Abstract
Abstract Urban mining has been promoted globally in order to recover secondary resources. In this paper, a bibliometric and visual analysis on urban mining related research articles collected from the Web of Science (WOS) database between 1993 and 2018 was conducted. The results show that in total 277 publications were published in 108 journals. Waste management, Journal of Cleaner Production, and Resources Conservation & Recycling were the top three most productive journals. 501 authors published their urban mining related papers and the top three most productive authors are Krook J, Hogland W, and Fellner J. Based on co-citation cluster analysis, the intellectual bases and research hot topics on urban mining were analyzed. The co-citation network was divided into 7 clusters, including enhanced landfill mining, metal recycling, e-waste, urban mining, landfill mining, metal stocks, and GIS. Finally, keywords burst detection was conducted to track the hot topics and research trend. The hot topics have switched from recycling, metal stock, and life cycle assessment to waste electrical and electronic equipment. This study provides a research landscape and future research directions of urban mining research so that future researchers can identify their research topics and partners.
