The construction sector has countless adverse effects on the environment. With the recent concerns on sustainability, methods to make construction more sustainable have become a topic of interest. The circular economy was popularized as a concept to mitigate natural resource use, slow the use of materials, and close the cycle of waste materials. The construction sector holds the most immense potential in transitioning to a circular economy. Türkiye, as a developing country, urbanizes at a high velocity. Therefore, integrating sustainable practices through transitioning to a circular economy in the Turkish construction sector is urgent. However, no specific guideline for this transition exists in Türkiye. Therefore, this study aims to propose a framework for transitioning to circularity in Turkish construction supply chains and to present the existing state of circularity in the construction sector in Türkiye. Following this aim, a literature review was conducted on sustainability, supply chains, construction supply chains, and circular economy. Through the circular strategies and methods in the literature review, a framework was proposed for transitioning to a circular economy in Turkish construction supply chains. This framework was used to prepare a questionnaire that was distributed among Turkish construction firms. The questionnaire results were analyzed and evaluated, and statistical tests were conducted. The results found that while the type of staff and their level of education do not affect the circular methods used in the construction supply chain, awareness about circularity, use of circular strategies, and digital technologies directly affect the use of circular methods.
