Use advice for data set | When utilizing this dataset, users should be aware that recycling processes have not been taken into account. Only direct raw material consumption and direct waste emissions related to the cement manufacturing process are considered within the system boundaries. The missing CO2 emissions data should be supplemented based on site-specific or industry average figures to ensure a comprehensive environmental impact assessment. The functional unit is 1 ton of 525# OPC, with performance categorized as 1Fu=52.5tMPa. This dataset should be used for analyzing the environmental impact of the cement production phase and not for the upstream raw material production or downstream product use stages. |
Technical purpose of product or process | This dataset describes the production of ordinary Portland cement (OPC) with a strength of 52.5MPa using a new dry precalciner kiln technology. This type of cement is primarily used for construction purposes requiring high-strength concrete, such as commercial and residential buildings, infrastructure projects, and other civil engineering constructions. The kiln's co-processing capabilities allow for the incineration of waste, utilizing waste as an alternative fuel and raw material (AFR) in cement manufacturing. |

Model description | Combined with the characteristics of the cement production process itself, the research scope is defined as: from raw material entering the factory, raw material pretreatment, raw meal grinding, raw meal calcination, clinker grinding, until cement homogenization, storage, and packaging. The production and processing process of raw materials is not considered here, only the impact of the production process on the environment is considered, that is, the process of direct raw material consumption and direct waste emissions. Taking the performance of 1 ton of 525# ordinary Portland cement as a functional unit, 1Fu=52.5tMPa. |
