Urban circular economy initiatives: Development and application of a unified theoretical framework

Existing assessments of Urban Circular Economy (UCE) initiatives often fail to address the multidimensional nature of urban circularity, particularly regarding social inclusion and stakeholder engagement. To address these limitations this research develops a unified theoretical framework by integrating three existing frameworks, the 9 DB framework (for identifying the development stage of waste and resource management), the 10R ladder (for defining the depth of adopted circular strategies), and the inclusive circular city (ICC) framework (for assessing environmental, social, economic and spatial dimensions, including participatory engagement). The unified framework is applied to the network of Circular Craft Centres (CCCs) in the Netherlands, a bottom-up initiative launched in 2019. The application of the framework reveals that the CCC network promotes the long-term circulation of materials, including textiles, furniture, electronics and plastics, through multi-stakeholder collaboration involving governments, organizations, businesses, citizens and vulnerable groups, with a focus on labour market integration. It also shows that CCCs have the potential to foster sustainability, circularity, and inclusion while underscoring the importance of place-based policies, the diversity of circular strategies implemented, and the active involvement of stakeholders across ICC dimensions. This study contributes to the development of holistic theoretical frameworks for evaluating UCE initiatives and supporting inclusive urban circular transitions. © 2025 The Authors
