The purpose of this paper is to outline the socio‐economic and environmental implications of the informal sector engaged in waste recycling in the city of Kanpur, with special emphasis on the lives of lowest group of people, i.e. waste‐pickers, and to discuss various possible scenarios to integrate them with the formal sector.

The study involved field survey of secondary material markets, followed by the administration of questionnaires to 40 respondents belonging to various segments of the informal sector. The questionnaires were designed to elicit information on the socio‐economic characteristics of the respondents. The study was conducted in 2004.

The study has attempted to delve into the socio‐economic conditions of the waste and dump‐pickers, the lowest segment of the informal recycling sector. The study of the status of existing alliances of formal‐informal sector and the community shows that there is a lot of scope for improvement in the management of solid waste and the condition of the informal waste‐recycling sector. Stronger alliances have the potential to improve the services as well as the socio‐economic condition of the informal waste‐recycling sector.

A very small sample size was selected for this study in the absence of any prior database pertaining to the size, socio‐economic conditions of the informal waste‐recycling sector.

The paper attempts to understand the important role played by the informal sector engaged in waste recycling. This work is original, as no such analysis has been carried out in the study area. This study could be further extended.

An early morning at Bryant Salvage, a Vietnamese recycling business, finds a variety of San Francisco's scavengers converging to sell their findings. Vehicle after vehicle enters the yard to be weighed on the huge floor scale before dumping its load in the back; ancient pick‐up trucks with wooden walls, carefully loaded laundry carts, canary Cadillacs stuffed to overflow with computer paper, the shopping carts of homeless men, a 1950s ambulance carrying newspaper, and even the occasional gleaming new truck. The homeless men unload their towers of bottles and cardboard while young Latino van recyclers shout jokes across them. Middle aged Vietnamese women in jeans and padded jackets buzz around on forklifts or push around great tubs full of bottles and cans, stopping occasionally to help elderly people with their laundry carts. The van recyclers repeatedly honk their horns at the homeless guys to get out of the way. The homeless recyclers, silently methodical in their work, rarely respond.

Waste generated from electrical and electronic equipment, collectively known as E-waste, remains a persistent environmental, economic and social problem. Sustainable E-waste management (EWM) has numerous benefits, such as preventing electronic waste from entering landfills, reducing the need for virgin materials by recovering valuable materials from recycling and lowering greenhouse gas emissions. Circular economy (CE) practices are considered the initial steps toward sustainable EWM, but some hurdles have been reported in the adoption of these practices. Therefore, the current study aims to identify the common CE practices, sustainability of the EWM process and the challenges in EWM, and to develop a conceptual framework for effective EWM.

Very few studies have proposed frameworks that acknowledge the challenges and CE practices of EWM. To fill this gap, a systematic literature review (SLR) was performed, and 169 research articles were explored.

A total of seven challenges in the adoption of effective EWM were identified: rules and policy, infrastructure, consumer behaviour, informal sectors, community culture, technology and economy. Eight common CE practices were also found for effective EWM: reuse, recycle, remanufacturing, refurbishment, repair, reduce, recover and repurpose.

A conceptual framework guiding sustainable EWM was proposed, which includes solutions for the identified challenges, and CE practices with sustainable benefits.

With rapid industrialization and urbanization, municipal solid waste (MSW) management has become a serious challenge worldwide, especially in developing countries. The Beijing Municipality is a representative example of many local governments in China that are facing MSW management issues. Although there have been studies in the area of MSW management in the literature, less attention has been devoted to developing a structured framework that identifies and interprets the barriers to MSW management in megacities, especially in Beijing. Therefore, this study focuses on identifying a comprehensive list of barriers affecting the successful implementation of MSW management in Beijing.

Through an extensive review of related literature, 12 barriers are identified and classified into five categories: government, waste, knowledge dissemination, MSW management process and market. Using an integrated approach including the decision-making trial and evaluation laboratory (DEMATEL), maximum mean de-entropy algorithm (MMDE) and interpretive structural modeling (ISM), a conceptual structural model of MSW implementation barriers is constructed to provide insights for industrial decision-makers and policymakers.

The results show that a lack of economic support from the government, imperfect MSW-related laws and regulations, the low education of residents and the lack of publicity of waste recycling knowledge are the main barriers to MSW management in Beijing. Combined with expert opinions, the paper provides suggestions and guidance to municipal authorities and industry practitioners to guide the successful implementation of MSW management.

The findings of this study can provide a reference for MSW management in other metropolises in China and other developing countries.

This study proposes a hybrid DEMATEL-MMDE-ISM approach to resolve the subjectivity issues of the traditional ISM approach and it analyzes the barriers that hinder MSW management practices in Beijing.

Recycling and reuse of the electric vehicle (EV) batteries are ways to extend their limited lives. If batteries can be traced from production to recycling, it is beneficial for battery recycling and reuse. Using blockchain technology to build a smart EV battery reverse supply chain can solve the difficulties of lack of trust and data. The purpose of this study is to discuss the behavioural evolution of a smart EV battery reverse supply chain under government supervision.

This study adopts evolutionary game theory to examine the decision-making behaviours of the government, EV manufacturers with recycled used batteries and third-party EV battery recyclers lacking professional recycling qualification.

On the smart reverse supply chain integrated by blockchain technology, a cooperative recycling strategy of the third-party EV battery recycler is the optimal choice when the government tends to actively regulate. The probability of the EV manufacturer choosing the blockchain adoption strategy exceeds (below) the threshold, and the government prefers negative (positive) supervision. According to numerical analysis, in the mature stage in the EV battery recycling industry, when the investment cost of applying blockchain is high, EV manufacturers' willingness to apply blockchain slows down, the government accelerates adopting a negative supervision strategy and third-party EV battery recyclers prefer cooperative recycling.

The results of this study provide opinions on the strength of government supervision and the conditions under which EV manufacturers and third-party EV battery recyclers should apply blockchain and cooperate. On the other hand, this study provides theoretical analysis for promoting the application of blockchain technology in smart reverse supply chain.

Compared with previous research, this study reveals the relevance of government supervision, blockchain application and cooperation strategy in smart EV battery reverse supply chain. In the initial stage, even if the subsidy (subsidy reduction rate) and penalty are high and the penalty reduction rate is low, the EV manufacturer should rather give up the application of blockchain technology. In the middle stage in the EV battery recycling industry, the government can set a lower subsidy (subsidy reduction rate) combined with a penalty or a higher penalty (penalty reduction rate) combined with a subsidy to supervise it. The third-party EV battery recycler is advised to cooperate with the EV manufacturer when the subsidy is low or the penalty is high.

With the rapid increase in the consumption of electrical and electronic innovations, responsible management and recycling of electronic waste (e-waste) or waste electrical and electronic equipment (WEEE) has been a significant concern for the governments, stakeholders, researchers and industry practitioners around the world. Consumer awareness, disposal behaviour and perception are chief facets of designing sustainable management strategies. Although researchers have widely studied e-waste over many years, the research focusing on consumer awareness about e-waste recycling has gained momentum recently. This paper aims to systematise the existing literature and explore future research prospects on household e-waste sorting behaviour.

Web of science (WoS) core collection was searched using selected keywords to identify relevant articles published from 2001 to 2021. The search resulted in 1,156 research articles published from 2001 to 2021. After a detailed study, 85 articles were shortlisted for in-depth review. The review was conducted based on global trends, top journals, most prolific authors, most active e-waste research countries, and institutions centring on consumer participation in e-waste disposal and recycling behaviour. The present research has also identified around eleven factors that seem to have a bearing on consumer behaviour towards storage, disposal and recycling of e-waste.

E-waste research has gained increased attention in the last five years. The majority of the studies has focused on motivational factors and ignore the risks associated with handling e-waste. The present study reports the pertinent issue of lack of awareness among the masses about e-waste handling and disposal. Thus, bringing to the fore the lack of awareness programmes and initiatives. The analysis presents the gaps in the literature and future research agendas.

The review article will help in providing an in-depth understanding of consumer behaviour towards storage, disposal and recycling of e-waste and delineates the future direction of research that may be undertaken in this field of study.

Despite legislation in place, there is still a gap in knowledge and awareness of the communities on the issues of e-waste handling and management. It is important to understand the knowledge and awareness levels of the consumers of electronic products who ultimately become the generators of e-waste in a community. The current study is based on a survey conducted in an urban setting to understand people's perception about the genesis of issues related to e-waste and its management. The purpose of this paper is to study the findings that could help in designing customized awareness programmes for addressing this concern more effectively.

A survey was conducted in Delhi to understand public knowledge and awareness related to e-waste management in the city and country. A limited random survey was conducted with a sample size of 400 individuals in Delhi from middle class belonging to different educational backgrounds and professions. Personal interview method was used to collect in-depth information related to the issues of e-waste and its management. A questionnaire was developed and pilot tested before actual start of the survey. The questionnaire consisted of two sections – first about baseline information related to their age, family size, family income and educational background and second on their knowledge and awareness regarding e-waste and its management. Also, the practices they followed regarding e-waste at their household level were enquired. The questionnaire consisted of both open-ended and close-ended questions. Most of the questions had multiple-choice options, which made it easy for the respondents to answer them appropriately. The open-ended question gave the respondents ample time and space to express their views. The open-ended questions besides strengthening the close-ended questions provided a lot of qualitative information and made the study interesting. Apart from just interviewing, informal interactions were also used as a tool for data collection. During the course of the study, informal interactions were done with respondents to familiarize them with the objectives of the present study, their role and benefits to them from the study.

The present study aimed to gauge the awareness levels and practices of people regarding e-waste management. The survey conducted in Delhi revealed that significant fraction of middle-class population is still unaware of the issue; however, on getting the information they were able to link the impacts of improper management of e-waste with detrimental health outcomes. For those who knew about it, the main sources of information to them were found to be internet, and print media. However, despite some awareness about the issue, most respondents were totally unaware about correct ways of its recycling and management. An important finding of the study was that 12-26 per cent people replace their major electronic goods like refrigerators, food processors, personal computers and music systems within the first three years of purchase. Discarding products within their periods of useful lives leads to enhanced generation of e-wastes. Along with e-waste generation, this also puts additional stress over the resources used for manufacturing of these products. On management of e-waste, most of the respondents opined of need of having efficient recycling units and effective mass awareness programmes. The survey also revealed the willingness of users to pay extra cost for proper management of e-waste provided that there is proper cost sharing between consumers and producers. This also raises an important aspect of extended producer responsibility (EPR). EPR puts additional responsibility and onus on the manufacturer of the product to not only produce durable quality of products but also take back the obsolete products and manage the e-waste. This also means that the manufacturers will have to use recyclable material in manufacturing of new products for economic management of e-waste at the later stage. Although, in Indian context it would be a challenge to implement the concept of EPR, especially with the active informal sector. The respondents quite adequately put equal responsibilities on the government, consumers and producers for effective e-waste management. The study clearly highlights the issues perceived by the middle-class population of Delhi and can be replicated in other major cities for re-authentication of the facts. The study could prove to be important in designing awareness programme related to the issue.

This paper presents the results of a questionnaire survey-based study that was employed to understand the perception of a sample of respondents. Analysis of the data reveals that the knowledge on the issue of e-waste is minimal and requires massive awareness drives for senitization.

Increased demand for new batteries and strict government protocols have stressed the battery industries to collect and recycle used batteries for economic and environmental benefits. This scenario has forced the battery industries to collect used batteries and establish the formal battery recycling plant (BRP) for effective recycling. The starting of BRP includes several strategic decisions, one of the most critical decisions encountered is to find the best sustainable location for BRP. Hence, this paper aims to address the complexity of the issues faced during the BRP location selection through a hybrid framework.

In this study, the criteria are identified under socio-cultural, technical, environmental, economic and policy and legal (STEEP) dimensions through literature review and experts' opinions. Then, the hybrid methodology integrating fuzzy decision making trial and evaluation laboratory (DEMATEL), best worst method (BWM) and technique for order preference by similarity to an ideal solution (TOPSIS) has been proposed to find the inter-relationship between criteria, the weights of criteria and the best alternative.

The identified five main criteria and 26 sub-criteria have been analyzed through fuzzy DEMATEL, and found that the policy and legal criteria have more inter-relationship with other criteria. Then from BWM results, it is found that the support from government bodies has attained the maximum weightage. Finally, the second alternative has been identified as a more suitable location for establishing BRP using TOPSIS. Further, it is found from the results that the support from government bodies, the impact of emissions, availability of basic facilities and community health are the essential criteria under STEEP dimensions for establishing BRP.

In addition to the various existing sustainable criteria, this study has also considered a set of policy and legal criteria for the evaluation of locations for BRP. Further, the hybrid MCDM method has been proposed in this study for selecting the best alternative. Thus, this study has yielded more insights to the decision-makers in choosing a sustainable location for BRP.

This article aims to draw insight from a variety of management disciplines to encourage a broader view of the economy as it relates to sustainable waste management (SWM) development.

The paper presents a framework to describe how strengths can be blended to support environmental sustainability (ES), highlighting the need for community cooperation between the informal and formal sectors of the economy.

Unique contributions for SWM can emerge from both economic sectors and, when leveraged, may drive community development within local municipalities.

The platform addresses the need for more flexible governmental policies that encourage waste management activities among formal and informal workers.

The paper brings forward typically disregarded ES waste management opportunities that reside within the informal sector, an often overlooked aspect of the broader economy.

This study aims to test whether faculty and students who have developed the most pro-environmental values and concerns are also the most likely to reduce the on-campus waste stream. It does so by using the theory of ecological modernization.

Questionnaires were created and disseminated to a representative sample of 590 undergraduate students and faculty on one college campus. This research took place after widespread efforts were made to increase faculty and student knowledge of the college’s recycling guidelines.

Among the measures of environmental orientation (values, concern about pollution and green consumption), only environmental values were associated with claiming to know guidelines and self-reporting higher levels of recycling effort. None was associated with knowledge about local recycling guidelines.

Research on recycling programs at other campuses would help move beyond this specific case. The use of longitudinal surveys would help establish time-order.

This research makes an important contribution by measuring the impact well-intentioned people have on the waste stream. Without thorough knowledge of local recycling guidelines, even the most environmentally oriented people with the best of intentions may contribute to the waste stream by throwing away things that can be recycled and contaminating recycling bins with non-recyclable materials. The authors conclude that activist interventions are necessary to teach about campus recycling guidelines to reduce the waste produced on campus.
