H&M wants to make clothing from CO2 using this startup’s tech

The fashion industry faces significant environmental challenges, producing more carbon emissions than international flights and maritime shipping combined, while generating vast textile waste. In response, some companies are exploring innovative materials and sustainable production methods. One such startup, Rubi, recently secured $7.5 million in funding to develop a demonstration-scale cellulosic production system that uses carbon dioxide as its primary raw material. This enzyme-based technology, distinct from other approaches that rely on engineered bacteria or chemical catalysts, converts CO2 into textile-grade cellulose suitable for lyocell or viscose production. Rubi has already engaged 15 pilot partners, including major brands like H&M, Patagonia, and Walmart, and has non-binding off-take agreements exceeding $60 million. Rubi’s process involves a “cascade” of enzymes operating in an aqueous solution, where the addition of CO2 rapidly produces cellulose within shipping container-sized reactors. The company employs AI and machine learning to enhance enzyme performance and aims to transition to continuous production in the future.
