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 2023 is NT$4.11 billion, including NT$2.89 billion in direct environmental load reduction investment, NT$61.9 million in indirect environmental load reduction investment, NT$18.2 million in environmental investment to combat climate change, and environmental protection operating expenses. 1.15 billion yuan, the 2023 energy conservation and carbon reduction project will achieve an annual carbon reduction of approximately 599,698 tons. Important investment in energy conservation projects include:

(1) Equipment efficiency improvement:
Using permanent magnet synchronous and energy-efficient motors to replace old and inefficient motors can achieve energy savings of more than 10% and reduce carbon emissions by approximately 1,049 metric tons annually.

(2) System energy-saving adjustment:
The line body is optimized for water and power saving. By shortening the water and power saving time setting of the equipment, the waste of standby water and power is reduced, and the annual carbon reduction is approximately 1,438 metric tons.

(3) Heat energy recovery and reuse:
Through water source heat pumps, the heat dissipation of air compressors and ice machines is recovered to replace the steam heating required for water inlet and air conditioning box reheating. Through heat energy recovery, the use of boiler natural gas is reduced and carbon emissions are reduced. The annual carbon reduction is approximately 4,608 metric tons.

(4) Self-installed solar power generation:
• The solar energy installation capacity of Huaian No. 1 Park is 1.85 MW (spontaneous and self-consumption)
• Huaian Second Park solar energy installation of 1.96 MW (spontaneous and self-consumption)
• Shenzhen Park’s solar installation capacity is 0.57 MW (spontaneous and self-consumption)
Carbon reduction reaches 2,867 metric tons/year

(5) External purchasing green power:
External purchase green electricity and use green electricity to reduce greenhouse gas emissions. Carbon reduction is 555,264 metric tons/year.

Manufacturing Using Recyclable Metals

The key raw materials used by Zhen Ding include gold, palladium, and tin, involving potassium gold cyanide, palladium salt/palladium solution, copper powder/copper balls/copper foil, solder paste/tin balls, and copper foil contained in FCCL and CCL. Zhen Ding has been working with suppliers and customers to promote the use of recycled metals. The introduction of recycled potassium gold cyanide has been tested in the first half of 2021 and has already been introduced into the production of some of our business units, with the annual amount of recycled potassium gold cyanide reaching 7% of the potassium gold cyanide usage. More business units and more products are expected to introduce the use of recycled potassium gold cyanide in 2022. In addition, the amount of copper recycled in copper powder/balls is still under investigation, but in the copper clad laminate (CCL) segment, we have already requested suppliers to use copper foil made from recycled copper, and some upstream copper foil manufacturers of CCL already use more than 90% recycled copper. We are currently testing the use of CCL made of 100% recycled copper and expect to partially introduce it by 2022.

Zhen Ding strives to promote the circular economy and has gradually introduced recycled metals for production in 2021, including the following:

1. The total amount of recycled gold used in production is about 442 kg (about 35% of the total gold usage), of which the gold reused (reuse during the production process) is about 83 kg (about 6.6% of the total gold usage)

2. The total amount of recycled copper used in production is about 6,110 tons (about 70% of the total copper usage). The recycled copper provided by suppliers (i.e. using recycled copper to make copper foil), is approximately 810 tons; moving forward, it is planned to reproduce copper carbonate from waste liquid to provide raw materials for the use of phosphorus copper balls, and the total amount of recycled copper can be used in production is approximately 918 tons.

3. The total amount of recycled palladium used in production is about 51 kg (about 21% of the total palladium usage)

Source Reduction and Recycling

Best Case : Copper-containing Micro-etching Circulation

The copper-containing micro-etching waste is processed by the in-plant recycling system to recover copper metal and recycle micro-etching solution. The copper metal can be recycled, and the micro-etching solution is reused in the manufacturing process to achieve the effect of reducing both hazardous waste and raw materials.
