- Abstract (Swedish)
- The construction sector is responsible for around 40 % of all generated waste in Sweden and is also responsible for around 21-22 % of all carbon emissions. In a sector that is responsible for a substantial part of Sweden’s climate footprint, it’s important to find solutions to the negative effects towards the climate. Much of the generated waste comes from building and demolition waste which ends up in landfills. The emissions that the building sector generates are often a result of combustion in relation to production of new materials or energy recovery from old materials. The reuse of bricks lessens the need for further material creation as well as limits waste generation by keeping brick products in the material cycle longer.

The reuse of bricks lessens the need for further material creation as well as limits waste generation by keeping brick products in the material cycle longer.
The purpose of this study is to study demolition-bricks potential for reuse based on when the bricks entered the building stock. The study is limited to a analysis of the bigger municipalities in Scania, in the south of Sweden.
The study was performed through grading brick building that were demolished or were soon to be demolished in the four biggest municipalities in Scania. The grading was made based on potential for reuse, and later analysed in the pursuit of finding connections between building year and potential for reuse. The study also consisted of two interviews. One interview was conducted with two construction engineers from a building-consulting company and the second interview was conducted with a representative from a company which focuses on reuseable brick products. The interviews were conducted for background information and perspective in the research area.
The results showed an overarching trend of lowering potential for reuse the later the bricks building year was. The old bricks, specifically bricks from the 1910-1940s possessed the best technical qualities and were the most appropriate for the recycling process. The demolition-bricks from the 1950-1970s possessed worse technical characteristics but proved to have a high potential for reuse through having large quantities of demolition-bricks available despite the associated risks. The study’s overall results were that most brick in the Swedish building sector is in fact appropriate for reuse provided modern technology, although the nuances that come with brick-reuse should never be considered negligible.
