Background/Rationale

The No Waste? Know More! project aimed to valorize food loss and waste (FLW) potential in the retail sector to enhance practices and behaviour to boost circular economy opportunities in the Canadian food system. Design/Methods are presented in this paper, namely, detailing the complementary developmental mixed methodology: (1) the scope of the literature review, (2) a mapping exercise of literature findings, (3) interviews of key stakeholders from industry, food redistribution groups, and policymakers, (4) a survey of food buyers within the retail sector, and (5) participatory design workshops. Further, we employed a transdisciplinary approach at various points in the project to obtain intersectional insights. Results revealed retail practices that both exacerbate detrimental practices and enable innovations on FLW reduction, circularity, and engagement in the circular economy. Key insights from each step of the complementary method are highlighted. These include identified meaningful ways to close loops towards optimizing circular food economies, strategies to prevent or reduce FLW parallel interventions that improve diet quality across socioeconomic divides, enhance wellbeing of populations, reduce healthcare expenditures, and enhance sustainability of natural resources through engagement in a circular food system. Discussion: The transdisciplinary approach to understanding the current FLW at the retail level informs strategies to identifying how to scale up innovations and provide concrete recommendations to address behavioural challenges and policy directions for retailers in reducing waste in the context of health, economics/accounting, agriculture, and the multiple complex steps along the supply chain.
