Abstract [en]

The environmental concern and development issues regarding packaging has for 20 years to a high extent been on packaging when it has become waste. To reduce the environmentalimpact from the whole foodpackaging system it is also important to develop the packaging’s ability to reduce food waste. In some cases it may be necessary to increase the environmentalimpactofpackagingin order to reduce food waste. In this paper, the environmentalimpactofpackagingandfoodlossesand the balance between the two has been examined for five different food items. The results show that packaging’s that reduce food waste can be an important tool to reduce the total environmentalimpact, even if there is an increase inimpact from the packaging itself. This is especially true for food items where the environmentalimpactof the food is high relative the packaging, for example cheese, and for food items with high losses, for example bread. It is important to analyse the risk of increasing foodlosses when packaging design changes, for example, when the aim is less packaging material, which is the main intention of the packagingandpackaging waste directive of the European Union.

Abstract [en]

Packaging has been on the environmental agenda for decades. It has been discussed and debated within the society mainly as an environmental problem. Production, distribution and consumption of food and drinks contribute significant to the environmental impact. However, consumers in the EU waste about 20% of the food they buy. The function of packaging in reducing the amount of food losses is an important but often neglected environmental issue.

This thesis focuses on the functions of packaging that can be used to preserve resources efficiently and reduce the environmental impact of the food-packaging system. The service perspective is used to increase knowledge about consumer interaction with packages. Fifteen packaging attributes, for example, ‘easy to empty’, ‘hygienic’ and ‘contain the right quantity’, were identified as influencing the amount of food losses at the consumer. The result showed that there are potentials to both increase consumer satisfaction and decrease the environmental impact of the food-packaging system, when new packaging design reduces food losses. A model was developed that calculates the balance of environmental impact between reduction of food losses, and more packaging material. The result showed that it can be environmentally motivated to increase the environmental impact of packaging, if the amount of food losses is reduced. This is especially true for food items with high environmental impact, e.g. meat and dairy products, and for food items that have a high share of loss, e.g. bread.

I have also explored to what extent packaging can influence food losses in households. The study showed that about 20% to 25% of household food waste was related to packaging. The households noted three packaging attributes as the main causes for food losses; ‘too big packaging’, ‘difficult to empty’ and ‘best-before-date’.

Finally there is a discussion of packaging research in the context of sustainability principles, and suggestions for further research.
