Use advice for data set Users of this data set should consider the technological applicability of primary aluminum for their specific intended use, ensuring the material's properties meet the required standards. Data inclusion should consider the energy consumption and emissions associated with coal-based electricity generation, as employed in this study. When applying this data outside of China, users should take into account regional differences in aluminum production processes and related environmental impacts. The infrastructure, anode, and chemicals production data should be reviewed and, if necessary, adapted to local conditions. The service life of buildings and equipment—40 and 8 years, respectively—should inform the depreciation and replacement scheduling in the users' life cycle models.

Data set use approval

General comment 通常，铝电解是通过霍尔-埃鲁过程在电解槽中进行的，这一过程涉及在高温下通过电解熔融铝土矿（氧化铝）来制造金属铝。Life cycle inventory data in operation processes (including energy and raw material consumption) undertaken in Tongchuanxinguang aluminum production site of Tongchuan City in China were mainly collected from reference. Also, coal based electricity generation was used in this study. In addition, in case that China data were not available, data and relevant background data from European were used, including data on infrastructure, anode, and chemicals production. The life time of building and equipment considered in this study is 40 and 8 years, respectively.

Technical purpose The data set describes the production of primary aluminum via the Hall-Héroult process, which involves electrolyzing molten alumina (aluminum oxide) to create the metal aluminum. This liquid primary aluminum is obtained through prebaked electrolytic cells and is intended for use in metallurgy. As such, it is applicable to industries requiring high-grade aluminum including aerospace, automotive, construction, and electronics, where the aluminum's purity and superior properties are critical.
