Key Data Set Information
Location CN
Reference year 2021
Name
Aluminum electrolysis ; Liquid primary aluminum ; Prebaking ; Alumina for metallurgy ; 2015
Use advice for data set When using this data set, it is critical to consider the specific year (2015) as the technology and energy efficiency may have evolved since then. As this data is region-specific (Chinese LCA context), it should be used for LCA studies within the corresponding geographical scope or with careful consideration for adjustment to represent other regions. For methodological consistency, users should note that PA data is derived from statistical data sources, SA data mainly from existing literature, and background data from the Chinese localised CAS RCEES 2018 database. Ensure that these data sources are compatible with the goal and scope of the LCA being conducted.
Technical purpose of product or process This LCA data set represents the aluminum electrolysis process used to produce liquid primary aluminum with a prebaking step, using metallurgical grade alumina. The process is applicable to the synthesis of high-purity aluminum used in various industries, such as aerospace, transportation, electronics, and building materials. The primary aluminum produced through this process would typically be cast into ingots, billets, or other forms for further fabrication or direct use in manufacturing.

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.
