Summary: The study demonstrates an efficient strategy for degrading diverse waste polyesters at low temperature and pressure, utilizing a quinaldine-based Ru complex for initial transesterification and hydrogenation. The catalysts can be hydrogenated to an active species, which shows strong viability and high activity in protic solvent. Methanol plays a crucial role in promoting reaction efficiency throughout the process.

Summary: The recycling of polystyrene waste is a challenging issue. Researchers have found that using visible light and uranium-catalyzed reaction can efficiently convert polystyrene into acetophenone, regardless of the molecular weight, polydispersity, or form, and acetophenone can be used as an additive to improve the reaction yield in some cases.

Summary: An iron(II)-catalyzed polymerization of arylallenes has been reported, generating high molecular weight polymers at room temperature. The polymer structures and chain lengths of various monomers were determined using NMR, DSC, and GPC analysis. Mechanistically, it is proposed that chain growth occurs through a reactive Fe(III) species, rather than the formation of an iron(II) hydride in situ.

Summary: Shaping a sustainable future is closely tied to advanced plastic recycling technologies. Low global recycling rates result in the incineration or landfill disposal of post-consumer plastics, causing severe environmental risks and a loss of chemical resources. Recent breakthroughs in photocatalytic methods offer a solution by converting polymers into valuable organic molecules under environmentally benign conditions.

Summary: Lignin is the largest renewable source of aromatics globally, but the majority is still burned as low-value fuel, with only a small percentage used for high-value chemicals. Understanding lignin depolymerization and its application in biorefineries is a key area for future research and development.

Summary: Efficient chemical depolymerization of waste polyolefins to monomers is still a challenge, but it can help prevent further waste accumulation and generate economic benefits. A recent study by Conk et al. successfully converted polyethylene (PE) into propylene using a tandem catalysis approach, with yields as high as 87%. This proof of concept opens up possibilities for future research on catalyst optimization, process design, and compatibility with contaminated and multi-polymer waste streams.

Summary: This report discusses the promising method of utilizing plastic waste through chemical recycling, specifically hydrogenative depolymerization using a Mn pincer complex catalyst. The key to success lies in the combination of the catalyst with elevated temperatures and appropriate solvents to ensure sufficient solubility of the polymers. The process successfully depolymerizes a wide range of polyurethane samples, releasing polyetherols and diaminotoluene in high yields.
