Matavfall från matvarubutiker i Umeå : Möjligheter till källsortering och minskat svinn

Title: Food waste from grocery stores in Umeå- the potential for taking care of and reducing the amount of food waste. Author: Helene Myhrberg Abstract Food waste from grocery stores is an increasing problem in Sweden, and amounts to roughly 67 000 ton per year. This has consequences both for sustainability in general, but also for achieving the targets stipulated by the EU. Given this, it should be relevant for the society that grocery stores both decrease the amount of food waste but also develop better ways of dealing with food waste. Although there exist methods for this, the practicability of such measures are unknown. In this thesis I assess these issues by conducting interviews with owners and employees at five grocery stores in Umeå, asking them how they think about these questions. In particular, I focus on how to take care of and prepare food waste for anaerobic digestion and how to decrease volumes of food waste. In essence, I find that both the knowledge of, and interest in, these issues vary substantially between grocery stores. Further, for these measures to be feasible, it requires the process to be both economically efficient while not requiring too much time of work. With this in mind, it seems necessary to have a facility that can take care of both packed and unpackaged food waste, making it as cheap and simple as possible for the grocery stores. For reducing volumes of waste, most grocery stores agrees on better planning as the way to go. Key words: food waste, grocery stores, anaerobic digestion, decreasing of food waste
