Abstract [en]

Summary Thoroughly considering and optimizing packaging systems can avoid food loss and waste. We suggest a number of issues that must be explored and review the associated challenges. Five main issues were recognized through the extensive experience of the authors and engagement of multiple stakeholders. The issues promoted are classified as follows: (1) identify and obtain specific data of packaging functions that influence food waste; (2) understand the total environmental burden of product/package by considering the trade‐off between product protection and preservation and environmental footprint; (3) develop understanding of how these functions should be treated in environmental footprint evaluations; (4) improve packaging design processes to also consider reducing food waste; and (5) analyze stakeholder incentives to reduce food loss and waste. Packaging measures that save food will be important to fulfill the United Nations Sustainable Development goal to halve per capita global food waste at the retail and consumer levels and to reduce food losses along production and supply chains.

Abstract [en]

Purpose: Due to the urgency and the magnitude of the environmental problems caused by food supply chains, it is important that the recommendations for packaging improvements given in life cycle assessment (LCA) studies of food rest on a balanced consideration of all relevant environmental impacts of packaging. The purpose of this article is to analyse the extent to which food LCAs include the indirect environmental impact of packaging in parallel to its direct impact. While the direct environmental impact of food packaging is the impact caused by packaging materials’ production and end-of-life, its indirect environmental impact is caused by its influence on the food product’s life cycle, e.g. by its influence on food waste and on logistical efficiency. Methods: The article presents a review of 32 food LCAs published in peer-reviewed scientific journals over the last decade. The steps of the food product’s life cycle that contribute to the direct and indirect environmental impacts of packaging provide the overall structure of the analytical framework used for the review. Three aspects in the selected food LCAs were analysed: (1) the defined scope of the LCAs, (2) the sensitivity and/or scenario analyses and (3) the conclusions and recommendations. Results and discussion: While in packaging LCA literature, there is a trend towards a more systematic consideration of the indirect environmental impact of packaging, it is unclear how food LCAs handle this aspect. The results of the review show that the choices regarding scope and sensitivities/scenarios made in food LCAs and their conclusions about packaging focus on the direct environmental impact of packaging. While it is clear that not all food LCAs need to analyse packaging in detail, this article identifies opportunities to increase the validity of packaging-related conclusions in food LCAs and provides specific recommendations for packaging-related food LCA methodology. Conclusions: Overall, we conclude that the indirect environmental impact of packaging is insufficiently considered in current food LCA practice. Based on these results, this article calls for a more systematic consideration of the indirect environmental impact of packaging in future food LCAs. In addition, it identifies a need for more packaging research that can provide the empirical data that many food LCA practitioners currently lack. In particular, LCA practitioners would benefit if there were more knowledge and data available about the influence of certain packaging characteristics (e.g. shape, weight and type of material) on consumer behaviour.

Abstract [en]

Packaging saves food by protecting the content from physical and chemical degradation during the distribution and storage processes. However, packaging can do much more than that. This article explores how the design of a package may help, or indeed hinder, the consumer to avoid wasting food. A number of packaging attributes influence consumer behavior. The influence is different depending on the product‘s characteristics and the needs of the consumer. For many products, it might be better to add packaging material, for example, by creating smaller sizes of the product to reduce food waste and the overall environmental impact.

Abstract [en]

Packaging has great potential to contribute to sustainable development through its functions. Previous research has indicated a need for increased knowledge among consumers, suppliers, authorities and media of how packaging functions and features influence sustainable development. Previous research also shows the need for a common terminology of packaging functions and features in order to facilitate and improve communication and understanding in development and decision processes. This conceptual paper sets out to identify, collect, analyse and systemize packaging functions and features and evaluate them based on their indirect contributions to sustainable development. The systemized functions and features are expressed in generic terminology. Three clusters of packaging functions were identified from the literature: protect, facilitate handling and communicate. Nineteen packaging features were also identified. They were grouped under the three functions and elaborated based on their indirect contributions to the environmental, social and economic dimensions of sustainable development. Fourteen potential positive indirect effects were identified including decreased product waste, reduced risk for human health hazards, increased handling and transport efficiency. Decreased product waste was generated by 13 of the features and was thus the most frequently appearing. Reducing waste is thereby indicated to be a manifold matter, but also one of great potential. The proposed terminology can contribute to an increased understanding of how packaging can actually contribute to sustainable development. In a theoretical context, this paper attempts to complement earlier work in sustainable packaging development by its emphasis on the indirect contributions of packaging to sustainable development.

Abstract [en]

Increasing population and environmental changes poses a significant pressure on the global food supply chain. With the large quantities of food waste that’s been reported over the past couple of years packaging can play a more significant role in reducing the food wastage. Together with actors along the entire value chain we are developing new innovative packaging solutions to reduce food waste throughout the value chain, from food producers to consumers. The purpose of the study is to design and optimize new packaging system solutions so that no part of the chain is optimized at the expense of any other part. In the fall of 2015 the food wastage was examined in three supply chains, salsa in glass jar (A), rice pudding in plastic packaging (B) and lettuce in plastic packaging (C), by using waste audits in the businesses, collecting, comparing and analyzing data. For consumer insights ethnographic studies was used in ten Swedish households. Interviews have also been conducted with consumers in retail stores. The supply chain study indicates little wastage for A and B and higher for C. Consumer report some handling difficulties with the food packaging and reasons why food is wasted. The main reasons being that the food gets bad, difficulties to empty the packaging and that the amount of food is higher than their needs. A majority of the consumer state that they often view packaging as something unnecessary. Consumers do not give packaging functions many thoughts in general and many have difficulties in judging the packaging functions.

Abstract [en]

The United Nations Food and Agricultural Organisation (FAO) have estimated that 1.3 billion tonnes of food is wasted across the supply chain, while food security emerges as one of the leading challenges facing a growing global population. Life cycle assessment (LCA) can illustrate the environmental implications of food production, consumption and waste. In 2005, Peter Menzel and Faith D’Aluisio presented a photographic study in “Hungry Planet – What the World Eats” documenting what thirty families across twenty-four countries ate during the course of one week. The weekly food purchasing inventories of three of these families have been combined with LCA data to report the greenhouse gas intensity of these food purchases. The greenhouse gas emission profile including those of 128 varieties of fresh food, along with data on packaging material production and household food waste, have been used in the calculations. The paper will present the findings illustrating the contribution each component has: food, packaging and food waste; and will also discuss the implications for food packaging design.

Abstract [en]

The role of packaging systems to reduce food waste is rarely modelled in life cycle assessment (LCA) studies. This means that a packaging system format with a lower environmental impact that causes high food waste, may appear to be a better alternative than a packaging system with a higher environmental impact that reduces food waste. This can be contradictory to the purpose of using LCA to reduce overall environmental impacts, because food generally has a higher environmental impact than the packaging system. This paper highlights packaging attributes that may influence food waste, and demonstrates via six packaging scenarios how the environmental impact for the functional unit of “eaten food” can be calculated when food waste is included. The results show that the function of “avoiding food waste” is a critical packaging issue. The connection between packaging design and food waste should be acknowledged and valued by relevant stakeholders such as: food producers, manufacturers, brand owners, retailers and consumers, and also in packaging regulations. To fully explore the potential for packaging systems to reduce their overall environmental impact, food waste should be included.

Abstract [en]

The amount of food waste needs to be reduced in order to sustain the world's limited resources and secure enough food to all humans. Packaging plays an important role in reducing food waste. The knowledge about how packaging affects food waste in households, however, is scarce. This exploratory study examines reasons for food waste in household and especially how and to what extent packaging influences the amount of food waste. Sixty-one families measured their amount of food waste during seven days and noted in a diary why each item was wasted. Thirty of the families had participated earlier in an environmental project including education in environmental issues of everyday life. About 20-25% of the households' food waste could be related to packaging. Three packaging aspects dominate the packaging related waste: packages that the consumer noted as being too big and packages that were difficult to empty, and wastage because of passed "best before date". The environmentally educated households wasted less, especially of prepared food. They also wasted less food due to passed "best before date". These households were more observant to packaging aspects in relation to food waste. The observations made could be used to learn more about packaging attributes that affect food waste. Although they recognised packaging influence on food waste, these households expressed lower satisfaction with packaging functions and wanted packaging to a lower extent. (C) 2011 Elsevier Ltd.
