Abstract [en]

The United Nations sustainability goal SDG 12.3 is to reduce the amount of food that is wasted by half, due to environmental and social reasons. This paper aims to analyse the most important packaging functions that affect food waste in households for different products, as the reason for wastage can be expected to differ between different products. The reasons for food wastage of different categories and products have been compiled through literature studies, and possible improvements of packaging functions to reduce food waste have been identified. In addition, an expert workshop judged the most important packaging functions to reduce food waste for a number of products. They also discussed the obstacles and possibilities to realise the packaging improvements. This study confirms that how packaging functions influence food waste on the product level is a highly unexplored question. Most likely, there is high potential to reduce food waste through better adaptions of packaging functions to user needs and habits. Both the literature study and the expert workshop show that less food per pack and better information regarding food safety and storage have high potential to reduce food waste, but also that product specific considerations are necessary.
