Green construction supply chain: Reviewingadvancements, obstacles, and possibilities

The fragmented supply chain in the construction sector leads to diminished productivity, resource waste, and elevated carbon emissions. This issue is exacerbated by insufficient knowledge sharing among stakeholders and project complexity. The increasing academic focus on construction management and sustainability advocates the integration of circular economy principles throughout the supply chain lifecycle. There is significant potential to enhance the understanding of decarbonization by pinpointing actionable advancements that assist stakeholders in adopting circularity principles. In this study, Bibliometrics and Grounded Theory Methodology (BIBGT) was used to combine the bibliometric tools with Grounded Theory Methodology (GTM). This review method demonstrates how AI analytics, BIM, IoT, and other technologies, when integrated with blockchain traceability, can address challenges and support sustainable practices in the green construction supply chain based on the previously published articles. Government bodies, policymakers, private firms, technology developers, and sustainability scholars can utilize the findings of this study to inform regulations, guide investments in start-ups, and foster low-carbon innovation. To build on these findings, this review systematically consolidates themes and challenges related to construction circularity using a bibliometrics grounded theory methodology that clarifies keywords, publications, concepts, technologies, and methods pertinent to construction supply chain integration while addressing current research limitations. Furthermore, this study examined the application of technology across the six lifecycle stages of construction supply chains, from planning to recycling. This review aims to bridge the knowledge-sharing gap by connecting industry and academia perspectives. Ultimately, this review identifies the primary challenges facing construction supply chains as sustainability, collaboration, adaptability, and data-sharing efficacy. The successful implementation of potential technologies and possibilities has been synthesized into a conceptual framework for future circularity research in construction, ultimately aiding in the reduction of carbon emissions in the supply chain.
