Name
Aluminum electrolysis ; Liquid primary aluminum ; Prebaking ; Alumina for metallurgy ; 2007
Use advice for data set This LCA data set should be used with consideration of its technological and temporal relevance. Users must note that the data pertain to the prebaking electrolytic process for aluminum production in 2007 and may not reflect current technologies or environmental conditions. When applying this data set in broader environmental impact studies, users should account for any advances in technology and changes in emissions or energy efficiency that have occurred since 2007. Furthermore, researchers should ensure that the background LCA data from the CAS RCEES 2018 database is compatible with their study goals and that any significant differences in geographic, technological, or temporal scopes between the study and data source are appropriately addressed.
Technical purpose of product or process The described process relates to the production of liquid primary aluminum by the prebaking method, using alumina specifically processed for metallurgical applications. This industrial process is generally applied in the production of aluminum for use in diverse sectors such as construction, transportation, electrical systems, and consumer goods manufacturing. The data from 2007 reflects the technological state of the industry at that time and might guide the choice of technology or process assessment in historical analyses or comparisons with newer technologies.

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.
