The construction sector is responsible for 32% consumption of natural resources, causing 850 million tons of construction waste in EU and a major economic player providing about 9% of the EU’s GDP. This happens since the construction industry mostly have applied a linear economy model throughout decades with the concept “Take, make, dispose of” where resources are used once and then disposed. As a counterresponse, Circular Economy (CE) was introduced with aim of keeping materials within a closed loop and regain its value in the End-of-Life phase. This paper aims to investigate how CE is used in the construction sector together with its manufacture supplier and how their existing collaboration works in a CE concept. The 11Rs framework has been used as a reference within the concept of CE through a systematic literature review, where 117 articles have been reviewed. Due to technical development within the sectors information connected to products and materials have been examined to identify existing barriers regarding management and exchange between stakeholders. Additionally, six interviews have been carried out with aim of receiving the industries point of view and thereby specify potential research gap regarding CE. The study resulted in numerous key findings of how CE is used in the industry today and identified research gaps. According to the study, existing research are not yet fully explored for companies to apply CE methods and requires further research. Also, there is an existing organizational lack of knowledge of CE and its benefits as well as poor collaboration between cross-sectional stakeholders both with information exchange and processes.
