Workshop 2, Circle Scan. Material flow analysis and circular possibilities

On Wednesday 4 March, we were finally to see the results of phase 2 of the Circle Scan project. Based on feedback along the way, the consultants have from Circle Economy spent a lot of time collecting data from, among others, Eurostat, Statistics Norway and its own databases. There were several of us who were excited to see the material flow analysis in the form of so-called. Sankey diagram.

A project with many stakeholders

The final commentator for the workshop was, as last, Jordi Pascual. He brought with him Noah Baars and Sofie Pindsle Circular Norway. It was otherwise especially nice to have the mayors Lise Selnes and Knut Hvithammer. Political commitment is very important in transforming the results of the analysis into political tools - simply making the circular economy an important green engine of transformation in our region.

We were also this time also lucky to have external guests; Kia Klavenes from Pure (which is now part of KPMG) and Marianne Haugland from KS Bedrift are important for inspiration and knowledge sharing, and can share experiences further in their own organizations and circles. Otherwise, we were gathered from the administration in six municipalities, GIR (renovation), Klosser Innovation and Høgskolen Innlandet, as well as Topos Arkitektur from the prototype project.

Material flow analysis - private homes generate the most waste and emissions

A large part of the work since the previous workshop had been used to collect data and visualize material flow. The figures are based on basic data from regional companies, public literature and studies, national statistics (SSB) and EXIObase (Circle Economy's own database) and Eurostat registers classified by NACE sectors (industry).

The materials are divided into the following categories:

  • Biomass: Includes different types of wood used in the form of construction such as timber, lumber, etc.
  • Minerals and chemicals: Includes solid materials that are present in nature, such as clay, sand, stone, aggregate, limestone, granules etc. used for building construction.
  • Metal: Includes raw and processed metals and iron and steel products used in the construction of buildings in the region.
  • Water: Includes the amount consumed in a given year for the different construction phases (construction, use, demolition).
  • Energy: Includes energy in various forms, from fuel to heat energy and electricity. Emission flows include greenhouse gas emissions, the majority of which consist of CO2.

The material flows are again divided into private homes, purpose-built buildings and infrastructure. The figures are based on figures from 2018, which was a quiet year in the construction and construction industry in the region, with 128 buildings.

Private housing is mostly in the form of waste and emissions.

Clear change in building stock in a 100-year perspective

Furthermore, an analysis was made of the distribution and concentration of different types of building mass according to the typology of our homes and purpose-built buildings. This was combined with population projections and the need for new housing in the coming years.

There are clearly both challenges and opportunities associated with the composition. Circle Economy pointed out, among other things, that minerals from the 50s onwards are difficult to reuse / recycle.

To look at the picture of possibilities, we were presented with different projection scenarios and different demolition scenarios. Based on the building's typology, there will potentially be access to different types of released secondary material.

A challenge, but also an opportunity, is to match access to secondary raw materials with the need for materials for new buildings.

7 possible strategic directions identified

After lunch we continued working on strategic directions. Circle Economy had identified seven different strategic choices, which we were to prioritize down to three specific strategies. Although this was a difficult process, we believe we have concluded. Project returns with specific recommendations.

Now the business community must join

In phases 3 and 4, there is a close dialogue with the players in the construction industry in the region.

We will return in detail about how we think this will take place, and already on March 17 in the meeting of the Sustainability Network at Maarud, there will be an opportunity to hear a little more about how business actors can be involved in the project.

Circular housing prototype along the way

As some people know, the Regional Council in the Kongsvinger region is in the process of building one prototype of a circular dwelling, targeted youth.

The construction project is a collaboration with Skarnes Videregående, building and construction technology, Topos Arkitektur and GIR (our inter-municipal waste company). A prerequisite for the building is that at least 50% of all building materials are based on recycled or recycled materials.

Feel free to contact us if you want to contribute to realizing the prototype, or want to hear more about how the business community can connect to further work in Circle Scan - Kongsvinger Region.
