Scale-up of next-generation biobased textile fiber - from demonstration to full scale production

The project focuses on developing and scaling up the TreeToTextile (TTT) technology, which produces sustainable fibers as an alternative to cotton and viscose. Addressing the environmental impact of textiles, TTT aims to deliver low-impact fibers requiring less water, chemicals, and energy. Cotton and viscose are resource-intensive and harmful, while TTT offers a cleaner process to enable “Better Fibers to All” meaning available and affordable textiles to the whole society. The project aim is to generate data for decision-making and minimize the risk of investment when scaling up the Swedish demo plant to the first industrial-scale Flagship facility, a step important both for the Swedish and European bioeconomy.  

Key goals include comparing continuous vs. batch dissolution, testing industrial washing and drying concepts, and optimising processes for efficiency. Five work packages structure the work: scalable dissolution, washing, and drying; applying Life Cycle Assessment (LCA) for sustainable scale-up; and managing communication, alignment, and risks. The project partners—TreeToTextile, Lenzing AG, and Lenzing Ltd.—contribute expertise, equipment, and significant in-kind support. Ultimately, the project aims to establish a scalable, sustainable fiber production process that meets market demand while reducing the textile industry’s environmental footprint.
