Use advice for data set LCA data users should pay close attention to the scope and technological applicability of this dataset. The data set is specific to the year 2012 and may not accurately reflect current production processes or environmental impacts. Recycled material flows should be clearly distinguished and excluded if the analysis is strictly about primary production. When applying the LCA data on electricity and background data from CAS RCEES 2018, the geographical relevance and updates to the methodology or database should be considered. For any comparison, ensure temporal alignment and consistent system boundary with the studied processes.
Technical purpose of product or process The liquid primary aluminum produced from the industrial process of aluminum electrolysis, using the prebaking method, is intended for usage in the metallurgy industry. This aluminum produced in 2012 is especially suited for large-scale manufacturing processes that require high-purity aluminum, such as aircraft, automotive parts, construction materials, and other applications where the properties of aluminum are indispensable.

Data selection and combination principles The data in this study refers to the LCA data of PA, SA, electricity, and other background data. 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.
