Name
Aluminum electrolysis ; Liquid primary aluminum ; Prebaking ; Alumina for metallurgy ; 2010
Use advice for data set Users of this LCA data set should ensure that they are applying it to scenarios appropriate for the metallurgical grade aluminum production. The primary aluminum (PA) and secondary aluminum (SA) data shall be considered based on statistical and literature sources respectively. It is critical to utilize the background data from the Chinese localization LCA database CAS RCEES 2018 accurately. Users should take care to apply the data consistently with the technological scope being modeled and pay special attention to methodological choices regarding the inclusion or exclusion of recycling impacts in the LCA model. The vintage of the data (2010) should be taken into account when assessing the relevance and accuracy for current applications.

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.
