| Use advice for data set | When using this data set for Life Cycle Assessment (LCA), ensure to include the complete system boundary spanning raw material crushing, clinker generation, and cement milling stages. Pay special attention to the allocation of environmental loads regarding the 100% recycling of cement dust and reuse of wastewater on-site. Methodological considerations should cover the sourcing of emission data due to reported information gaps, and adjustments may be required based on the technological differences between referenced facilities (Shenfeng Cement Co., Ltd. and Yunnan Hongda Cement Plant). |
| Technical purpose of product or process | The data set describes a large-scale dry rotary kiln operation for the production of common Portland cement. This process is mainly applied for the generation of clinker at a rate higher than 4000 tons daily. The recycled cement dust and reused wastewater underscore an environmentally considerate manufacturing practice. The cement produced here is typically used in construction, and is the predominant form of cement in the Chinese market, comprising about 98% of the total cement production. |

| 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.Dry rotary kiln system boundary. Three stages are usually considered, namely raw material crushing, clinker generation and cement mill. The clinker generation stage includes homogenization, preheating and precalcining as well as 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. |
