Linkage between delivery frequency and food waste: Multiple case studies of a norwegian retail chain

Abstract

The main objective of this paper is to investigate linkage between delivery frequency and food waste of chilled products by testing the hypothesis-the higher the delivery frequency, the lower the food waste. Multiple case studies have been used to test the hypothesis. Food waste ratios of five product groups have been compared in three delivery frequency scenarios, namely low delivery frequency, medium delivery frequency and high delivery frequency scenario. Moreover, food waste ratios of different product groups have been compared to each other within each delivery frequency scenario. The findings show a strong negative correlation between delivery frequency and the food waste ratio for each investigated product group, which supports the hypothesis. On the other hand, food waste ratios among different product groups within the same delivery frequency scenarios vary significantly.
