Abstract
PurposeThe study proposes Material Flow Analysis (MFA) methodology as a tool to measure and qualify food waste in the Italian beef supply chain in each stage of the food supply chain, from farm to fork. In particular, the authors attempt to: (1) measure resources consumption and waste generation toward companies' and policymakers' sustainable evaluations; (2) enhance consumers' education in the field of agri-food resilience and sustainability.Design/methodology/approachMFA is applied to the entire Italian sector of beef consumed as packaged fresh product in 2020, during the Covid-19 pandemic. The analysis regards bovine, which represent roughly one-third of the national meat flow. To collect data, bottom-up and top-down mixed approach is applied. Subsequently, MFA results are used to calculate the wastage-related losses in terms of embedded natural resources (e.g. water, energy).FindingsIn 2020, it results that the Italian meat industry slaughtered more than 1.15 Mt of bovine to produce approximately 0.29 Mt of fresh meat, 0.69 Mt of by-products and over 0.015 Mt of food waste at households, while 0.15 Mt of beef meat is destined to catering services and food industry (out-of-boundaries). In terms of hidden natural resources, it emerged that, on average, more than 94bn m3 of water, approximately 101,000 TJ of energy and over 11,500 t of PET and PE trays are required to sustain the entire beef system.Originality/valueThis research is one of the few studies proposing MFA methodology as a tool to measure food waste and hidden associated flows in the agri-food sector. This analysis shows its utility in terms of natural resources (water, energy, materials) and waste quality/quantity evaluation, hidden flows accounting and development of new educational strategies toward food waste minimization and sustainability at household consumption.
Highlights
The Italian meat industry, which accounts for over 15% (20bn euro) of the domestic agri-food value (ISMEA, 2019a, b, c), represents a core business for the national economy, but requires huge amounts of natural resources and generates different typologies of waste, from food waste to packaging (Djekic and Tomasevic, 2016)
The application of the mass balance approach, essential to better understand the Italian beef supply chain metabolism and to highlight hidden and/or virtual material flows associated to foods, helps: (1) to measure resources consumption and waste generation toward companies’ and policymakers’ sustainable evaluations; and (2) to enhance consumers’ education in the field of agri-food resilience and sustainability
The present research, through the application of the Material Flow Analysis (MFA) to the entire Italian beef system, assessed that, in 2020, more than 1.15 Mt of bovine have been slaughtered to produce approximately 0.29 Mt of fresh meat, 0.69 Mt of by-products and over 0.015 Mt of food waste at households, while 0.15 Mt of beef meat has been allocated to catering services and food industry
