5 startups preventing ‘without end chemical substances’


Like different poisonous air pollution that evokes outrage and regulation, per- and polyfluoroalkyl substances — PFAS for brief and sometimes called “without end chemical substances” as a result of they don’t degrade or dissolve over time — supply enterprise alternatives. Startups are speeding to wash up these immortal compounds, which seem in practically each physique and ecosystem the place they have been measured. 

PFAS pervade merchandise all through your private home — together with cookware, waterproof jackets and dental floss — and are tied to cancers, infertility and studying disabilities. 

In October, the U.S. Environmental Safety Company (EPA) finalized a rule requiring firms to report small releases of PFAS, following its spring proposal of requirements to trace a handful of the compounds in consuming water. Anti-PFAS insurance policies are on the books in 25 states, and the European Union and China are contemplating restrictions. 

What eliminates some 15,000 forms of chemical substances that appear to poison all the pieces, in all places, suddenly? Established remediation companies filter out PFAS from floor and water. Nonetheless, the PFAS is then incinerated or buried, re-joining groundwater and air. 

A brand new crop of firms seeks to demolish the chemical substances by unzipping the tight carbon and fluorine bonds that give PFAS their water-, grease- and fire-resistant properties. Right here’s a better take a look at 5 of them.

Revive Environmental

The problem: Many researchers are destroying PFAS in lab exams however haven’t ramped up. Columbus, Ohio, startup Revive Environmental says it’s scaling the destruction of all forms of PFAS.

The pitch: Revive’s cellular expertise destroys 99.99 % of short- and long-chain PFAS with intense stress and warmth. Inside its PFAS Annihilator delivery containers, supercritical water oxidation reduces the poisonous compounds to EPA-safe ranges for consuming water.

Tailwinds: Analysis nonprofit Batelle spun off Revive Environmental in January with Viking World Buyers. Revive CEO David Trueba, previously of Evoqua Water Applied sciences, calls the corporate “comfortably capitalized.” Revive is delivery six extra PFAS Annihilator items by January and plans to run 50 extra by 2025, he stated.

What’s distinctive: Revive shouldn’t be the one firm with cellular items dismantling PFAS, however it has reached business scale faster than most.


The problem: Aquagga says it could constantly clear up soil and water from industrial, authorities and municipal websites rife with PFAS.

The pitch: “We’re persistently top-ranked as one of many cleanest and most energy-efficient processes for PFAS destruction,” stated Aquagga CEO Nigel Sharp. The Tacoma, Washington, startup says it destroys greater than 99 % of PFAS in water by way of a patented hydrothermal alkaline remedy that produces no poisonous byproducts or air emissions.

Tailwinds: Launched in 2019, Aquagga has $8 million in funding. The general public profit company spun out of the College of Washington, the College of Alaska and the Colorado College of Mines. Aquagga gained an EPA PFAS-destruction problem in 2020.

What’s distinctive: Aquagga has two operational items, together with one funded by the EPA. A 3rd, funded by the Protection Superior Analysis Tasks Company, is because of come on-line subsequent spring.


The problem: Half of all PFAS are present in landfills, in keeping with Aclarity. Rain washes the chemical substances again into the water cycle. 

The pitch: Aclarity says it has the primary “full-scale” method to eradicate all forms of PFAS. Its modular techniques deal with landfill leachate constantly by way of electrochemical oxidation, which sends a present by way of a PFAS-laden resolution. Every 20-foot unit treats 24 gallons of landfill sludge per minute in a single cross, in keeping with CEO Julie Bliss Mullen.

Tailwinds: Mullen spun off Aclarity in 2017 from a PhD undertaking on the College of Massachusetts, Amherst. The Mansfield, Massachusetts, firm of 25 has raised $20.5 million, together with a Collection A $16 million in November. It gained Think about H2O’s City Water Problem final 12 months.

What’s distinctive: Aclarity seeks to put in everlasting websites within the U.S. and Europe. “The mixture of low power and low-cost elements…retains the fee considerably down,” Mullen stated.


The problem: Makes an attempt to take away and remove PFAS are sometimes energy- and chemical-intensive. Allonnia seeks to harness biology to zap the compounds at massive websites akin to landfills, airports and water remedy crops.

The pitch: “Nature is essentially the most elegant resolution to lots of in the present day’s most pressing environmental considerations and works in a round versus linear financial system,” CEO Nicole Richards stated. “For example, over time nature will evolve to interrupt down overseas supplies current together with man-made contaminants. That is the start line that Allonnia makes use of to develop options to interrupt down PFAS.”

Tailwinds: The Boston-based synbio startup has raised $90 million, together with a $30 million Collection A spherical in July. Allonnia sprang in 2020 out of the Ferment Consortium, an funding arm of biotech firm Gingo Bioworks, launched in 2008 by 5 MIT scientists. 

What’s distinctive: Allonnia says that though “blunt instruments” of bioremediation utilizing pure organisms are established, it hopes to dial up and pace up the pure processes by which micro organism or fungi eat chemical substances together with PFAS, minimizing using power and chemical substances. 

Claros Applied sciences

The problem: Claros Applied sciences seeks to shut the loop on PFAS in wastewater, landfill leachate and websites polluted by firefighting foams. 

The pitch: Claros says its mini-fridge-size system destroys 99.99 % of PFAS in water with ultraviolet mild and chemistry expertise that’s simple to retrofit into water filtration techniques. “Moreover, we go merely past ‘destruction’ of PFAS, and as a substitute use the time period ‘defluorination’ which refers back to the (destruction) of each carbon fluorine bond,” stated VP of Analysis and Improvement John Brockgreitens, describing a “inexperienced chemistry” method that leaves no poisonous byproducts.

Tailwinds: The Minneapolis-based firm of 25 raised a Collection A $5.5 million in 2021 and expects to shut a B spherical this 12 months. It grew out of analysis on the College of Minnesota funded by the EPA, the Facilities for Illness Management and the Division of Protection. CEO and co-founder Michelle Bellanca is a former world enterprise director at 3M.

What’s distinctive: Claros’s bottle-shaped “elemental destruction system” works at room temperature to destroy PFAS in batches of water inside a number of hours. The corporate is designing massive techniques to deal with 30 gallons of water per minute. Claros plans for a steady circulation cellular unit to run by the top of 2024.
