Our research provides solutions to alleviate the economic problems currently plaguing our planet that are responsible for the decline of its ecological systems. Our motivation is the need to identify elements that will encourage and accelerate the transition from a linear to a circular economic model, raising awareness of the limited nature of resources and the major pressures exerted by climate change and population growth. Our paper highlights the implications of strategic thinking, i.e., strategic management, in the development and promotion of the circular economy, including the concept of sustainability, in the agri-food sector. We propose strategic options based on information from our secondary analysis of statistical data and relevant literature, e.g., from PESTEL, SWOT, and DPSIR diagnostic models, for integrating resource flows into circular processes, which are meant to reduce resource consumption and minimise waste. Our paper elaborates on an integrated and dynamic model for the transition from a linear to a circular economic model; furthermore, we perform further research to create appropriate frameworks for elaborating on and implementing the most relevant policy options to accelerate this transition process.
