Recycling has experienced rapid growth as a technique to reduce the solid waste stream volume. Despite the public appeal and acceptance of recycling, the reverse logistics channels used in recycling have received minimal attention. However, the reverse channels′ membership and capabilities have a significant impact on the efficiency of processing recyclable material for remanufacture into recycled products. Differing product characteristics, extensive handling, and low density shipments pose considerable obstacles to establishing an efficient reverse channel for recyclable commodities. A framework, based on interviews and current literature, describes the reverse logistics channel structure, membership and functions, and provides a foundation for identifying the issues affecting efficiency and marketability, and possible future directions for improving efficiency within the reverse channel structure.

Municipal solid waste (MSW) consists mainly of several recyclable materials such as paper and cardboard. Inside the educational institutes, especially universities, MSW is generated from several facilities including offices and cafeterias. Without an effective management program, solid waste can have detrimental impacts on the environment. This paper aims to assess the solid waste management practices followed at the main campus of Imam Abdulrahman Bin Faisal University (IAU), Dammam – Saudi Arabia.

The MSW samples were collected from different sources inside the IAU campus such as the college buildings (such as the teaching rooms and staff offices), the administrative buildings and services buildings (e.g. the main library, the photocopying center, the restaurant and cafeteria) at least one time per week during a full academic term (January–May) of the academic year 2017–2018. The collected MSW samples were segregated into seven categories, and the net amount of each category and the overall weight of the MSW were determined once every week. The MSW samples were characterized for physical and chemical properties including moisture, carbon and ash contents. Food product waste (FPW) of the main university restaurant was studied separately.

Data on the composition of MSW samples revealed that 80% of wastes were recyclable, 19% as compostable materials, while only 1% of the materials were a non-recyclable waste. More than 73% of the recyclable materials include paper and plastic warranting dire need of an effective solid waste management program. The highest value of FPW was recorded for the breakfast meal.

Most of the waste generated from the university campus was recyclable type that needs to be handled carefully to avoid its mixing with other types of the waste stream. Waste characterization is an important tool that helps in understanding the amount and pattern of waste generation. It can be used as a decision-making tool for implementing sustainable waste management programs for universities.

This paper aims to address convenience as a prominent feature of a scheduled society and examines the nature of convenience, identifies the waste collection system and recycling programmes in some densely populated areas in Asia and discusses the existing barriers to enhancing the convenience of the recycling facilities in Hong Kong. The paper further identifies some recommendations for the policy and design of recycling practices and facilities.

In this qualitative study, two districts in Hong Kong from 2013 to 2014 were used as case studies. The research methods included field observations, semi-structured interviews and ethnographic research. The locations for field observation included lobbies, corridors, lifts, ground floors and streets. Direct interviews were conducted with residents, cleaners, government officials and expert planners and environmentalists. In-depth interviews and observations were conducted with six families following the interviews to identify important issues that might have been ignored in the semi-structured interviews and field observations.

A holistic understanding of convenience in a scheduled society is effective in the design of high-quality recycling facilities. In terms of convenience, the gap between recycling and not recycling is rather obvious in Hong Kong. Therefore, it is necessary and important to adjust the difference in the degree of convenience regarding refuse disposal and recyclable collection. In addition, the enhancement of economic incentives could shift the degree of convenience and encourage public participation in recycling. The challenges of specific living conditions and social contexts should also be taken into account to enhance the convenience of recycling.

Further case studies are expected in other countries and cities with the purpose of gaining an in-depth understanding of the means by which to approach the convenience of recycling programmes within various social contexts. Comprehensive and continuous studies on these factors are recommended throughout the design and implementation processes to account for constantly changing situations. A clear understanding of convenience from the perspective of the users is important.

The findings provide reference and direction for a holistic approach to the design and management of recycling facilities in Hong Kong. The findings also advocate the consideration of convenience from the perspective of the users.

The findings illustrate how to design and manage public facilities for waste recycling in ways that encourage household and community participation in terms of convenience.

The paper identifies the manner by which the culture of convenience and an institutionalised rhythm influence recycling practices. Although substantial studies on recycling indicate that convenience is a necessary characteristic of designs and services, the nature of convenience and the means by which to approach convenience in terms of public facilities are seldom discussed. The paper proposes several recommendations on the basis of the studies of the refuse collection programmes in other areas of Asia and case studies in Hong Kong. The findings provide insights for policymakers, researchers and designers to improve the design of public facilities.

This paper aims to describe the effects of 3R (reduce, reuse and recycle) waste management initiatives on a campus community. It ascertains the environmental attitudes and opinions of the residents and investigates their behavioral responses to waste management initiatives. Practical implications for enhancing sustainable waste management are discussed in this paper.

Demonstration projects on waste segregation and recycling, as well as waste a reduction campaign, were set up on the campus to ascertain people’s attitudes and investigate their behavioral responses toward 3R practices. Data were collected through a questionnaire survey, observations, interviews and the project’s document review. A waste audit and waste composition analysis was carried out to assess waste flows and actual waste management behaviors and measure the change in the recycling rate.

3R waste management initiatives had positive effects on people’s attitudes about resources, waste management and consciousness of the need to avoid waste, but these initiatives did not affect recycling and waste management behavior. A voluntary approach-only cannot bring about behavioral change. Incentive measures showed a greater positive effect on waste reduction to landfills. Nevertheless, the demonstration projects helped to increase the overall campus recycling from 10 to 12 per cent.

This paper addresses a literature gap about the 3R attitudes and resulting behavior as part of campus sustainability of higher education institutions in a developing country. The authors’ results revealed hurdles to be overcome and presents results that can be compared to behavioral responses of people from other developed countries. These findings can be used as a guide for higher education institution’s policy-makers, as they indicate that voluntary instruments alone will not yield effective results, and other mechanisms that have an impact on people's behavior are required.

Sustainable recycling activities in higher education institutions (HEIs) are crucial as it serves as a common benchmark to a community that is socially and environmentally responsible. This chapter presents a suitable case study of HEIs in Malaysia reporting on recycling rate, monitoring the recycling patterns, and matching the significant recycling policy in the HEIs. Therefore, four HEIs including Universiti Teknologi Malaysia (UTM), Universiti Malaya (UM), Universiti Kebangsaan Malaysia (UKM) and Universiti Putra Malaysia (UPM) were selected as the suitable case studies to examine the practices of recycling activities. These four HEIs are Malaysian research universities that are ranked in the top 300 in the UI Green Metric World University Rankings. Several findings and previous works were reviewed; further steps to set a recycling target were identified and served as a guidance of the standard recycling rate. Results showed the selected HEIs reflected the low percentage of recycling rate in the range of 0.03–29.26%, depending on its practices and policy. Three phases of planning have been structured to target the recycling rate at HEIs in Malaysia with the First Plan (2025), Second Plan (2035) and Third Plan (2040) towards the recycling rates of 20%, 30% and 40%, respectively. The recommendations for the HEIs formulate recycling policies and recycling rates, and for waste management, academia and research centres to play a more active role in increasing the efficiency of recycling activities for a positive impact on the recycling rate in HEIs.

In this research, the authors apply artificial neural networks (ANNs) to uncover non-linear relationships among factors that influence the productivity of ragpickers in the Indian context.

A broad long-term action research program provides a means to shape the research question and posit relevant factors, whereas ANNs capture the true underlying non-linear relationships. ANN models the relationships between four independent variables and three forms of waste value chains without assuming any distributional forms. The authors apply bootstrapping in conjunction with ANNs.

The authors identify four elements that influence ragpickers’ productivity: receptiveness to non-governmental organizations, literacy, the deployment of proper equipment/technology and group size.

This study provides a unique way to analyze bottom of the pyramid (BoP) operations via ANNs.

This study provides a road map to help ragpickers in India raise incomes while simultaneously improving recycling rates.

This research is grounded in the stakeholder resource-based view and the network–individual–resource model. It generalizes these theories to the informal waste value chain at BoP communities.

This study aims to explore the state of environmental management accounting practice and the motivations for its use with a view to improving waste and recycling management by local government. The focus is on practice in local governments situated in the state of New South Wales (NSW), Australia. Prior studies suggest the need for environmental management accounting as a supporting tool for waste management.

An exploratory case study method was applied in 12 NSW local government organisations. In each local government interviews were conducted with managers responsible for waste and recycling issues.

Contrary to prior research this study found that, in the local governments investigated, an increasing amount of environmental management accounting information is being made available. The case studies found two main motivations encouraging the development of environmental management accounting in local government: first, social structural influences, such as regulatory pressures from different environmental regulatory bodies, environmental expectations from local communities, and pressures from peer councils; second, organisational contextual influences reflecting situational needs in the organisational contexts, such as complex waste operations and service designs, changes and uncertainties in waste and recycling management, and the council's strategic position for waste management.

The results imply that institutional theory and contingency theory provide different but complementary explanations for the development of environmental management accounting in waste management. Although previous environmental studies are overwhelmingly in favour of social system‐based theories, such as institutional theory, to explain environmental changes in organisations, an organisation's contextual dynamics seem to be equally important.

The findings about motivations provide useful information for environmental strategists and government regulators to make policies that improve accountability and the efficiency of waste and recycling management as well as promote future development of environmental management accounting to support sustainable waste management solutions.

Universities are an example of institutions that aggregate people around work/study who consume water, energy and produce waste daily in their activities, generating an impact on the environment. The purpose of this study is to determine the quantity, composition and recycling potential of waste generated at the Faculdade UnB Planaltina (FUP) campus, of the University of Brasilia in the Federal District, Brazil, to develop a waste management strategy compatible with national legislation and sustainable global practices.

This study was based on conducting on-site visits to identify the sources of generation, hazardousness, management and gravimetric characteristics of residual waste from 2015 to 2016. In 2016, a selective collection was implemented on the FUP campus, and since then, actions to raise awareness for the selective disposal and monitoring of waste were conducted with the academic community.

The results showed that the campus generates 148 kg of waste/day, whereas the per capita generation is 92 g/day. The production of hazardous waste is related to campus laboratories which manage it under a specific program. The campus restaurant is the place that generates the most waste, of which organic waste is the most representative. When categorizing the waste generated on campus, the authors found that the majority are recyclables at 67% of the total. This category includes material composed of cardboard, paper and plastic, all able to be recycled in the Federal District.

The recyclable waste generated at the FUP campus is being diverted from the city’s landfill because they are donated to a recycling cooperative. These actions promote income generation, social inclusion of waste pickers and a circular economy, all in compliance with the National Solid Waste Policy. As a result, the FUP campus is more in line with Brazilian legislation and the global context of adopting sustainable waste management amongst higher education institutions.

This paper contributes to the literature on sustainability in higher education by reporting the process of implementation of a waste management strategy in a university campus. Further, it presents tools and methods that can be used to achieve sustainability in waste management. The study also identifies that the crucial factor for the success of such actions is the mobilization and participation of the academic community in the process. It does so by presenting findings demonstrating how the University of Brasilia has been concerned with adopting pro-environmental measures for sustainable development.

The purpose of this paper is to assess the waste characteristics and separation efficiency of source separation of household waste in low- and middle-income communities in Kumasi Metropolis, Ghana.

A sample of 60 households participated in the household survey, education on source separation and pilot source separation exercise. The solid waste was sorted into six fractions and three recycling categories (biodegradable; paper and plastic; residue).

The mean generation rate of solid waste was 0.52±0.26 kg/per capita/day for the low-income community and 0.65±0.27 kg/per capita/day for the middle-income community. The waste fractions in the communities (low, middle income) were biodegradable organics (59.15, 65.68 per cent), plastics (11.01, 10.68 per cent), papers (3.15, 4.51 per cent), glass (0.89, 2.57 per cent), metals (0.96, 4.63 per cent) and miscellaneous (24.84, 11.93 per cent), respectively. The separation efficiency for organic category was 70 per cent, inorganic and residue was over 69 per cent and the paper and plastics was over 60 per cent.

The study suggests that the success of source separation programme hinges on education and economic incentives. It was noted that the sample size could be increased to enhance the accuracy of the data for prediction purpose.

The findings showed there is potential for recycling through source separation programme in low-and middle-income communities. Public education and economic incentives are necessary for successful source separation programme.

The paper provides insight into source separation to contribute to better understanding of how city authorities in developing countries could take advantage of economic incentives to scale-up recycling.

This study aims to test how waste disposal behaviors can be changed such as higher recycling diversion and lower contamination rates using signage and messaging techniques at public outdoor waste receptacles on a university campus.

The experiment took place at five public outdoor receptacle stations, each with a landfill and recycling receptacle, which were located in highly trafficked areas on the University of Florida campus. The study consisted of three phases, each lasting for three weeks. During phase one, no signage and messaging were introduced; during phase two, negative and concrete messaging was placed on signs that stood above the two receptacles; and during phase three, positive and abstract messaging was placed above the receptacles. Waste audits were conducted by separating and weighing the waste.

With signage and messaging implementation, the recycling diversion rates increased and contamination in the recycling receptacles decreased. However, there was not a consistent decrease in contamination in the landfill receptacles. The study also showed that the negative and concrete messaging was more effective at both increasing diversion rates and decreasing contamination rates at the recycling receptacles.

Waste managers on university campuses need to address the purpose and type of messaging being used at waste receptacles to maximize behavior and/or education outcomes.

To the best of the authors’ knowledge, this study represents the first time waste disposal behaviors have been analyzed and experimented on at public outdoor receptacles on a university campus.
