The company's production process uses RSP five-stage kiln external decomposition technology, and mainly adopts advanced production equipment from Germany, France, Japan, and some domestic companies. The cement production line consists of a vertical raw mill, a 5-stage RSP (kiln external pre-decomposition tower), a rotary kiln, and a large ball mill equipped with a roller press, as well as gypsum crushing, limestone grinding, and conveying and adding equipment. Users of this LCA dataset should be aware that it includes production process data from DOCC, which applies advanced RSP kiln external decomposition technology. Data was not modeled using LCA methodology but was obtained through on-site surveys and indirect calculation of energy and raw material conversion due to the lack of direct industrial pollutant emissions data. Users should also note potential methodological differences and understand that the dataset may not include end-of-life recycling or use-phase behavior modeling. It's recommended to cross-reference this data with the latest available standards and industry practices, especially regarding emission factors and environmental impacts.
