Goals. This Bachelor’s Thesis’ goal was to find out how supermarkets’ groceries-in-sale have influence on the amount of produced food waste in households. This subject is topical because in 2015 in Helsinki metropolitan area S-ryhmä started a campaign, where they sell products, which have best before and expiry date nearby, with double discount after 9pm. In the autumn of 2017 these sales expanded to whole of Finland. With this research, the reasons behind throwing away food would like to be found out and how different transforms like age and education affect the food wasting. Also, the effect of deep-freezing on the amount of food waste is studied. Methods. The thesis was conducted as a quantitative research. The material was collected by a survey in e-form. 38 respondents were gotten, from which there were 31 women and 7 men. The link to the survey was shared via Facebook group called Järvenpää-ryhmä. As a sampling method, self-selected sample was used. Analysis was done in Excel, using cross tabulation and percentages. Results and conclusions. According to the results of the thesis, those who participated in the survey bought 1-5 sales items at a time. Buying was almost always an impulse purchase. According to the results, most of the participants (79%) did not throw food away at all. This could be explained by the fact that they bought only few things (1-5 items) at a time or if they bought more they might deep-freeze it. The biggest reasons on why they threw food away were that the best before date had already gone or food was left over on the plate. According to the results, a relation between deep-freezing and food waste was found. The more people deep-freeze the less they waste food. These results can be used as a starting point for a more comprehensive study. The results and conclusions in this study are directional due to the small sampling. In order to be able to universalize these results, further research on the matter is needed.
