Food production represents today an environmental cost, boosting scientific community and food companies searching innovative solutions to reduce environmental impacts and wastes. Among all agri-food supply chains, 65% of global agricultural emissions of CO2 equivalent are produced by livestock and connected activities. Dairy industry produces a multiplier effect of impacts, using a large amount of primary products to obtain relatively little quantity of cheese. In this context, it is clear that food loss is not only a socio-economic problem, but also represents an additional environmental burden to be attributed to the production process. The adoption of circular economy strategies could represent the right way to reduce the issue of food waste and food losses, not only by reusing and/or recycling expired products but also extending the shelf life of edible products, that finally would mean reducing waste and increasing production efficiency (Stillitano et al., 2021). However, the effort of adopting circular strategies risks to become vain if the degree of circularity achieved is not measured, so that a process of continuous improvement can be adopted in a circular design logic. The aim of this study is to evaluate, from a circular, environmental and economic perspective, techniques for the shelf life extension (SLE) of Lacto-Fermented Mozzarella Cheese. Life Cycle Assessment, Circularity Assessment and Life Cycle Costing methodologies were applied to evaluate the effects of SLE implementation, taking also into account the potential reduction of food loss and returned goods. Results showed that despite a minimal increase of impacts and costs due to the introduction of the innovation, the SLE could allow reducing the share of losses up to 50%. Expressing results in terms of days of product shelf life, the innovative solution is more sustainable from both the environmental and the economic point of view and allows an improve
