Sammanfattning: A linear consumption model has long operated in several social structures, which is often referred to as the “take-make-waste” model and does not take into account the physical limit of resources. This has become a growing problem, not least in the construction sector as they use more resources and produce more waste than any other industrial sector. An alternative to the linear consumption model is the concept of circular economy, which aims to take advantage of consumed materials through recycling and reuse. A large amount of the construction and demolition waste generated is of a high quality and has the potential to be included in a circular material flow. However, a transition to a circular concept means a change in the entire industry. The aim of this study was to investigate how building and construction contractors view “circular construction”, what obstacles and opportunities exist with it. The study will also identify the areas that need to be developed in order to promote a circular economy. Using surveys and literature analyses, this study concludes that there are many barriers to the implementation of circular economy in the construction industry. The obstacles described are partly that the supply of recycled or reused material does not match the demand and that there is no marketplace for an exchange of these. Additional obstacles identified were increased costs, an absence of incentives to design products and buildings for disassembly and reuse and a lack of collaboration between actors along the entire supply chain. This paper also highlights that the areas that need to be developed is recycling or reuse of complex building materials and an increased use of alternative construction materials.
