Summary: To achieve a sustainable circular economy of polymers, the production of polymers must transition to recycled and biobased feedstock and achieve CO2 emission neutrality. Collecting and recycling polymers or utilizing biodegradable options at their end of life is crucial. Advances in polymer chemistry and applications, supported by computational material science, offer opportunities for designing polymers with recyclability and biodegradability. This Review explores the pathways for transforming the polymer industry towards a circular economy, taking into account scientific progress, regulatory frameworks, societal expectations, and economic factors.

Summary: The successful isoreticular functionalization of a zirconium MOC with tetrazole moiety resulted in a promising compound for gas separation applications. Adsorption isotherms, breakthrough experiments, and density functional theory calculations demonstrated its excellent C2H2/CO2 and C2H2/C2H4 separation performance. The design analogy between MOFs and highly stable MOCs could potentially lead to the synthesis of novel porous materials for challenging separation applications.

Summary: The commercial success of Li-ion batteries in the 1990s has led to environmental hazards from disposed batteries, raising questions about the greenness of current recycling technologies. Although industrially applied recycling technologies may have high overall efficiency, they often lack true circularity principles, which calls for a shift towards more sustainable and energy-efficient processes in the recycling of LIBs.

Summary: Researchers attempted to enhance the stability of aqueous-based Li-ion batteries using superconcentrated electrolytes, with LiF conformal layers reducing the solubility of LiF but proving unstable in aqueous environments. The study indicates that an artificially generated inorganic coating is not effective in preventing water reactivity in aqueous systems.

Summary: In this study, a sustainable microwave-assisted chemical recycling process was developed for recycling glass fiber reinforced polymer composite waste. The degradation of GFRP composites using hydrogen peroxide and acetic acid under microwave irradiation was investigated, achieving nearly complete degradation of epoxy. The recovered glass fibers showed high tensile strength and modulus, indicating the potential of the recycling process.

Summary: The development of bimetallic catalysts involves selecting appropriate metals and controlling their distribution on the support surface. Redox reactions can be used to deposit a second metal onto monometallic nanoparticles, creating core-shell nanoparticles with strong metal-metal interactions. This minireview describes the fundamentals and recent advances in the preparation of bimetallic catalysts using both direct redox reactions and the reduction of an intermediate reducing agent.

Summary: Industrial applications using recycled fibres or resins are still rare due to inferior performance to cost ratio. Mechanical frictional grinding is utilized to recover the reinforcement fibres, and incorporating all the recycled GFRP waste into a Fe-rich silicate slag shows remarkable flexural strength enhancement in the inorganic matrix.

Summary: Due to the high economic and environmental benefits, recycling metal chips, especially valuable alloys, has been considered. This study compares the sustainability of the Friction Stir Extrusion (FSE) technique with six different casting methods. Four sustainability indicators are evaluated and the FSE method achieves the highest levels in environmental, social, and mechanical indicators, with an overall sustainability score of 0.78. However, FSE still requires more attention in terms of economic feasibility.
