CO2 emissions from typical cement plants in China

The objective is to know how the CO₂ emits and how much the CO₂ emits due to the cement manufacture in both direct and indirect ways with the increasing concerns about the global warming and the cement plants emitting huge CO₂. A precise method to calculate CO₂ emissions including three processes was established in this paper and a case study was provided. From the case of 23 typical plants in China, we can see the amount of CO₂ emissions at the right level. The summary of CO₂ emissions consists of emissions from raw materials, fuels and electricity. The average result of the 23 typical plants is 0.74 t CO₂ per ton clinker in this study. Therefore, CO₂ emissions from these typical cement plants were pictured and then measured. The creative point is that an approach provides a basic framework to identify various situations in different cement plants in China and other in the rest of the world. The framework would be useful in quantitatively evaluating CO₂ emissions for government to know precisely CO₂ emissions in the cement plants.
