When utilizing this LCA data, users should note that the dataset represents the production of 1kg of P·O 32.5 ordinary Portland cement and includes processes from raw material mining to cement storage. This data is specific to the shaft kiln technology at Guangzhou Shijing Cement Plant and includes the usage of mixed solid wastes as part of the raw material blend. It's important to note that the industrial waste residues used in the process are not considered in the pollutant emissions. Users should apply this data within its technological applicability scope and take into account the methodological advice when integrating this dataset into broader LCA studies. 使用此生命周期评价数据时，用户应注意数据集代表了1kg P·O 32.5 普通硅酸盐水泥的生产，并包括从原材料开采到水泥储存的过程。这些数据特定于广州石井水泥厂的立窑技术，并且包括了固体废物混合物作为原料配比的一部分。值得注意的是，工艺中使用的工业废渣在污染物排放数据中未被考虑。用户应在其技术适用范围内应用此数据，并在将此数据集纳入更广泛的生命周期评价研究时考虑方法论建议。 Industrial waste residues, including slag, fly ash, phosphogypsum, and ceramic polishing waste, are not considered as resource consumption for industrial solid waste, and thus no pollutant emissions are accounted for. 工业废渣包括矿渣、粉煤灰、磷石膏、陶瓷抛光废料，对工业固体废弃物不考虑作为资源消耗，故没有污染物排放。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 #REF!, ysqsophia@gmail.com ysqsophia@gmail.com ysqsophia@gmail.com 2024-03-19T21:18:09+08:00 2024-04-20T14:41:07.002811+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=1c1251bf-2558-47d6-ada1-39e9392eca35&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses calcium carbonate Input 1133.0 1133.0 Limestone.
