The Cover Feature illustrates the bisguanidine organocatalyst-driven recycling of common polyesters, polylactide (PLA), polyethylene terephthalate (PET), and polycaprolactone (PCL). Three catalysts were evaluated in their ability to depolymerize PLA, with the most active demonstrating remarkable versatility and robustness in cascade recycling of polymer mixes and the valorization of post-consumer PET waste, thus highlighting a sustainable pathway toward a circular plastics economy.
