Kemira is a Finnish water-treatment company that partnered with Cambridge-based CuspAI to design new materials for removing PFAS from drinking water, announced May 2026. Using generative AI, they searched roughly 300 trillion possible structures and returned 5,000 novel metal-organic frameworks for three priority PFAS molecules — compressing years of experimental chemistry into six months, the first commercial partnership to apply generative AI end-to-end to PFAS material design.
