We have built 5 solar photovoltaic power stations, with a power generation capacity of 5.91 million kWh in 2021. In the future, we plan to build 3 additional solar PV power plants in 2022, with an estimated electricity generation of 13 million kWh; by 2025, we expect to build more than 10 solar PV power plants. In addition, we are also acquiring green power through purchasing green power certificates. In 2021, the cumulative green power usage totaled 15.91 million kWh.
All production bases have been covered with waste gas treatment facilities, and some of the subsidiaries have launched the waste gas online monitoring system to monitor waste gas factors in real time and ensure that the treated waste gas meets relevant standards.
YUTO has built 15 wastewater treatment stations at our production bases nationwide, and is committed to reducing the waste water emission and reusing the water, and ensuring that all treated wastewater meets the discharge requirements at the domestic and regional levels where we have the business operations.
We have continued to promote the zero waste to landfill project in order to achieve waste reduction, harmless waste treatment and resource reusing. Currently, there are 3 factories of YUTO that have passed the Platinum Zero Waste to Landfill Certification.
