A Critical Review of Recycling Facility Location and Optimization Methods for Construction and Demolition Waste

In the process of large-scale urban construction, a large number of construction and demolition waste (C&DW) are produced, the rapid economic construction has brought better living conditions for people. However, the recycling rate of the C&DW in China is very low, which has caused great pressure on the resources and environment. Based on Citespace, this paper makes a scientometrics visualization analysis of the research papers in the field of C&DW from 2000 to 2021 in Scopus database. Through the frequency of keywords and clustering analysis, the high-frequency keywords in the research process of this field are “Waste management”, “Recycling”, “Demolition” and “Construction and demolition waste”. After expanding the scope of co-occurrence, it is found that the low-frequency keywords such as “Site selection” “Optimization” “Environmental impact assessment” and “Environment management” are associated with the high-frequency keywords. From the perspective of time zone, it is found that the future research of C&DW will focus on the innovation of recycling facilities and the optimization of recycling plant location. This paper analyzes the optimization method of site selection of C&DW recycling facilities, and puts forward some suggestions to improve the utilization rate of building demolition waste and reduce the burden on the environment.
