| Use advice for data set | Users of this dataset should pay attention to the weighted average CO2 emission factor generated during the electrolysis of aluminum, which is based on a distribution ratio of aluminum production using different processes within China. Special attention should be given to data from the year 2011 as it is the primary source for the carbon emission factors database for alumina and aluminum electrolysis processes. The dataset includes sub-databases for raw & auxiliary material consumption and waste generation, technological processes & equipment, materials & energy consumption in processes, and secondary energy production in self-provided thermal power plants. When modeling, users should include the scope of carbon anode consumption in the electrolysis process, PFCs emissions, and the production process of purchased electricity. It is also advised to consult Table 1 of the source literature for a detailed understanding of the database structure and to ensure the inclusion of all relevant technological factors for accurate lifecycle assessment. |
| Technical purpose of product or process | The technical usage of the described process is for the production of liquid primary aluminum, employing the southern China power grid in the electrolysis process. Alumina for metallurgy is used as a raw material. This primary aluminum is typically used for manufacturing various aluminum products such as sheets, foils, wires, and extrusions. It serves as an input material for sectors that produce transportation vehicles, packaging, building components, and electrical applications due to its properties such as light weight, conductivity, and corrosion resistance. |
