In this study, a methodological approach, mainly based on expert interviews, was proposed to gain in-depth insight into critical success factors for circular business model innovation. As a result, a framework covering critical success factors for circular business model innovation is developed, comprising nine top-codes and 37 sub-codes, and an analysis of each factor’s contribution to the UN’s Sustainable Development Goals was performed. The study thereby extends the theoretical basis for further research on circular business model innovation, as well as identifies their practical implications.
