Abstract

The omnipresence of plastic products is undeniable in today¿s world and is often characterized by a short lifespan. Despite this fact, however, recycling rates are inferior. Strict requirements for mechanical recycling, which cannot be met by waste treatment plants, are one of the reasons. Therefore, chemical recycling, allowing more contaminated waste plastics to be recycled, improves the circularity. In this thesis, processing technologies of waste plastics for chemical recycling are examined. Conducting a literature and market review, developments, the state of the art and manufacturers of Near-infrared (NIR) sorting, dry and wet cleaning as well as wet density separation is described. Moreover, the applicability of selected processes is examined using large scale tests. Analyzing the results, specifically the purity and yield, the tested processes are compared and evaluated. The results of this thesis promote the applicability of waste plastics and hence contribute to a circular economy.
