Topic of this thesis is a feasibility study on the processability of post-consumer plastics from the Shredder Light Fraction from a technical and an economical point of view. It especially focuses on the fractions of waste plastics of the ARN Recycling plant in Tiel (Netherlands) within a density class lower than 1.1 g/cm³. Further content of this thesis is an extensive fraction analysis of these fractions and, based on its results, systematic classification and separation experiments utilizing properties like “density”, “electrical conductivity” and “settling velocity”. Using these thereby achieved findings several concepts for an extension of the existing processing plant were developed and then compared based on an economical assessment.
