Lebensmittelabfälle in privaten Haushalten in Deutschland : Analyse der Ergebnisse einer repräsentativen Erhebung 2016/2017 von GfK SE

Abstract

On behalf of the German Ministry of Food and Agriculture, the GfK SE market research company systematically studied the food waste in German private households from July 2016 to June 2017. The study was a representative diary study. Almost 7,000 households were surveyed over a period of two weeks each on their dealings with food waste (FW). The focus of the study was on types and amounts of avoidable and unavoidable food waste. Documented were reasons for disposal, condition of food products and means of elimination. Further differentiation was made on the basis of household size, age of the head of household and his/her education level, and regional location. Essentially this study offers much new information on dealing with food waste in private households in Germany, and is a good basis for the development of new political options to reduce food waste. Particularly information on the type and composition of food waste is revealing. For example, the study found that 16 % of the avoidable FW is 'cooked or prepared' (with a very high energy input). In part however other reasons for disposal are confirmed, and classified according to their relevance for the purposes of this study. One example is the food expiration date: only 5.8 percent of those surveyed refer to this as a reason for disposal, while ten times this number - overall 57.6 % - through food away due to storage problems, and one third of these foodstuffs were already spoiled.
