Promote Low-carbon and High-efficiency Production
In accordance with the initiative to control global warming by 1.5°C, combined with the requirements of local governments and our company's sustainable development strategy, Zhen Ding has formulated climate change management strategies and green development goals, and actively promoted low-carbon, high-efficiency and cleaner production activities.
The total investment in 2022 is NTD 370 million, including an investment of NTD 304 million in direct environmental mitigation, an investment of NTD 60.61 million in indirect environmental mitigation, and an environmental investment of NTD 1.52 million in response to climate change. Energy conservation and carbon reduction projects in 2022 have achieved an annual carbon reduction of approximately 25,310 tons. The key investments and energy-saving projects include:
(1) Equipment efficiency improvement: magnetic levitation chillers
Our Shenzhen site has introduced magnetic levitation chillers, which can save more than 30% of energy compared to traditional centrifugal units. By replacing traditional chillers, the electricity usage reduces by 1,820,000kWh/yr.
(2) Energy management: self-built solar power generation on-site
Solar power generation is built on the roof of our buildings, with a construction area of 15,000 square meters, an annual power generation of 3,952 megawatt hours (MWh), and a carbon reduction of approximately 2,780 tons.
(3) Heat recovery and reuse: water source heat pump
Our Qinhuangdao site uses water source heat pumps to recover the waste heat emitted when air compressors, chillers and other equipment are operating to replace the steam needed to heat up water and air, reducing the use of natural gas in boilers and reducing carbon emissions. The use of natural gas is reduced by approximately 2.29 million cubic meters/yr.
