Photocatalytic Conversion of Plastic Waste: From Photodegradation to Photosynthesis

Advanced Energy Materials, Год журнала: 2022, Номер 12(22)

Опубликована: Апрель 21, 2022

Abstract Plastic waste remains a global challenge due to the massive amounts being produced without satisfactory treatment technologies for recycling and upcycling. Photocatalytic processes are emerging as green promising approaches upcycle plastics into value‐added products under mild conditions using sunlight energy source. In this review, recent advances in plastic conversion through photocatalysis have been comprehensively summarized. Special emphasis is placed on photocatalytic mechanism selective CC CH bond transformations of access fuels, chemicals, materials. Finally, challenges perspectives establishing new paradigm toward sustainable circular economy also put forward.

Review of polymer technologies for improving the recycling and upcycling efficiency of plastic waste

Chemosphere, Год журнала: 2023, Номер 320, С. 138089 - 138089

Опубликована: Фев. 6, 2023

Human society has become increasingly reliant on plastic because it allows for convenient and sanitary living. However, recycling rates are currently low, which means that the majority of waste ends up in landfills or ocean. Increasing upcycling is a critical strategy addressing issues caused by pollution, but there several technical limitations to overcome. This article reviews advancements polymer technology aim improve efficiency waste. In food packaging, natural polymers with excellent gas barrier properties self-cleaning abilities have been introduced as environmentally friendly alternatives existing materials reduce food-derived contamination. Upcycling valorization approaches emerged transform into high-value-added products. Recent development recyclable high-performance plastics include design super engineering thermoplastics chemical bonds thermosets make them biodegradable. Further research needed develop more cost-effective scalable technologies address pollution problem through sustainable upcycling.
