Abstract for: Do digitally enabled food sharing platforms matter in a circular economy? A qualitative System Dynamics model for food sharing

Addressing the global challenge of food waste (FW) is crucial for economic, environmental, and social sustainability. Digitally enabled food sharing platforms (FSPs) have emerged as potential solutions, yet their impact remains uncertain. This research investigates the role of FSPs in transitioning towards a circular economy (CE) by analyzing their potential to reduce FW and their unintended consequences, i.e., the rebound effects. Through a literature review and expert interviews, we develop a causal-loop diagram to explore the feedbacks linked to the diffusion and application of FSPs. Our findings highlight the complexities surrounding FSP adoption, including diffusion in urban communities and their real sustainability impact. While FSPs show promise in addressing social inequality and engaging stakeholders, concerns persist regarding their potential to increase consumption and production. This research underscores the need for further investigation into FSPs' role in FW reduction and their broader implications for CE transition. Ultimately, understanding the dynamics of FSPs is essential for maximizing their positive impact on FW while mitigating potential rebound effects.
