Perma-Fix Environmental Services Provides Further Updates on Patent-Pending Process for Destruction of PFAS Compounds

Selects ProcessBarron for fabrication and assembly of the new commercial unit

Commercial unit on track to begin accepting waste in the second half of 2024

ATLANTA, June 12, 2024 (GLOBE NEWSWIRE) -- Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) today provided an update on its patent-pending new process, Perma-FAS®, for the destruction of per- and polyfluoroalkyl substances (PFAS), including design specifications and the Company’s selection of for the fabrication and assembly of its new Perma-FAS commercial unit. The system is a 1,000 gallon unit and is expected to be fully operational and accepting commercial waste for destruction by Q4 of this year.

Mark Duff, President and CEO of Perma-Fix, commented, “We are making rapid progress on the design and fabrication of our first Perma-FAS commercial unit, which we expect to be operational later this year. Towards this end, we are delighted to partner with ProcessBarron, which brings decades of experience constructing custom-engineered industrial solutions. We believe their track record and efficiency on such projects lends itself well to our strict timelines and safety standards, given the tremendous demand we have witnessed since first announcing our new system. Our relationship with ProcessBarron leverages their decades of experience in the application of proven industrial innovations to enhance performance of our initial system, while providing access to their team of engineers for system optimization. Following startup at our first facility, this relationship provides the ability to deploy additional units at our other facilities with increased efficiency, while reducing delivery schedules to support accelerated treatment activities to address nationwide PFAS markets over the next few years.”

Dr. Louis F. Centofanti, founder of the Company, Executive Vice President of Strategic Initiatives, and inventor of the technology, stated, “The latest regulatory and enforcement measures implemented by the U.S. Environmental Protection Agency (EPA), including the new CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act) Enforcement Discretion Policy, has created a renewed sense of urgency for waste generators. Our process is unlike traditional disposal methods for PFAS-contaminated materials, such as deep well injection and landfilling, which pose substantial environmental risks, including potential groundwater contamination. Ours will be the first known sealed, chemical destruction unit commercially operating in a fixed facility that can accept and destroy PFAS to acceptable levels in the U.S. We believe the unit will be able to achieve an impressive 99.9999% destruction level. We have been sharing information with the EPA, including plans to begin commercial operation of our novel treatment technology in the coming months, and look forward to supporting their near-term goals, as well as their long-term mission to rid our nation of these dangerous chemicals.”

The system uses a proprietary hydrolytic destruction process that is highly specific to PFAS compounds. It operates between 100-150 degrees Celsius and breaks down the carbon-fluorine chain, resulting in mineralization, with just calcium fluoride, water, and other non-hazardous organic byproducts that can be recovered and reused or resold.

Duff concluded: “I would also like to extend my gratitude to the team at Perma-Fix, including Dr. Centofanti, the chemists, and the engineers, who have all worked tirelessly to develop the commercial system in a timely and cost-effective manner. We had previously applied for patents and are planning additional patent applications surrounding this technology to address soils and filter media that we believe will provide us long-term protection on this groundbreaking intellectual property.”
