Exploring the trends in construction and demolition waste (C&DW) research: A scientometric analysis approach

Purpose: The study aims at (i) summarizing construction waste management studies from 2013 to 2022; (ii) understanding the current state of the body of knowledge, as well as keyword co-occurrence, document cocitation, cluster analysis, and visual maps; and (iii) identifying the research gap in the construction waste management studies, including gaps in major knowledge domains, and (iv) providing future directions for research areas in the construction waste management. Methodology: We apply the scientometric analysis approach, which maps the visualization review of a particular knowledge domain. Using the proximity analysis method, a relational analysis of concepts in published studies were conducted. This analytical method is employed to ascertain the association between a selected point and its neighbors. We developed a concept matrix and a group of linked co-occurring terms that suggested a larger meaning using this method. Findings: A total of 974 authors from 61 different countries contributed to the 375 full text research publications on the construction waste management that were indexed in Scopus between 2013 and 2022. The top three authors in terms of output were; Lu W (15 publications), Tam V.W.Y (14 publication), and Zuo, J (10 publications). The author with the most citations is Lu W., who has 648, followed by Yuan (731), and Tam V.W.Y. (610). It was discovered that China, Australia and Hong Kong had a significant influence on how construction waste management was used. The analysis revealed that the most active research fields at the moment are demolition, sustainable development, waste disposal, environmental impact of construction waste, waste recycling, reduction, and reuse. Originality: The study presents the results of a recent, updated scientometric analysis from 2013 to 2022, which identified the construction waste management field's most active authors, countries, journals, publication trends, affiliation, funding sponsors, and research areas. This study will provide a pathway for the upcoming researchers to follow the construction and demolition waste (C&DW) trends to add in the body of knowledge and contribute to the (C&DW), knowledge domains.
