| Use advice for data set | When using this dataset for Life Cycle Assessment (LCA), pay particular attention to the system boundaries and stages defined within the shaft kiln cement production process. It includes stages such as raw material crushing, clinker generation, and the cement milling process. Ensure that transportation, direct emissions, energy consumption, and infrastructure are also included in the analysis, as they are critical for the LCA of cement production. Be sure to incorporate the provided recycling rates for cement dust and apply the specific direct emissions data accordingly. Utilize the China Cement Industry Cleaner Production Standard (HJ 467-2009) for direct SO2 and NOx emissions to ensure conformity with local regulations when assessing environmental impact. |
| Technical purpose of product or process | This dataset describes the production process of common Portland cement using a shaft kiln. The cement produced is primarily used for construction purposes and is fundamental in the manufacturing of concrete and other building materials. With ordinary Portland cement making up approximately 98% of the cement production in China, this data can be utilized to understand the environmental impact of large-scale cement production specific to China's standards and technologies. |

| Model description | Taking the production of 1 ton of ordinary Portland cement as a functional unit, this type of cement accounts for approximately 98% of total production in China.System boundaries for shaft kilns. Three stages are usually considered, namely raw material crushing, clinker generation and cement mill. The clinker generation stage includes mixing water, pelletizing and firing in the kiln. Each process takes into account raw materials, energy consumption, road transport, direct emissions (i.e. carbon dioxide, sulfur dioxide, nitrogen oxides and particulate matter) and infrastructure. |
