Abstract

The project aims to develop novel bio-based technologies for the selective separation and recovery of synthetic textile fibers for recycling in the textile industry. This is based on the use of enzymes that can metabolize or degrade highly specific macromolecules. While the degradation of cellulose by enzymes has been studied in nature for 150 years and has also been used for decades for engineering applications, enzymes that are also able to metabolize synthetic fibers have been developed quite recently. Due to the high specificity of these enzymes, it is possible to gradually "extract" valuable components from textile residual flows of multi-material composition and / or to recycle certain fibers by systematic and gentle separation of unwanted fibers.
