Abstract
Circular economy is an important part of achieving a sustainable planet. This paradigm shift is also crucial for the construction industry to embrace. By introducing and establishing a marketplace for reuse of construction products, the industry takes a stride towards sustainability.The purpose of this thesis is to enhance sustainability within the construction sector. Further the thesis’ goal is to identify viable opportunities for material reuse while uncovering the barriers for reuse. This will be achieved by addressing the research question:«Which products requires low effort for reuse, and what are the barriers for reuse, perceived by the construction industry?»This thesis has been conducted through interview and literature review. The interviews provided valuable insights into identifying products that needs low effort for reuse. In addition, it has contributed to conclude on which products are desirable for reuse, as well as highlight the barriers associated with reuse. Moreover, the interviews supplied data to calculate costs and greenhouse gas emissions linked with the construction of commercial buildings.Analysis reveals that products such as: system walls, glass walls, ventilation ducts, washbasins, water closets, gypsum, doors, cable trays and ceiling tiles used as sound insulation in walls, are perceived as products that needs low effort for reuse. The results demonstrates that reuse of these products often entails lower costs compared to purchasing new ones. Reusing these products also tends to result in reduced greenhouse gas emissions. In addition to this, the industry identifies challenges such as costs, logistics and accessibility as significant barriers for reuse.
