Key Data Set Information
Location CN
Reference year 2009
Name
Aluminum electrolysis ; liquid primary aluminum ; prebaked ; alumina for metallurgy
Use advice for data set When utilizing this dataset for Life Cycle Assessment (LCA), users should ensure that system boundaries are clearly defined, particularly concerning the inclusion or exclusion of the anode production, greenhouse gas emissions, and energy consumption in the electrolysis process. Users should also account for regional variations in the carbon emission factors and update the dataset in line with the most recent published literature on the subject to maintain accuracy in environmental impact assessments.
Technical purpose of product or process This dataset describes the production of liquid primary aluminum through the electrolysis process using a prebaked anode, primarily intended for use in metallurgy. Produced aluminum can be further processed into various forms for manufacturing of transportation vehicles, construction materials, consumer electronics, and other aluminum-based products.
