Material Recycling of Plastics Waste. The recycling of plastics waste comprises of two main steps, viz. waste preparation and melt processing. Depending on the quality of the waste input and the desired product, the various recycling processes differ considerably in these two steps. For mixed and contaminated plastics wastes, processes are available which, with minimum preparation, process the melt into thick‐walled products. Better defined plastics wastes on the other hand are treated with greater investment in preparation and are generally processed with extrusion into granules for normal plastic processes. Preparation includes shredding, washing and drying, sorting, and agglomeration.
