Design Thinking Tools To Catalyse Sustainable Circular Innovation

Design thinking is an innovation approach for organisations aiming to solve complex and open-ended problems, including those arising in the transition from a linear to a circular economic system. Although the importance has been recognised in business and academia, to date, insight is lacking on how design thinking can be applied within circular innovation specifically. We investigate the following research question: How can design thinking tools catalyse sustainable circular innovation? Based on the literature, we first create a framework that characterises design thinking principles, criteria and phases that could support circular innovation. The design thinking phases are ideate and design, implement and test, and evaluate and improve. The criteria include desirability, feasibility, viability and sustainability, and circularity. Finally, we identify the following principles that make design thinking suitable to tackle complex circular innovation challenges: human-centred, future-oriented, holistic, co-creative, and experimental. Consequently, against this framework, we map 11 tools that are suitable to catalyse circular innovation theory into practice through design thinking. Finally, we reflect on the future of research and practice around this subject.
