A major problem throughout the world, food waste is an issue that must be addressed not only by all actors in the agri-food chain but also without a silo mentality. To examine this problem, this article considers the interfaces between the stages of the agri-food chain, by emphasizing the interconnectivity of the different links in the chain, and focusing on the interface between retail distribution and consumption. We show that food waste is socially produced through the interactions and practices of the different actors within food systems. The study presented in this article results from a collaboration research project with two organizations involved in the food waste debate. The data analyzed are derived from an online survey of 1026 Quebec consumers and from 14 semi-directed interviews with retail distribution merchants in the Montreal area, Canada. By identifying, describing and analyzing the consumption and commercial and logistical management practices that contribute to food waste, our analysis demonstrates the existence of four symbolic processes that generate food waste at the retail-consumption interface: the economization of waste, the construction of edibility, the construction of freshness, and the moralization of waste. We argue that these processes should be considered when designing solutions to food waste. This call to consider the interconnectivity of the causes of food waste is particularly important in the field of consumption. Indeed, the major international study on food waste conducted for the Food and Agriculture Organization of the United Nations (FAO) points out that in industrialized countries, 40% of food waste occurs during retail distribution and consumption, but that discarded food is often still fit for consumption [1]. A literature review by Schmidt reports that several studies conducted in Western countries (Germany, United Kingdom, Italy, France, Austria, Switzerland, United States) conclude that households are the chief contributor of food waste and food wastage in general [7]. Such observations tend to place the blame on the consumer, and to build an image of a consumer without conscience or remorse, a participant in the so-called throwaway society [8,9]. Even in research on the causes of waste, approaches that focus on the intrapersonal factors of individual behavior can implicitly reinforce the image of a careless or irrational consumer [10].This article considers the problem of consumption-related waste in light of the concept of the interfaces among the stages of the agri-food chain. By emphasizing the interconnectivity of the different links of the agri-food chain, this concept makes it possible to show that food waste is socially produced through the interactions among and practices of the different actors within food systems. More specifically, the empirical study presented in this article focuses on the interface between retail distribution and consumption. This interface in particular was chosen following the discussions among the researchers and two organizations ...
