EPA’s SBIR Program Showcases Small Businesses Developing Technologies to Test and Treat PFAS

This April, EPA’s Small Business Innovation Research (SBIR) Program highlighted eight companies supported by the program that are developing technologies to detect, assess, and treat PFAS in the environment.

Of the eight companies, seven are pioneering technologies to remove PFAS from water, wastewater, and/or other liquids.  They utilize a variety of technological methods: Onvector LLC developed a plasma vortex reactor-based system; Claros Technologies, Inc. uses a photochemical method; and OxByEl Technologies, Inc.’s treatment relies on an electrochemical process.  One company, RemWell Inc., is working on a sonolysis reactor that will remediate PFAS in groundwater when placed in a horizontal well.  Another, BioLargo, Inc., uses an aqueous electrostatic concentrator to capture PFAS in a membrane for further treatment or disposal.

The only highlighted company that does not specialize in PFAS water treatment, Accurate Environmental Laboratories, developed a passive sampling method that determines levels of PFAS contamination in soils and sediments using diffusion.

Many of the small businesses report impressive efficacy, and some of their technologies are being applied in real-world situations.  Aquagga’s hydrothermal alkaline groundwater treatment process will soon be used for remediation projects at airports and air force bases.  Meanwhile, Cyclopure, Inc. is in the process of constructing full-scale regeneration and PFAS destruction facilities to administer its adsorbent-based PFAS water treatment.

Every year, EPA’s SBIR Program solicits technological proposals that address specific environmental topics.  Winning proposals are awarded contracts for “proof of concept” of the proposed technology and are eligible to apply for additional funding to further develop and commercialize the technology.  In five of the last six years, the program has included a PFAS-related topic in its batch of solicitations.
