Construction and demolition waste research: a bibliometric analysis

Although construction and demolition (C&D) waste has drawn increasing attention from scholars, there is a lack of study to summarize the latest development of C&D waste research. By using a bibliometric analysis method, this study carries out a holistic review of C&D waste articles published from 1994 to 2017. It shows that the number of C&D waste articles has risen eight-times within the period. This study also demonstrates the social networks among the authors, countries, and organizations. Based on the keywords cluster analysis, the C&D waste research can be divided into five clusters, including (1) environmental concerns of C&D waste; (2) recyclability of C&D waste; (3) performance and behaviour tests of recycled products; (4) C&D waste management; and (5) C&D waste with industrial ecology. Meanwhile, the research status and future directions are discussed as well. The results would be valuable for understanding the streams and trends in C&D waste research.
