Perma-Fix Environmental Services Inc. (NASDAQ: PESI) announced completion of a PFAS treatment project for Four Rivers Nuclear Partnership, the Department of Energy contractor managing environmental cleanup at the Paducah Site.

The company treated approximately 1,500 gallons of PFAS-contaminated liquids using its patent-pending Perma-FAS destruction technology. The work involved two tasks: transportation and treatment of legacy aqueous film-forming foam and onsite remediation of a tank and bladder containing PFAS liquids.

"Successfully completing this project for a DOE contractor demonstrates Perma-Fix's unique capabilities in treating highly complex waste streams and the real-world application of our Perma-FAS destruction technology," said Mark Duff, chief executive officer.

The Perma-FAS process is a water-based treatment technology that converts carbon-fluorine compounds into mineralized fluoride through catalytic reactions. The system operates at elevated temperatures and uses catalytic materials to break down carbon-fluorine bonds in PFAS molecules.

According to the company, the process produces a water stream for conventional disposal while recycling reactants to enhance efficiency. Based on testing and operational data, the technology achieves destruction efficiencies approaching 99.9999% under appropriate operating conditions.

PFAS compounds, known as "forever chemicals," have been used in industrial applications and consumer products due to their resistance to heat, water, and oil. Their environmental persistence has created demand for destruction technologies rather than methods that concentrate or transfer the compounds.

Perma-Fix provides nuclear and mixed waste management services to hospitals, research institutions, federal agencies including the DOE, and the commercial nuclear industry. The company operates four nuclear waste treatment facilities nationwide.
