Use advice for data set | When utilizing this LCA data set, users should be aware that the Process Analysis (PA) and Substance Analysis (SA) figures are based on statistical data sources and selected literature, respectively. The dataset also includes background information derived from the Chinese localized LCA database, CAS RCEES 2018. It is pertinent to understand that the technological applicability is specific to the year 2009 and Chinese context. Additionally, users must pay attention to the methodological consistency when integrating this data with other LCA datasets, especially considering recycling and use phase behavior specific to alumina and aluminum production. |
Technical purpose of product or process | The data represents the life cycle assessment (LCA) parameters for the production of alumina used in metallurgy. It's primarily extracted from bauxite and is an essential raw material for aluminum production. As of 2009, this particular alumina quality is utilized in large-scale aluminum refining processes where the high purity level is critical for the production of metallic aluminum through electrolysis. |
