Rapid industrialization and development have led to a tremendous increase in the use of various types plastic commodities daily life. For past several years, pollution has become global issue, posing serious threat mankind. The primary issue with increasing is lack proper management which created huge havoc environment. From initial phase waste management, been discarded, recycled, downcycled, or dumped into landfills large proportion, causing extreme damage ecosystem. Conventionally, treated via thermal processes such as pyrolysis incineration plants require amount capital and, therefore, harms aim circular economy. Chemical upcycling gaining attention high-potential catalytic strategy convert plastics, polyethylene terephthalate, polyethylene, polystyrene, etc. fuels, functionalized polymers, other value-added chemicals having direct impact on affordability viability. In this review, we focused photocatalysis, electrocatalysis, photoelectrocatalysis effective efficient technologies. These approaches can lower dependence nonrenewable resources are more environmentally friendly contrast conventional approaches. This review elaborately discusses pros cons provides detailed overview potential renewable energy-driven for conversion wastes valuable fuels commodity chemicals, along challenges future directions emerging approach treatment.

Abstract Only a small proportion of global plastic waste is recycled, which most mechanically recycled into lower quality materials. The alternative, chemical recycling, enables renewed production pristine materials, but generally comes at high energy cost, particularly for processes like pyrolysis. This review focuses on light-driven approaches chemically recycling and upcycling waste, with emphasis reduced consumption selective transformations not achievable heat-driven methods. We focus challenging to recycle backbone structures composed mainly C‒C bonds, lack functional groups i.e., esters or amides, that facilitate e.g., by solvolysis. discuss the use light, either in conjunction heat drive depolymerization monomers via photocatalysis transform polymers valuable molecules. structural prerequisites these are outlined, highlighting their advantages as well limitations. conclude an outlook, addressing key challenges, opportunities, provide guidelines future photocatalyst (PC) development.

Abstract Plastics, renowned for their outstanding properties and extensive applications, assume an indispensable irreplaceable role in modern society. However, the ubiquitous consumption of plastic items has led to a growing accumulation waste. Unreasonable practices production, utilization, recycling plastics have substantial energy resource depletion environmental pollution. Herein, state‐of‐the‐art advancements lifecycle management are timely reviewed. Unlike typical reviews focused on recycling, this work presents in‐depth analysis entire plastics, covering whole process from synthesis, processing, ultimate disposal. The primary emphasis lies selecting judicious strategies methodologies at each stage mitigate adverse impact waste plastics. Specifically, article delineates rationale, methods, realized various stages through both physical chemical pathways. focal point is attainment optimal rates thereby alleviating ecological burden By scrutinizing aims furnish comprehensive solutions reducing pollution fostering sustainability across all facets

The reversion of vinyl polymers with carbon-carbon backbones to their monomers represents an ideal path alleviate the growing plastic waste stream. However, depolymerizing such stable materials remains a challenge, state-of-the-art methods relying on "designer" that are neither commercially produced nor suitable for real-world applications. In this work, we report main chain-initiated, visible light-triggered depolymerization directly applicable commercial containing undisclosed impurities (e.g., comonomers, additives, or dyes). By in situ generation chlorine radicals from solvent, near-quantitative (>98%) polymethacrylates could be achieved regardless synthetic route radical ionic polymerization), end group, and molecular weight (up 1.6 million daltons). possibility perform multigram-scale depolymerizations confer temporal control renders methodology versatile general recycling.
