Purpose: This study aims to study the management of demolition waste in construction production in a major renovation project while proposing different improvement possibilities. Method: In this study the chosen method was literature study and a case study that was compared to a reference object. Furthermore, in the case study an interview was arranged with the site manager and a survey was conducted with a portion of the workers that were involved in this project. Results: The results show how NCC is intended to work efficiently and calculatedly when preparing a project. Furthermore, the results show the factors that have affected the project both directly and indirectly. In addition, some suggestions for improvement to achieve a smaller amount of waste are proposed. Conclusions: The conclusion is that NCC follows their guidelines for how to achieve sustainable demolition. In this project, they came in late, which meant that they did not fully succeed in planning well for the project. However, regarding the spontaneous measures that needed to be carried out, they received an acceptable amount of waste.
