Helsinki Circular Economy Cluster

The Helsinki Circular Economy Cluster Program promotes circular economy in construction by conducting pilot projects, developing tools, and providing training.

Helsinki as a Pioneer in Circular Economy for Construction

The Helsinki Circular Economy Cluster promotes circular economy innovation and business by bringing together stakeholders from the construction sector. Circular economy doesn’t happen alone – it requires courage to try new things, share expertise, and collaborate across the entire industry. That’s why experimentation, research-based knowledge, and sharing lessons learned are essential.

The cluster supports practical pilot projects and collaboration between construction actors, helping to discover new business opportunities within the circular economy. Together, we develop circular design, extend building lifecycles, enable intact deconstruction, and promote the reuse of materials and building components.

The cluster focuses especially on advancing circular economy in construction because the City of Helsinki plays a strong role as a client, developer, and builder. We invite companies of all sizes, research institutes, universities, and other organizations who want to drive circular economy forward through concrete actions. Your organization can be part of making a difference!

Join us now!

Feel free to get in touch and become part of the circular economy pioneer network. Several construction companies have already committed to promoting circular economy through concrete actions. Together, we are building a more sustainable future — while also discovering new opportunities to grow and succeed.
