The group attaches great importance to environmental protection work and consciously strengthens environmental protection governance. In recent years, it has invested 10 billion Yuan to strengthen environmental protection governance and has taken the lead in the industry to achieve ultra-low emissions of thermal power units, alumina, and electrolytic aluminum. After the ultra-low emission of thermal power generators, the pollutant sulfur dioxide, nitrogen oxides, and soot emission concentrations are respectively about 15 mg/m3, 25 mg/m3, and 1 mg/m3, which are far better than the emission standards of natural gas generator sets of 35 mg/m3 of sulfur dioxide, nitrogen oxides 50 mg/m3, and soot 5 mg/m3. After the ultra-low emission of electrolytic aluminum, the particulate matter is 2 mg/m3 and sulfur dioxide is 10 mg/m3, far better than the 20 mg/m3 particulate matter and 200 mg/m3 required by the "Aluminum Industry Pollutant Emission Standard" The requirements of the company are in the leading international level.
