Description

The industrial process described relates to the production of liquid primary aluminum by means of electrolysis. This process involves the prebaking stage and uses alumina specifically designed for metallurgical applications. The primary aluminum produced through this process is used in various sectors such as transportation, construction, electronics, and packaging due to its properties of high conductivity, low density, and resistance to corrosion. The year indicated, 2017, suggests that the data correspond to the technological standards and practices of that time. The LCA data provided should be considered with the context of the technology and practices of the year 2017; hence, updates in technology or efficiency changes since then must be taken into account when using this data. The Primary Aluminum (PA) and Secondary Aluminum (SA) data inputs should be verified with contemporary statistical sources to ensure relevance. Users should refer to the CAS RCEES 2018 database for background data relevance and ensure alignment with the geographical context of China. Attention should be given to methodological considerations, such as the inclusion or exclusion of recycling processes in the lifecycle and the specific use-phase behaviors that need to be modeled. Further, it may be necessary to consult with updated emissions factors and environmental impact data for a more current assessment.
