PESI PermaFix Environmental Services Inc

Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) announces the successful completion of the fabrication, installation, commissioning, and startup of its first full-scale commercial Perma-FAS system for PFAS (Per- and Polyfluoroalkyl Substances) destruction at the Company’s Perma-Fix Florida facility. This landmark development in Perma-Fix’s PFAS treatment technology marks a significant step forward in the safe, energy-efficient destruction of PFAS, commonly known as "forever chemicals."

The Perma-FAS system has successfully processed commercial PFAS-containing waste materials, beginning on October 28, with initial rapid turn analytical results showing an effective breakdown of the carbon-fluorine bond characteristics of PFAS at more than 99.99% after 6 hours of treatment. These results underscore the system's capacity to treat hazardous PFAS materials effectively, positioning Perma-Fix as a leader in addressing this environmental challenge with a unique closed-loop design that eliminates air emissions.

Designed for low-cost, eco-friendly PFAS treatment, the Perma-FAS unit operates at a peak temperature of 150°C under pressures below 100 PSI, allowing the processing of approximately 650 gallons of aqueous film-forming foam (AFFF) per treatment cycle. This sealed system, developed through extensive research and development at both bench and pilot scales, exemplifies Perma-Fix’s commitment to pioneering innovative solutions that minimize environmental impact.

Perma-Fix has already secured approximately 6,000 gallons of AFFF liquids to support ongoing operations and demonstration, with anticipated receipts of an additional 20,000 gallons in the coming months. This supply will support further engineering optimization of operating parameters, post-treatment separation, and enhancing system performance and efficiency for expanded commercial applications.

“This accomplishment reflects a corporate-wide effort to bring an operational and commercially viable unit online within a remarkably short timeline following laboratory validation,” stated Mark Duff, CEO of Perma-Fix. “Our team of scientists, engineers, and partners have collaborated to create an economically viable system that operates with limited energy and environmental impact. The units are also highly scalable and can be rapidly deployed at minimal cost, which allows us to ramp up capacity as needed in order to meet customer demand within the rapidly growing PFAS treatment market.”

“The operational parameters of our patent-pending technology set Perma-Fix apart from the competition,” added Dr. Lou Centofanti, Founder and Executive Vice President of Perma-Fix. “Our low-temperature, low-pressure approach, combined with streamlined engineering, offers an economically feasible and straightforward method for addressing PFAS contamination.”

First Commercial Perma-FAS System for PFAS Destruction

Looking ahead, Perma-Fix’s strategy for the Perma-FAS system includes continued treatment of PFAS liquids over the coming months and targeting engineering refinements to support larger-scale systems. The next-generation units aim to increase capacity, incorporate recycling features to reduce costs, and enhance deployment efficiencies. By mid-2025, the Company expects to advance this technology into pilot-scale applications for soil, biosolids, and filter media, broadening the reach of Perma-Fix’s PFAS destruction capabilities.

With over 30 years of experience in the environmental sector, Perma-Fix provides a trusted infrastructure to meet the growing demand for PFAS destruction while managing customer risks and liabilities associated with hazardous materials.
