Project: Circular Trust Building – CTB
The long-term goal of the Circular Trust Building (CTB) project is to facilitate the transition from the now dominant linear value chain to a circular economy in the construction sector. Through collaboration and joint learning between 15 public and private partners from six countries in the North Sea region, CTB will demonstrate the conditions for the transition in seven different pilot projects. Linnaeus University will together with GodaHus (www.godahus.se) carry out a series of knowledge-raising measures in circular construction and together with Vöfab and Region Kronoberg will apply circular building knowledge in two pilot projects in the county.

More about the project
There are several things that make it difficult to change to circular construction; the lack of information about the type and quantity of refurbished material that can be reused/recycled, lack of information about the quality of reusable material, logistics, knowledge of the correct way to dismantle, transport and store, negative attitude, lack of interest and demand for circularity among customers and lack of contractual forms.
In Kronoberg county, there are examples in the construction and real estate industry where they have collected demolition building materials for reuse and also used recycled materials for construction. But there are too few and too small projects that are carried out for it to be done in an efficient and simple way. Carrying out circularity projects on a larger scale requires new solutions, joint strategies and action plans as well as an increase in the skills of everyone involved.
The transition to a more circular economy and a circular and resource-efficient construction sector is crucial to achieving climate neutrality by 2050. Currently, the construction industry in the EU accounts for 12% of greenhouse gas emissions and for 50% of virgin material extraction and 30% of all waste generated is construction and demolition waste. However, the transition is slow and the effect of the use of circular building materials is still low.
Circular Trust Building (CTB) will facilitate this transition to a circular building sector by providing a platform for knowledge transfer across multiple sectors and creating consensus among actors in the entire value chain in the North Sea region.
In seven pilot projects around the North Sea region, it will be demonstrated with local stakeholders how to achieve a 25% reduction in the material footprint from construction and renovation.
In Kronoberg, two demonstration projects with circular construction are planned that will serve as good local examples. Through an increased level of knowledge, the projects will be able to contribute to reduced climate impact, reduced amounts of waste and increased resource efficiency in the construction and property sector in Kronoberg. The results from the project will also be helpful in the longer term for developing strategies and business models that will ultimately be used by local decision-makers and companies.
The project is part of the research in the Sustainable Built Environment Research (SBER) research group and the Linnaeus Knowledge Environment Green Sustainable Development.
