Use advice for data set | When utilizing this dataset for Life Cycle Assessment, include the impacts of energy and resource consumption, emissions of dust, SO2, and NOx during cement production phases of raw meal preparation, clinker burning, cement grinding, and packaging and delivery. Note that CO2 emissions should be accounted for by their specific sources. Emission factors from Gao Changming's research should be used for JT shaft kiln emissions not published elsewhere. Thermal consumption data must be normalized by dividing by 0.7 to represent unit cement heat consumption appropriately. |
Technical purpose of product or process | The data set represents the use of the JT shaft kiln process for the production of ordinary Portland cement. Applicable for the construction industry, this cement is commonly used in building materials for constructing infrastructures such as roads, bridges, and buildings. |

Data selection and combination principles | The resource consumption data adopts the research results of Li Songbing. The energy consumption comes from the data published by the Cement Industry Association and refers to the "2010 Cement Industry Risk Analysis Report". The emission coefficients of powder (smoke) dust and SO2 and NOx pollutants in the exhaust gas adopt the 2008 China Statistical results of pollution source census; CO2 emissions are estimated according to their sources. The research results of Gao Changming were used for the unpublished emission coefficient of JT vertical kiln. | ||||
