Reference year 2021
Name
Aluminum electrolysis ; Liquid primary aluminum ; Prebaking ; Alumina for metallurgy ; 2014
Use advice for data set For accurate Life Cycle Assessment of aluminum production using this data set, users should ensure the contextual relevance of the 2014 data to their respective assessment year since technological advancements and efficiency improvements may alter subsequent process outputs. It is important to note that the PA (Primary Aluminum) data is based on statistical sources, while the SA (Secondary Aluminum) data is derived from literature. External LCA practitioners should cross-reference their data with updated databases, keeping in mind the technological applicability fits the locale-specific industry practices. Recycling should be considered where applicable, and background data from the CAS RCEES 2018 database should be used with acknowledgement of its geospatial and temporal context.
Technical purpose of product or process The given data set predominantly describes the process of aluminum electrolysis, which is focused on producing liquid primary aluminum using a prebaking approach from metallurgical alumina in the year 2014.
