“…Debnath et al (2018) have introduced a method of understanding sustainability in a generalized manner from the principles of LCA. Similarly, Ghosh et al (2018) have reported a generalized discussion on sustainability from a systems approach, eliminating the ambiguity of the silo approach. In this study, the authors have followed the same pattern, using the LCT approach.…”

e-Waste is generated at the staggering rate of 6.1 kg per person. In 2016, 44.7 million tonnes was generated globally, and the amount is estimated to reach 52 million tonnes annually by 2021. The management of this huge quantity of e-waste is a major problem across the world, primarily in developing countries. An effective e-waste management system is linked to the sustainability of e-waste processing plants, and currently it is plagued with different supply chain network (SCN) issues. To address the issues and challenges of SCN, there is a need to prioritize and address the constructs. The study thus combines two multiple criteria decision making (MCDM) tools, the analytical hierarchy process (AHP) and quality function deployment, to prioritize the constructs identified from literature and supported by field studies. The house of quality (HOQ) has been used for analyzing different stakeholders’ requirements. The degree of importance for HOQ-1 has been derived using the AHP tool. The study revealed the most intriguing issues and challenges of e-waste processing plants considering the requirements of different stakeholders. The results showed formal collection, storage, semi-informal collection, and e-waste quality to be the major issues of processing plants. The findings obtained from MCDM analysis have been validated though two case studies in India and China. If the results obtained are applied to the existing e-waste SCN, a holistic e-waste management system can be achieved for developing countries.

“…It is a very important fact for the COVID-waste that at their site of generation they are appearing as a relatively “source segregated” waste, due to the presence of contagious virus, which makes it un-mixable with other wastes. Segregated waste is always best for maximum resource recovery [ 25 ]. Many researchers confirm that pyrolysis of waste plastics yields significant quantity of oil (more than 50% wt.…”

“…This will drive the adoption of pyrolysis as an efficient COVID-waste management and recycling method and construction of dedicated pyrolysis plants for the said purpose. The generated pyro-oil are used as an alternative fuel in gas turbines, generators, and boiler systems [ 25 ]. The fuel value of obtained distilled pyro-oil of packaging waste (PP, LDPE, and HDPE) was close to diesel with long hydrocarbon chains (>C20) which confirms the robustness of the technology [ 41 ].…”

“…Pyrolysis will serve as an alternative and arguably a sustainable technology to handle the present COVID-waste stream in short term and long term. Compared to incineration, pyrolysis is reported to be an eco-friendlier and resource-efficient process [25]. As a well-known green engineering approach, pyrolysis has long been adopted for recycling multiple types of solid waste including both biomass and plastic wastes [26][27][28][29].…”

Since the end of 2019, COVID-19 pandemic has affected 220 countries and currently majority of the world is facing the wrath of the second wave. One of the outcomes of the ongoing pandemic is the generation of huge amount of solid polymeric “COVID-waste” comprising medical waste, personal protective equipment (PPE) waste, packaging waste, and other household waste with potential infectious components residing on it. Thermochemical route is the preferred treatment and effective way of disposal of such infectious polymeric waste. Typically, incineration is employed to ensure complete destruction of the pathogens which is not a resource-efficient method. Pyrolysis is a sustainable alternative which can handle the present COVID-waste stream in short-term and long-term yielding valuable fuel and material products. Recently published literature in this avenue have clearly shown the versatility of this technology in efficiently handling both mono and mixed stream of polymers. Based on facts, we propose a resource resurgence framework that utilizes pyrolysis as the core conversion route for effectively handling COVID-waste streams. Our framework suggests how these plants can be operational and helpful in generation of revenue in post-pandemic times as well. We expect that the conscientious adoption of pyrolysis will certainly lead us towards a circular economy paradigm.

“…Putrescible waste is the main fraction of MSW stream in developing countries (1)(2)(3)(4)(5). Putrescible waste disposal in a landfill leads to catastrophic environmental impacts such as global warming by greenhouse gases emission and groundwater contamination by toxic leachate generation (1,(6)(7)(8)(9)(10)(11).…”

Composting is a preferable treatment option for putrescible waste disposal. In the small-scale composting, the control of the process is easy and high quality compost is usually produced while the conditions of industrial composting and small-scale composting are so different especially in developing country that municipal solid waste (MSW) is collected as commingled. Unfortunately, there is still a lack of information and experiences regarding the successful industrial composting from commingled municipal solid waste (CMSW). Therefore, this study was conducted on the compost production from CMSW in Shiraz City, Iran, with the composting capacity of 100 tonnes per day. The common process of windrow composting was modified for industrial composting in Shiraz City. The efficiency of the modified process was assessed using physical, chemical, and economic analyses. In addition, the maturity and stability of produced compost was evaluated using different indices such as fertilizing index (FI), clean index (CI), static respiration index (SRI), cumulative respiration index (CRI), and C-CO2 production index (C-CO2 Index). Finally, solutions and suggestions were presented to improve the system performance. Results showed that although the input putrescible waste to composting site has low homogeneity, produced compost in Shiraz City has a “good” quality. The produced compost with FI and CI of about 4.2 and 3.6, respectively, has high fertilizing potential and medium heavy metal content and can be sold without any restriction. Based on the economic analysis, poor marketing, strategies of bad marketing, lack of public awareness, and visible impurities, in spite of complying with the required standards, are the main reasons for the low sale price. The results of this study can be valuable for industrial composting in the cities where wastes are not separated at source.
