The ongoing COVID-19 pandemic is leading to an increase of the global production plastics since use personal protective equipment (PPEs, i.e. gloves, gowns, masks, packaging items), has become mandatory prevent spread virus. Plastic breaks down into micro/nano particles due physical or chemical biological actions environment. Due small dimensions, ubiquitous and persistent nature, plastic represent a significant threat ecosystems can entry food chains. Among polymers used for PPEs, polystyrene less studied regarding its eco-geno-toxicity. This study aims investigate acute, chronic subchronic effects microplastic beads (PS-MP, size 1.0 μm) on three freshwater species, alga Raphidocelis subcapitata, rotifer Brachionus calyciflorus, crustacean Ceriodaphnia dubia benthic ostracod Heterocypris incongruens. Furthermore, potential genotoxicity ROS PS-MP were also determined in C. dubia. Results revealed that acute occurred at concentrations order dozens mg/L B. calyciflorus hundreds H. Regarding long-term toxicity, increasing with EC50s units (C. dubia), (B. calyciflorus) thousands (R. subcapitata) μg/L observed. Both chronic/sub daphnids more sensitive than ostracods. Moreover, when neonates exposed PS-MP, alterations genetic material as well occurred, starting from μg/L, probably inflammatory responses. At last, risk quotient (RQ) measure posed by PS-MPs environment, was calculated obtaining value 7.2, higher threshold 1.

During the COVID-19 pandemic, extensive use of face masks and protective personal equipment (PPE) kits has led to increasing degree microplastic pollution (MP) because they are typically discarded into seas, rivers, streets, other parts environment. Currently, a negative impact on environment high-level fragmentation. Typically, MP can be detected by various techniques, such as microscopic analysis, density separation, Fourier transform infrared spectrometry. However, there limited studies disposable PPE kits. A wide range marine species ingest MPs in form fibers fragments, which directly affect human health; thus, more research development needed effect health. This article provides perspective origin distribution waterbodies (e.g., ponds, lakes, seas) wastewater treatment plants, reviews possible remediation related excessive disposal aquatic environments.

One of the most important aspects supply chain management (SCM) is recovery network (RN), which covers all activities associated with return products (such as collection, recovery, repair, recycling, and waste disposal). Our goal in this paper to provide a new mathematical model sustainable end‐of‐life (SEOLM) during COVID‐19 pandemic for readers. The suggested (RNM) can explain trade‐offs between economic (minimizing total costs), environmental bad impacts), social impacts) great lockdown. A RN be designed hygienic design when taking environmental, economic, considerations into account. It proposes guidelines managers scholars on how address (RND) challenges through article approach. scalarization approach multi‐objective mixed‐integer programming (MOMIP) problem weighted sum method. validation presented related Pareto frontier has been illustrated by case study numerical example.

Abstract This paper aims to introduce a framework measure the sustainable performance of supply chain (SC) during COVID-19 pandemic. The SC stakeholders in this investigation are Suppliers, Production / Remanufacturing Refurbishing Centers (Factories), Collection Distribution Centers, Recycling Landfill and Customers. suggested (SSC) measurement included three pillars with 23 indicators. To evaluate overall sustainability understudy, composite index has been developed that combines all indicators reflect SC. Four steps involved creating index:1) measuring value indicators, 2) weighing 3) Using normalization technique, 4) Evaluating SSC indicator. real case Iran is selected as an illustrative case. Our research contributions are: We novelty indicator better show economic, environmental, social tradeoffs pandemic lockdowns. have found measured negative positive impacts on aspects Based achieved data study, numerical example represented explain how calculate index. main contribution development epidemic.

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.
