In recent years, researchers and practitioners have increasingly paid attention to food waste, which is seen as highly unethical given its negative environmental and societal implications. Waste recovery is dependent on the creation of connections along the supply chain, so that actors with goods at risk of becoming waste can transfer them to those who may be able to use them as inputs or for their own consumption. Such waste recovery is, however, often hampered by what we call 'circularity holes', i.e., missing linkages between waste generators and potential receivers. A new type of actor, the digital platform organization, has recently taken on a brokerage function to bridge circularity holes, particularly in the food supply chain. Yet, extant literature has overlooked this novel type of brokerage that exploits digital technology for the transfer and recovery of discarded resources between supply chain actors. Our study investigates this actor, conceptualized as a 'circularity broker', and thus unites network research and circular supply chain research. Focusing on the food supply chain, we adopt an interpretive inductive theory-building approach to uncover how platform organizations foster the recovery of waste by bridging circularity holes. We identify and explicate six brokerage roles, i.e., connecting, informing, protecting, mobilizing, integrating and measuring, and discuss them in relation to extant literature, highlighting novelties compared to earlier studies. The final section reflects on contributions, implications, limitations and areas for further research.

Purpose The purpose of this paper is to explore the potential impact of food sharing platform business models and to identify the limits and barriers in measuring the impact. Using the “theory of change” (ToC) approach, this paper develops a theoretical framework that captures the activities, outputs and outcomes of food sharing platforms and links them to indicators. Design/methodology/approach The study employs a two-step methodology, which includes a website content analysis followed by two focus groups. The purpose of the website content analysis was to list a set of activities that are performed by food sharing platforms. The focus groups allow to design the ToC and to discuss limits and barriers in measuring the impact of food sharing platforms. Findings The study provides an overview of the main areas of impact of food sharing platforms (environmental, social, economic and political) and identifies the related outcomes. Furthermore, the paper highlights the need for the platform to manage the multifaceted tensions of food waste recovery vs prevention and the benefits of food recovery to helping hungry people vs the actual need to eradicate poverty by addressing social injustices and inequalities. Research limitations/implications The selected sample involved in the focus group comprised a wide but not comprehensive set of stakeholders. Indeed, the obtained information cannot be generalized. In addition, the ToC approach requires a certain discretion of the facilitator and introduces the potential for partiality in conducting the analysis. Practical implications The framework helps to unbundle the complex challenge of measuring the impact of food sharing platforms and it provides managers, practitioners and policy makers with a practical tool to direct their activities toward a better impact. Originality/value From a theoretical perspective the study advances the literature on (food) sharing platforms and contributes to research on the sustainability in the food sector. It indicates the impacts a novel actor relying on digital technology can have in the food sector and points out the tensions between food recovery and prevention and the impact on poverty. The proposed framework could be a useful tool to support practitioners in understanding the trade-offs among the outcomes they aim to attain, and to identify the proper strategies to manage them.

This article ties in directly with recently intensified interest in business models in international business (IB), using the energy transition as empirical context to explore their relevance in firm internationalization. The global energy transition presents a challenge for almost all industries, but some face specific difficulties particularly important from an IB perspective. We study a set of European firms that used to operate in a highly regulated context with (partial) state ownership, until government-directed market liberalization started to allow further competition and internationalization. Existing firms were prompted to adapt their business models to these changes, with new ventures entering the market to reap opportunities with novel energy-related technologies and business models. Linking insights from strategic management to the IB literature, we conceptualize business model-related specific advantages (BMSAs), and explore the role of BMSAs in the internationalization of the firms in our sample. We also uncover barriers to BMSA recombination in (potential) host countries, consider BMSA location-boundedness, and discuss implications for firms’ international expansion by presenting a new framework. Consequences for the energy transition and the actors already involved and (in)directly confronted with it are explicated, while outlining promising areas for further research, building on the insights and limitations of our study.
