This Renovate project examines the extent to which solvent-stable nanofiltration and ultrafiltration membranes are able to contribute to higher-quality polymer recycling by selectively removing problematic molecules, such as REACH additives or colour. To this end, new types of membranes will be made and tested to remove the additives from solutions of recycled polymer mixtures. These membranes will be compared with commercially available membrane alternatives. Initial process schedules will be drawn up for the final processing of the obtained retentate and permeate streams. Minimal use of solvents and non-solvents, as well as minimal energy input during the process
whole process, will be pursued and the changed quality of the recycled polymers as a result will be quantified
