Abstract:
Construction and demolition waste (CDW) is estimated to make up one-third of the total solid waste in the world, which is a significant problem in terms of environmental, economic and social impacts. The existing disposal modalities with special reference to landfilling and open dumping contribute to the depletion of resources and increase risks to the health of people. This review clarifies how the key principles of a circular economy, life-cycle analysis, and the waste hierarchy can be used to increase the sustainability of CDW management. Among the major policy interventions, regulatory reforms supported by economic incentives, full stakeholder involvement, and application of digital platforms, including Building Information Modeling (BIM), the Internet of Things (IoT), and blockchain technology to enhance waste tracking and transparency, should be mentioned. The use of technological innovations, such as artificial intelligence, unmanned aerial vehicles, robotic sorting systems, and so on, can additionally allow making the recovery of resources optimized, planning early, and also modular design and pre-demolition inspection minimize waste production at the outset. The attainment of sustainable CDW management requires a combined set of policies, technological breakthrough and synergistic behavior change. The next generation of priorities should be based on the establishment of global harmonized standards, improving the data interoperability and scaling digital tools to establish a low-waste, circular building industry in line with the sustainability goals of the world at large.
