Summary

Over the last decade, the concept of a circular economy, an industrial economy that is restorative or regenerative by intention and design, has gained increased attention of policy makers, industry and academics. Recently the number of innovation projects, set up by local governments, communities, non-governmental organizations and businesses, to experiment with new sustainable technologies for a circular city, has increased substantially. This paper aims to explore how in this emerging field different stakeholders collaboratively create value and develop a viable sustainable business model. We do so by building on business model literature and literature on innovation networks and combining these with insights on value outcomes and learning from strategic management. For this study we take a qualitative research approach, building on four innovation projects for a circular city, characterized by collaboration of a wide variety of stakeholders, each being initiated and coordinated by a different stakeholder type. The findings show an emphasis on technical and organizational learning, influencing expected and unexpected value outcomes. The main contribution of this paper is a conceptual framework to analyse value creation and capture within the context of open partnerships through different learning types. Learning proves to be an effective mechanism in innovation networks to create and capture more economic, environmental and social value then initially aimed for.
