In terms of environmental protection, we have been committed to the recycling of renewable aluminum resources for 38 years, promoting the lightweight research and application of aluminum instead of steel and aluminum instead of copper in automobile and rail transit products. Always regard environmental protection as our important social responsibility. We have the ability to analyze and manage low carbon emissions of aluminum alloy and aluminum alloy products throughout their life cycle; It has a wide range of renewable aluminum recycling channels and a large-scale production capacity of renewable aluminum resources utilization. Each ton of recycled aluminum we recycle can reduce the emissions of CO₂ and SO₂ by about 11 tons, save electricity by about 13000 degrees, reduce ore mining by about 11 tons, discharge solid waste by about 20 tons, and save 22 cubic meters of water for the world. In 2021, we will save 6.3 billion kilowatt-hours of electricity globally, reduce ore mining by about 5 million tons, save water by about 10 million cubic meters, reduce emissions of CO₂ and SO₂ by about 5 million tons, and reduce emissions of solid waste by about 9 million tons. Contribute to the realization of carbon peak and carbon neutrality in China.
