In order to limit the anthropogenic climate change, humankind needs to reduce extracting fossil resources as soon as possible . Furthermore, the escalating global plastic waste crisis has propelled the urgent need for innovative solutions to reduce and manage plastic waste. The concept of a circular economy, which aims to minimize waste generation and maximize resource efficiency, holds potential in addressing this challenge . Within the waste hierarchy framework, after refusing, rethinking, reducing, reusing, repurposing and repairing, plastic recycling plays a pivotal role by transforming waste plastics into valuable resources . Since plastics are often recovered as mixed waste streams, the different types of plastic should be separated from one another into high purity polymer fractions in a first stage before an effective recycling can proceed with minimized downcycling .
