Opening the black box of food waste reduction

Surplus food management plays a key role in food waste reduction. This paper addresses the multifaceted concept of food supply chain sustainability by presenting a model of surplus food generation and management (called ASRW, Availability-Surplus-Recoverability-Waste), which encompasses the integrated food supply chain (i.e. business, environmental and social players). The model was developed using a bottom-up approach, by conducting 30 exploratory case studies and iterating theory development and data analysis. Three confirmatory case studies, from different food supply chain stages, are also presented to demonstrate how the model can be used to identify food waste reduction strategies.     

Ameliorating food loss and waste in the supply chain through multi-stakeholder collaboration

We elaborate mechanisms through which multi-stakeholder collaboration can ameliorate food loss and waste (FLW) from the end-to-end supply chain. In this context, we integrate the discourse on collaborative relationships in supply chains with stakeholder theory (roles and orientations) and use a multi-method approach combining systematic literature review (SLR) and embedded case studies based on secondary data. We develop a conceptual framework that illustrates collective stakeholder orientation emerging from aligned vertical and horizontal stakeholder orientation across the supply chain towards reducing FLW. We explain how achieving such alignment requires these stakeholders to navigate various collaboration conditions (structural and sporadic) that otherwise spur individualism, culminating in FLW mitigation efforts across food supply chains. We develop propositions, motivate future research, and offer practical implications.     

A system-wide interdisciplinary conceptual framework for food loss and waste mitigation strategies in the supply chain

The issues of food loss and waste (FLW) in the global supply chains have recently gained attention. However, causes for FLW and their mitigation strategies for curbing FLW at different stages of the supply chains remains under researched. Our research aims to address these research gaps in a three-fold way: i), we identified key causes (through root-cause analysis) of FLW in the supply chain of developed and less developed countries; ii), systematically classified measures and policies, which have been implemented to mitigate FLW; iii), developed an interdisciplinary conceptual framework for waste utilisation practices that can contribute towards the triple bottom-line in food system. A root-cause analysis was performed, and mitigation strategies identified by systematically analysing and synthesizing the extant research published over the past 20 years (1998 to 2018) in the areas of food loss and waste in the supply chain. A conceptual model for the prevention of FLW utilising a systems approach through the circular economy concept has been proposed. Since the agri-food sector is largely interdisciplinary, we have also demonstrated a method of integrating contributions from multiple disciplines in our proposed model towards achieving a total depollution (zero waste supply chain).     

A mixed-methods study of retail food waste in New Zealand

Little is known about the amount of food wasted in the retail sector. This study aimed to quantify retail food waste in New Zealand (NZ) and identify key drivers for food waste reduction, using a mixed-methods, observational study design that consisted of three parts: onsite food waste audits undertaken in 16 selected stores (complete data from 11 stores); semi-structured interviews with key retail staff from each store; and obtaining existing data from retailers. Retail food waste in NZ was estimated at 13 kg/capita/year for all food waste and diverted product (i.e. all food not sold or utilised at a retail level), which included 5 kg/capita/year designated as food waste (i.e. food directed to landfill, protein reprocessing and compost), with 3 kg/capita/year of this sent to landfill. Fresh vegetables (27%), bakery (23%), meat and fish (19%) and fresh fruit (17%) contributed the most to discarded product. The motivators for encouraging food waste reduction were: concern for the environment; making profit; caring for the community; and doing the ‘right’ thing. The barriers to food waste reduction were: training and educating staff; food safety concerns; quality standards; availability and capacity of waste diversion avenues; and lack of available resources. Audit data and food waste data recorded by retailers were similar. NZ has a number of policies and practices that successfully divert retail food waste away from landfill, in particular, retailers have established relationships with various groups that use their waste as a resource including protein reprocessors, local farmers, and food rescue charities.     

Measurement,mitigation and prevention of food waste in supply chains: An online shopping perspective

This study introduces a framework and model, although applied in a practical setting, sets the stage for further theoretical development of mid-range theory. The methodology applied in the study has four main stages, namely interviews with managers from an online food retail supply chain, analysis of soft and hard data using questionnaire-based surveys of customers and suppliers, archival and factual information gathered from the supplier and the online food retailer to measure food waste across the supply chain and analytical models to quantify various effects. A number of propositions emerged from our multiple methodologies and observations. The major research contribution of this work is to advance Natural Resource Based View (NRBV) to the supply chain and various complexities involved in food waste management. Dynamic capabilities were clearly evident and necessary in rapidly changing industrial contexts such as online food supply chains. This paper also proposes a food waste minimization-and-mitigation model, establishes the direct and indirect outputs of food waste and brings attention of the food waste debate in the context of an exemplar online food supply chain, as well as provides a middle range theoretic framework to enhance understanding on theory and its application to this field informed mainly NRBV.     

Cognitive barriers to collaborative innovation generation in supply chain relationships

This research investigates the cognitive barriers to the generation of collaborative innovations among supply chain members. The results of our case study show how different perceptions of relationships between supply chain members can hinder the generation of collaborative innovations despite a shared managerial cognitive basis regarding the potential benefits of collaboration, Thus, we argue that the generation of collaborative innovations is largely dependent on the nature of multiple (not dyadic) supply chain relationships and managers' perceptions about the potential of these relationships. Our results provide important implications to supply chain relationships and their role in the generation of collaborative innovations.     

The paradoxes of food waste reduction in the horticultural supply chain

Research on on food waste is often reductionist, in that it attempts to measure food waste at single points within the supply chain. While this enables consideration of where food is being wasted within the supply chain, it does not necessarily answer why and how food is wasted across an entire supply chain. Using a paradox theory approach, the aim of this paper is to address these knowledge gaps by exploring the inherent paradoxes in resolving food waste across a supply chain. Drawing on in-depth qualitative research within the Australian horticulture industry, the findings reveal four macro-level paradoxes relating to policy, markets, responsibility, and marketing. This paper makes a novel contribution through consideration of a holistic, whole of chain perspective in relation to food waste. It also extends paradox theory into food waste scholarship. From a managerial perspective, the visibility of paradoxes highlights the need for organisations in the food supply chain to look beyond their own organisational boundaries and adopt a whole-of-chain approach in an attempt to address food waste.     

The role of Guanxi in green supply chain management in Asia's emerging economies: A conceptual framework

In recent decades, rapid industrial modernization and economic growth have brought substantial environmental problems such as air pollution, hazardous waste, and water pollution for the Asian emerging economies (AEE), in particular China, Taiwan, India, Malaysia, Indonesia, Thailand, and South Korea. These countries have started to adopt green supply chain management (GSCM) as a strategy to reduce the environmental impact. There are anecdotal evidences that the adoption of GSCM in this region is partly influenced by Guanxi – a cultural norm, which plays a significant role in relationship governance within supply chain activities among the AEE. Based on a systematic literature review, we develop a conceptual framework that characterizes the drivers and barriers for the adoption of GSCM practices, incorporating Guanxi as a moderator in the manufacturing sector of the AEE. The conceptual framework addresses the roles of two types of Guanxi in the adoption of GSCM: the relational Guanxi at individual level based on social exchange theory and the aggregated Guanxi at firm level derived from social capital theory. This recognition of Guanxi at two separate decision levels help companies better manage their relationships while they green their supply chains. Directions for future research and managerial implications are discussed accordingly.     

Reducing food waste through digital platforms: A quantification of cross-side network effects

To fight food waste, retail stores have begun selling perishable food close to the expiration date at discounted prices. To render this form of last-minute discounting effective, digital platforms have been developed with the major aim to connect local retail stores and their consumers by sharing information about these discounts. To sustain digital platforms, platform leaders need to ensure both consumers and retail stores remain active on it. To provide platform leaders with advice on how to create a sustainable digital platform, we examine how retail store activity on the digital platform affects consumer activity, and vice versa (also known as cross-side network effects). By combining a PVAR model and an impulse response function, along with data from a digital platform aimed at food waste reduction, we find that the effect of consumer activity on retail store activity is stronger and more long-lasting than the effect of retail store activity on consumer activity. We discuss the implications of our findings for both retail stores and digital platform leaders.     

The determinants of university–industry collaboration in food science in Italy

Firms’ collaboration with academic institutions expands their range of expertise and can support the development of business innovations in several industries. For technological as well as structural reasons, university–industry collaborations are especially important in the case of the food industry. This paper aims at assessing the drivers of knowledge transfer from academic departments to industry. We analyse the dynamics of private funding of university research activities and investigate the drivers of university knowledge transfer from food science university departments, identifying how they differ from drivers in other areas of science. The empirical investigation is based on the econometric analysis of financial data on the whole population of university departments in Italy. We provide some implications for policy, highlighting whether and how university food science departments differ from university departments engaged in other areas of science, and how their interactions with industry can be increased.     

The US fashion industry: A supply chain review

The fashion industry has short product life cycles, tremendous product variety, volatile and unpredictable demand, and long and inflexible supply processes. These characteristics, a complex supply chain and wide availability of data make the industry a suitable avenue for efficient supply chain management practices. The industry has also been in a transition over the last 20 years: significant consolidation in retail, majority of apparel manufacturing operations moving overseas and, more recently, increasing use of electronic commerce in retail and wholesale trade. This paper aims to review the current state of operations and recent trends across the fashion supply chain in the US. We use industry-wide data, articles from business journals, industry reviews and extensive interviews with an apparel manufacturer in California, and a major US department store chain to describe the current operational practices and how the industry is restructuring itself during the transition, focusing at the apparel manufacture and retail segments of the supply chain.     

Food waste,catering practices and public procurement: A case study of hospital food systems in Wales

This article aims to address the need for more comprehensive studies on sustainable food systems through a case study of hospital food waste in Wales, UK. Based on a mixed-method research approach that focused on the links between hospital food waste, catering practices and public procurement strategies, the article shows that the hospital meal system, in the case studied, is responsible for overall levels of food waste that greatly exceed the official percentages provided by the Health Board. In addition to showing the theoretical benefits of research that accounts for the complex interrelations between different stages of the food chain, the study raises the need for a more integrated political approach that mobilizes all actors in the food system around a shared vision for sustainable development.     

Can food waste behavior be managed within the B2B workplace and beyond? The roles of quality of green communication and dual mediation paths

Food waste is becoming increasingly a crucial issue to organizations, but little is known about workplace food waste reduction among frontline employees in the business-to-business (B2B) context regardless of the salience of frontline employees with such a behavior as green intermediaries in B2B supply chains. Our research seeks to fill this gap by investigating how and when quality of green communication in the B2B workplace influences frontline employees' workplace and household food waste behavior, as well as the relationship between these two types of food waste behavior among frontline employees. The dataset for this study came from sales employees in manufacturing companies based in Vietnam. The results unveiled the roles of employees' green role identity and harmonious environmental passion as the dual mediation paths for the relationship between quality of green communication and employees' intention to reduce food waste, which in turn attenuated both their workplace and household food waste behavior. The positive relationship was noted between employees' workplace food waste behavior and their household food waste behavior. The results further demonstrated the boundary condition role of household leftovers reuse routines to enhance the link between intention to reduce food waste and food waste behavior. The implications are discussed on initiatives for reducing B2B frontline employees' food waste behavior, thereby transforming them into green agents in B2B supply chains.     

An empirical analysis of supply chain risk management in the German automotive industry

The purpose of this paper is the empirical analysis of supply chain risk management practices. The analysis is based on a survey with 67 manufacturing plants conducted in the German automotive industry. After investigating the vulnerability of supply chains in general and examining key drivers of supply chain risks, the paper identifies supply chain risks by analyzing their likelihood to occur and their potential impact on the supply chain. The results are visualized in the probability-impact-matrix distinguishing between internal and external supply chain risks. Furthermore, instruments for dealing with supply chain risks are investigated. Therefore, the impact of supply chain risk management on performance is tested. In order to distinguish between companies with a high degree of supply chain risk management and those with no or only limited implementation the plants are grouped by means of a cluster analysis based on factors reflecting the instruments of supply chain risk management. In particular, groups are created representing two different approaches to deal with supply chain risks, i.e. reactive and preventive supply chain risk management. The clusters are investigated concerning differences in terms of performance criteria. The analyses reveal that companies with a high implementation degree show a better supply chain performance. Furthermore, the results show that the group using reactive supply chain risk management has higher average value in terms of disruptions resilience or the reduction of the bullwhip effect, whereas the group pursuing preventive supply chain risk management has better values concerning flexibility or safety stocks.     

An analysis of multi-stakeholder initiatives to reduce food loss and waste in an emerging country – Brazil

This paper aims to investigate the roles adopted by the distinct stakeholders that are engaged in a voluntary initiative to reduce food loss and waste (FLW) in the context of an emerging country. Data were collected by way of participant observation in multi-stakeholder events, observation visits and interviews with 54 food sector stakeholders, and from secondary data. The theoretical contribution of this paper is that it provides a systemic and realistic perspective for tackling FLW, as research in the field usually only focuses on one supply chain agent, or on consumer behaviour. Another contribution that may be replicated in other countries has to do with the role of each stakeholder in identifying the processes with which they are involved for reducing FLW. Activities and actions in a multi-stakeholder initiative change according to their positioning at the institutional or value chain level of analysis. Future studies should consider the extensive interplay that exists between the institutional and value chain levels in the food sector, and how they interact     

The effects of GSCM drivers and institutional pressures on GSCM practices in Taiwan’s textile and apparel industry

This empirical study of Taiwan’s textile and apparel manufacturers investigates the relationships between green supply chain management (GSCM) drivers (organizational support, social capital and government involvement) and GSCM practices (green purchasing, cooperation with customers, eco-design and investment recovery). It also studies moderating effects by institutional market, regulatory and competitive pressures. Through hierarchical moderated regression analysis, the results of this research show that (1) except for investment recovery, the other three GSCM practices are positively affected by GSCM drivers; (2) investment recovery is positively affected only by organizational support; (3) market pressure has no moderating effects on most of the relationships between GSCM drivers and GSCM practices; (4) regulatory pressure has positive moderating effects on most of the relationships between GSCM drivers and GSCM practices; and (5) competitive pressure has negative moderating effects on most of the relationships between GSCM drivers and GSCM practices. Finally, the implications of this study and future research are discussed.     

Individual antecedents to consumer intention to switch to food waste bioplastic products: A configuration analysis

Food waste management remains a significant economic and sustainability problem and is being actively addressed by scholars, governments, and organizations around the world. Bioplastics, which are biodegradable plastics derived from food waste, are a recent innovation that might contribute to managing this waste in a more sustainable manner. Unfortunately, many of today's consumers are not necessarily ready to consider such alternatives. Consumer switching to sustainable products is a tenuous topic, as consumers often value other product attributes (i.e., cost, quality, and associated prestige) more than their sustainability attributes (i.e., fewer natural resources expended, lower carbon footprints, and end-of-life recoverability). A greater understanding of consumers' intention to switch to bioplastic products provides opportunities for firms to develop state-of-the-art, profitable, and sustainable food systems. Considering the complex set of inter-relationships surrounding consumer involvement in sustainable innovations and associated supply chain strategy, this research leverages complexity theory and a qualitative comparative analysis research approach to uncover eight different, yet equifinal, configurations of antecedents that motivate consumer intention to switch from new plastic products to equivalent products made from bioplastics.     

Nigeria's food situation: Problems and prospects

The authors review the food situation in Nigeria and examine the problems and prospects of food grain production in the country. Suggestions are made on how to improve food supply, prominent among which are improved production practices for grains and the development of appropriate infrastructural support systems.     

A theory-based evaluation of food waste policy: Evidence from Italy

Italy recently reformed its food waste policy by introducing innovative measures, such as the possibility of donating food after the best-before date (BBD) and a significant simplification of the bureaucracy of donations. These measures are advocated by food waste specialists and are thought to increase donations almost automatically. The article performs a theory-based evaluation using the method of realist synthesis to investigate the two measures, test their implicit assumptions, and provide a more complete picture of how the policy works. The results highlight the marginal importance of bureaucratic procedures in the cost structure of donations, the diverse responses of different donors and food rescue organisations, and the importance of considering the capacity and preferences of charities when an increase in donations is expected. Further, the analysis uncovers severe reputational risks that limit both the supply of and demand for food past the BBD, despite legal provisions promoting its donation.     

The household wasteful behaviour framework: A systematic review of consumer food waste

Every year one third of the food produced globally is either lost or wasted along the food supply chain (FSC) causing significant economic, environmental and social damages. In the developed countries household food waste is a major concern, which is manly triggered by poor food-related behaviour. Due to the importance and magnitude of the phenomenon, the UN has set the global goal of halving food loss and waste by 2030. However, to the best of our knowledge, to date no systematic literature review has been conducted on household food waste and little comprehensive explanation has yet been offered for wasteful household behaviour. Therefore, the aim of this study was to carry out a systematic review of the literature produced over an eighteen-year period (2000–2018) in order to gain a deeper understanding of multiple, complex facets of the food waste phenomenon at consumer level. Drawing on the results of the systematic literature review and of the behavioural and marketing theories, we propose a new theoretical framework “The Household Wasteful Behaviour Framework”, with the aim of better explaining food waste behaviour at household level. Results can be useful to better target social norm and educational campaigns both at private and public level.
