Use advice for data set | When utilizing the Life Cycle Assessment data of the prebaked aluminum electrolysis process for liquid primary aluminum, users should pay particular attention to the completeness of the environmental data for each production stage referred to in the provided statistics. It's necessary to confirm that all relevant environmental impacts have been accounted for adequately, including energy consumption, direct and indirect emissions, and any wastes generated. Moreover, variations in technology and operational efficiency between different producers could lead to variable data; thus, site-specific information should be prioritized if available. Lastly, consider any methodological assumptions that are pertinent to recycling content and end-of-life treatment in alignment with the goal and scope of the specific LCA study. |
Technical purpose of product or process | The product, liquid primary aluminum obtained via the prebaked aluminum electrolysis process, is used for a wide array of metallurgical applications. It serves as a raw material in the production of aluminum-based components and products including automotive parts, construction materials, electrical conduits, and aerostructural components. Its high purity makes it suitable for demanding applications that require superior strength, light weight, and corrosion resistance. |

Data selection and combination principles | In this paper, the production of primary aluminum at all stages is based on the statistical data in the non-ferrous metal industry yearbook as the main reference basis. For some non-statistical process data, they come from the research of production process and technical indexes of typical enterprises ...... Pollution emission in specific production stages is based on the internal statistical data of enterprises obtained from the research and part of the research results from the literature are referred to. | ||||
