The International Comparison work package, part of the Netherlands Institute for Sustainable Packaging’s plastic chain project, is intended to determine where five other European nations stand with regards to closing their plastic packaging materials chain, both in terms of raw materials and in an economic sense. The main objective of this work package is to derive starting points for interventions from the analyses that can be used in the Netherlands to further close the plastics chain. The countries have been selected to ensure that the three types of collection and recycling systems that are currently common in the EU are all featured: a comprehensive collection structure, a selective collection structure and a collection structure that relies on manual sorting by “hand pickers.” The focus of this analysis is on domestic plastic packaging waste, unless explicitly stated otherwise.
