Open- and Closed-Loop Recycling of Polyesters and Post-Consumer Waste Under Industrially Relevant Conditions Using Bisguanidine Organocatalysts.

ABSTRACT: With the increasing demand for sustainable plastic materials, the implementation of a circular plastics economy starting from designing environmentally friendly polymers and including effective recycling strategies is of the utmost importance. The biobased and biodegradable polyester polylactide (PLA) is a promising candidate for a sustainable, circular plastics economy. Polyesters can be chemically recycled to obtain monomers or value-added chemicals following either a closed- or open-loop recycling approach. However, the requirements for catalysts applicable in post-consumer waste recycling are high: Besides a high activity, robustness and scalability of the catalyst are important factors. We studied highly active, robust bisguanidine organocatalysts for the depolymerization of the polye
