Got waste: Knowledge, behavior and self-assessment on food waste of university students in Germany

Abstract

The paper analyzes German students’ interest, perceived importance, knowledge, and behavior regarding food waste. This target group was expected to differ from the general population in terms of food consumption (shopping, cooking, and storage of food) and increased food waste due to their lifestyle. An online survey resulted in 253 participants enrolled in different study programs. Of the sample, 64% studied in life science programs, which were anticipated to have an impact on students’ behavior regarding food. Linear regression models were used to determine the importance of food waste avoidance to students, and their frequency of food disposal. In addition, students were asked about reasons for food waste and assessed statements for each consumption phase. High positive impacts were found for students’ general interest in food waste topics. They attested themselves sensible handling of food products, and rated themselves better than the average German consumer in all surveyed statements. For the target group of university students, detailed knowledge of food waste issues showed little influence on reported behaviors. In conclusion, awareness campaigns, while useful, should not be the only way to target a reduction in food waste, but have to be supplemented by other means.
