In the last few years reports have become more and more frequent that plastics and their constituents (plasticiser, flame retardant, etc.) are an environmental risk. Nevertheless, an industrialised society without this material would no longer be conceivable, since the fields of application are very diverse. One possible approach to counteract this growing problem is the implementation of a comprehensive and functioning collection system that allows recycling of post-consumer plastics. A comparison between countries shows that only a small portion of the plastic quantities put into circulation are collected and recycled. Compared to the collected quantities, the output-related recycling rate, which is the actual material recycling, is currently still modest.The investigations of the present research project “Plastic Reborn” deal, on the one hand, with the identification and, on the other hand, with the depiction of the discharge paths of polyolefin-rich waste streams in Austrian waste management (waste flow diagram). In addition, exploitation potentials for the output fractions generated from the wet-mechanical processing are determined. The waste flow diagram shows that despite a well-functioning separate collection a large potential of unused polyolefin is still available for recycling. The first separation tests with a wet-mechanical processing have shown that the polyolefin potential of the waste streams can be separated. These excess quantities of plastics can be a significant contribution to the implementation of the European circular economy strategy.
