A Social Innovation Model for Reducing Food Waste: The Case Study of an Italian Non-Profit Organization

A Social Innovation Model for Sustainable Development: A Case Study of a Malaysian Entrepreneur Cooperative (KOKULAC)

In Malaysia, social innovation programs are fully supported by the government. However, reports and findings on the related matter have yet to be comprehensively collected due to the current interest. Therefore, the aim of this paper was to provide a better insight and understanding on how social innovation projects could assist in achieving the SDG agenda. Since social innovation is emerging and has just recently been embraced in Malaysia, we present the study as a case based on an entrepreneur cooperative, named KOKULAC, with a grounded theory analysis as a core approach. The findings suggest that there are five sustainability development goals that are very closely related to KOKULAC’s agenda. These goals are no poverty, zero hunger, decent work and economic growth, responsible consumption and production, and partnership for the goals. In addition, the case also presented how the values of sustainable development spur greater social benefits of shared prosperity. We conclude that the proposed model contributes to the expansion of innovation capability theory by shaping the innovations within the scope of social needs, which could be applied in other settings. For future research, we recommend a higher integration between the social innovation model and dynamic capabilities of the networking structures.

Using blockchain technology to drive operational excellence in perishable food supply chains during outbreaks

Purpose

This paper aims to explore the potential of blockchain technology (BT) to support the operational excellence in perishable food supply chain (PFSC) during outbreaks, by doing use-case analysis.

Design/methodology/approach

A systematic literature review is performed to determine the dimensions of operational excellence in the food supply chain (FSC), then a single use-case analysis is conducted to explore the potential of blockchain in order to achieve operational excellence for PFSC during the pandemics by applying context, interventions, mechanism and outcomes (CIMO) logic.

Findings

The findings of this study reveal that blockchain capabilities such as immutability and transparency, visibility, traceability, integration and interoperability, disintermediation and decentralisation, smart contracts and consensus mechanism provide better sustainable operational excellence outcomes for PFSCs to be more responsive, flexible, efficient and collaborative to cope with the impacts of COVID-19.

Research limitations/implications

This research employs only one real case with multiple PFSC participants. Statistical generalisation is not possible at this stage of the research. However, the findings are not restricted to this single use-case.

Practical implications

This study provides a research direction to explore the potential of BT to achieve operational excellence in the PFSC during outbreaks and generates prescriptive knowledge for better managerial decision-making across the PFSC during outbreaks.

Originality/value

This research conducts semi-structured interviews with different participants in one blockchain ecosystem to understand multiple participants' perspectives of operational excellence within PFSC.

Simulation of Crop Yields Grown under Agro-Photovoltaic Panels: A Case Study in Chonnam Province, South Korea

Agro-photovoltaic systems are of interest to the agricultural industry because they can produce both electricity and crops in the same farm field. In this study, we aimed to simulate staple crop yields under agro-photovoltaic panels (AVP) based on the calibration of crop models in the decision support system for agricultural technology (DSSAT) 4.6 package. We reproduced yield data of paddy rice, barley, and soybean grown in AVP experimental fields in Bosung and Naju, Chonnam Province, South Korea, using CERES-Rice, CERES-Barley, and CROPGRO-Soybean models. A geospatial crop simulation modeling (GCSM) system, developed using the crop models, was then applied to simulate the regional variations in crop yield according to solar radiation reduction scenarios. Simulated crop yields agreed with the corresponding measured crop yields with root mean squared errors of 0.29-ton ha−1 for paddy rice, 0.46-ton ha−1 for barley, and 0.31-ton ha−1 for soybean, showing no significant differences according to paired sample t-tests. We also demonstrated that the GCSM system could effectively simulate spatiotemporal variations in crop yields due to the solar radiation reduction regimes. An additional advancement in the GCSM design could help prepare a sustainable adaption strategy and understand future food supply insecurity.

Opportunities for and Limits to Cooperation between School and Families in Sustainable Public Food Procurement

This paper describes a research project, carried out in an Italian public school, to assess whether parents were willing to take part in food procurement decisions, as well as their ability to accurately predict what foods children would pick at school lunch and their propensity to support sustainable food choices made by the school. The methodology included a questionnaire, issued to 500 parents, and an in-depth study of 138 child/parent pairs. The study comprised: (i) presentation of an innovative recipe in the weekly menu of the school canteen; (ii) meal observations of children’s intake at school lunch during the week of the menu modification; (iii) collection of both parents’ and children’s reports on their choices of recipes from the modified weekly menu. The results are commented in light of two important changes that have recently affected Italian public school food procurement: the opening of school canteens to lunches brought from home and the measures adopted since 2020 to contain the COVID-19 pandemic. Both events go in the direction of delegating to parents the multifaceted role of the school in the food arena. The article concludes that the results of the study should discourage this approach.

Synergistic Interactions of SDGs in Food Supply Chains: A Review of Responsible Consumption and Production

In light of the significance of Food Supply Chains (FSCs) in attaining the United Nations’ 17 Sustainable Development Goals (SDGs), a greater focus on synergistic interactions between these SDGs is called for. Although there is research within this area, the impact on the interactions of responsible consumption and production for supply chains is either fragmented or inconclusive. Implementing supply chain solutions to achieve one goal could potentially support or inhibit progress in other goals; thus, before implementing such solutions, a better understanding of the interrelationships between SDGs is required. A systematic review is conducted to evidence the current nature of the understanding of these interrelationships within the food supply chain context by focusing on Responsible Consumption and Production, which refers to SDG number 12. This review is conducted through a filtering process, where 171 peer-reviewed articles addressing different SDGs were analysed and synthesized. In addition to a detailed summary of the recent literature on the SDGs and their interrelationships, as addressed in the literature, this paper establishes the limitations in the existing literature and research challenges surrounding the SDGs. This article contributes a conceptual framework that identifies stakeholder and consumer pressures as enablers of synergistic interactions between SDGs, thus directing managerial and regulatory interventions through a holistic perspective of SDGs. Finally, the review discusses contradictory findings on SDGs and provides future research avenues.

A systematic literature review on food waste/loss prevention and minimization methods

Several initiatives have been proposed to address food waste and loss issues and support stakeholders throughout the food chain. However, the literature still lacks a review paper that compiles methods, practices, and solutions to reduce food waste and loss. With the goal of filling this gap, this paper aims to compile and gather food waste and loss prevention and minimization methods to support decision-makers and other stakeholders along the food chain. Through a systematic literature review, we have outlined research findings and empirical studies on food waste and loss prevention and minimization methods previously published, studied, implemented, and discussed in the scientific literature worldwide. A sample of 84 articles was analyzed. As a result, this study provides a bibliometric analysis of the sample and a classification of the prevention and minimization methods found in the articles in 10 fields established by the authors. A coverage analysis of empirical studies was also performed, cross-checking the data with the type of food extracted from the case studies application. Lastly, suggestions of future research extracted from the articles were compiled into a research agenda to indicate trends and support academics, researchers, practitioners, and other stakeholders involved in the food chain to develop and study practices to minimize and prevent food waste and loss. The main contribution of this study is an inventory of the theoretical and practical methods of prevention and minimization of food waste and loss found in the literature, grouping them according to their similarities, to support stakeholders improving actions to reduce food waste in cities, farms, retail, and other sustainable ecosystems.

A Hierarchical Pyramid for Food Waste Based on a Social Innovation Perspective

Food waste (FW) represents one of the greatest concerns facing mankind today; thus, the UN Agenda 2030 for Sustainable Development establishes that it must be halved by 2030. European Union legislators have taken part in this debate by publishing Directive 2018/851 to monitor the FW reduction goals, according to the waste hierarchical pyramid approach. At present, there are several proposed FW hierarchical pyramids, but these do not regard the associations between the level of waste-tackling strategies and social innovation (SI) models. Thus, the paper aims to build a hierarchical pyramid that considers, for each step of the food-supply chain and each level of the pyramid, all the FW social innovation models. A qualitative analysis of academic studies, institutional documents, and specific projects has been conducted. The results confirm the gap in the scientific literature and the lack of a systematic classification of SI activities to reduce FW. Furthermore, current SI practices are actually more focused on the human reuse of FW than on prevention, whereas SI models based on prevention might return the FWL issue to its systematic dimension. This information will help policymakers to reconsider the structural causes of FW inside the agro-food system, and not only its final consequences.

Intention to Purchase Active and Intelligent Packaging to Reduce Household Food Waste: Evidence from Italian Consumers

Innovations in food packaging, such as active and intelligent ones, improve food safety and lower household food waste by extending product shelf life and providing information about food quality, respectively. The consumer adoption of such innovations could contribute to reaching one of the Sustainable Development Goals which calls for halving the per capita global food waste by 2030. Thus, this paper aims to investigate the consumers’ willingness to purchase active and intelligent packaging to reduce household food waste using a sample of 260 Italian consumers and a modified Theory of Planned Behavior (TPB) model. Using a structural equation model, findings show that respondents are more willing to purchase intelligent packaging rather than active packaging to reduce their wastes at home. Finally, attitudes, perceived behavioral control, awareness, and planning routines are the most important drivers of the intention to reduce household food waste.

Households’ Food Waste Behavior at Local Scale: A Cluster Analysis after the COVID-19 Lockdown

The reduction of food waste, especially in households where more than half of its global quantity is generated, has become an increasing economic, social and environmental concern, and represents one of the 17 Sustainable Development Goals within the Agenda 2030 for Sustainable Development. In this context, the COVID-19 lockdown has significantly changed life, work and food consumption habits all over the world, highlighting food waste as a multi-sectorial issue. This paper explores current attitudes, perception and behavioral patterns related to food waste reduction at domestic consumption at the local scale (Apulia region, Italy), with the aim of identifying different types of “food wasters”. Through an online questionnaire and the application of a k-means clustering model, the authors focus on four emerging constructs in terms of food consumption and food waste habits after the COVID-19 lockdown at household level. Among three theoretical clusters, results have highlighted: (i) the paradox of the “green wasters”, which declared a high level of awareness of the food waste issue but also generates huge amounts of thrown away food; (ii) the “positive unawareness” of the “red wasters”, which have a slight notion of environment and sustainability but waste low quantities of food; (iii) the consistency of the “blue wasters”, which know of the food waste issue and convert theory into practice.

Packaging Innovations to Reduce Food Loss and Waste: Are Italian Manufacturers Willing to Invest?

The target 12.3 of the 2030 Agenda by the United Nations (UN) calls for halving per capita global food loss and waste. In this regard, the Food & Drink industry (F&D) could play a crucial role in reducing food waste and improving food safety by adopting healthy and eco-innovation packaging. Thus, this paper aims to investigate the F&D manufacturers’ willingness to invest in packaging innovations, such as active, intelligent, and compostable ones to achieve the UN target. In order to reach the stated objective, a multiple case study methodology was developed and administered to a sample of Italian micro and small-medium entrepreneurs located in the Apulia region. Results show that many firms were aware of their need for packaging innovation and of the available technological opportunity. However, only the F&D manufacturers who showed a Real demand, according to a taxonomy approach which also considers the Potential and Latent demand for the innovation, were effectively prompt to invest. Finally, most of the interviewed manufacturers were willing to invest in at least one packaging innovation, choosing mainly between the active packaging and the compostable one.

Food Waste Behavior among Romanian Consumers: A Cluster Analysis

The main objective of the current study was to conduct an investigation at the national level in order to identify types of consumers depending on their perception of food waste. To do this, an online survey was carried out on a sample of 2541 respondents. Using a K-means clustering model, three clusters of consumers were identified. Cluster 1, “Careless”, consumers who dispose of food and food waste carelessly, are people who come from rural areas or small cities and have a rather low level of education. They do not have much information on the subject of food waste and do not seem to consider it “a problem”. Cluster 2, “Precautious”, composed of responsible people who do not throw away food, are well-informed and consider that all actors in the agri-food chain have a share in the food waste problem. Those who belong to cluster 3, “Ignorant”, are mostly from urban areas and have a high level of education. They were not raised to prevent food waste and therefore lack such habits as adults. They have a fair awareness of this subject, but they do not consider themselves responsible for food waste. The results obtained indicate the need to continue the awareness and education campaigns initiated at governmental and civil society level.
