7 European cities pilot solutions to be more circular. Høje-Taastrup and Roskilde (Denmark), Mikkeli (Finland), Apeldoorn (the Netherlands), Bodø (Norway), Porto (Portugal) and Seville (Spain) are piloting a series of demonstration actions and over 30 new tools and processes across construction and demolition waste and organic waste.

They do this with the aim of achieving material circularity as part of an EU-funded CityLoops project involving 28 partners.

Rijkswaterstaat is a partner and Work Package leader on Circular Procurement developing city procurement scans and delivering expert support on circular procurement and circular construction solutions.

Towards a circular economy

Construction and demolition waste (CDW), including soil, and organic waste (OW) are 2 urban material flows with significant environmental impact and carbon footprints in all European cities. The CityLoops project will develop a series of innovative procedures, approaches and open access and open source tools to embed circularity within planning and decision-making processes for CDW and OW in cities.

The 7 pilot cities, all of them small- to medium-sized ones, will structure their pilots in 3 phases: inception and preparation phase; demonstration phase; and replication phase. The aim is to close the respective material loops and the ultimate goal is to drive the transition to a circular economy.
