Start-up Fairbrics is using CO2 emitted by industry to replace polyester made with fossil fuels. Founded in 2019, this green chemistry start-up has developed an innovative process that turns captured CO2 into textile fibers. It serves as a concrete example of how the circular economy can contribute to decarbonization. During the two years that it spent at Accelair, Air Liquide’s deep tech start-up accelerator, Fairbrics developed its technology thanks to the laboratories at its disposal and the technical and safety expertise of the Group’s R&D teams. Thanks to this support, Fairbrics was able to launch and raise nearly €10 million in 2020 and 2021 to transition to an industrial scale. In 2022, following a second round of financing of more than €20 million, the start-up announced the construction of a pilot plant in Antwerp that will produce 1,000 T-shirts per day from the CO2 emissions of factories in the industrial zone.
