With the continuous recommendation of the urbanization process in China, the production of construction waste is also increasing. At present, the utilization of construction waste resources in China is relatively low, mostly landfilling disposal. The environmental problems caused by landfill disposal are becoming more and more serious, but also a great waste of resources. Fine classification of construction waste source is the premise and key to promote the precise management and control of construction waste. This paper makes a thorough investigation and literature analysis on the classification methods of construction waste in developed countries abroad and the Post-disposal modes brought by classification. Based on the current situation and existing problems of classification of construction waste in China, six first-level classification and 28 second-level classification are proposed. The results of construction waste and the feasibility of the results are discussed and analyzed in order to provide reference for the classification of buildings in China.
