Today, there is a developmental gap present in the textile recycling industry between collecting and sorting solutions on one side and processing approaches for turning textile waste into new fibers on the other side. LIST Kneader Technology as a process platform is addressing this gap by enabling and accelerating chemical textile recycling processes across various basic materials.

The need for textile recycling solutions is widely known. While plastic recycling is discussed in many conferences driven by EU regulations, they refer predominantly to bottles and packaging and are often silent about textile recycling – although a large share of PET is used for fibers and not for bottles. While industrial solutions for collecting and sorting textile waste have been developed over the past years, lots of processing approaches for turning textile waste into new fibers are currently being pursued on a research level. These processes can become challenging when they need to be upscaled to an economically viable plant. One reason being the specific rheological behavior of textile scraps and fiber waste featuring solid and liquid characteristics as well as their large volumes. Therefore, process intensification is a key factor for successful scale-up. The presentation will give an overview over a range of different recycling approaches for various polymers including synthetic and natural fibers as well as textile blends classifying them by processing technological criteria. The presentation will further inform researchers and developers about the general processing technological capabilities of the LIST high viscosity and solids processing platform and how it can be used in textile processing. Since the 1960-ies, LIST technology has been a development platform well-known in the chemical industry for scalable polymer synthesis and difficult thermal separation applications due to its capability to handle phase changing processes passing liquid, sticky, and solid stages in a single continuously operated equipment. The same capabilities can be used for advanced polymer recycling processes – including textile recycling. The presentation will be held by Leonard Sylla, R&D Engineer and Judith Günther, R&D Engineer.
