| Use advice for data set | When using this dataset in Life Cycle Assessment of cement products, it is necessary to account for the specific production technology (medium new dry process) and the scale of operation representing medium-sized cement plants. Users should consider the typical market share and ensure the representative nature of the data when applying it to environmental impact studies. Variations in technology and scale between different companies in China's cement industry should influence the selection and application of this data. |
| Technical purpose of product or process | The medium new dry process used in this dataset refers to the production of common Portland cement with a daily clinker production rate of 2000 to 4000 tons. This cement is utilized broadly in the construction industry for creating concrete, precast structural elements, and other building materials. The production technique is significant as it represents a balance between output capacity and environmental considerations in China's cement industry, being applicable mainly to medium-scale cement plants. |

| General comment on data set | The new dry process method holds a market share of 61.82%, and the scale of the clinker production between 2000 and 4000 tons per day accounts for 23.21%. In order to reflect the present environmental impact of China's cement industry, taking into account the adjustment of the industry structure and development status in recent years, and considering the differences in cement production technology and the size of different enterprises, China's cement industry is classified into four categories: large new dry process (>4000 tons of clinker per day), medium new dry process (2000~4000 tons of clinker per day), small new dry process (<2000 tons of clinker per day), and shaft kiln (<2001 tons of clinker per day). |

| Technology description including background system | The new dry method accounts for 61.82% of the market share; 2000~4000 tons-clinker/day, the scale share accounts for 23.21%. In order to reflect the environmental impact of China's cement industry at this stage, combined with the structural adjustment and development status of China's cement industry in recent years, and taking into account the level of cement production technology and the differences between cement companies of different sizes, this study divides China's cement industry into the following four categories : Large new dry process (>4000 tons-clinker/day), medium-sized new dry process (2000~4000 tons-clinker/day), small new dry process (<2000 tons-clinker/day) and vertical kiln ( <2000 tons-clinker/day). |
