Sustainable Mining and Metallurgy

The aluminum industry is the largest source of carbon dioxide emissions in the non-ferrous industry, so reducing carbon emissions in the aluminum industry is an important guarantee for China to achieve carbon peak and carbon neutralization. Based on the carbon emission redution targets of no-ferrous industry and international aluminum industry, combined with the carbon emission status of China’s aluminum industry, China’ s aluminum industry is expected to achieve carbon peak in 2025. The carbon emissions of aluminum industry in China are mainly from raw aluminum production, and the proportion of CO₂ emissions from energy consumption is the largest. There is a large proportion of coal power in the production of electrolytic aluminum in China’s aluminum industry, and the space for the reduction of energy consumption indexes of electrolytic aluminum and alumina is limited. There are still bottlenecks in key carbon reduction technologies, and the production capacity of recycled aluminum is relatively low. In view of the above problems, technical paths such as improving energy utilization efficiency, optimizing industrial structure, optimizing energy structure, and promoting zero-carbon technology innovation are proposed.
