This thesis explores the challenges and opportunities of reusing construction and demolition waste within Sweden's construction sector, employing a PEST-SWOT analytical framework. The focus is on three primary materials prevalent in residential single-family houses: brick, concrete, and timber. The study identifies key political, economic, social, and technological factors that influence material reuse practices. The analysis highlights substantial barriers including regulatory complexities, lack of incentives, and the tendency to often prioritize new over reused materials due to perceived risks and higher costs associated with reuse. Despite these challenges, the research identifies significant opportunities for advancing material reuse. These include the potential for implementation of technological advancements in material processing, and growing public and governmental support for sustainable construction practices. The thesis goes forward by proposing strategic recommendations aimed at enhancing the adoption of reuse practices, thereby contributing to a more sustainable and resource-efficient construction sector in Sweden. / Demand trust for circular building materials
