The United Nations aims to achieve net-zero carbon emissions by 2050, while Sweden has seta target to reach net-zero emissions in the construction industry by 2045. In 2020, constructionaccounted for approximately 21% of Sweden's domestic CO2 emissions. To meet these goals, a roadmap has been developed, targeting net-zero emissions by 2045. Skolfastigheter AB, among others, are compelled to take action to reduce greenhouse gas emissions and one wayto align with the climate objectives is to promote reuse. However, the company currently lacksan established approach for reuse. This report focuses on reducing the environmental impact of renovation projects within Skolfastigheter AB through reuse. The objective is to identify reuse prerequisites and developstrategies for promoting reuse in renovation projects. The theoretical background covers the circular economy, waste hierarchy, material reusepotential, requirements, specifications, sales, and BIM in relation to reuse. Two schools under Skolfastigheter AB:s management are observed, and interviews are conducted with nine actors in the construction industry. The results reveal a similar material structure in the observed schools. Furthermore, it reveals challenges such a lack of documentation of materials, reoccurring vandalism and that reuse has been absent withing the management. The interviews provide nine categories to promote reuse in renovation projects: a systematic working model, inventory, quality, BIM tools, competence, design choices, hazardous substances, collaboration, and EPDs. Conclusions highlight the prioritization of installations and porcelain for reuse, emphasizing the importance of the working model, inventory, and quality as key factors for promoting reuse.
