Pollution Prevention
Air Pollution Prevention
The main sources of air pollution for the Wang-Tien Factory area are the air pollutants generated from the natural gas used by the boiler and incineration treatment facility, and the Volatile Organic Compounds (VOCs) generated during manufacturing process. The air pollutants preventive measures are by injecting adsorption system, condenser, cyclone dust collector, low NOx burner, washing tower to the air prevention system facility. These have greatly reduced the particulates, SOx, NOx, and air pollution sources.
The control of VOCs is through the operation of Regenerative Thermal Oxidizer (RTO) equipment. The control facility's removal efficiency of VOCs was tested by a testing unit approved by the Ministry of Environment in October and November 2023, reaching a removal efficiency of more than 95%.
Due to the Company's M16 blending process as the major source of VOCs, after washing and the use of activated carbon adsorption, the 2023 air pollution monitoring test report shows that the VOCs emissions from this manufacturing process is not high (emissions of 1.20018 kg-voc for every metric ton of product produced). However, this manufacturing process cannot achieve the testing method using mass-energy balance to calculate pollution quantity and is unable to know exactly the raw materials contents and formula, there is situation of the VOCs for this manufacturing process is higher than the actual production. In 2023, M16 produced 848.87 metric tons of product. The process has been verified by the Environmental Protection Bureau as in compliance with environmental standards for smoke and perimeter odor pollutant testing only. The air pollution of Zhangbin Plant mainly comes from the VOCs generated by the melting and molding of plastics. The 2023 air pollution testing report showed that the emission of VOCs from this process was not high (about 1.77996 kg-voc for every metric ton of products produced), and no air pollution control fees were incurred.

2023 Air Pollution Control Measures
- Maintaining the normal operations of two low temperature plasma ion air purification equipment
- Set up 2 activated carbon gas adsorption equipment for the waste pond to remove the VOCs of the adjustment pond unit of the wastewater pond; The 2 low-temperature plasma ion air purification equipment can strengthen the capacity in the removal of unpleasant odor substances. Efforts are in place to maintain the removal rate of the VOCs at over 95%
- Maintaining the operations of the VOCs activated carbon gas adsorption equipment, and plasma ion air purification equipment
- When the gas emissions release towards the end of the preventative equipment, the activated carbon gas adsorption equipment, and plasma ion air purification equipment will capture the VOCs and the unpleasant odor to achieve the effects of purified air.
- 5 self-made UV photolysis machines were built in 2023. 4 are in use and the other one is used as a backup machine. After FID detection and odor detector testing, the removal rate of VOCs can reach more than 50%

Waste Management
The Company makes further considerations for the management of wastes on its circular reuse. Aside from the appropriate sorting, collecting and handling of the wastes based on internal control mechanism according to related regulations, we pursue to optimize the resource usage rate through reduction, recycling and reuse. Do our best to turn waste into resource in order to lower the burden of waste on the environment. The waste of the Wang-Tien Factory area is divided into self-handling and outsource handling. Self-handling is using the incinerator facility within the factory mainly for treating the sludge from the wastewater pond; Outsource handling is commissioning cleaning services business and recycling businesses. The wastes generated by Zhangbin Plant are all general domestic wastes, and there are no wastes generated from manufacturingprocesses.
To ensure that the appointed clearance operators possess the qualifications requirements by the government, the Company will conduct a review of the operators beforehand through the published information (including approval license, company operations overview, code for clearance/waste handling, and the expiration date of the approval license and so on basic information) by the EPA. After confirmation of their qualifications and suitability, will sign MOU and contract with the vendor for the
appointment. In addition, Wang-Tien Factory area also outsources the testing of heavy metal residues, poisonous substance residues, toxicological characteristic dissolution procedures (TCLP), pH value and other information in hazardous industrial waste every six months in accordance with the “Hazardous Industrial Waste Testing and Record Management Measures” to ensure that hazardous industrial waste does not have a significant impact on the environment and human health.
