Exploring Dynamics in Construction Circular Supply Chains Using a Systematic Literature Review: New Supply-push and Demand-pull Perspectives

A full transition to Circular Economy (CE) in construction requires a rethinking of its operations from a supply chain viewpoint. The transition to Circular Construction Supply Chains (CCSC) can be discussed from supply-push (SP) and demand-pull (DP) perspectives; however, this understanding is underdeveloped in the literature. The study aims to explore barriers to the transition to CCSC and associated SD/DP countermeasures and investigates whether the current configuration of CCSC is SP- or DP-driven. A systematic review of 81 peer-reviewed articles was conducted. Thirty-seven barriers were identified, combined into nine factors, and further classified into three groups: technical, managerial, and contextual. Countermeasures to these barriers were linked to SP/DP and their level of control (macro, meso, and micro). Findings revealed countermeasures are mainly SP-related and used to create a DP environment. This new "push-to-pull" attribute shows the dynamic nature of CCSC transition that requires greater collaboration of actors at different levels.
