Nan Ya PCB Corporation

(1) Air Pollution Control
The main source of air pollutants generated in Nan Ya PCB’s plants came from the use of neutral, acidic, alkaline, and organic chemical compounds with volatility during production processes. Thus, in addition to the separation of those chemical compounds at the source of exhaust gas pipes, specific equipment such as scrubbers, bag filters, and activated carbon towers has been installed to handle each type of waste gas. To enhance the effectiveness of VOC processes and eliminate odors around the plants, Nan Ya PCB purchased a UV-C reactor treatment system and installed a pH monitoring system on the scrubber to increase the efficiency of exhaust gas reduction. The Company also ensures the equipments to be maintained regularly so that they can effectively function to control pollution. If new equipment is installed or an existing one is upgraded, Nan Ya PCB has companies, which certified by Environmental Protection Administration, to examine air pollutants in their stacks to make sure air pollution control is effective. Historical results show Nan Ya PCB’s air pollutant emissions are much lower than national emission standards.

(2) Waste Water Processing
Nan Ya PCB has taken the characteristics of wastewater and the stability and accessibility of wastewater treatments into account when designing its wastewater treatment procedures and facilities. Also, in place is a comprehensive plan of adequate pipes allocation to classify the source of wastewater to strengthen wastewater control, recycling, and reuse. Wastewater is stringently and immediately categorized when it is produced by equipments and machineries. The water is collected through distribution channels to specific water treatment facilities. The Company tests effluents daily to ensure that the quality of treated water is far lower than national standards. Each one of the Company’s manufacturing plants and the surrounding areas are located in the B type industrial land, which was planned by the government and exclusively for industrial use, and none of plants’ locations is in ecological reserves. Nan Ya PCB is going to continue to lower waste water emissions and boost the effect of wastewater processing through the improvements in manufacturing processes and equipment to mitigate its impact on the environment.

(3) Water Recycling
Production activities consumed the most water in Nan Ya PCB. The main water sources include tap water, recycled water, purchased industrial water etc. Since Nan Ya PCB does not use groundwater, it has strived to lower water consumption by reducing water used during production and recycling the water used in cleaning during production process. The Company has also invested heavily in an effluent recycling and treatment system, and has reduced wastewater in all of its plants; neutral or alkaline recycled water is reused as a source for water consumption for pollution control. Purified recycled water is directly reused by plants and stored at pure water storage reservoirs to reduce water recharge. Water-saving devices have also been installed on the faucets in offices to reduce office water consumption and cultivate water-saving culture.

(4) Reduction of Waste Materials
Nan Ya PCB has established multiple waste collection and recycling points within its plants to reduce wastes and make the best use of its resources and materials. The Company also continuously improves its production processes and operations. First, we reduce the waste spawned at beginning of the production. Then, we consider reuse, and eventually wastes are categorized and reused to make resources recyclable.
The results of waste reduction have met the expectation. In the future, we will continue to implement various waste reduction and resource recycling measures to reduce the amount of waste. All of industrial wastes from the Company are contracted to qualified domestic waste management companies and handled by qualified waste treatment plants.

(5) Greenhouse Gas Emissions Reduction
Global warming and changes in climate have become a key issue for sustainable development. With Increases in greenhouse gases and temperature around the world, the change in global climate has become abnormal and triggered unpredictable impacts on the environment. Nan Ya PCB has recognized the importance of these issues and has conducted comprehensive examinations and evaluation of its greenhouse gas emissions since 2005 in accordance with the principles of ISO 14064-1 to reduce its greenhouse gas emissions and achieve sustainable development. As an electronics ODM service provider, over 98% of Nan Ya PCB’s greenhouse gas emissions were generated by the indirect discharge of purchased electricity. Thus, reducing electricity consumption is the most effective way to cut greenhouse gas emissions. The Company also adopted the Plan-Do-Check-Act management model to improve its facilities, reduce its emissions continuously, and increase competitiveness.
Through ongoing energy saving actions, our unit greenhouse gas emission (ton CO2e/NT$M) has achieved the target. In the future, we will continue to strive for promoting energy-saving improvement measures to strengthen energy efficiency, in order to reduce greenhouse gas emission.

(6) Nan Ya PCB Sustainable Achievement:
We have strived to lower energy cost and increase energy usage efficiency and set environmental management targets annually. Through a proposing and compensating system, we promoted every department to review and improve its own energy usage efficiency. Also we have an internal energy management sector to handle such tasks, and it convenes the energy management conference every month to implement the Company’s policies and perform the internal auditing for energy saving projects.
