Impact55 2026 runner-up: Cellexcel

Impact55 runner-up, Cellexcel impressed the judges for the second year in a row with its technology that strengthens natural materials by making them more water-resistant. Biomaterials such as natural plant fibres are more sustainable than plastics or fibreglass but often struggle in harsh environments. Cellexcel’s molecular modification process enables them to perform like high-carbon alternatives while retaining their sustainable benefits.
