The PA data were obtained from statistical data sources, and the SA data were mainly obtained from the literatures. The background data were mainly derived from the Chinese localization LCA database CAS RCEES 2018, which was established by the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences and covers LCA data for energy, materials, transportation, waste management etc.本研究的数据参考了PA、SA、电力等背景数据的LCA数据。PA数据来自统计数据源，SA数据主要来自文献。背景数据主要来自中国科学院生态环境研究中心CASRCEES 2018建立的中国本地化LCA数据库，涵盖能源、材料、交通、废物管理等LCA数据。None无None无Ding, N., Liu, N., Lu, B. & Yang, J. Life cycle greenhouse gas emissions of aluminum based on regional industrial transfer in China. J. Ind. Ecol. 25, 1657–1672 (2021). Ding, N., Liu, N., Lu, B. & Yang, J. Life cycle greenhouse gas emissions of aluminum based on regional industrial transfer in China. J. Ind. Ecol. 25, 1657–1672 (2021). Users of this LCA data set should be aware that the data applies specifically to the production of alumina intended for metallurgical purposes, using bauxite as the precursor, and is representative of the technological practices in 2008. When applying this data in life cycle assessments, incorporate data consideration for potential updates or technological changes that may have occurred post-2008. Background data originates from the Chinese-specific LCA database, focusing only on the processes relevant to PA, SA, electricity, and other background data as described. It's important to ensure appropriateness in regional context and alignment with the goal and scope of the assessment, and to pay attention to the methodological consistency, especially when dealing with international comparisons or integrating with global data sets.使用此LCA数据集的用户需知，该数据专门适用于以铝土矿为前体，用于冶金目的的氧化铝生产，并代表2008年的技术实践。在进行生命周期评估时，应考虑潜在的更新或技术变化，这可能在2008年之后发生过。背景数据来源于中国特定的LCA数据库，仅关注PA，SA，电力和其他如所述的背景数据。在区域背景下确保数据适用性，以及与评估的目标和范围保持一致是重要的，并且在处理国际比较或与全球数据集整合时需要注意方法论的一致性。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Yuzhen Feng, fyz22封羽真, fyz22fyz22fyz222024-01-10T09:09:36+08:002024-04-20T15:31:30.407027+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=82e2ed69-93ab-48cc-9240-fc64b80d7b94&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 usessoda ash, denseInput123.21123.21soda ashPetroleum CokeInput1653.0397866361653.039786636Energy sources proportion of energy consumption is coal: fuel oil: coke: natural gas: coke even gas=46.0%: 11.0%: 7.1%: 14.1%: 21.7%coal gasInput5052.2483619725052.248361972Energy sources proportion of energy consumption is coal: fuel oil: coke: natural gas: coke even gas=46.0%: 11.0%: 7.1%: 14.1%: 21.7%natural gas, high pressureInput3282.7973227563282.797322756Energy sources proportion of energy consumption is coal: fuel oil: coke: natural gas: coke even gas=46.0%: 11.0%: 7.1%: 14.1%: 21.7%fuel oil, unspecifiedInput2561.04755675999972561.0475567599997Energy sources proportion of energy consumption is coal: fuel oil: coke: natural gas: coke even gas=46.0%: 11.0%: 7.1%: 14.1%: 21.7%hard coalInput10709.8352373610709.83523736Energy sources proportion of energy consumption is coal: fuel oil: coke: natural gas: coke even gas=46.0%: 11.0%: 7.1%: 14.1%: 21.7%Water, unspecified natural originInput3.493.49water consumptionaluminium oxide, metallurgicalOutput1000.01000.0alumina
