Within the CEFoodCycle project, key data foundations, tools, and practical solutions were developed to support the transition towards a circular and sustainable food system in the Alpine region. Consolidated Alpine-wide LCA datasets, five Circular Food Hubs, and six pilot actions demonstrated how food waste can be reduced and food residues reused and valorised across different stages of the food system, while strengthening stakeholder capacity and collaboration. These results culminated in the development of FoodCycle.ai, a user-centred decision-support tool that increases transparency, supports sustainable decision-making, and provides a scalable basis for long-term impact.
