In terms of environmental protection, we adhere to green and low-carbon development, significantly reduce energy consumption, and minimize the generation of pollutants. We attach great importance to protecting land and ecological environment, and improve management measures for pollutants such as exhaust gas, wastewater, noise, and waste. In addition, we attach great importance to the utilization of reusable resources. For example, we reuse production water as cooling water for alumina production. During the calcination process of alumina, the residual heat energy recovered from the calcination furnace is used for heating equipment cleaning water and other purposes.
