The funding round, led by Treehouse Family Capital LLC, includes participation from strategic players such as Daikin America, Veralto, and the Bush Foundation. This influx of capital will bolster Claros' manufacturing capacity and facilitate the expansion of its mobile laboratory, ClarosLabs. The company aims to meet rising demand from utilities, government agencies, and manufacturers in the semiconductor and pharmaceutical sectors that require reliable, permanent solutions for per- and polyfluoroalkyl substances.
Claros Technologies Secures $55 Million to Scale PFAS Destruction
Minneapolis-based Claros Technologies has closed a $55 million Series B financing round to scale its proprietary PFAS destruction systems globally. The capital injection arrives as the company transitions from experimental breakthroughs to industrial-scale deployment, targeting a market increasingly driven by tightening environmental regulations and the urgent need to eliminate persistent chemicals.
Claros’ commercial momentum follows a series of technical validations, including a 2025 demonstration where its ClarosTechUV system achieved over 99.99% destruction of PFAS compounds in industrial process water. More recently, in April 2026, the company successfully processed one million gallons of groundwater, proving the technology's effectiveness in complex environmental remediation. CEO Michelle Bellanca emphasized that these results validate the system's ability to operate cost-effectively at scale, providing a necessary tool for organizations navigating evolving global compliance mandates. As regulators in both the U.S. and Europe move toward stricter industrial discharge and drinking water standards, the company is positioning its integrated platform—combining destruction tech with specialized analytical services—to become a standard utility for environmental stewardship.
