an AirSCWO™ Nix6 system to harness energy and resource recovery from hazardous organic waste using supercritical water oxidation. The $3.5M USD project will accelerate technology innovation on the water-energy nexus. BIRD Energy will contribute $900,000 USD.

374Water's revolutionary AirSCWO technology converts waste to recoverable energy, water, and minerals, while eliminating organic pollutants including "forever" chemicals such as PFAS.
