As part of the CityLoops project, the Danish cities Roskilde and Høje-Taastrup are piloting a series of demonstration actions to close the loop in Construction and Demolition Waste (CDW). In two YouTube videos they provide an overview of some of the most important activities they have undertaken so far.

In Roskilde, the Musicon district, a 200,000 m2 former concrete factory and gravel pit,is the main demonstration sites. Here, existing buildings are being refurbished or demolished and structures, construction materials and soil are being used in new constructions, with the aim to create a new neighborhood. Roskilde’s video provides a virtual tour around the activities carried out at Musicon, explaining how the experiences gained have helped the implementation of circular principles in the construction strategies of the municipality.

In Høje-Taastrup the focus is both on including circular practices in public construction projects, as well as on influencing construction and demolition projects for buildings and sites not directly owned by the municipality. Its video showcases how the Municipality turns demolished concrete into aggregate and uses it as a foundation for its new city hall. This will be Denmark’s largest public building with a recycled foundation.
