Name
Aluminum electrolysis ; Liquid primary aluminum ; Prebaking ; Alumina for metallurgy ; 2011
Use advice for data set Users of this LCA data should note that the primary aluminum (PA) data sourced from statistical data and secondary aluminum (SA) data primarily derived from literature must be contextualized within the technological framework of 2011. Background data from the Chinese localized LCA database CAS RCEES 2018 should be used with an understanding that it reflects the environmental impacts associated with energy, materials, transportation, and waste management specific to the Chinese context. It is recommended to account for any changes in technology or environmental regulations when applying this data to current scenarios.
Technical purpose of product or process The aluminum electrolysis process described is specifically designed for producing liquid primary aluminum through a prebaking step using alumina for metallurgy. This primary aluminum is typically used for manufacturing various aluminum products, such as construction materials, automotive parts, electrical components, and packaging. The specific year of the data indicates that this process applies to technologies and methodologies used in 2011.

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.
