Key Data Set Information
Location CN
Reference year 2019
Name
Aluminum electrolysis ; liquid primary aluminum ; prebaked ; alumina for metallurgy
Use advice for data set When using this data set, LCA practitioners should carefully include the relevant energy inputs and material flows as presented in Table 1. It is important to note that transportation assumptions of materials should be critically evaluated and, if necessary, adjusted to reflect the actual situation more accurately. Users should also consider the life-cycle intensities for end-use energy types reported from previous studies, and contextualize these to the specific scenarios they are assessing. This data should ideally be updated with the most recent information available to maintain accuracy in assessments.
Technical purpose of product or process This data set pertains to the industrial process of aluminum electrolysis, which produces liquid primary aluminum using a prebaked method. The alumina used in this process is specifically engineered for metallurgical applications. This primary aluminum can be used in various products ranging from transportation components, construction materials, packaging, to electronic goods.

Data selection and combination principles Inventories of energy input and material flow are collected from updated yearbook s, published papers, official reports and databases. The details of the inventory are presented as Table 1. It should be noted that the data for the material transportation assumptions are based on relevant studies, whic h may be slightly different from the actual situation. The life-cycle intensities of each end-use energy type are based on the results of our previous studies.
