Local recycling and reuse of concrete and soil: The societal impact of double-loop learning from circular urban transformation projects

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review


The article presents certain findings from a large European research and development project aiming to generate societal impact through multi-stakeholder collaboration based on circular economy principles in the built environment. In the project, eight apartment buildings were demolished, and recycled aggregate concrete was used to cast the foundation for a new city hall being constructed nearby. Additionally, excavated soil from the construction of the city hall was transported to the urban development site where apartment buildings had been demolished, and the excavated soil was used in the terrain for the new urban development in the area. The local reuse of excavated soil significantly reduced transport volumes as the soil would otherwise have been transported long distances out of the city. The primary impact of the project was the direct environmental effects associated with the local concrete and soil recycling. The secondary impacts were linked to improved coordination and management of circular construction projects in the municipality through knowledge and competences being developed during the project (single-loop learning). Finally, the project also created awareness in the municipal organisation about strategic and organisational changes needed to facilitate future circular construction projects (double-loop learning)
