Use - clean - repeat: Understanding user, product, and context to design for long-term reuse

Abstract

With escalating concerns about pollution and resource depletion caused by single-use products, the need to adopt reusable alternatives is widely acknowledged. This paper presents an investigation into the barriers and motivators to the long-term use of reusable products. The qualitative research consists of thirty-two semi-structured interviews with consumers, addressing the acquisition, usage, and discontinuation of the use of reusable products. From the results, we distinguished four product categories - intimate care, daily shopping, at home, and on the go - providing tailored insights into specific barriers. Next to this, we argue that willingness, ability, and routine are needed to increase the chances of successful long-term reuse. Based on these insights, we developed suggestions for designers including several design strategies and intervention points. We recommend incorporating the suggested product categories into future research, delving into persistent usage thresholds through case studies. Besides this, alternative reuse models should be further explored.
