When using this data set for life cycle assessment, special attention should be given to the cut-off criteria based on the ISO140 series of international standards, which focus on material input in relation to product quality. Inclusions and exclusions should adhere to the following specifics: (1) Ignore upstream production data for any ordinary raw material with input weight less than 1% of the total process material inputs or high-purity substances less than 0.1% of the total input weight, provided the total ignored materials do not exceed 5% of the total raw material input. For system environmental emissions data, contributions to LCA outcomes should be calculated prior to deciding on its exclusion. (2) Upstream production data for low-value waste materials used as raw materials, such as tailings, can be disregarded. Users need to ensure that the system boundary of the LCA includes the clinker calcination unit process and apply the data selection principles accordingly. 在使用本数据集进行生命周期评估时，应特别注意依据ISO140系列国际标准中建议的材料投入与产品质量相关的 cut-off 准则。包含与排除应遵循以下具体规则：①对于每种普通原材料输入重量低于总工艺材料输入总量的1%或高纯度物质低于总输入重量的0.1%的原材料，其上游生产数据可以忽略，前提是总共忽略的材料不超过总原材料投入的5%。对于系统环境排放数据，在决定其排除之前应计算其对LCA结果的贡献。②可以忽略作为原材料使用的低价值废料（如尾矿）的上游生产数据。使用者需要确保LCA的系统边界包含熟料煅烧单元过程，并相应地应用数据选择原则。 The data selection principle in this study adopts the cut-off principle recommended in the ISO140 series of international standards. The principle is based on the ratio of raw and auxiliary material input to product quality in the production process. The specific trade-off principle is as follows: (1) When the input weight of each ordinary raw material is less than 1% of the total input weight of process raw materials, and the weight of the raw material containing high-purity substances is less than 0.1% of the total input weight of process raw materials, the upstream production data of the material can be ignored. Additionally, the total mass of the ordinary material ignored should not exceed 5% of the total weight of the raw material input. In the case of system environmental emissions data, its contribution to the relevant LCA result can be calculated to determine whether the data should be ignored. (2) Low-value wastes generated in other production processes, such as tailings, can ignore their upstream production data and use them as raw materials. 数据取舍原则采用ISO140系列国际标准中建议的 cut-off 原则。即以生产过程中各项原辅材料投入与产品质量的比为数据取舍依据。具体取舍原则如下：①当各项普通原料投入重量小于1%过程原料投入总重量，以及原料中含有高纯度物质的重量小于 0.1%过程原料投入总重量时，可忽略该物料的上游生产数据，总共忽略的普通物料质量不超过5%原料投入总重量。如果是系统环境排放数据，则可以先计算其对相关 LCA 结果的贡献值，然后决定该数据是否忽略； ②其他生产过程产生的低价值废料作原料，如尾矿等，可忽略其上游生产数据。 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 2024-04-19T19:01:51+08:00 2024-04-20T14:41:04.702337+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=7f08377f-6bd6-4c34-9efb-fed876e85b60&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 raw meal Input 1420.0 1420.0 Copper -tail ore composite cement raw material 铜尾矿复合水泥生料。实景过程数据。 tap water Input 300.0 300.0 Tap water 自来水。 coal, powder Input 123.6 123.6 coal powder 煤粉。 Electricity Input 99.396 99.396 Electricity.
