As circular economy (CE) becomes an increasingly important framework for combating climate change, its applicability in the construction sector still faces significant challenges.

An international research study, conducted with a team that includes Assoc. Prof. Dr. Ömer Ekmekçioğlu from Istanbul Technical University, has identified critical success factors (CSFs) to accelerate the transition of the construction sector to a circular economy, developing a comprehensive implementation framework.

The study examined the ReSOLVE framework (Regenerate, Share, Optimize, Loop, Virtualize, Exchange) within the construction sector by analyzing survey data from construction professionals in Kazakhstan, Malaysia, and Turkey. Using Fuzzy Analytical Hierarchy Process (F-AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), researchers identified the most crucial CSFs. The results revealed that Optimize and Loop (Recycling) were the most significant components for ensuring a successful circular transition in the construction sector.

The study groups 27 critical success factors into seven key action areas, providing a comprehensive roadmap for industry stakeholders: legislation and documentation, financial support, design, external stakeholders, technological advancements, internal dynamics, and construction/production/waste management. Researchers highlight that this framework will serve as a guide for policymakers and industry professionals, facilitating the widespread adoption of circular economy principles.

Future studies will focus on enhancing algorithmic efficiency, integrating more environmental variables, and developing systems compatible with virtual construction technologies. By promoting the adoption of circular economy principles, this scientific framework paves the way for a greener, more efficient, and economically sustainable construction industry.
