Use advice for data set When using this LCA data set, it is important to align the system boundaries accordingly and use the data consistently with the technological era it represents. Special attention should be paid to whether the data applies to the geographic and technological scope of the assessed process. Users should also be aware that LCA results may vary based on advances in technology since 2008 and differences in regional practices. Background data should be appropriately sourced from the CAS RCEES 2018 database or other relevant databases to maintain accuracy.
Technical purpose of product or process The industrial process described is the production of liquid primary aluminum through the prebaking electrolysis method using metallurgical grade alumina. This primary aluminum is commonly utilized in a variety of industries such as automotive, construction, electronics, and packaging due to its lightweight, conductivity, and corrosion-resistant properties. The specific reference year for this data set is 2008, indicating the technological practices and efficiencies of that time.

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.
