The purpose of the project is to study reactor design as well as rheological and warming conditions to streamline and optimize resource utilization in the processing of textile waste with an inorganic ionic liquid. This must be done with a kneading reactor that is capable of processing materials with very high viscosity under a wide range of process conditions. In this way, we can contribute to better utilization of a currently very underutilized and abundant waste, as well as a more sustainable society.
