Institutional work in food waste reduction: Start-ups' role in moving towards a circular economy

Dealing with food waste is a major concern for the food system in the transition towards a circular economy (CE). Previous studies have developed various solutions to address the issue, but the role of for-profit start-ups remains poorly understood. This paper aims to analyse the forms of institutional work conducted by start-ups to prevent and reduce food waste. This paper adopts the multiple case study approach, utilising a three-year netnography of the emerging food waste reduction business and interview data from company representatives. We outline four categories in which the start-ups conduct institutional work: appearance of food, quantity of food, edibility of food, and living with food. The start-ups disrupt existing institutions that lead to food waste, as well as create new institutions to enable and reinforce their business operations. We argue that the start-ups have an influential role in changing the normative and cognitive-cultural institutional pillars in the shift towards a CE. The article provides a contribution to studies on the CE and food waste and has practical implications for both established and start-up businesses.     

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.     

Conceptualizing sustainable diets in Vietnam: Minimum metrics and potential leverage points

A major barrier to achieving sustainable diets is the lack of clearly defined and agreed upon intervention points that will positively influence multiple sectors of the food system. There is an urgent need to understand what policy approaches and interventions will most effectively enhance the sustainability of diets in rapidly urbanizing low- and middle-income countries. To address this need, this work combines the input of diverse stakeholders and analysis of existing datasets to develop a conceptual framework for sustainable diets that is locally relevant to Vietnam using a process that is generalizable to other developing countries. The resulting framework includes 235 unique, measurable indicators within eight domains: (1) food production, (2) food processing and distribution, (3) food loss and waste, (4) food access and consumption, (5) food and water safety, (6) nutrition, (7) sociopolitical context, and (8) environmental impact. This conceptual framework was employed in a participatory workshop that brought together 50 Vietnamese stakeholders from diverse areas of expertise to identify and prioritize specific metrics for measuring sustainable diets. Based on the results of the stakeholder workshop, expert interviews, and characterized datasets, a comprehensive set of minimum metrics for each domain was produced and key leverage points that are likely to have an impact across multiple sectors were identified. These leverage points include food quality and safety, agricultural chemical usage, food waste, and water management. The analysis is expected to contribute to evidence-based policymaking in Vietnam to cultivate more sustainable diets.     

Reducing food waste in hotel kitchens based on self-reported data

This study provides insights into the effects of self-reporting on food waste generated in hotel kitchens, and its potential for reducing waste. As a case study, we focus on the generation of breakfast buffet leftovers in four hotels in Germany. To facilitate the self-reporting, we developed a food waste tracking system, which was operated by staff members of the pilot kitchens over 12 months. The self-reporting intervention contributed to improving operational kitchen processes such as refilling the breakfast buffet with less food prepared just-in-time, particularly during the last 30 min of the breakfast time. The self-reported quantities decreased during the first five months of the investigation period and then remained almost constant at a relatively low level. Breakfast buffet leftovers were reduced on average by more than 64.3% of mass, which correlates to annual monetary savings of approximately EUR 9000 per kitchen. The findings of our study demonstrated that breakfast buffet leftovers can be reduced significantly by simple changes and small improvements in daily kitchen routines. However, further research is needed to assess whether self-reporting interventions also contribute to reducing food waste for other types of buffets and food services.     

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.     

Food-away-from-home plate waste in China: Preference for variety and quantity

China is observing a rapid increase of food-away-from-home (FAFH) plate waste along with economic growth. Food waste reduces food use efficiency, exerts pressure on environment and resources, and threatens national food security. This study analyzes the impact of consumers’ preference for variety and restaurants’ dish portions on FAFH plate waste using a survey data from 170 restaurants in Beijing and Lhasa. The primary findings are that higher food variety leads to less plate waste and bigger portion size results in more plate waste. We also observe that increases in consumers’ income lead to more plate waste. Moreover, the Chinese Face-culture plays a significant role on consumers’ plate waste. Serving dishes with suitable portions in restaurants should be incentivized to help reduce both the amount and rate of plate waste. Our results can suggest relevant policy tools to nudge people in forming sustainable consumption behavior and provide valuable implications for reducing food waste and improving food security in China.     

Viewpoint: Future of food safety and nutrition - Seeking win-wins,coping with trade-offs

The possible implications of global trends such as climate change and resource scarcity on food security are high on the political agendas. While the food sufficiency aspect of food security takes centre-stage, the future of food safety and nutritional quality of diets often seems to be taken for granted. This paper builds on the results of a foresight study on EU food safety and nutrition towards 2050 to discuss potential future points of tension for food policy. Increasing food production while using fewer resources and reducing food waste while ensuring food safety are just two examples. Innovation at different levels in the food system will be needed to address future challenges. Fast technology uptake and the launch of new food-related products can put pressure on the ability to deliver timely risk assessments, the scope of which might also need to cover other legitimate factors. Future food policies need to be more sensitive to impacts on food safety and nutrition and health aspects. A holistic food systems approach must be taken to identify and discuss in advance possible tensions and trade-offs and to address them upfront in a systematic and transparent manner.     

Household food security in semi-arid Africa—the contribution of participatory adaptive research and development to rural livelihoods in Eastern Kenya

The already precarious household food-security situation in many semi-arid areas of Africa may be rendered more so through the implementation of structural adjustment programmes that frequently prescribe austerity measures, along with a safety net to protect the vulnerable. However, longer-term development policy perspectives on the one hand, and shorter-term food-relief considerations on the other, often conflict. This paper illuminates the policy conflicts which arise when local-level research and development initiatives interface with the effects of macro-policy-initiated changes and safety-net interventions. Using a participatory agricultural research project in Eastern Kenya as a case study, the paper describes specific household food-security problem diagnosis and a range of research interventions planned within a more sustainable rural livelihoods framework. Working with local farmers, the project implemented a range of applied research and linked development interventions that showed promise in easing food security through a broadening of the livelihood base. Some of these initiatives were carried further through the local farmers' own initiative. The conclusion is that semi-arid areas, despite views that see these as low-potential and obvious safety-net candidates, often have potential for agricultural intensification and increased productivity. However, to ensure that research results are utilised and farmers have access to new technology and markets, there is a need for external or public-sector support to integrated longer-term development initiatives. This may require rethinking the scope of research and development approaches, particularly removing unhelpful boundaries between research, extension and development functions, and increasing farmer participation in the whole process—if possible as part of a less centralised and more household-oriented approach to food-security policy and strategy.     

Restructuring existing value networks to diffuse sustainable innovations in food packaging

Sustainable innovations in food packaging are important in terms of preventing food waste and reducing environmental impact, but existing industry regimes and networks may hinder their diffusion into established markets. However, research on reorientation of existing industries, and value networks in that situation, has been limited. This study examines the changes to existing industry value networks that can facilitate the diffusion of sustainable innovation in food packaging. Empirically, the transformation and distribution of agro-food waste into a new bioplastic packaging through the existing food packaging value network is investigated. As a result, the changes to the existing value network and their connections, facilitating the diffusion of the sustainable innovation, are identified at three levels – firm, network, and macro. The findings show the importance of opportunity recognition, but also the role of new actors, resources, activities, and relationships in the restructuring of the existing value network and actions creating supportive regulative framework and increasing market demand for such renewal. This creates understanding of how the adoption of sustainable innovations, such as new packaging materials, which might seem simple, is complicated by the broad changes required from the existing value network.     

Where are the best opportunities for reducing greenhouse gas emissions in the food system (including the food chain)? A comment

In a recent paper Garnett (2011) examines the greenhouse gas emissions arising from the global food system. This paper builds on Garnett’s contribution by considering how high levels of food waste contribute to the food chain’s greenhouse emissions and how they can be reduced, something Garnett generally overlooks. The emissions that arise from food waste represent the emissions embedded in the production of food that is then wasted and the emissions that arise from the process of waste disposal. Food waste can also be split into pre-consumer and consumer waste. These distinctions give rise to four categories of food waste related emissions: pre-consumer embedded, pre-consumer waste disposal, consumer embedded and consumer waste disposal emissions. The levels of food waste in each category differ between economies, as do the causes of wastage. Policies to address food waste and the associated emissions need to promote a mixture of technological and behavioural change and be tailored to the economic, cultural and technological conditions in each country.     

Urban food policies in German city regions: An overview of key players and policy instruments

Although food is an emerging topic on municipal policy and planning agendas, a systematic examination of policy development, its implementation and the instruments used at the urban level is lacking. This study was carried out with the aim of gaining new insights into the prevalence of certain food policy instruments and capacity of policy action. In order to do so, we developed an analytical framework to investigate urban policy and planning approaches related to food issues and applied it in ten large German cities. First, we identified different actor groups and analysed their role in urban food policy (level of involvement in municipal food projects). We then studied the variety of policy and planning instruments and their application for different elements in the food system. For the empirical study, we employed a case study approach and utilised data gathering methods of qualitative research, i.e. expert interviews and document analysis. Our empirical findings in the studied cities reveal that urban food policy activities are still very fragmented and often based on individual initiatives within the administration. Integrated urban food policies and their implementation through urban food strategies are still an exception in major cities in Germany. We found that municipal actors follow mainly sectoral approaches, using a wide array of steering instruments, i.e. informational instruments and public procurement policies. However, their capacities for policy implementation remain limited due to missing financial and staffing resources. Accordingly, the potential the urban food system offers for sustainable development through multifunctionality and sectoral integration, is still underexploited.The systematic approach developed in this study may contribute to a better understanding of different policy approaches taken. The applied typology of policy instruments might also be useful for identifying effective ways to implement urban food strategies, to understand mismatches between instruments and different policy domains, levels and administrative units, e.g. at the urban-rural interface, and to design of new policy instruments.     

The relationship between household food waste and food security in Tehran city: The role of urban women in household management

Food loss and waste are some of the most urgent social, economic and environmental issues affecting our planet's sustainability, and it has a direct and indirect impact on food security. Food security is a strategic development issue in Iran. This study aims to investigate the overall prevalence and factors affecting household food security with a novel approach to analyze the relationship between food waste and food security in Tehran city. This study applied the Household Food Insecurity Access Scale (HFIAS) for assessing food insecurity and logistic regression modeling. It was found that 64.2 percent of the households are food secure in Tehran. Results have shown that food waste has a significant negative effect on the food security of households, while marital status, family income, food storage, education and housing asset of family indicated positive significant effects on the food security of households. The results revealed most food waste is related to edible food waste such as bread, cooked rice, cooked pasta, which implies that the reduction of it can contribute to improving food security. In light of the major findings of this study, it is concluded that food waste control can decrease the food insecurity of urban Iranian households. This study is the first attempt to conceptualize and provide empirical evidence that food waste reduction increases food security A significant implication that emerges from this study is that food waste control programs could enhance food security in urban households.     

Unravelling the food literacy puzzle: Evidence from Italy

Food literacy – i.e. the ability to collect, understand, process, and use relevant information to navigate the food system – is a key concept inspiring food policies across the World. While scholars agree in discussing the interplay between individual food literacy skills and the health, social, environmental, political, cultural, and economic aspects of food consumption, evidence on the extent and consequences of limited food literacy is scattered. This paper tries to shed light on this issue, proposing a measurement approach to assess the food literacy skills of a representative sample of the Italian population. The research findings suggest that problematic food literacy is prevailing: elderly, people with low education, and those suffering from financial deprivation are more likely to show limited food literacy. Inadequate food literacy concurs in producing impaired health status. Integrated policy interventions are needed to improve individual food literacy skills and to support the establishment of a just and sustainable food system.     

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.     

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).     

Critical realism in case study research

Case study research is the most popular research method for researchers in industrial marketing. However despite a number of attempts the problem of satisfactorily justifying the use of case research remains. This paper proposes critical realism as a coherent, rigorous and novel philosophical position that not only substantiates case research as a research method but also provides helpful implications for both theoretical development and research process. The article describes the critical realist approach due to Sayer and develops a general application of a critical realist approach to case research. An example of its use in practice is presented using a case study of the development of a buyer-seller relationship after the installation of a new MIS system.     

Reducing food waste and food insecurity in the UK: The architecture of surplus food distribution supply chain in addressing the sustainable development goals (Goal 2 and Goal 12.3) at a city level

The paradox that tonnes of food is wasted while people go hungry has raised concern from national and international authorities. In developed countries, reducing these problems has focused on surplus food distribution as a ‘win-win’ solution contributing to sustainable development goals. While the existing literature acknowledges the role of third-sector organisations, research on the supply chain of surplus food distribution and the coordination among actors is limited. This research explores actors and organisations in the value chain of surplus food distribution at the city level. Based on semi-structured interviews and participant observation, our findings highlight the need for a coordinated effort between actors as an essential arrangement to capture the value of surplus food. Despite the close cooperation, hierarchical power relationships exist between organisations in the supply chain. We unpack challenges in the surplus food supply chain, such as lack of a legislative framework for food donations and organisational sustainability issues that have forced third-sector organisations to work independently to reduce the uncertainties of food quality and quantity. We shed light on the practical implications by highlighting how multiple stakeholders could improve the efficiency of surplus food distribution.     

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.     

Why sustainable and ‘nutritionally correct’ food is not on the agenda: Western Sydney,the moral arts of everyday life and public policy

Within a context of delivering food security into the future, dietary guidelines are being reframed, corporations are replacing unsustainable products, and consumers are being encouraged to become ecological citizens. While there is a growing literature on the food practices of ‘alternative’ consumers, ‘mainstream’ consumers are less well understood. This paper describes qualitative research undertaken in a socio-economically disadvantaged area of Sydney, Australia, which aimed to uncover consumer views towards sustainable and healthy diets. Most participants indicated a discrepancy between their desired and actual behaviours: while they want to support Australian, or local, food producers they gravitate towards cheap and tasty food from ‘anywhere’; and while they associate nutritious food with fresh food, they will buy processed foods which can be less expensive, appeal to children and are prone to less waste. Reflecting mainstream Australian political culture, participants were compromising household food budgets in order to pursue a socially acceptable standard of living (including decent housing, car-reliance). They were also incorporating the pleasure and desires of family members as part of ‘the moral arts of everyday life’. Using social theories of consumption and practice sociology we argue that food choices and practices – easy or not – need to be interpreted as part of the role that consumption plays in political citizenship and moral subjectivity. In the Western Sydney context, food practices are essentially household budget and family nourishment practices rather than nutrition and sustainability practices; a position which is not addressed in the government’s new food policies or wage determination processes.     

Adoption of improved wheat varieties and impacts on household food security in Ethiopia

This article evaluates the impact of the adoption of improved wheat varieties on food security using a recent nationally-representative dataset of over 2000 farm households in Ethiopia. We adopted endogenous switching regression treatment effects complemented with a binary propensity score matching methodology to test robustness and reduced selection bias stemming from both observed and unobserved characteristics. We expand this further with the generalized propensity score (GPS) approach to evaluate the effects of continuous treatment on the response of the outcome variables. We find a consistent result across models indicating that adoption increases food security and farm households that did adopt would also have benefited significantly had they adopted new varieties. This study supports the need for vital investments in agricultural research for major food staples widely consumed by the poor, and efforts to improve access to modern varieties and services. Policies that enhance diffusion and adoption of modern wheat varieties should be central to food security strategies in Ethiopia.
