Closing the Loop on Forever Chemicals

How can PFAS contamination be permanently destroyed without disrupting industries that depend on forever chemicals?

You wake up in the morning and reach for your phone. You drive to work. You board a plane. You pick up a prescription or watch someone you love recover because a medical device did what it was designed to do.

Each of these moments feels unrelated. But per- and polyfluoroalkyl substances (PFAS) thread through each one.

PFAS have built modern life, behind the panels and under the wiring. Five hundred miles of PFAS-coated wire keep a commercial aircraft from catching fire. Heart stents and IV lines depend on them. Semiconductor fabs rely on them to etch the chips that run everything from a phone to a power grid. Pharmaceutical manufacturing uses them to deliver medications that work as intended. Strip PFAS from everyday life and halt the availability of products essential to modern life.

That is the chemistry at the center of this story. PFAS are in the water. They persist, accumulate and earn the nickname ‘forever chemicals’ because once they enter the environment, they stay.

For decades, public conversation has treated this as a binary. Ban PFAS or accept the contamination. Two unsatisfying answers to a question that deserves a better one.
Claros Technologies is building a better answer, the third way.

ClarosTechUV^™ destroys long-, short- and ultra-short-chain PFAS compounds in aqueous waste streams at rates of hundreds of gallons per minute, with 99.99 percent effectiveness using a proprietary reactor system. What this means is that PFAS chemistries are broken apart and mineralized down to their elemental components, primarily fluoride ions, rather than captured and moved elsewhere. Permanent destruction is now possible.

“The story is not simply about a new technology. It is about an inflection point where the PFAS challenge begins to shift from a problem that must be managed to one that can realistically be solved,” says John Brockgreitens, Ph.D., VP of Product Development and Co-founder of Claros Technologies.

Industries that depend on PFAS no longer have to choose between using them and protecting the environment around their facilities. Regulators no longer have to weigh economic disruption against environmental responsibility.

What Capture Could Never Solve

Why are traditional PFAS capture and disposal methods insufficient for long-term remediation?

Conventional PFAS treatment uses activated carbon filters, reverse osmosis and ion-exchange resins to capture PFAS contaminants. Reverse osmosis systems pull PFAS compounds from a water stream, concentrate them elsewhere and generate reject brine. Activated carbon systems produce spent media. Ion-exchange systems exhaust their resins. Each approach leaves something behind.

Then comes the awkward question. ‘What do you do with what is left behind?’

Operators have three options, none of them good. Incineration burns waste, imposing its own costs and emissions burden. Landfill disposal pushes contamination underground, where it leaches over time. Trucking the waste elsewhere hands the problem to another facility. Each route ends with the same compounds existing somewhere, waiting.
“There are very few solutions right now in the marketplace that will destroy all PFAS species (long, short and ultra-short) at a very high flow level and that is where we uniquely fit. We can take a customer’s water stream, analyze it, determine which PFAS compounds are present and with our proprietary UV system, process the water and destroy the PFAS,” says Brockgreitens.

ClarosTechUV inverts the treatment logic. PFAS gets destroyed earlier in the process, before it accumulates in filtration media. Volumes of contaminated waste shrink, disposal costs drop and liability is resolved at source.

System placement adapts to each application. Claros analyzes the waste stream first, then positions the system at the point in the treatment train where destruction performance peaks and operating cost bottoms out.

Why UV Was Counted Out

How does Claros Technologies use advanced UV reactor engineering to destroy PFAS compounds at scale?

UV technology has been a workhorse in water treatment for decades, primarily in disinfection. When early researchers attempted to apply conventional UV processes to PFAS destruction, the results were disappointing. Industry concluded UV was not up to the job. Capital flowed toward alternatives such as supercritical water oxidation, hydrothermal alkaline treatment and plasma systems. Each works, but demands high capital, significant energy and complex operations.

Claros looked at the same data and reached a different conclusion. Early failures reflected the limits of early designs; UV itself was never the ceiling. Reactor architecture rebuilt from first principles, paired with in-house-developed proprietary chemistry, enabled ClarosTechUV to achieve industrial-scale defluorination that earlier UV systems could not.

The carbon-fluorine bond is the strongest single bond in organic chemistry and it is the reason PFAS persist in the environment. Breaking it at scale is the engineering achievement at the heart of the platform.

“ClarosTechUV may share the UV label with earlier UV systems, but the underlying engineering is fundamentally novel and different,” says Brockgreitens.

The Lab Behind the Reactor

Why are PFAS analytics, regulatory compliance and scalable destruction infrastructure becoming critical for industry?

ClarosLabs^™ is the analytical division driving Claros’s work. Since its founding in 2020, the lab has processed over 40,000 samples using targeted testing, non-targeted analysis and molecular fingerprinting techniques, including high-resolution mass spectrometry. The work identifies which PFAS compounds are present in a given waste stream and how they behave under treatment conditions.

PFAS is a class of more than 10,000 compounds. Each behaves differently and requires different conditions to break apart. Without rigorous analytical capability, destruction technology runs blind.

“We became PFAS detection experts so we could become PFAS destruction experts,” says Brockgreitens.

Legal counsel working with and advising Industrial customers facing legal scrutiny may be able to retain Claros to perform Attorney-Client Privileged Analytical Assessments.

The Regulation Tide

Regulatory pressure on PFAS is rising worldwide. State-level action in the U.S. is moving faster than federal rulemaking, while Europe’s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) framework is pushing toward broad restrictions. Direction is unmistakable. Limits are getting stricter, more compounds are being brought under coverage and compliance windows are shrinking.

Industries most exposed cannot simply walk away from PFAS. Semiconductors, pharmaceuticals, specialty chemicals, advanced textiles and packaging rely on PFAS for performance properties that no current substitute can match.

What they need is a way to keep using them without releasing them.

“For many industrial users, the issue is no longer whether PFAS regulation is coming, but how to manage emissions responsibly while those chemistries remain in use,” says Brockgreitens.

Older treatment technologies were built around long-chain compounds, the legacy molecules that drew the first wave of regulatory focus. Smaller variants slip through capture systems and increasingly draw their own restrictions. Any technology that cannot address them is on a clock. ClarosTechUV destroys all three categories, including ultra-short-chain compounds, which remain the hardest to break apart.

Capital invested in treatment infrastructure today has to survive the next regulatory tightening. Spending millions on a system that handles only currently regulated compounds creates stranded assets the moment the rulebook expands. Operators want infrastructure that holds up across multiple compliance cycles. Claros gives them that runway and lowers their ongoing exposure.

Proof in the Field

How is Claros Technologies scaling PFAS destruction for industrial, municipal and environmental applications?

Field results validate the platform. Claros works with Daikin America on industrial-scale PFAS destruction. A recent pilot proved ≥99.99 percent PFAS destruction in groundwater from a 3M-related remediation site, anchoring the underlying science. Customers across pharmaceutical, semiconductor and other industrial sectors are running ClarosTechUV.

Municipalities and environmental agencies are part of the conversation as well.

“Drinking water standards are tightening and remediation budgets are expanding. The same destruction platform serves public and private operators alike,” says Brockgreitens.

Claros delivers regulatory compliance, reduces operating costs and engineers treatment infrastructure to absorb the next regulatory shift without another round of capital spending.

Leadership reinforces the platform’s credibility. Co-founder and CEO Michelle Bellanca spent years as a senior executive at 3M. Her team brings deep operational backgrounds in industries that manufacture or depend on PFAS. That collective experience informs how Claros approaches risk, regulation and adoption inside complex industrial organizations.

The Scale of What Comes Next

PFAS remediation represents a market of hundreds of billions of dollars worldwide, spanning industrial wastewater, municipal systems and drinking water infrastructure. Industrial wastewater is where ClarosTechUV operates today. Groundwater, municipal water and drinking water may be the next steps.

Modularity is the near-term engineering focus. Greater modularity means broader commercial deployment, faster integration into diverse facility configurations and lower implementation friction for new customers.

That combination of commercial validation, scientific depth and regulatory engagement earned Claros Technologies recognition as Sustainable PFAS Destruction Solutions of the Year by Chemical Industry Review.

The Promise

The PFAS conversation has carried a particular weight for years. A sense that the modern world built itself on a chemistry it could not undo. A feeling that environmental responsibility and industrial progress would have to fight it out, with one of them losing.

Claros Technologies is dismantling that premise.

“Our technology allows both sides to move beyond the idea that addressing PFAS requires choosing between environmental protection and economic progress,” says Brockgreitens.

Phones still get made, planes still fly, Fabs still etch semiconductors. Industries that need PFAS keep using them. The water leaving the facility is clean.

Forever chemicals are no longer forever. That sentence was, until recently, wishful thinking. It is becoming engineering.
