Per- and polyfluoroalkyl substances destruction

PFAS destruction companies in the data include Claros Technologies Inc., 374Water Inc., Revive Environmental and Perma fix Environmental Services. Claros develops photochemical destruction, while 374Water and Revive are associated with supercritical water oxidation. These firms illustrate different commercialization routes, from UV-based treatment to high-temperature processing of concentrated waste.

The startup set includes 11 companies, among them Claros Technologies Inc., Aquagga Inc. and AA Plasma. Claros is expanding its photochemical technology and manufacturing capacity; Aquagga develops hydrothermal alkaline treatment; and AA Plasma is linked to cold-plasma components. These examples represent distinct approaches, not a definitive ranking of commercial prospects.

Nanjing University, Chinese Academy of Sciences CAS and Tongji University are among the leading research organizations in the data. Their work spans photochemical degradation, electrochemical defluorination and thermal mineralization. Other active groups include Rice University, University of Aarhus and New Jersey Institute of Technology, with research covering catalysts, hydrothermal treatment and sonochemical reactors.

Recorded grants total $83,741,897 across 96 awards since 2020. This figure reflects the grant records associated with the field, not a complete measure of all public or private investment. The funding-round records include transactions that are not clearly attributable to PFAS destruction, so they should not be treated as a reliable sector investment total.

Claros Technologies Inc. leads the listed patent holders with 23 patents. Across the 24-month window, 138 patents were recorded, and patent activity declined 18.4% compared with the previous 12 months. The contrast between Claros’s portfolio and the overall trend suggests that individual companies may continue to build intellectual property even as aggregate patenting slows.

PFAS destruction is moving from laboratory research toward commercial treatment, but maturity varies by method and waste stream. The data records 686 publications in the last year, up 16.9%, alongside commercial activity from Claros Technologies, 374Water and Revive Environmental. Field trials and facility operations are important signals, but performance on complex feeds, energy use and verification of full defluorination remain central challenges.

Recent developments include conductive MXene membranes that couple osmotic concentration with electrochemical mineralization, reported in September 2026, and research on electrochemical and enzymatic fluoride recovery. In August 2026, 374Water and Arcadis received a Department of Defense Success Memo for AirSCWO destruction services. These advances point toward integrated treatment, resource recovery and deployment on real waste streams.

The main approaches are thermal treatment, supercritical water oxidation, electrochemical oxidation, photochemical destruction, plasma treatment, and cavitation or mechanochemistry. They differ in how they deliver energy and reactive conditions: heat and pressure suit concentrated wastes, while electrodes, light and plasma target chemical breakdown in liquid streams. Cavitation and mechanochemistry can address liquid or solid materials, but scale and energy efficiency remain concerns.

Applications include AFFF stockpiles, biosolids and sewage sludge, contaminated soil and groundwater, industrial waste streams, landfill leachate and water-treatment residuals. AFFF stockpiles are the largest listed application area, with 252 documents; biosolids and sewage sludge have 163. Treatment choice depends on the waste’s concentration, physical form and composition, as well as whether it can be transported to a destruction facility.

The United States leads the country breakdown with 3,846 documents, followed by China with 1,961. The United Kingdom, Germany and Japan are also active, with 962, 922 and 608 documents respectively. These figures indicate where activity is concentrated in the available records, but do not by themselves measure technology performance or commercial deployment.
