Use advice for data set | Users of this LCA data should note that the dataset is representative of alumina production for the metallurgy of primary aluminium as of 2015, following data from the International Aluminium Institute (IAI). It covers the unit process (singular operation) and accounts for inputs and background processes contributing to at least 1% of the total input mass. When applying this data, acknowledge that some inputs and processes may have been excluded due to their minimal contribution. Take care to use the data within its intended context, specifically in modeling the environmental impacts of primary aluminium production. Reconciliation with newer data is advised when available to account for technological and methodological advances. |
Technical purpose of product or process | The alumina produced in this industrial process is intended for use in metallurgical applications, specifically in the production of primary aluminium. This high purity alumina is sourced from bauxite and is an essential raw material for the aluminium industry. Its usage includes serving as a precursor for the electrolytic process of aluminium extraction in smelters. |

Data selection and combination principles | For reliable findings, the most recent and representative data were considered. Regional or country-specific data were used when provided in the GaBi© “professional and extension” database (SP 39) or in the literature. If location-specific data were not found, either comparable data for the country or global data were used. For consistency, data from the same source and year were used if available. Due to data availability, the study did not consider some inputs and background processes if they contributed less than 1% to the total input mass. For primary aluminium production, this study used the most recent LCI data from 2015 provided by the International Aluminium Institute (IAI) (International Aluminium Institute, 2017b). IAI data were used because the IAI is an established institute that considers primary aluminium production worldwide and the data were used in studies e.g. from the Aluminium Association and from the European Aluminium Association (Aluminum Association, 2013; European Aluminium Association, 2018). In terms of the LCA data of standardized primary aluminium production, only few uncertainties occurred. Generally, the composition of these data could be fully explained and reconstructed. | ||||
