The purpose of this paper is to investigate the proposition that there is a symbiosis effect for exchanges between household waste recycling systems (HWRSs) and household recycling behaviour (HRB) within the reverse logistics (RL) discourse.

The paper contains empirical findings from a two phase, multi-method approach comprising consecutive inductive and deductive investigations. The qualitative and quantitative data underpin exploratory and explanatory findings which broaden and deepen the understanding of this phenomenon.

Analysis identified significant interactions between situational and personal factors, specifically demographic factors, affecting HRB with key factors identified as engagement, convenience, availability and accessibility.

Findings confirm the existence of a symbiosis effect between situational and personal factors and inform current research trends in the environmental sciences, behavioural and logistics literature, particularly identifying consumers as being an important pivot point between forward and RL flows.

Findings should inform RL-HWRSs design by municipalities looking to more effectively manage MSW and enhance recycling and sustainability. RL practitioners should introduce systems to support recovery of MSW in sympathy with communication and education initiatives to affect HRB and should also appreciate a symbiosis effect in the design of HWRSs.

The social implications of improved recycling performances in municipalities are profound. Even incremental improvements in the performance of HWRSs can lead to enhanced sustainability through higher recycling rates, reduced diversion of MSW to landfill, decreases in pollution levels, reduced carbon footprints and reduction in depletion of scarce natural resources.

The paper marks an early contribution to the study of symbiosis in HWRSs and HRB pertaining to RL. Findings are offered that identify the key situational and personal factors that interact to affect enhanced HWRSs and also offer insights above those available in current multi-disciplinary literature that has largely examined such factors in isolation. Conclusions offer the possibility of an epistemological bridge between the social and natural sciences.

This study aims to extend the theory of planned behaviour (TPB) model to explain youth’s recycling behavioural intentions in India. Perceived moral obligation (PMO) to perform such pro-environmental activities is incorporated in the TPB model. The study also aims to validate the extended version of TPB models with direct and indirect relationships and identify the best competing model among original TPB, extended TPB model “Model A” (moral obligation is an explanatory variable to recycling behaviour) and extended TPB model “Model B” (moral obligation as an explanatory variable to attitude, perceived behavioural control [PBC] and recycling behavioural intentions; and responsive variable to subjective norms) to predict Indian youth’s waste recycling behaviour.

The descriptive study adopted a hypo-deductive research design to test the proposed extended TPB models. The study used a survey research design with a structured questionnaire. A sample of 782 youth with a mean age of 18 was obtained to perform the correlational analysis. The scale validity and reliability are measured using structural equation modelling and identified the robust model with higher explanatory power using the Chi-square difference (Δχ²) statistic test.

Results show that the extended TPB model “Model B” has a better fit and explanatory power than competing models to predict the waste recycling behaviour of youth. Further findings substantiate that PMO has a higher indirect effect on recycling intention. Model B supports the utility of moral obligation and its association with youth’s higher waste recycling intention and actual recycling behaviour.

The study considers solid waste recycling in general, and therefore future research should test the proposed model specific to other household wastes like water recycling. Furthermore, future studies can experiment with the model with additional variables like perceived relative benefits, social benefits, self-efficacy and education level of the respondents. In a strict sense, the research concern the respondents and the generalisation to a broader population should be made with caution. Hence, further studies in various geographical areas with larger sample sizes would allow the generalizability of the results.

This research provides insights into PMO and its influence on recycling intention. Promoting waste recycling behaviour through campaigns, social pressure and accepting the phenomena of “significant others” will encourage better waste recycling behavioural purposes. Indian households who are highly concerned and obliged towards environmental protection would develop favourable attitudes and subjective norms towards waste recycling.

The study proved the effect of subjective norms on intentions. This contention explains that recycling mostly happens within the house and is mostly not witnessed by society and friends. Therefore, adopting waste recycling behaviour is not socially acceptable as they are not fully aware of its benefits. Policymakers should create awareness to develop environmental-friendly behaviour through recycling solid waste and develop exclusive campaigns to sensitise the negative impact on the environment.

The study’s originality is to test the extended TPB model “Model B”, with PMOs as an additional key variable, which has higher explanatory power to predict the youth’s waste recycling behavioural intentions in the Indian context. PMO found a positive and significant effect on attitude, PBC and recycling behavioural intentions. The higher indirect result of PMO on behavioural purposes through TPB variables indicates the importance of personal moral obligation in pro-environmental behaviour.

This study aims to address the management of reverse flows in the context of service supply chains. The study builds on the characteristics of services production reported in literature to: identify diverse types of reverse flows in services supply chains, discuss key issues associated to the management of reverse service flows and suggest directions for research for developing the knowledge for management of reverse flows in service contexts.

This study first provides an overview of the theoretical background which supports the identification and the characterization of the flows, and the reverse flows, involved in service production. A short summary of each paper accepted in this special issue is also provided to give readers an overview of the various issues around reverse exchanges in service supply chains that authors have attempted to address.

In this study, the authors identify distinct types of reverse flows in services production building on the analysis of the characteristics of service production and delivery reported in the literature. Our discussion highlights the fact that service supply chains can be quite diverse in the type of exchanges of inputs and outputs that take place between customers and providers, showing that often there can be substantial flows of items to return. In particular, and differently from manufacturing contexts, the authors highlight that in service supply chains, providers might need to handle bi-directional reverse flows.

The lack of research on reverse service supply chains is, to a great extent, a consequence of dominant paradigms which often identify the absence of physical product flows as a key distinguishing feature of service supply chains, and therefore lead to the misbelief that in services there is nothing to return. This special issue therefore aims to clarify this misunderstanding through the limited selection of eight papers that address various issues around reverse exchanges in service supply chains.

While theoretical and empirical research in supply chain is abundant, management of reverse exchanges in service supply chain is sparse. In this special issue we aim to provide the first contribution to understand how the characteristics of service production raise new issues for the management of reverse flows in service supply chains, and to foster the development of adequate management strategies.

The purpose of this paper is to determine how best to reduce, reuse and dispose of household waste medicines in the National Health Service (NHS) (UK).

Through a combination of literature review and empirical work, this research investigates the existing household waste medicines reverse logistics (RL) system and makes recommendations for improvement by benchmarking it against household waste batteries RL. The viability and feasibility of these recommendations are evaluated through in-depth interviews with healthcare professionals and end user surveys.

The batteries RL system appears to be a more structured and effective system with more active engagement from actors/stakeholders in instigating RL practices and for this very reason is an excellent comparator for waste medicines RL practices. Appropriate best practices are recommended to be incorporated into the waste medicines RL system, including recapturing product value, revised processing approaches, system cooperation and enforcement, drivers and motivations and system design and facilitation.

This study offers academics and professionals an improved insight into the current household waste medicines RL system and provides a step towards reducing an existing gap in this under-researched area. A limitation is that only a small sample of healthcare professionals were involved in subjectively evaluating the feasibility of the recommendations, so the applicability of the recommendations needs to be tested in a wider context and the cost effectiveness of implementing the recommendations needs to be analysed.

Reducing, reusing and properly disposing of waste medicines contribute to economic sustainability, environmental protection and personal and community safety. The information retrieved from analysing returned medicines can be used to inform prescribing practice so as to reduce unnecessary medicine waste and meet the medicine optimisation agenda.

This paper advocates learning from best practices in batteries RL to improve the waste medicines RL design and execution and supports the current NHS agenda on medicine waste reduction (DoH, 2012). The recommendations made in the paper not only aim to reduce medicine waste but also to use medicines effectively, placing the emphasis on improving health outcomes.

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.

Research shows a recycling behavior gap where end consumers are positive towards recycling but do not act in accordance with their intentions. Such a gap creates challenges for reverse logistics systems. The purpose of this paper is to investigate how adaptations in reverse logistics systems towards end consumers-turned-suppliers can improve recycling behavior.

A framework with three propositions is developed and evaluated empirically using a two-group dependent post-test quasi-experimental design. The empirical setting is recycling of household waste. Three interventions are evaluated as: (1) the social norms nudge, (2) the distance nudge and (3) the availability nudge.

The results show that nudging improved recycling action behavior for the experimental group. Control group behavior remained constant.

This paper suggests that the end-consumer’s role as suppliers needs to be included more actively into reverse logistics systems for products to enter the preferred loops of recycling in the circular economy.

A new field of climate psychology is used to explain challenges in reverse logistics systems and nudging is demonstrated as a tool with which to deal with them. The study also shows how quasi-experiments can be applied in logistics research.

Food waste at the household level represents a major component of all food waste. Therefore minimizing food waste at the household level remains an important component of the food chain responsibility. This study explores the problem of food waste in Mauritius through an understanding of households' attitudes toward food waste and their motivations and barriers to food waste recycling.

The study uses a grounded theory approach to identify thematic categories that represent participants' attitudes toward food waste and the barriers they face to food waste reduction. We used a purposive sampling technique to guide the selection of participants. Interviews were conducted with 14 participants: three experts in food waste and 11 households. The data were analyzed using the tools of grounded theory.

Participants' expressed views on food waste included (1) guilt toward wasting food; (2) (lack of) environmental awareness; (3) financial considerations and (4) exemption from responsibility. The findings also led to the development of four themes that defined the barriers participants face to recycling food waste: (1) lack of awareness; (2) space limitations on recycling methods; (3) inadequate policy and (4) lack of time/priority.

Addressing the problem of food waste requires a holistic approach that takes into account households' attitudes to food waste, their motivation and barriers to food waste recycling as well as the regulatory and institutional framework governing food waste management in Mauritius. Policymakers should try to improve households' knowledge about food waste through educational campaigns. The authorities can provide different types of bins to households freely to facilitate the sorting out of waste and impose a fee for food waste generated beyond a certain limit or provide subsidies to them for handling food waste properly.

The management of food waste is particularly challenging for small islands developing states because of their unique characteristics of smallness, limited resources and environmental vulnerability. Appropriate interventions to reduce household food waste require place-based and geographically sensitive analyses that take into account the specificities of local food and waste management systems and cultural norms with respect to food. However, there is not only a paucity of research on household food waste, but most studies have been carried out in nonisland economies. The study contributes to the limited research on household food waste in small islands.

The purpose of this paper is to examine the factors that encourage households’ source separation behaviour in Accra and Tamale Metropolises in Ghana.

Using a cross-sectional design, 855 households of Ghana were interviewed based on the theoretical framework of the theory of planned behaviour (TPB). The ordered probit regression model was employed to examine the factors that influence households’ source separation intention.

The results indicated that educational attainment of head of household, total income of household, occupation type of household head, information, past experience with source separation, inconvenience in terms of time, space and availability of formal source separation scheme, attitude, subjective norm and the location of the respondents significantly predicted households’ solid waste separation intentions.

The cross-sectional design does not determine causality but an association. Thus, future studies should examine actual household waste separation behaviour by using the experimental design to test the TPB model.

To promote solid waste separation at source, the public should be educated and provided with solid waste separation schemes that are efficient and compatible with households’ preference.

This study was partly motivated by the fact that despite the benefits associated with source separation, little attention has been given to formal source separation in Ghana. Moreover, there are limited studies on source separation behaviour in Ghana using the TPB as the theoretical framework.

This study aims to investigate the domestic sustainable consumption practices in Indian households and the motivations to do so. These practices also contribute to environment management and its impact on Indian society through the action of reusing, reducing and recycling of consumed products for two generations, namely, the Baby Boomer and the Generation Z.

An exploratory qualitative research was undertaken in which the data were collected through personal interview technique with 64 respondents including males and females from the generations of Baby Boomers and Generation Z of Indian households.

The theoretical framework of the 3R was extended to inculcate broader themes like awareness, action and motivation for the domestic sustainable activities. The findings conclude that the domestic sustainable consumption practices of Baby Boomers in India were far more advanced than their Generation Z counterparts. These two generations differed in their awareness sources, actions of sustainability and the motivations for undergoing the domestic sustainable activities. Managerial implications have been framed for organisations like start-ups, sustainable firms, government organisations and second-hand product vendors. These practices in such organisations could help in the enhancement of circular economy through the domestic waste disposal.

Practical implications are for organisations that can consider the domestic sustainability consumption practices while planning their strategies to maximise stakeholder satisfaction through their corporate social responsibility initiatives and create more goodwill and growth avenues for their businesses.

Where most of the past literature concentrates on the supply chain and manufacturing initiatives of sustainability or sustainable consumption, very few studies look at the angle of domestic sustainability initiative and how they could be linked to the initiative of circular economy. This paper fills this gap in past literature.

Mauritius is a Small Island Development State (SIDS) with limited resources, and it has been witnessed that many containers used for storing household and industrial products are made from plastic. When discarded as waste, those plastic containers pose a serious environmental and economic challenge for Mauritius. Moreover, landfill space is getting increasingly scarce, and plastic waste is contaminating both land and water. Therefore, it is of the utmost necessity to develop solutions for Mauritius' plastic wastes. Due to its abundance and accessibility, plastic waste is a promising material for recycling and energy production. One potential solution is the use of machine learning and artificial intelligence (AI) to predict household plastic consumption, allowing policymakers to design effective strategies and initiatives to reduce plastic waste. Such information is a critical component to be able to efficiently plan for the collection and routing of trucks when collecting recyclable plastics. The development of new strategies for the recycling of plastic waste and development of new industry can address the import and export potential of the country to achieve self-sustainability as well as contribute to reduction in plastic pollution and amount of waste landfilled. These plastics can thereafter be used effectively for recycling and for the making of 3D printing filaments which fall under the SDGs 9 (Industry, Innovation and Infrastructure) and 12 (Responsible consumption and production).
