... Despite the substantial growth of the plastics industry, the rate of reuse and recycling of end-of-life plastics is shockingly low; an example would be the European market, as less than 30% of the 25.8 million tons of plastic waste generated annually is readily available for collection to be recycled^[2]. Consequently, the remaining majority of the plastic waste is still landfilled or incinerated, which imposes a negative impact on the environment and raises a significant economic cost. Therefore, the preference for addressing plastic waste must be strictly implemented to be recycling, especially for the instances where re-using is considered unfeasible...

... In this work, we propose a membrane-based separation and purification platform for common waste plastics (e.g. PC, HIPS, PLA) upon their dissolution in various organic solvent systems. For that, a systematic screening of polymer/additive/solvent couplings was conducted via Hansen solubility methodology, to maximize the polymer recovery via optimizing the dissolution kinetics. Moreover, organic solvent ultrafiltration (OSUF) was explored to test the downstream purification performance of commercial ceramic UF membranes for the separation of high-performance plastics and industrially-relevant additives via simulated mixed-waste solutions. It was shown that...
