Food losses and waste are currently at the heart of academic debates, civil society initiatives, and political agendas. This paper investigates food waste in school catering services focusing on six schools located in the municipality of Verona (Italy). It aims to quantify food waste, as a measure of food catering inefficiency, to identify the main causes, and to suggest a set of prevention and reduction interventions. For these purposes food waste is defined as all the products discarded from the food chain while still preserving their nutritional value and complying with safety standards. The work shows a significant level of inefficiency in the school catering services, measured by the amount of food processed and still perfectly edible, but not served during the meals. On average more than 15% of the overall processed food is wasted. Among the causes identified in this study, four of them were more relevant than others because of their implications and impact on prevention: the lack of attention to dietary habits, the rigid food procurement specifications, the menu composition, and the meal presentation.

Reducing food waste is globally considered as a key challenge in developing sustainable food systems. Although most food waste is generated at the household level, consumers hardly recognize their responsibility, and the factors underpinning their perception of the quantity of food wasted at home are still unclear. This paper aims to fill this gap by analyzing the results of a large-scale survey conducted in Italy. The perceived quantity of household food waste was measured through a Likert scale and analyzed by means of a logistic regression against a set of predictors, including food waste motivations, perception of the effects of food waste, and sociodemographic variables. As expected, the perceived quantity of food waste declared by respondents was very low. Among the main determinants, food shopping habits and the level of awareness about the reasons why food is wasted played a key role. In contrast, the perception of the environmental effects of food waste seemed to be less important. Differences among subsamples recruited in different areas of Italy were detected, suggesting that further studies, as well as awareness-raising policies, should also consider context-related variables.

Purpose – The purpose of this paper is to provide insights on the relationships between consumers’ income and household food waste behaviors. Design/methodology/approach – Attitude toward food waste is a paradigmatic (economic) non-standard decision making. Based on behavioral economics concepts and empirical evidences, the study analyzes the frequency of household food waste and its main drivers with a focus on individual income. Through a panel of 1,403 Italian consumers, food waste behavior and its determinants are modeled for five food typologies using proportional odds models that adopt stepwise procedures and genetic algorithms. Findings – Results suggest the existence of complex relationships between per capita income and household food waste behavior. When considering food typologies that include high value added products, this relation can be explained by an inverse U-shaped curve: mid-to-low income consumers purchase higher amounts of lower quality products and waste more food. Research limitations/implications – The research highlights the importance of understanding the main socio-economic and behavioral determinants of household food waste, and the need for further researches. Practical implications – The research motivates specific pricing, commercial and policy strategies as well as organizational technological, and educational solutions to prevent/reduce household food waste. Social implications – Lower income class consumers show a greater attitude to waste certain food typologies. In turn, this implies that food waste can further worse economic inequality and relative poverty. Originality/value – The study identifies different patterns of relationship among individual income and consumers’ food waste behavior, and describes the conditions that limit a household “Food Waste Kuznets Curve.”

Highlights• Household food waste warrants the analysis of the whole consumer's food cycle.• The more upstream is the phase the stronger is the influence on household waste.• The gap between purchasing and outcome leads to additional uncertainty.• Individuals resort to heuristics and deviate from the standard economic model. • Situational factors (food retail) influence food waste generation in homes.
