Use advice for data set | When using this data for LCA studies, consider the age of the data as it reflects the technology and practices from 2011. The PA data should be treated cautiously as it is based on statistical sources that may not fully capture the specifics of the assessed industrial process. The SA data is sourced from literatures and should be checked for relevance and consistency with current processes. Background data is derived from the CAS RCEES 2018 database which provides a Chinese localized LCA perspective; care should be taken when applying this data to different geographic contexts. Additionally, users should account for any developments in technology or practice that have occurred since 2011, which could affect the accuracy of the LCA results. |
Technical purpose of product or process | This data set pertains to the production of metallurgical grade alumina from bauxite in the year 2011. Alumina produced through this process is primarily used for the extraction of aluminum via the electrolytic Hall-Héroult process. The industrial process targets large-scale aluminum production facilities where alumina is a critical input for the smelting operation to produce pure aluminum. |

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. | ||||
