The technology features a new processing agent used during the pretreatment phase of the chemical recycling process, which helps improve the quality of the recycled polyester fiber that is derived from clothing containing PU elastomer fiber. In addition to removing the PU elastomer fiber, the new technology eliminates foreign materials such as dyes, and helps to omit the decolorization process of polyester fiber. Teijin Frontier has been conducting tests of this new technology since October 2022 for practical use.

Guided by THINK ECO® environmental strategy, Teijin Frontier is striving to achieve ambitious sustainability goals by developing advanced technologies that support recycling and enhance the value of environmentally responsible materials. As part of its initiative focused on polyester fiber, the company is working with the supply chain to establish a comprehensive ecosystem spanning apparel collection, sorting and recycling. Teijin Frontier is confident that its new foreign material removal method can help expand the scope of fiber-to-fiber recycling and contribute to a zero-waste societ
