Identification of parameters and indicators for implementing circularity in the construction industry

The increase in population, rapid urbanization, the required infrastructure development, the linear development model adopted by the construction stakeholders, and the unaccountability of construction waste have put tremendous stress on existing natural resources. The world has witnessed a situation where resource optimization through mitigation strategies has become significant for sustainable construction. A circular economy keeps the resources in the loop for the longest possible, eliminating waste from the system. This paper attempts to identify the parameters and relevant indicators for bringing circularity to the construction industry. During the research, 144 indicators were identified through a literature review which was followed by a three-round Delphi survey to attain consensus from 30 experts. Finally, after three rounds, 78 indicators were shortlisted, which received maximum consensus among the experts (W = 0.75). Construction stakeholders and decision-makers can use the identified list of indicators to bring circularity to the construction industry. © 2023, The Author(s).
