This report outlines a strategy to produce solutions for the collection, sorting and reprocessing of commercial and industrial (C&I) plastic waste in urban environments. The aim is to provide guidance for urban and regional policymakers and researchers to, first, understand the current situation regarding the production of C&I plastic waste in their regions. Second, guidance is given on how to engage with the regional actors of the plastic waste value chain and learn about their attitudes. Based on this knowledge, the report provides suggestions for potential material testing and test collections of plastic waste, which would result in new logistics scenarios and new circular value chains that could be created.
