摘要:Since the relationship between supply and demand of natural resources is on edge in the long run, the traditional extensive growth mode of economic development needs changing. Cement is widely used in construction. Producing cement needs large amount of natural resources and releases high waste emissions. By using Material Flow Analysis, the inputs and outputs of each part of manufacturing are analyzed scientifically and the inputs, outputs and efficiency indicators are accounted. The main hidden flows come from energy consumption, and the main harmful waste is CO2 which comes from fuel combustion and CaCO3 decomposition. Improving resource consumption efficiency and reducing CO2 emission are the key ways to alleviate pressures on the environment.
