Comprehensive Measurement of Italian Domestic Food Waste in a European Framework

Food management is an inefficient activity, and households are the major contributors responsible for food waste across the food supply chain. Ten years remain to halve household food waste, as recommended by the 2030 Agenda for Sustainable Development. Up to now, Italian investigations into household food waste have been research activities with limitations in measurement and sampling. The need to establish a monitoring system led the Italian Observatory on Food Surplus, Recovery and Waste to apply a methodology that permits comparison with other European countries. In 2018, a survey involving a representative sample of 1142 Italian households was carried out. The majority of respondents (77%) reported that they had wasted 370 g of food during the last week, evidence in line with data from the Netherlands and progressively different from what was found in Germany, Hungary, and Spain. Perishable products, such as fresh fruit and vegetables, bread, and nonalcoholic drinks, were mainly wasted. The most frequently disposed foods were unused (43.2%) or partly used (30.3%). As for possible causes, household food waste was significantly associated with preventive practices and ability. This study endeavored to segment household food waste based on possible drivers and barriers to preventive action, setting the stage for future monitoring, supporting policy action, and educational intervention.
