ACS Sustainable Chem. Eng. 6, 5858–5867 (2018).Users of this data set should apply the allocation method based on market prices of Rare Earth Oxides (REOs) as considered in this study, specifically for the production of 1 kg of NdFeB magnets. When modeling the life cycle assessment, attention should be paid to the methodological advice concerning the inclusion of recycling scenarios or exclusion criteria for materials. It is essential to utilize mass-based allocation as a sensitivity analysis to estimate uncertainties related to the allocation method. The technological applicability mentioned should be carefully adhered to when this data is used in environmental impact analyses or comparisons.使用此数据集的用户应当应用基于稀土氧化物 (REOs) 市场价格的分配方法，如本研究所考虑的，特别是针对1公斤NdFeB磁铁的生产。在模拟生命周期评估时，应注意包括对材料的循环利用情景或排除标准的方法建议。使用基于质量的分配作为灵敏度分析来估计与分配方法相关的不确定性至关重要。在使用此数据进行环境影响分析或比较时，应仔细遵守所提及的技术适用性。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Tao Wang, twang@iue.ac.cn汪涛, twang@iue.ac.cntwang@iue.ac.cntwang@iue.ac.cn2023-12-17T22:57:34+08:002024-04-20T15:07:15.491165+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=9e91e1b0-e38b-408e-8f19-249cd4c462ba&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 usesElectricityInput2.0882.088CalculatedBayan Obo: Value per crushing step; data estimated by experts from RWTH Aachen University, 1.0 kWh/t ore (carbonatite) Bayan Obo: Value per crushing step; data estimated by experts from RWTH Aachen University, 1.0 kWh/t ore (carbonatite) SteelInput0.0120.012CalculatedSteel.
