This indicates a need to transition towards sustainable reuse routines. In this study, we investigate to what extent reusable products are already established in society and what design properties users require. We compare the results between user clusters and countries. To create a meaningful list of reusable products to investigate, we distinguish four categories based on typical barriers by means of focus groups (n=3) and interviews (n=32). Next, we did a survey (n=3000) in three countries (Belgium, Russia, U.S.) to define user clusters and investigate product usage and design requirements. Most established products are hard-material products such as lunch boxes, while intimate hygiene products, such as menstrual cups, are not established yet. Multifunctionality and compactness are the most indicated product requirements. There are significant differences between countries and clu...

In order to understand how designers can rethink this always negative balance and outcome of waste creation, research was done to understand packaging and preservation of PVFs from both a technological and consumer perspective. A mixed research approach was applied, including literature study, expert interviews, packaging analyses, consumer survey and photo study. In sum, we concluded that the main function of packaging is preservation, including both protection from outside influences and conservation in best possible conditions. Optimal preservation should consider each PVF's respiration and transpiration needs, and ethylene sensitivity. Consumers are mostly not aware of correct preservation methods. However, on the other hand, their awareness evokes an important tendency to ban plastics without considering their positive im...

Reusable labware has the potential to reduce this waste significantly, but the design of such products must take into account quality assurance to guarantee the accuracy of experiments. Insights were gathered through the generation of an overview of the available techniques for verifying labware after use and decontamination. As during different design cycles verification of prototypes is needed, these techniques were evaluated and translated to be applicable in the specific context of a design lab. Therefore, this study presents a protocol which can be used as a verification tool while designing safe, reusable labware for chemical laboratories. This protocol consists of four different steps: (i) visual inspection, (ii) mass & size comparison, (iii) leak test, and (iv) chemical stability test.

In addition, design inquiry, as a process of thought and planning, is also a constructive process. This provokes the question of how to construct controversies from a designerly perspective in order to steer higher-order learning. This paper presents a theoretical contribution to the field of social system design by providing the first insights into design intervention to facilitate a network of allied construction. Through a systematic review of the concept of conflict and disagreement, the link between controversies and knowledge transmission is examined in order to highlight the benefit of controversies in a constructive way. Next to that, the essential steps for constructing a network of allies are proposed. These steps are compared with specific aspects of design in order to unfold the advantages of design for network construction. Fin...
