Therefore, only cement produced by applying dry rotary kiln technology was analyzed.In this enterprise, the flying ash generated from cement production process is recycled as one alternative material for cement production. Wastewater is also recycled for watering local gardens after primary treatment.2013年，中国超过90％的水泥熟料是应用干法旋转窑技术生产的（中国水泥协会，2014）。因此，只分析应用干法旋转窑技术生产的水泥。在这个企业中，水泥生产过程中产生的粉煤灰被回收作为水泥生产的替代材料之一。废水经过初步处理后也被回收用于浇灌当地的花园。13In this enterprise, the flying ash generated from cement production process is recycled as one alternative material for cement production. Wastewater is also recycled for watering local gardens after primary treatment.In this enterprise, the flying ash generated from cement production process is recycled as one alternative material for cement production. Wastewater is also recycled for watering local gardens after primary treatment.The described process produces portland-composite cement using dry rotary kiln technology. It applies specifically to cement production processes where mixed solid wastes are utilized. The cement generated is suited for construction activities, especially where a blend of clinker and supplementary cementitious materials like fly ash is acceptable. The fly ash utilization aligns with sustainable practices by reducing the need for virgin raw materials and minimizing waste.所述工艺使用干法回转窑技术生产复合硅酸盐水泥。它特别适用于使用混合固体废物的水泥生产过程。生成的水泥适合于建筑活动，特别是在允许使用熟料和补充性胶凝材料（如粉煤灰）混合的情况下。通过减少对原始原材料的需求和最小化废物，粉煤灰的利用符合可持续实践。VtuJbmtbioKBvcxpMPBcxki6nKh.pngSystem boundaries are set using a cradle-to-gate approach, i.e. excluding cement use and final disposal.Take 1 ton of cement product as the functional unit.系统边界采用从摇篮到大门的方法进行设置，即不包括水泥使用和最终处置。以1吨水泥产品为功能单位。LCI resultNone无None无None无The data comes from one of the top 50 cement production companies in China that can represent the current level of cement production in China. Annual monitoring data (i.e. raw material and energy consumption, and air emissions) were obtained from the enterprise's annual operational data.数据来源于可以代表当前中国水泥生产水平的中国前50家水泥生产企业之一。年度监测数据（即原材料和能源消耗，以及空气排放）是从该企业的年度运营数据中获取的。None无None无Wei Chen, Wenjing Liu, Yong Geng, Satoshi Ohnishi, Lu Sun, Wenyi Han, Xu Tian, & Shaozhuo Zhong.

JOURNAL OF CLEANER PRODUCTION, 131, 272–279. When using this LCA dataset, note that it only accounts for the production phase of cement using dry rotary kiln technology and excludes the use and disposal phases. Ensure the inclusion of recycled materials such as fly ash in the analysis as it represents a key element of the ecological efficiency of this process. Data users should account for local recycling practices, and the potential environmental benefits of wastewater reuse. This dataset is representative of a major Chinese cement producer and should be contextualized when comparing with other regions or production technologies.使用此LCA数据集时，请注意它仅涵盖使用干法旋转窑技术的水泥生产阶段，并排除了使用和处置阶段。确保在分析中包括诸如粉煤灰这样的回收材料，因为它代表了这一过程生态效率的关键元素。数据使用者应考虑当地的回收实践，并且潜在的废水再利用环境效益。此数据集代表了中国主要的水泥生产商，在与其他地区或生产技术比较时应该进行情境分析。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.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:41:44.716965+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=5b9238bb-eae4-4f93-a7de-641b6cf0b647&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usescalcium carbonateInput1050.01050.0Limestone石灰石ElectricityInput295.0295.0Electricity电hard coalInput91.8105031291.81050312Soft Coal.
