WHAT IS CIRCUIT?

This is an image of one of the CIRCuIT logos, which is a square of four shapes: on the top left a circle, on the top right a square, on the bottom left a square, on the bottom right a square with a rounded corner on the bottom right.

Circular Construction in Regenerative Cities (CIRCuIT) was a collaborative project running from 2019-2023 and involving 31 ambitious partners across the built environment chain in Copenhagen, Hamburg, the Helsinki Region and Greater London.

 

Funded by the European Commission’s Horizon 2020 programme, the project supported the creation of regenerative cities by implementing sustainable and circular construction practices.​ 

OUR OBJECTIVES

Many techniques, tools and approaches related to circular construction have been developed and tested around Europe, but circular techniques are yet to be demonstrated effectively at a city or regional level.  

 

CIRCuIT aimed to bridge the gap between theory, practice and policy by delivering a series of demonstrations, case studies, events and other dissemination activities that showcase how circular construction approaches can be scaled and replicated across Europe to enable cities to build more sustainably and transition to a circular built environment.  

​

Our objective was to demonstrate how cities can scale and replicate these activities and transition their construction sector to a circular economy.

Reduce carbon emissions and increase regenerative capacity in the four cities

This graphic is a 3D outline of bricks stacked on to of one another. 3 bricks on the bottom, 2 in the middle, 1 on top.

Reduce yearly consumption of virgin materials by 20% in new built environments

Demonstrate cost savings of 15%

OUR ACTIVITIES

Each city delivered nine demonstrations exploring three innovative interventions:

  • Urban mining and reverse cycles - the reuse and recycling of materials

  • Extending building life through transformation and refurbishment

  • Designing for disassembly and flexible construction to make reuse, recycling, transformation and refurbishment easier

The project set up knowledge and skills sharing to support cities in implementing circular construction solutions and initiate changes at system level through:

  • Developed recommendations, tools and resources, including urban planning instruments, public procurement criteria and roadmaps

  • Established a Circularity Hub - a suite of digital platforms including a data atlas, dashboard, citizen engagement portal, materials exchange platform and wiki

  • A knowledge sharing structure to disseminate project experience, knowledge and practices to cities and the construction industry which will include providing training and establishing networks across Europe.

CIRCuIT provided a consistent and comprehensive approach to data collection, analysis and management including: 

  • Developing a concise and robust list of indicators to provide an overview of circularity at city level

  • Creating a material stocks and flow database
