| Use advice for data set | This LCA data set is based on market shares of different cement production technologies and their scale of operation. Users should note that the average data reflects the weighted consumption of raw materials across various production scales and technologies, including large, medium, and small new dry process facilities, as well as shaft kilns. The methodological consideration must be the use of this data in the context of cement with a 70% clinker content. The data assumes China-specific technology mix and should only be used as such without extrapolation to other regions without appropriate adjustments. Furthermore, users looking to study specific types or qualities of cement production should acquire more detailed data rather than relying on this average. |
| Technical purpose of product or process | The described data set is intended for representing the environmental impacts of average cement production processes in China, specifically for general Portland cement. The information is relevant for studies on the construction industry, where cement is a fundamental material for building infrastructure, commercial and residential buildings, and for creating concrete by mixing with aggregates and water. |

| General comment on data set | The average data for China are based on market shares for each cement production process technology and size, and the respective raw material consumption. Market shares of cement production process technologies and sizes: large new dry process (>4000 t-clinker/day), 29.32%; medium new dry process (2000-4000 t-clinker/day), 23.21%; small new dry process (<2000 t-clinker/day), 9.29%; shaft kiln (<2000 t-clinker/day), 38.18%. |
