New clean-tech solutions are being developed and piloted across the United States to permanently destroy PFAS (per- and polyfluoroalkyl substances), widely known as “forever chemicals,” which have contaminated water and soil worldwide. These groundbreaking technologies offer hope for tackling an environmental and public health crisis linked to a class of chemicals notorious for their persistence, toxicity, and widespread industrial use.

The Growing PFAS Crisis: What Are ‘Forever Chemicals’?
PFAS are synthetic chemicals used since the 1950s in a broad range of consumer and industrial products, including waterproof clothing, non-stick cookware, food packaging, cosmetics, and firefighting foams. Their unique carbon-fluorine chemical bonds render them highly resistant to degradation, enabling their presence to persist in the environment for decades – hence the nickname “forever chemicals.”
Scientific research has increasingly connected PFAS exposure to adverse health effects, such as elevated risks of certain cancers, thyroid disorders, immune system impairment, and reproductive issues. According to the US Environmental Protection Agency (EPA), PFAS contamination has been detected in the drinking water of approximately 110 million Americans as of 2024.
Dr. Jane Hathaway, an environmental toxicologist at the University of Michigan, notes, “The stubborn nature of PFAS poses a unique challenge because conventional water treatment techniques cannot fully remove or destroy them, leaving communities at risk.”
From Detection to Destruction: Overcoming PFAS Waste Management Challenges
Current methods to handle PFAS contamination typically involve detecting and concentrating the chemicals via filtration and other treatment systems. However, the concentrated waste streams containing PFAS are traditionally disposed of through long-term storage, incineration, or landfilling. These approaches carry significant drawbacks: storage risks environmental leakage, incineration may produce toxic emissions if incomplete, and landfill disposal risks groundwater contamination.
Parker Bovée, an analyst at Cleantech Group who tracks innovations in environmental cleanup, emphasizes the need for “destruction technologies” that can break down PFAS at a molecular level. “There’s a lot of destruction that needs to be done,” he said, highlighting growing market demand for methods to eliminate PFAS instead of simply isolating and storing the chemicals.
Innovative Technologies on the Frontline of PFAS Destruction
Several cutting-edge technologies are making headway into commercial viability, promising to disrupt existing disposal paradigms by breaking the durable carbon-fluorine bonds that define PFAS.
Electrochemical Oxidation (EO)
One of the most advanced options is electrochemical oxidation. This process involves passing an electrical current through PFAS-contaminated water via specialized electrodes, leading to the breakdown of PFAS molecules without requiring high temperatures or pressures.
Mark Ralph, CEO of Axine Water Technologies, a Canadian startup pioneering EO solutions, explained, “While energy intensive, EO is easier to operate and integrate into existing water treatment facilities compared to some other methods.” Axine’s first commercial-scale unit is operational at an automotive parts manufacturer in Michigan, with plans to expand to additional sites.
Supercritical Water Oxidation (SCWO)
Another promising technique is Supercritical Water Oxidation, which subjects water to extreme heat and pressure, transforming it into a supercritical fluid a unique state that enables rapid and complete PFAS destruction.
Chris Gannon, CEO of 374Water based in North Carolina, highlighted SCWO’s versatility: “Our technology can handle both liquid and solid PFAS wastes, including plastics if ground up, making it suitable for diverse waste streams.” SCWO installations are being tested at the City of Orlando’s largest wastewater treatment plant, where officials aim to preempt future regulations governing PFAS in sewage sludge.
The process requires complex reactors and regular maintenance, making operational costs a consideration. However, pre-concentrating PFAS waste prior to treatment can improve cost-effectiveness.
Emerging Alternatives: HALT and Plasma Technologies
Hydrothermal alkaline treatment (HALT) and plasma-based processes are also nearing readiness. HALT uses high temperature, pressure, and alkaline chemicals to degrade PFAS, while plasma-based techniques employ ionized gases to break down the molecules. Aquagga, a California-based company specializing in HALT, recently completed a Department of Defense (DoD) demonstration project destroying PFAS-containing firefighting foam.
Regulatory Pressure and Market Dynamics Fuel Innovation
The US legal landscape has become increasingly stringent. The EPA has scheduled regulatory limits for two PFAS compounds in drinking water to take effect in 2031, reflecting bipartisan recognition of the chemical threat. Legal actions have triggered massive settlements from chemical manufacturers such as 3M, driving demand for remediation technologies.
“There’s a large and growing market for PFAS destruction,” Bovée confirmed. “While the US is currently leading, other regions are beginning to explore this space.” In the UK, for instance, water companies have received funding from Ofwat, the government regulator, to investigate PFAS destruction options, with Severn Trent Water spearheading technology assessments.
The European Union has similarly imposed legal limits for PFAS in drinking water, effective from 2026, laying the groundwork for broader international regulatory alignment.
Military Contamination and Industrial Waste: Testing Grounds for New Technologies
The US Department of Defense faces a significant PFAS contamination challenge at over 700 known or suspected sites nationwide, primarily linked to the use of PFAS-based firefighting foams. Until recently, military efforts to manage PFAS pollution were hampered by technical and regulatory uncertainties.
Alan Oyler, Special Projects Manager for Public Works at Orlando, explained, “We’re testing new tech proactively, as PFAS levels in sludge are expected to be regulated soon. Technologies like SCWO offer hope for scalable solutions.”
The DoD has partnered with startups such as Aquagga and 374Water to pilot destruction methods, aiming to remove stockpiled firefighting foams and remediate soil and groundwater contamination.
Beyond the military, PFAS waste streams are poised to expand with the scaling up of US domestic semiconductor manufacturing, where PFAS are heavily used. Gannon predicts, “We can destroy PFAS associated with chip production, representing a crucial future market.”
Balancing Promise with Caution: Byproducts and Environmental Safety
Despite technological advances, experts warn about potential byproducts produced during PFAS destruction that require thorough assessment.
Jay Meegoda, professor of civil and environmental engineering at New Jersey Institute of Technology, pointed out, “Electrochemical oxidation can generate corrosive hydrogen fluoride vapors. Each process demands comprehensive analysis of inputs, outputs, and any toxic intermediates.”
Companies assert that their systems adequately address or avoid harmful degradation products, but environmental watchdogs call for independent verification and transparent reporting to ensure public safety.
Looking Ahead: Scaling Up Solutions for Global Impact
As PFAS contamination continues to attract global regulatory attention and public concern, clean-tech companies are racing to commercialize robust, scalable destruction technologies. Pilot projects spanning industrial manufacturers, municipal utilities, and the military are critical proving grounds for demonstrating cost, reliability, and environmental performance.
Bovée of Cleantech Group concluded, “With regulatory frameworks tightening worldwide and legal liabilities mounting, the PFAS destruction market is poised for rapid growth over the next decade. Success here will define how effectively society manages a ubiquitous, persistent pollutant that has long challenged environmental protection.”
The path toward a future free of “forever chemicals” now lies in harnessing scientific innovation to break what was once thought unbreakable.
