PFAS destruction has a new address: inside a working fluoropolymer plant.
On October 1, 2026, Claros Technologies and Daikin America announced a commercial agreement for full-scale deployment of the ClarosTechUV PFAS destruction system at Daikin’s manufacturing facility in Decatur, Alabama. According to the companies, the system will be integrated directly into Daikin’s operations as a continuously operating, permanent installation, not a trial unit parked beside the process.
The deal follows a staged path. The partnership began with a pilot demonstration, moved into commercial optimization and has now reached permanent deployment. That sequence is exactly what the destruction market has been waiting to see: a large manufacturer taking a technology through each gate and then signing for the long term.
Claros chief executive and co-founder Michelle Bellanca called it “the defining commercial achievement in Claros’ history” and said permanent PFAS destruction “has crossed the threshold from scientific achievement to commercial reality.”
A Pilot Became a Purchase Order
Most PFAS destruction technologies are still being judged on test data. Bench results, demonstration skids and short campaigns are useful, but they do not answer the question that industrial buyers care about most: will it run, every day, on real process water, without disrupting production?
A long-term commercial agreement from a manufacturer of Daikin America’s size is a strong answer. The company, established in 1991, makes high-performance materials for semiconductor, medical device, aerospace and clean energy markets. Its decision to build destruction into the plant rather than rely only on capture and off-site disposal signals real confidence in operating performance.
Daikin America chief executive Yuichi Hashikawa framed the agreement as a continuation of the relationship and of the company’s commitment to innovation and environmental stewardship.
That matters to every other technology developer, too.
Each credible full-scale reference lowers the perceived risk for the next buyer, whether the destruction method is UV-based, electrochemical, plasma or supercritical water oxidation.
Short Chains Are Where the Claim Gets Interesting
Claros says ClarosTechUV destroys 99.99% of target PFAS species across long, short and ultra-short chains, including TFA. That last point deserves attention.
Short and ultra-short compounds are the hard end of the problem. They are highly mobile, they break through adsorbents faster than legacy long-chain compounds, and trifluoroacetic acid in particular has drawn growing scrutiny from regulators and researchers. A treatment train that handles PFOA and PFOS well but lets the smallest molecules pass is increasingly an incomplete answer.
If a destruction system can deal with the full chain-length range at industrial scale, operators gain a simpler compliance story. Fewer residual streams, fewer handoffs and fewer questions about where the leftover fraction ends up.
Measurement Is Built Into the Deal
The agreement pairs destruction with continuous analytical testing through ClarosLabs, the company’s analytical division, which holds ISO/IEC 17025:2017 accreditation. The companies describe the result as an integrated platform for treatment, measurement and operational validation.
That design choice is as important as the reactor itself. Industrial operators do not only need PFAS destroyed. They need defensible data showing it was destroyed, on a schedule that regulators, auditors, customers and insurers can rely on.
Bundling verification with treatment is a model other vendors are likely to copy. For buyers evaluating on-site systems, the practical checklist is getting clearer:
- Destruction performance across long, short and ultra-short chains, not just headline compounds
- Continuous operation on real process water at production flow rates
- Accredited, ongoing analytical verification of results
- Clear handling of any residuals or byproducts
- A staged route from pilot to permanent installation
- Room to replicate the system at other sites
Federal Guidance Is Pointing the Same Direction
The timing fits the policy signals. In its 2026 Interim Guidance on the Destruction and Disposal of PFAS, released April 23, 2026, EPA encourages “technologies that target and destroy PFAS and that minimize PFAS release,” and notes that landfilling could result in higher PFAS releases to the environment than the agency previously thought in 2024.
The guidance does not set requirements, and it focuses mainly on established options such as hazardous waste landfills, underground injection and thermal treatment. But EPA also acknowledges that companies and researchers are developing and testing new destruction technologies, offers a framework for evaluating them, and has committed to updating the guidance every year instead of every three years.
Annual updates mean field data from deployments like Decatur can feed into federal thinking much faster than before.
The Next Test Is Replication
According to the companies, the agreement sets up a long-term strategic relationship that reaches beyond one installation, with plans to evaluate further ClarosTechUV applications across Daikin’s global operations. Claros, founded in 2018 in Minneapolis, also targets groundwater, municipal wastewater and data center water.
Which raises the questions the market will watch through 2027.
Can a second and third Daikin site follow on similar terms?
Can the same platform win a utility or a remediation contract outside manufacturing?
For investors, a repeatable industrial reference is what turns a promising destruction company into a scalable one. For other manufacturers, the Decatur project offers a template: treat the PFAS at the source, measure it continuously, and remove the downstream liability before it leaves the site.
Capture moved PFAS around. On-site destruction is how the industry starts closing the loop.
