The purpose of this analysis is to evaluate the efficiency of different recycling procedures and the quality of the resulting recyclates. This dataset contains raw parallel plate rheology data of PP-recyclates from different recycling strategies. The content is: One Excel file containing parallel plate rheology data of PP recyclates after scCO2 recycling, reference samples and measurement protocol One Excel file containing parallel plate rheology of PP recyclates after solvent-based recycling, reference samples and measurement protocol One Excel file containing parallel plate rheology data of PP recyclates after upcycling, reference samples and measurement protocol One Readme file containing further information about the methodology and nomenclature This dataset was generated in the framework of PRecycling Horizon Europe project (101058670)
