Abstract(s)

The agri-food sector (AFS) faces challenges in providing affordable and healthy food for an increasing population. In this context, Circular Economy (CE) has gained interest as an approach to drive the food system to sustainability. However, circularity does not always lead to sustainability. The lack of a defined set of metrics to monitor CE in the sector makes it relevant to select assessment approaches that capture CE's contribution to sustainability. For this reason, the present study aims to support the dairy cooperative Fattoria della Piana, a best case of CE, in assessing its circular strategies. The study links Life cycle assessment (LCA) with circularity indicators collected in the literature. This preliminary study analyses the core of the circular exchanges of the cooperative, represented by the anaerobic digestion and combined heat and power plant (AD-CHP) plant. The study presents a valuable assessment approach for companies in the sector, highlighting the complexity of assessing CE. LCA evidenced valuable credits from avoiding mineral fertilizer and natural gas use thanks to their substitution with the treatment plant's outputs. Indicators suggest its ability to recirculate waste for energy purposes and nutrients. Future studies will explore the overall cooperative' system, evaluating the three dimensions of sustainability.
