The concept of circular economy (CE) is high on the agenda of many planning agencies in European countries. It has also become a prominent issue in European academic education institutions. It is expected that spatial planning and design can support and add the spatial quality dimension of such a transition towards CE. However, incorporating the concept of CE in an integrative manner in urban design and planning courses is challenging because of its metabolic and complex nature. This article presents the first results of integrating design-teaching activities at a faculty of architecture with an H2020-financed research project. The integration of research and design education provided the students with a situated and indeed transdisciplinary learning environment. Students understood that they needed to address challenges from a systemic perspective rather early in the design process, meaning to understand what the relations between different subsystems and their spatial structures are. Furthermore, the experiment provided evidence that the eco-innovative solutions developed by the students are seen as an effective option to achieve objectives for a transition towards CE by stakeholders.

Nowadays, the circularity concept dominates the debate on resource management in cities and territories. The idea is often used as a vehicle towards a more sustainable socio-ecological transition, based on the circular economy (CE) framework. Unlike other sustainability frameworks, CE originates in ecological and environmental economics and industrial ecology. It focuses on developing an alternative economic and technological model for production and consumption, avoiding natural resource depletion and redesigning processes and cycles of materials (closed-loops). However, when CE is translated to cities and territories, its environmental, economic and design agency is often neglected. On the one hand, it demands to acknowledge the need for a relational understanding of space, place and actors involved and, on the other, to explore the spatial specificity of CE. Therefore, there is a need for a broader theoretical discourse on the CE’s territoriality as the predominant. Research on circular urban and territorial development demands more than merely upscaling industrial ecosystems diagrams and generating circular businesses. Consequently, what is the role of territory in the CE conceptualisation in the urbanism literature? How to interpret territories through the lens of circularity, which tools, methods are needed? Therefore, territory, its role and meaning in the CE contribution to urban regeneration is the key focus of this text.
