The advancement and modernization of industries have provided numerous benefits to human life including diversification of manufacturing a wide range of products made from plastic materials, thereby leading to the generation of huge quantities of plastic waste. Owing to the increasing issues related with plastic waste, recycling methods have attracted much interest. Recycling not only protects the environment and resources for future generations but also reduces energy consumption and greenhouse gas emissions. A wide range of valuable products including char, oil, fuels, sorbent materials, and chemicals can be obtained through different techniques. This Review highlights various sustainable research avenues and potential routes to reduce the environmental impact of plastic waste based on both traditional and potential approaches for its utilization.

“…Therefore, an alternative for this is the utilization of plastic waste by liquefaction, biological treatment, and pyrolysis ( Al-Salem et al, 2010 ; Sharma et al, 2015 ; Lopez et al, 2017 ). Pyrolysis of plastic waste has been explored to convert plastic waste into fuel at high temperatures, while using a catalyst enhances the degradation and reduces the energy requirements ( Yuan et al, 2014 ; Jin et al, 2019 ; Gopinath et al, 2020 ). In very recent studies, pyrolysis has also been performed in the presence of hydrogen to minimize the extent of coking and the fractional yield of unsaturated compounds ( Bai et al, 2019 ).…”

Recent Advances in Catalysis Based on Transition Metals Supported on Zeolites

This article reviews the current state and development of thermal catalytic processes using transition metals (TM) supported on zeolites (TM/Z), as well as the contribution of theoretical studies to understand the details of the catalytic processes. Structural features inherent to zeolites, and their corresponding properties such as ion exchange capacity, stable and very regular microporosity, the ability to create additional mesoporosity, as well as the potential chemical modification of their properties by isomorphic substitution of tetrahedral atoms in the crystal framework, make them unique catalyst carriers. New methods that modify zeolites, including sequential ion exchange, multiple isomorphic substitution, and the creation of hierarchically porous structures both during synthesis and in subsequent stages of post-synthetic processing, continue to be discovered. TM/Z catalysts can be applied to new processes such as CO2 capture/conversion, methane activation/conversion, selective catalytic NOx reduction (SCR-deNOx), catalytic depolymerization, biomass conversion and H2 production/storage.

“…By increasing the petroleum prices, recycling of PET plastic bottles leads to higher profits for the manufacturers compared with the situation in which they use the virgin materials (Jacobs and Subramanian 2012). In fact, due to the environmental effects, recycling of the plastic bottles for reusing them in different industries has attracted a considerable attention in recent years (Doan et al 2020;Gopinath et al 2020). As an example, PET plastic bottles can be collected, cleaned, and recycled to be reused in textile industry (Majumdar et al 2020).…”

This study considers a sustainable supply chain including the collector, cleaner, and recycler for recycling of PET plastic bottles and reusing them in textile industry. In the market, some suppliers of textile industry purchase cleaned and non-fragmented bottles and then they fragment them, whereas others prefer to buy recycled materials (i.e., cleaned and fragmented bottles). The collector collects used plastic bottles. To meet demand of the recycled materials, the collector transfers a portion of the collected bottles to the recycler and then the recycler cleans and fragments them. Furthermore, the collector cleans another portion of the collected bottles himself or via a cleaner to meet demand of the cleaned and non-fragmented bottles. In this setting, two different structures are established for transferring the cleaned bottles to suppliers. Under the first structure, the collector cleans the collected bottles through the cleaner by giving a share of the profit to him, while he is equipped with the bottles cleaning technology by paying a setup cost under the second structure. Moreover, the game-theoretic models are developed including Nash, Stackelberg, and Centralized to make decisions under two considered structures.
