Digital information management to increase the reuse of building materials

The construction industry contributes significantly to global greenhouse gas emissions and extraction of primary resources. The linear economy models used in building development projects are unsustainable. Hence, implementing circular economy models in the building development process is necessary. This paper aims to increase reuse in building projects. The study utilized a literature study, 18 interviews with construction industry professionals, and two case studies. The focus of the study was the role of digital information management in achieving a circular economy and a narrowed scope on the reuse of building materials and components. The results show six challenges for increasing the reuse of building materials in construction projects. The most central challenges are profitability, human willingness to action and change, and storage of reusable building materials. Based on the findings in this paper, a framework is developed for how digital information of construction resources can be utilized and managed throughout the lifetime of buildings. The suggested solutions will enhance the ability of property owners and developers to achieve circularity in their building projects and existing building stocks. In this respect, this paper contributes to the emergence of new profitable business models and markets within a circular value chain for building materials in the construction industry.
