Abstract
AbstractChemical recycling of plastic wastes can be a useful complement to mechanical recycling to achieve the required plastics recycling rates and to establish a circular economy that is climate neutral and resource‐efficient. Different mixed plastic wastes that are subject to future recycling efforts are studied under uniform conditions of intermediate pyrolysis characterized by a medium heating rate and pyrolysis temperature. Product distributions and selected product properties are determined, and process mass and energy balances are derived. Product yields and compositions are highly dependent on the waste pyrolyzed. The results show that pyrolysis is a suitable process to recover chemical feedstock from various complex mixed plastic wastes.

European plastics converters’ demand was 50.7 million tons in 2019 [1]
Lightweight packaging sorting residues (LWP-SR), commercial waste from construction waste sorting (CW), external thermal insulation composite systems based on extruded polystyrene (ETICS), automotive shredder residue from the mechanical processing of shredder light fraction (ASR), and residue from the mechanical recycling of electrical and electronic waste (WEEE) were investigated
The depending on the characteristic composition of the feedpyrolysis condensates are collected at the respective constock
Summary
European plastics converters’ demand was 50.7 million tons in 2019 [1]. Packaging and construction are the largest enduse markets, followed by automotive and electrical, and electronic applications. The demand for common plastics and typical applications are listed in Tab. 1. Polyolefin plastics account for more than half of the demand. In Germany, about 12 million tons of plastics were consumed in 2019 and about 6 million tons of plastic waste were collected. Utilization is reflected in the volume of waste quite differently. For typically short-life packaging plastics, more than 95 % of the consumed mass was recovered in waste. In the case of construction and automotive plastics with longer product life cycles, consumption and waste volume diverge significantly. Large amounts of plastics are still in use and will remain relevant for future recycling concepts
