Claros Technologies, which last year raised $5.35 million in venture capital, has struck its first major agreement to scale its system to "capture, concentrate and destroy" PFAS chemicals from wastewater.

Minneapolis-based Claros said it has a partnership worth millions of dollars with Japan's Kureha Corp., a manufacturer of specialty chemicals and plastics for the advanced materials, agrochemicals, pharmaceuticals and wastewater-treatment industries.

"As a chemical company, Kureha has responsibility for mitigating the environmental impact of PFAS," Naomitsu Nishihata, president of Kureha America, said in a statement. "We seek to be socially responsible, accelerate innovation and expand our business portfolio. And Claros' comprehensive PFAS solution helps us meet each of those goals."

Claros CEO Michelle Bellanca, a former 3M technology executive recruited to commercialize Claros, called the agreement with Kureha a development that involves "substantial funds to accelerate our scale-up and commercialization of Claros' PFAS-destruction system."

"We have a partner who is ready to put our systems into real-world applications," Bellanca said. "We're confident that we are going to be very cost-competitive. For every million gallons of PFAS-polluted water treated, we concentrate that down with our sorbent to less than 10 gallons of PFAS concentrate to be destroyed."

On Tuesday, Claros will open a new headquarters and pilot plant in northeast Minneapolis.
