  • The textile industry’s reliance on synthetic dyes is an important source of greenhouse gas emissions. Here the authors describe a process involving sustainable solvents that allows the extraction, purification, and reuse of dyes, as well as the recycling of dye-free fabrics.

  • Oxidative catalytic depolymerization of polystyrene (PS) can produce benzoic acid, but the annual consumption of benzoic acid is ~40 times lower than PS, so benzoic acid should be converted to higher-volume chemicals for the process to be viable. Here, the authors report a hybrid chemical and biological process that uses PS as feedstock for production of adipic acid, a high-volume co-monomer for nylon 6,6, via benzoic acid.

  • A pore-modulated pyrolysis reactor that enables catalyst-free and energy-efficient upcycling of plastic waste is demonstrated. The graded-pore structure imposes molecular-weight-dependent transport barriers, establishing a gating effect that enhances product selectivity and yields aviation fuel precursor (C8–C18) with high efficiency.

  • The controllable conversion of plastic wastes to products with tailored molar mass would facilitate waste valorization but remains challenging. This study presents a catalyst- and hydrogen-free temperature-gradient thermolysis strategy to achieve this goal.

  • Bio-based polyethylene-like materials with tunable thermal and mechanical properties have been synthesized from plant-derived diols using an acceptorless dehydrogenative polymerization strategy. Now it has been shown that this atom-economical and mass-economical approach employing non-precious metal catalysts enables closed-loop recycling and advances sustainable solutions for the circular plastic economy.
