BIM-based information system for econo-enviro-friendly end-of-life disposal of construction and demolition waste

Increasing quantities of Construction and Demolition Waste (CDW) have caused serious resource shortages and environmental damage, resulting in the requirements of scientific disposal technologies and methods. In this study, based on the 3R principle, a Building Information Modeling (BIM)-based CDW information system is established using Revit software to reduce the CDW, which overcomes the obstacles of BIM adoption and displays information directly related to CDW. A Reverse Logistics (RL) network is then proposed to regulate the end-of-life disposal of CDW, after which mathematical formulas are introduced to calculate the disposal costs and carbon emissions, to achieve environmental and economic balance. The results showed that the methodology was successfully applied, with precise CDW information obtained for the disposal cost and emission estimations, and high recovery of CDW was guaranteed to achieve sustainable waste development. Efforts can be made on CDW 3D visualization interfaces and the social benefits consideration in future research.
