| Use advice for data set | When utilizing this data for Life Cycle Assessment (LCA) of ordinary Portland cement produced using the new dry pre-decomposition cement production technology, ensure to include all relevant phases from the described process boundary. This includes pollutant emission data during limestone and gypsum extraction, transportation of raw materials, and electricity production. The average distance for material transport is considered to be 100km, and emissions data should be obtained from the China Life Cycle Reference Database (CLCD). For auxiliary materials like slag and industrial waste, only incorporate the transportation and preparation stages, excluding the production phase. Note that environmental impacts from the creation of industrial waste should be accounted for by the waste producer. Ensure that the functional unit of the LCA model is consistent with the described unit of 1t of cement. |
| Technical purpose of product or process | The described ordinary Portland cement from new dry process precalciner kilns has applications in the construction industry for building infrastructure, commercial and residential buildings, and other structural constructions. As a binder in concrete, mortar, and other materials, its production technology has been selected for its alignment with environmental protection and high production rates, indicating its suitability for large-scale construction projects that prioritize sustainability. |

| Technology description including background system | This article selects a pre-decomposition kiln-drying cement production model. The new dry pre-decomposition cement production technology is based on suspension preheating and pre-decomposition technology. It is a production technology that is more in line with environmental protection requirements and meets high productivity requirements, and has become the future development trend of China's cement industry. Therefore, the selection of new dry pre-decomposition cement production technology as cement model production technology has advanced and environmentally friendly requirements. |
