Household Food Waste is deemed to be the highest quota of Food Waste along the food supply chain.... more Household Food Waste is deemed to be the highest quota of Food Waste along the food supply chain. Even though its recoverability is lower than in any other step of the supply chain, most of the studies focus their attention on consumer behavior, both in shopping habits and norms, beliefs and attitudes. Some commentators argue that buying discounted food (Buy One Get One Free or 50% discount due to a close expiry date) may increase the food waste quota per household; however, this evidence has been showed only through the use of questionnaires. If such a hypothesis would be confirmed, the effect of discounting food at retailing level could reveal an unpleasant reverse side: reducing food waste at retail to increase its quota at household level. The aim of the present paper is to analyze whether there is a correlation between the habit of buying discounted products and the weekly food waste quantity at household. The average food waste quantity is estimated through a food waste diary filled out for one week, in March, 2017. The shopping habits, specifically those aimed at inquiring into the issue of buying more food (just or mainly) because it is discounted, is enquired through the use of two specific questions inserted in a 22 questions CAWI survey; the CAWI has been carried out two weeks after the end of the diary phase and it was addressed to the same families that attended the diary study, specifically 420 units widespread in Italy. In this paper, we will consider a preliminary sample of 75 families. Whether such studies in literature are confirmed, we are supposed to find a positive correlation between the habit of buying discounted food and food waste quantity. Nevertheless, considering the limited sample size of the present study, results are to be considered only propaedeutic to incoming analysis of consumer behavior performed on the basis of the same experiment.
