Claros Technologies, Inc. has secured $55 million in Series B financing to accelerate its proprietary ClarosTechUV™ PFAS Destruction System, furthering PFAS destruction technology. , a Minneapolis-based specialist in environmental remediation, has secured $55 million in Series B financing. Announced on July 28, 2026, the funding aims to accelerate the global commercialisation of its proprietary ClarosTechUV™ PFAS Destruction System and expand its ClarosLabs™ analytical operations, furthering PFAS destruction technology.
Treehouse Family Capital LLC led the investment round, with significant participation from Daikin America, Inc., Veralto, Bush Foundation, Nord Asset Management, and Saint Paul & Minnesota Foundation, alongside existing investors.
Advancing PFAS destruction technology innovation
This capital injection positions Claros Technologies to meet escalating global demand for permanent solutions to per- and polyfluoroalkyl substances (PFAS) contamination. The company will use the funds to strengthen manufacturing capabilities, enhance operational reach, and expand its footprint across North America, Europe, and Asia. It also plans to invest further in research and development.
The core of Claros Technologies’ offering lies in its ClarosTechUV™ PFAS Destruction System. This proprietary UV-photochemical process is engineered for the permanent eradication of PFAS compounds, representing a significant shift from traditional methods that merely transfer contaminants between waste streams.
The system effectively destroys long-chain, short-chain, and ultra-short-chain PFAS compounds. It consistently achieves greater than 99.99% destruction rates across these diverse chemical structures. This high efficacy is crucial for addressing the persistent nature of these “forever chemicals.”
The ClarosTechUV system’s engineering principles
ClarosTechUV™ is designed for real-world industrial and environmental applications. Its field-ready, affordable, and high-flow characteristics enable scalable deployment across various challenging scenarios. This engineering approach makes it suitable for widespread adoption.
In December 2025, Claros Technologies partnered with Daikin America, Inc. to conduct one of the world’s largest industrial PFAS destruction demonstrations. The system successfully treated over 170,000 gallons (approximately 640,000 litres) of industrial process water at Daikin America’s facility in Decatur, Alabama. This pilot achieved over 99.99% destruction of targeted PFAS species at high flow rates.
Earlier in April 2026, the technology showed similar performance in large-scale groundwater remediation projects. It demonstrated ≥99.99% destruction of targeted PFAS compounds from concentrate derived from approximately one million gallons (3.8 million litres) of groundwater. Such results underscore the system’s versatility.
Doug Parker, PhD, Vice President of Claros Technologies, notes that the system destroys all currently regulated PFAS compounds. It also tackles many compounds likely to face regulation soon. The technology has successfully treated wastewater with PFAS concentrations ranging from hundreds of micrograms per litre to single-digit milligrams per litre, showcasing its adaptability to diverse contamination levels.
Precision analytical capabilities through ClarosLabs
Beyond destruction, Claros Technologies integrates comprehensive analytical services through its ClarosLabs™ division. This ISO/IEC 17025:2017 accredited laboratory provides essential support for industries grappling with PFAS issues. These services ensure accurate measurement and assessment.
ClarosLabs™ focuses on PFAS detection, quantification, and exposure assessment. This holistic approach means clients not only have access to permanent destruction technology but also reliable data on the presence and concentration of these harmful chemicals. This combination is vital for demonstrating compliance and validating remediation efforts.
Meeting tightening global environmental standards
The growing stringency of environmental regulations worldwide is a primary driver behind the demand for advanced PFAS destruction technology. Governments are intensifying efforts to mitigate the widespread environmental and public health risks associated with PFAS.
European regulators continue to advance restrictions under the proposed REACH framework, aiming to curb the use and release of PFAS. Simultaneously, U.S. federal and state agencies are expanding drinking water rules, industrial discharge requirements, and remediation programmes. These legislative actions create a clear mandate for effective solutions.
Claros Technologies’ CEO and Co-Founder Michelle Bellanca affirms that the company has moved beyond technology validation to commercial success. She points to successful industrial and environmental projects as proof of the platform’s effectiveness at scale. This commercial readiness aligns with urgent regulatory needs.
David Hendrixson, Executive Vice President of Daikin America, Inc., commented in December 2025 on their pilot project. He stated, “Over the past year, we’ve proven that complete PFAS destruction at industrial scale is not theoretical — it’s happening now.” His remarks highlight the practical, immediate impact of Claros’ solutions.
Strategic investment in manufacturing and global reach
The $55 million Series B funding will significantly bolster Claros Technologies’ strategic objectives. A core focus is to expand manufacturing capacity and enhance operational capabilities. This will allow the company to scale up production of its ClarosTechUV™ systems and increase service delivery.
The investment will support commercial deployments across key industrial regions. This includes significant expansion efforts throughout North America, Europe, and Asia. Such a global footprint is essential for meeting the widespread nature of PFAS contamination.
Claros Technologies also plans strategic hiring initiatives across its engineering and commercial operations. Strengthening these teams will improve application development, bolster customer support capabilities, and accelerate market adoption among industrial clients. The company aims to ensure its technology can reach all industries that need it.
Founded in 2018 in Minneapolis, Claros Technologies has specifically targeted industries facing critical challenges with PFAS management. These include semiconductor manufacturing, aerospace, pharmaceuticals, and healthcare. These sectors often rely on PFAS for specialised applications but now need viable alternatives for chemical handling and waste treatment.
The broader impact of permanent PFAS solutions
The investment in Claros Technologies underscores a critical paradigm shift in environmental management: moving from merely containing PFAS to permanently destroying it. For manufacturing and engineering professionals, this represents a significant step towards sustainable industrial practices and compliance certainty.
Industries worldwide are searching for reliable destruction technology combined with accurate laboratory analysis to meet increasingly strict compliance obligations. Claros’ integrated platform addresses both needs, offering a comprehensive solution for complex contamination problems. This holistic approach simplifies a challenging regulatory landscape for many businesses.
The ability to destroy all regulated and soon-to-be-regulated PFAS compounds provides considerable foresight for industrial planning. It offers companies a pathway to future-proof their operations against evolving environmental mandates. This proactive stance helps maintain operational licenses and avoids costly future remediation efforts.
For industries in Africa, grappling with their own industrialisation and associated environmental challenges, the deployment of such advanced technologies could be transformative. While not explicitly mentioned in Claros’ immediate expansion plans, the global push for PFAS remediation suggests that effective, scalable solutions like ClarosTechUV™ will eventually become essential across all continents. This would support cleaner industrial growth and protect public health in emerging economies.
Ultimately, the successful commercialisation of PFAS destruction technology ensures that critical industries can continue their operations while upholding environmental stewardship. This investment in Claros Technologies is not just about financial growth; it’s about enabling a cleaner, safer future for industrial processes worldwide. The company’s focus on permanent eradication rather than temporary management sets a new benchmark for environmental responsibility.
