Innovative application of digital platform in construction waste supply chain management under circular economy

The construction industry generates substantial waste, and despite various policies and measures, the expected outcomes of resource recovery have not been fully realized. Digital platforms offer new opportunities to address inefficiencies in construction waste management, yet their application remains preliminary and fragmented. This paper develops an application model of digital platforms for construction waste management under the framework of the circular economy. Based on case studies, field investigations, semi-structured interviews, and expert consultations, the study formulates a strategic framework for integrating digital platforms into construction waste recycling processes. The proposed model demonstrates that digital platforms can enhance transparency, reduce transaction costs, and improve resource utilization efficiency by enabling rapid matching of supply and demand information. Furthermore, the aggregation of data across the construction waste life cycle provides a basis for optimizing platform functions, attracting stakeholders, and supporting government monitoring and regulation. This research establishes a new paradigm for construction waste management and offers practical insights for promoting resource recovery and sustainability in the construction industry.
