摘要

Along with the sustained and rapid development of economy in China, especially the rapid urban development, the development of the construction industry has reached a new level. However in the urban development, discarded building materials are problems to which we have to pay attention as well. At present, most of discarded building materials in our country are treated as waste by landfill or outdoor display. These problems have brought huge resource consumption to city and pollute the environment meanwhile. With the lack of energy sources and the aggravation of the environmental problems in our country, ecological utilization of discarded building materials becomes an issue that our country has to face. This paper offers some suggestions for the development of ecological utilization of discarded building materials by comparing between domestic and foreign cases of ecological utilization of discarded building materials.
