Our water consumption is mainly for plant operation, and we set a specific target of 2% water saving for each production site every year. Domestic wastewater is recycled by RO for irrigation and toilet cleaning, and about 2,300 tons of wastewater is recycled every month for secondary use and watered for plants in the morning to reduce temperature evaporation. The fish tank uses a recirculating water supply. In order to minimize the waste of water resources, the staff is instructed to develop good water habits and turn off the faucet after using water.
