Food waste reduction towards food sector sustainability

FAO estimates on average more than 1.3 billion tons of food loss and waste (FLW) along the whole food supply chain (equivalent to one-third of total food production) of which more than 670 million tons in developed countries and approximately 630 million tons in developing ones, showing wide differences between countries. In particular, EU data estimates an amount of more than 85 million tons of FLW, equal to approximately 20% of total food production. This research presents two main goals. First, to review the magnitude of FLW at a global and European level and its environmental, social and economic implications. Second, use Material Flow Analysis (MFA) to support and improve FLW management and its application in an Italian potato industry case study. According to the case study presented, MFA has demonstrated the advantages of tracking input and output to prevent FLW and how they provide economic, social, and environmental opportunities.
