Bibliometric Analysis of Global Research Trend on Construction and Demolition Waste in Past Two Decade

Abstract

A bibliometric analysis of current research trends in the field of construction and demolition waste is presented in this work. The analysis is based on the type of document, language, distribution of the journal, subject category, countries, and author keywords. This study uses data gathered from the Web of Science database for the years 2002–2021. A cubic regression model has been created to predict publication output in the upcoming decade. Based on the model, the publication on construction and demolition waste is expected to exceed four times that of 2021 by the end of the forthcoming decade. The most prevalent subject category is engineering. Construction and building materials is the most productive journal. The social network analysis reveals that People ‘R’ China is the most influential and collaborative country. Finally, the author's keyword is analyzed to find out the research hotspot. The results showed construction and demolition waste, recycling, construction waste, waste management, and recycled aggregate were the most frequently used keywords. This study gives an overview of research on construction and demolition waste and helps in identifying the pattern of research around the world and plan for future research.
