Möjligheter och utmaningar kring återbruk i nyproduktion av byggander

​This bachelor thesis in construction engineering at the Department of Engineering Sciences, Uppsala University is produced in collaboration with NCC Uppsala with the purpose to give insight about NCC:s current reusage methods of construction materials, and if they could be improved. The greenhouse effect correlates with the overconsumption of our earth's resources, which is taking place in today's modern society. Reports say that the construction industry alone yearly causes about a third of the total waste generation in Sweden, excluding mining waste. Throughout interviews with three different site managers working for NCC, their positive attitude towards increased reusage in their projects was recurrent. But the interviews did also show deficiency regarding instructions and information about the existing recycling channels. Furthermore, the interviews also showed that a lack of resources to implement efficient structures made reuse impossible to any greater extent. In order to create a perception of the potential cost-saving as a result of increased reusage, an observation with an associated cost-saving calculation has been performed. The cost-saving calculation shows a great potential in quantities of recyclable material. On the other hand, the cost savings in the form of reduced waste management fees are very small in this context. Three different development proposals about reuse are presented as the result of this thesis. Firstly, to investigate the instructions and framework for the existing channels for reuse. Secondly through established routines, include reusage as a key point in the daily work. Lastly through co-operation with external companies that are specialized in reusage in the construction industry.
