Published: Jan. 1, 2023

Diversification of polymer waste recycling is one the solutions to improve current environmental scenario. Upcycling a promising strategy for converting into molecular intermediates and high-value products. Although catalytic transformations small molecules have been actively discussed, methods characteristics upcycling new materials not yet addressed. Recently, functionalisation wastes (polyethylene terephthalate bottles, polypropylene surgical masks, rubber tires, etc.) their conversion with enhanced functionality proposed as an appealing alternative dealing recycling/treatment. In this review, term 'functional upcycling' introduced designate any method post-polymerisation modification or surface without considerable chain destruction produce upcycled material added value. This review explores functional detailed consideration most common polymers, i.e., polystyrene, poly(methyl methacrylate), polyethylene, polypropylene, polyurethane, polyethylene terephthalate, polyvinyl chloride, polycarbonate, rubber. We discuss composition plastic waste, reactivity, available physical/chemical agents modification, interconnection between properties application. To date, successfully applied adsorbents (including CO2), catalysts, electrode energy storage sensing, demonstrating high Importantly, reviewed reports indicated that specific performance generally comparable higher than similar prepared from virgin feedstock. All these advantages promote diversification approach against postprocessing employed waste. Finally, identify limitations suggest future scope research each polymer, we comparatively analysed aspects those chemical mechanical recycling, considering resource costs, toxicity used chemicals, footprint, value product.

SUMMARYThis narrative review and meta-analysis summarizes a broad evidence base on the benefits-and also practicalities, disbenefits, harms personal, sociocultural environmental impacts-of masks masking. Our synthesis of from over 100 published reviews selected primary studies, including re-analyzing contested meta-analyses key clinical trials, produced seven findings. First, there is strong consistent for airborne transmission severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) other pathogens. Second, are, if correctly consistently worn, effective in reducing diseases show dose-response effect. Third, respirators are significantly more than medical or cloth masks. Fourth, mask mandates overall, community Fifth, important symbols; non-adherence to masking sometimes linked political ideological beliefs widely circulated mis- disinformation. Sixth, while much that not generally harmful general population, may be relatively contraindicated individuals with certain conditions, who require exemption. Furthermore, groups (notably D/deaf people) disadvantaged when others masked. Finally, risks environment single-use respirators. We propose an agenda future research, improved characterization situations which should recommended mandated; attention comfort acceptability; generalized disability-focused communication support settings where worn; development testing novel materials designs filtration, breathability, impact.
