The main sources of waste gas for Taiwan Mask Group are the chemicals used in the manufacturing process and the waste gas emitted by transportation vehicles. In order to ensure that the waste gas generated by the equipment used in the factory and the product manufacturing process complies with the current environmental protection regulations after treatment, strict waste gas emission monitoring is carried out.

Manage and Respond

  • ■ Process Exhaust Gas Control: For exhaust gases generated from the use of chemicals in process operations, a closed exhaust gas collection system is used to direct the exhaust gases from each operation to air pollution control equipment. After treatment, the gases are released into the atmosphere. A qualified environmental testing agency is commissioned annually to sample and test the emission outlets of the air pollution control equipment. Regular testing of volatile organic compounds (VOCs) ensures compliance with permit requirements. ■ Transportation Vehicle Exhaust Gas Control: Exhaust gases emitted from transportation vehicles are regularly maintained and tested by a qualified testing agency to ensure that emissions comply with regulations and the emission standards of the science park. Note 1: Miracle Technology Co., Ltd. and Xsense Technology Corp, INC. are not listed as air pollution control products by the Ministry of Environmental Protection.
  • Regular maintenance of the scrubbing tower, including replacing Raschig rings and nozzles, ensures treatment efficiency, improves equipment stability, and guarantees that exhaust emissions meet regulatory requirements. The system is also connected to monitor key parameters in real time, and regular testing results show that the concentrations of all pollutants are well below regulatory limits. Furthermore, improvements to the scrubbing tower's aging piping and dampers enhance the stability of the air pollution control system, resulting in emissions and removal efficiency meeting environmental regulations for the past two years.
  • All of Taiwan Mask Group's operating sites emit no ozone-depleting substances (ODS), and in 2024, there were no incidents of exceeding emission standards or causing environmental or social harm. To reduce pollutant emissions, Taiwan Mask Corporation will replace aging fans and control panels in its scrubbing towers, add fans and automatic trip switching functions, and install an RCO catalytic regeneration oxidation furnace system to treat VOCs, increasing treatment efficiency by 87% in 2024.
Water resource management

Water resource management

Monthly water usage is recorded in an "Annual Water Management Sheet" to facilitate monitoring of water usage in each factory area, timely detection of water supply equipment malfunctions, and rapid problem-solving to avoid unnecessary water waste and reduce operational water and land pollution. Taiwan Mask Group sources 100% of its water from third-party sources (tap water). Water is primarily used for production and employee living, with a total water intake of 347,280 tons in 2024. In 2024, due to the addition of many cleaning machines, water consumption increased by 96,696 tons compared to 2023, while wastewater discharge increased by 73,516 tons compared to 2023.

Manage and Respond

  • By adopting the best and most feasible pollution prevention and control technologies, establishing water flow records for each wet scrubbing machine, and analyzing the wastewater quality of each wet scrubbing machine under different process conditions, we can help identify wastewater that can be recycled and reused. The recycled and reused wastewater is then treated and returned to the process or supplied to cooling towers and scrubbing towers to improve resource utilization efficiency and reduce the amount of tap water used for makeup.
  • In terms of water resource risk management, Taiwan Mask Group uses the World Resources Institute (WRI) water risk assessment tool to evaluate the water resource pressure and water risk of each plant area. KEMET uses water from Baoshan Reservoir, while Milo and AgroScience use water from Yongheshan Reservoir. The assessment results show that all of them are classified as low to medium risk and are not listed as high-risk water resource areas, with no significant impact on water use.
  • To mitigate potential water resource risks, Taiwan Mask Group actively upgrades its water recycling equipment to improve water reuse efficiency. Furthermore, it has developed a water shortage contingency plan, collaborating with government agencies to regulate water resources and achieve government-set water conservation targets. It also works with the Science Park Administration or the Water Resources Agency to coordinate water usage, ensuring stable operations even during dry seasons when water shortages occur.
  • Continuously refining water-saving technologies to increase water conservation, the company is promoting condensate recovery projects and cleaning machine water recycling programs to increase water reuse opportunities and reduce water intake. The cleaning machine water recycling program is planned to be expanded in 2025, and the water recycling system will continue to be used. The company is also improving the operational efficiency of wastewater treatment facilities, aiming to achieve process water savings of 1,145 tons by 2024. In the future, Taiwan Mask Group will continue to promote water-saving projects and refine related recycling measures to reduce water consumption and environmental impact.
  • Taiwan Mask Corporation employs a secondary protection system to prevent wastewater overflow and environmental pollution in the event of system malfunctions or tank damage. In addition to internal water quality testing, offline sampling and analysis are also outsourced to ensure strict monitoring of the aquatic environment. Currently, the plant collects process chemicals separately and treats wastewater according to its characteristics, improving the efficiency of dedicated wastewater treatment. The treated wastewater is then discharged into the Hsinchu Science Park Wastewater Treatment Plant. Taiwan Mask Group has established an environmental management system based on ISO 14001 for water resource management, monitoring water usage at each plant. Its effluent management not only exceeds regulatory standards but also continuously monitors effluent quality online. To ensure effluent quality, regular water quality testing is conducted every six months, including testing for biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, suspended solids (SS), CN-, Cr+6, Cd, Pb, Cu, Zn, Ni, Cr, Hg, As, water temperature, ammonia nitrogen, nitrate nitrogen, anionic surfactants, boron, and fluoride. Water quality test results for the past three years show that all levels are below legal standards. Note: Miracle Technology Co., Ltd. does not manufacture products in this area and therefore does not require water quality testing.
