Abstract [en]

Due to population growth, urbanization, higher income levels, and intensive use of packaging products, the amount of waste generated by households, including food packaging waste, has been increasing continuously worldwide, posing a massive threat to societies and the environment. Therefore, proper waste management has become a challenging environmental issue and priority for governments. Along with the advances in technical aspects, such as material recovery technologies, more pressure has been placed on the strategies to move from disposal to waste prevention and recycling. Considerable efforts are being made to limit the overall production and the negative impact of waste on the environment and human health, as well as minimize the cost of waste management. Separation of different waste fractions at the source (i.e., source separation) is an integral part of such efforts toward enhancing the homogeneity of collected waste and improving the quality of materials for recycling. Sorting waste as a regular activity can also serve as a practice for improving residents' sorting behavior. However, the benefits of source separation cannot be gained without actively participating in the sorting process, which depends on the perception of convenience and the easy-to-implement nature of the process. Therefore, the design of food packaging has become an interesting concept for research and has received a lot of attention as a means to influence the consumers' sorting behavior. This is because in some way, consumer behavior is shaped by products as much as products are shaped by consumer behavior. Considering the unique characteristics of food packaging, it is expected that different food packages tend to influence a consumer in different ways. Hence, applying proper design strategies requires an in-depth understanding of packaging-consumer interactions throughout the sorting process. However, the research in this field, except for a few, is too general and usually associated with the impractical experiences around packaging material and functions. Instead, a design-oriented approach should be considered, in addition to practical experience. This thesis, therefore, aims to unfold the packaging design potential to support sorting behavior. Furthermore, how is it possible to maintain and empower the user-packaging interaction by applying different design strategies? In this case, the potential of design approaches, namely the user-centered design (UCD), design for sustainable behavior (DfSB), and design affordance, have been discussed. Moreover, the advantages and opportunities of these methods to improve packaging design, thus influencing sorting behavior, are investigated using different research methodologies.

Abstract [en]

Household waste sorting at the source is an essential part of the waste management system in many countries. Correct sorting of this waste, including food packaging waste, is cost-effective, it facilitates the recycling process and enhances the quality of the recycled product. Although there is a growing body of research that studies the effect of different attributes of food packaging on household recycling behavior, the effect of these attributes on the sorting of the food packaging waste is not well known. This contribution reviews work that studies the relationship between attributes of food packaging and consumer sorting behavior. The review highlights the potential of the visual attributes and the quality of packaging as a communication channel for encouraging consumers to sort the food packaging waste. The efficiency of the waste management system and the quality of recycled products can hence be affected by the proper design of food packaging.

Abstract [en]

Food packaging waste is a valuable resource for material recovery, if it is properly separated and sorted by consumers. The packaging itself may have the potential to assist consumer sorting by, for example, communicating a correct sorting practice. This is partly due to the fact that the sorting of packaging waste, which is a habitual behavior of consumers, can be perceived as being confusing and inconvenient. Consumers can, therefore, choose not to sort. It is argued that material recovery could be enhanced if packaging can afford easy and proper sorting and separation. To investigate the potential of packaging to support proper sorting, six types of yogurt and cream packaging were examined across 15 households in Karlskrona (a medium-sized Swedish city). The aim is to investigate the effect of selected packaging attributes on consumer decisions regarding waste sorting. The results reveal that some of the selected packaging waste is not properly separated and sorted. It is concluded that the design of food packaging based on user-centered needs could affect consumer decisions for the proper sorting of packaging waste, which enables improved material recovery. The design should focus especially on the package’s visual attributes, the material selection, and the package´s waste sorting related functions

3. Design affordance of plastic food packaging for consumer sorting behavior

Abstract [en]

This research aims to understand why consumers miss-sort plastic food packaging and to what extent the design affordance of packaging can influence consumer sorting behavior. A photo-based observation study and semi-structured interviews were used to gain a deeper understanding of the miss-sorting behavior and how it could be affected by design affordance. This explorative study suggested that the packaging form, size, durability, haptic aspects, and visual communicative properties influence how consumers perceive the value of packaging. This is important, because packaging with low attributed values are not considered worth recycling or correctly sorted and are more likely to be miss-sorted. Hence, a well-afforded food packaging design is expected to improve how consumers perceive the value of packaging and to consequently improve sorting behavior.
