PFAS On Wheels: 374Water’s Mobile AirSCWO™ Brings “Forever Chemical” Destruction to St. Cloud

374Water Inc. (NASDAQ: SCWO) is rolling out its first mobile AirSCWO™ system to St. Cloud, Minnesota, where it will be used in a pilot program to destroy PFAS “forever chemicals” in wastewater. For investors, this is a key test of the company’s ability to deliver on‑site waste destruction services instead of relying only on fixed facilities.

374Water and the St. Cloud Pilot

The mobile unit will treat PFAS‑contaminated biosolids, water treatment residuals, and spent granular activated carbon (GAC) at the City of St. Cloud’s Nutrient, Energy, and Water Recovery Facility over several months. The goal is to show that 374Water’s supercritical water oxidation technology can work reliably at a customer site on multiple waste streams.

How AirSCWO™ Destroys PFAS

374Water’s AirSCWO™ platform uses high temperature and pressure to push water into a supercritical state, where it rapidly breaks down organic pollutants, including PFAS, into simple end products like water, nitrogen, and carbon dioxide. In earlier runs, the process has delivered very high PFAS destruction rates, making it attractive for communities facing stricter regulations.

Waste Destruction Services and Investor Takeaways

This deployment also advances 374Water’s Waste Destruction Services (WDS) model, which aims to generate recurring revenue by offering PFAS destruction as a service rather than only selling equipment. While 374Water (SCWO) is still an early‑stage cleantech stock, successful pilots like St. Cloud could help build customer confidence and support wider adoption of mobile PFAS treatment.
