This sorting protocol describes a method to analyse post-consumer packaging waste samples in a relatively large detail. This detailed description of these lightweight packaging (LWP) wastes is required to provide compositional data which is required input data in material flow analysis. The protocol starts with describing the general requirements needed to study LWP in detail. Subsequently the method is described. This methodology is relative complex and laborious for LWP that contains plastic packages and is composed of three steps: sorting to main material by visual recognition, sorting into main polymer type with NIR and finally sorting into packaging type
