Sustainable Management of Construction and Demolition Waste: A Bibliometric Analysis and Technological Innovations During 2001-2023

Abstract

The rapid pace of urbanization has escalated the production of Construction and Demolition Waste (CDW), reaching approximately 10 billion tons annually. CDW, comprising diverse materials such as concrete, bricks, asphalt, wood, glass, metals, and plastics, poses significant environmental challenges due to the presence of hazardous substances like asbestos and mercury. Effective management and recycling of CDW can transform waste into valuable resources for new construction, thereby reducing the need for raw material extraction and processing. This study employs bibliometric analysis to explore global research trends in sustainable CDW management from 2001 to 2023, utilizing data from the Scopus database. The analysis reveals a significant increase in publications and citations over time, with a predominant focus on environmental science and engineering. China, India, and the United Kingdom are identified as the leading contributors to this field. Key research themes include greenhouse gas emissions, carbon footprint, and human factors influencing waste management. The study underscores the importance of integrating advanced technologies such as Building Information Modelling (BIM) and 3D printing in promoting sustainable practices. The findings highlight the necessity for continued innovation and international collaboration to address the global challenge of CDW.
