Scarcity of resources, environmental pollution, and global warming, call to rethink new ways to work towards a sustainable economy. The solution is a Circular Economy, in which waste is used as a valuable source of raw materials. As far as plastics are concerned, the EU has already set the recycling targets: plastic waste should be reusable or recyclable in a cost-effective manner and thus become valuable secondary raw materials. The prerequisite for a wide range of possible uses of the recyclates is that the starting material is sorted and free of impurities.
