Company Description
Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) is a nuclear services company focused on the management and treatment of radioactive, nuclear and mixed waste, as well as specialized environmental and radiological services. According to company disclosures, it serves hospitals, research laboratories and institutions, U.S. federal agencies – including the U.S. Department of Energy (DOE) and the U.S. Department of Defense/Department of War (DOD/DOW) – and the commercial nuclear industry. Perma-Fix operates four nuclear waste treatment facilities and provides nuclear services at DOE, DOD/DOW and commercial sites across the United States.
Business Model and Segments
Perma-Fix reports two primary business segments: a Treatment segment and a Services segment. The Treatment segment provides nuclear, low-level radioactive, mixed, hazardous and non-hazardous waste treatment, processing and disposal services. This includes handling complex waste streams that require specialized technologies and regulatory approvals. The Services segment, which the company has identified as a major contributor to revenue, provides on-site waste management services to commercial and government customers, as well as technology-based services, construction, logistics and transportation services.
Across these segments, the company emphasizes project management, waste management, environmental restoration, decontamination and decommissioning, new build construction support, and radiological protection, safety and industrial hygiene capabilities for its clients.
Nuclear and Mixed Waste Management Focus
Perma-Fix describes itself as a provider of nuclear and mixed waste management services. Its nuclear waste services include the management and treatment of radioactive and mixed waste for a range of generators, such as medical and research institutions, federal agencies and commercial nuclear operators. The company highlights its role in treating Resource Conservation and Recovery Act (RCRA)-contaminated nuclear waste and byproduct material, and in addressing high-level waste streams associated with major federal cleanup missions, including work related to the Hanford site.
Through its Perma-Fix Northwest (PFNW) Mixed Waste Facility in Richland, Washington, the company operates under a Dangerous Mixed Waste Permit issued by the Washington Department of Ecology. A renewed permit for PFNW updates the original authorization to reflect current treatment units, infrastructure, safety systems and operating practices, and establishes detailed operating conditions for the treatment, storage and handling of hazardous and mixed radioactive materials. The renewed permit approximately triples PFNW’s permitted liquid mixed waste processing capacity, increasing authorized annual throughput from about 400,000 gallons to about 1.2 million gallons, supported by existing operational technology. It also authorizes PFNW to process up to 175,000 tons of waste annually through macroencapsulation, providing additional capacity and operational flexibility.
PFNW Facility and Hanford-Related Work
The PFNW facility’s renewed permit is described as a significant milestone for Perma-Fix’s nuclear services platform. The company notes that PFNW has continued to operate safely under its prior permit while the renewal process was underway and maintains separate radioactive material licenses from the Washington Department of Health. The permit renewal followed a public comment period and a Final Supplemental Environmental Impact Statement addressing waste streams, transportation logistics and treatment processes.
Perma-Fix states that PFNW is the only permitted mixed waste treatment facility located in close proximity to the Hanford site, which the company views as a competitive advantage given the regulatory, technical and operational barriers to entry in this market segment. The renewed permit is also positioned as supporting planned facility upgrades for upcoming West Area Tank retrieval milestones at Hanford and providing a regulatory foundation for potential future permit modifications associated with new technologies and expansion initiatives.
PFAS Destruction Technology and Environmental Services
In addition to nuclear and mixed waste activities, Perma-Fix has developed proprietary technology for the destruction of per- and polyfluoroalkyl substances (PFAS). The company describes its Perma-FAS™ process as a patent-pending, non-incineration PFAS destruction technology that operates in a closed system under relatively mild conditions. A 1,000-gallon PFAS destruction reactor at a Florida facility has been used to treat PFAS-contaminated waste, including aqueous film-forming foam (AFFF) and other high-concentration streams, and the company reports high levels of PFAS destruction across multiple carbon-fluorine chain types.
Perma-Fix has announced the expansion of its PFAS treatment capabilities beyond AFFF materials to include PFAS concentrate collected from leachate and wastewater. The technology has been adapted to treat these new waste streams, with commercial batches received for processing. The company emphasizes that its PFAS destruction process is intended to provide a permanent destruction pathway, contrasting it with storage, incineration or landfill disposal approaches that may not fully destroy PFAS compounds.
Partnerships and PFAS Foam Transition Solutions
Perma-Fix has entered into a joint distribution agreement with Enforcer One, LLC, a U.S.-based manufacturer of fluorine-free firefighting foams and compressed air foam systems. Under this collaboration, Perma-Fix offers Enforcer One’s FIREBULL fluorine-free foams and Enforcer compressed air foam systems to customers managing PFAS-impacted sites and preparing to replace legacy AFFF inventories. In return, Enforcer One promotes Perma-Fix’s Perma-FAS technology as a preferred PFAS destruction option.
The partnership is described as providing an end-to-end solution for PFAS foam transition: assessment and planning, removal and destruction of legacy AFFF stocks through Perma-FAS, and deployment of fluorine-free foam concentrates and equipment. Perma-Fix positions this approach as supporting customers’ environmental objectives and regulatory expectations while addressing long-term liability associated with PFAS-containing materials.
Federal, Commercial and International Engagement
Perma-Fix’s disclosures highlight activity across federal, commercial and international markets. The company reports that its Treatment segment has benefited from higher waste volumes and a growing backlog, including increased shipments from international and commercial customers. It also notes participation in major federal programs, such as support for the DOE’s Direct-Feed Low-Activity Waste (DFLAW) facility at Hanford, where Perma-Fix expects to support effluent treatment operations as volumes increase.
Within its Services segment, Perma-Fix pursues federal projects and has reported participation in contracts such as the Navy’s RADMAC III Indefinite Delivery, Indefinite Quantity (IDIQ) contract, which the company describes as aligned with its core competencies. The Services segment’s work includes environmental restoration, decontamination and decommissioning, and related field services at DOE, DOD and commercial facilities.
Labor, Governance and Regulatory Environment
The company’s regulatory and labor environment is reflected in its SEC filings. A wholly owned subsidiary, Perma-Fix Northwest Richland, Inc., has entered into a collective bargaining agreement with a local union representing production employees at the PFNW facility. The agreement addresses compensation, benefits and working conditions and is intended to support a skilled and stable workforce for waste treatment operations.
Perma-Fix has also reported amendments to its bylaws and actions related to its stock option plan in response to stockholder litigation and changes in Delaware corporate law. These include rescinding a previously approved amendment to its 2017 Stock Option Plan, proposing a new amendment subject to stockholder approval, and revising bylaw provisions regarding voting requirements, fee-shifting, and forum selection for certain stockholder claims. The company regularly holds annual meetings at which stockholders vote on director elections, auditor ratification and advisory compensation proposals.
PFAS Market Positioning and Technology Collaboration
In its public communications, Perma-Fix links its PFAS destruction technology to a broader PFAS remediation market that includes water separation technologies such as foam fractionation, reverse osmosis and resin-based systems. The company describes these separation methods as complementary to its destruction process, enabling PFAS to be concentrated and then destroyed. By collaborating with providers of these separation systems, Perma-Fix aims to offer a pathway from PFAS concentration to final destruction for large generators of PFAS waste, including municipalities, industrial clients and government agencies.
The company states that its PFAS destruction system is competitively priced relative to alternative methods and is designed to reduce long-term environmental liabilities by achieving comprehensive destruction of PFAS compounds. It reports that its first destruction unit has operated at commercial scale and that additional capacity is being developed through next-generation systems.
Corporate History and Leadership Recognition
Perma-Fix traces its origins to the work of its founder, Dr. Louis Centofanti, who established the company in the early 1990s with concepts focused on recycling hazardous waste into fuel and raw materials and developing in-drum treatment technologies for hazardous characteristic waste. Company communications describe Dr. Centofanti’s earlier work on processes to destroy polychlorinated biphenyls (PCBs) in oil and his role in advancing hazardous waste treatment and recycling methods.
Perma-Fix reports that Dr. Centofanti has been recognized with an Industry Innovation Award for his contributions to nuclear and hazardous waste treatment, including the development of Perma-FAS for PFAS destruction. The company credits his work with helping to define practices in modern hazardous and nuclear waste management.
