Perma-Fix Environmental Services Expands PFAS Treatment Capabilities to New Waste Streams

Leverages Advanced Technology and Industry Collaboration to Capitalize on Expanding Multi-Billion Dollar PFAS Remediation Market

ATLANTA, Aug. 04, 2025 (GLOBE NEWSWIRE) -- Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) today announced the expansion of its proprietary PFAS (per- and polyfluoroalkyl substances) treatment technology to address a broader range of contaminated waste streams beyond AFFF (aqueous film-forming foam) materials including PFAS concentrate collected from leachate and waste water. This milestone follows successful trials and marks a significant step in the Company’s mission to provide comprehensive, sustainable solutions for PFAS remediation.

Building on past successes, where the Perma-Fix process demonstrated the ability to destroy PFAS in high-concentration commercial waste, the next-generation treatment technology has been adapted to treat leachate and wastewater concentrate. In June, the Company received the first commercial batch of these new waste streams and will begin treatment imminently in the full-scale reactor, with plans to treat these materials in future units as well. The technology is designed with flexibility in mind, allowing for potential future deployment at customer sites. The current focus remains on centralized treatment at the Company’s facilities.

The market for water separation technologies—including foam fractionation systems, reverse osmosis systems, and resin-based systems—is experiencing rapid growth as organizations seek to concentrate PFAS from large volumes of contaminated water. These separation technologies are highly complementary to the Company’s destruction technology process. By collaborating with leading providers of these separation solutions, the Company delivers an efficient and cost-effective pathway for the final destruction of PFAS concentrate, addressing a critical gap in the remediation value chain and enabling customers to meet stringent regulatory standards while controlling costs.

The Perma-Fix system is competitively priced compared to alternative destruction methods. In addition to cost savings, this approach helps address the potential for legacy environmental liabilities that can arise from storage, incineration, or landfill disposal that do not provide for full destruction. By providing comprehensive destruction of PFAS compounds, the solution reduces customers’ long-term liability exposure and supports compliance with evolving regulatory expectations—a benefit consistently recognized by clients and partners in past projects.

The PFAS remediation market continues to grow, driven by increasing regulatory scrutiny and the U.S Environmental Protection Agency’s (EPA) ongoing consideration of hazardous waste classification for PFAS. Industry estimates suggest that the addressable market for PFAS treatment in the U.S. alone could reach several billion dollars annually, as tens of millions of gallons of contaminated water and soil require urgent remediation. The Company’s scalable solution, combined with collaborations with companies specializing in water separation technologies, positions Perma-Fix to serve large generators of PFAS waste including municipalities, industrial clients, and government agencies—by providing a comprehensive approach from separation to final destruction.

Dr. Lou Centofanti, Executive Vice President of Perma-Fix, commented, “We are excited to expand our PFAS treatment capabilities and address new waste streams, further strengthening our leadership in this critical sector. Our technology’s proven performance in destroying PFAS , combined with our commitment to innovation, enables us to meet the growing needs of our customers and support a cleaner environment. By working closely with water separation technology providers—including foam fractionation, reverse osmosis, and resin systems—we are able to offer a comprehensive, efficient, and cost-effective solution for the destruction of PFAS concentrate. Importantly, our approach not only delivers cost savings but also minimizes the risk of future environmental liabilities for our clients by ensuring comprehensive, permanent destruction of these persistent chemicals.”
