This dataset corresponds to the paper: “The impact of collection portfolio expansion on key performance indicators of the Dutch recycling system for Post-Consumer Plastic Packaging Waste, a comparison between 2014 and 2017” (2019). The dataset includes two folders, one for the MFA model for 2017 and one for the model results of both the 2014 and 2017 model. Folder 1 (Tables A to I) contains the model description. Tables A, B and C list general input data for the model, such as gross collected amounts and the sorting distribution. Tables D, E, F and G relates to compositional data of separately collected post-consumer plastic packaging waste (PCPPW). In tables D and E the measured average compositions of collected materials and sorted products are listed (input STAN). The output of STAN for collected PCPPW and sorted products made therefrom, are listed in tables F and G. Tables H and I list the compositional data of PCPPW that was mechanically recovered from mixed municipal solid waste (MSW). In table H the ...
