  • Pollution Prevention
  • ASE's facilities strive to reinforce and improve pollution prevention measures for wastewater (please refer to Wastewater Management), solid waste, air pollution and noise. We implemented ISO 14001 Environmental Management in all of our facilities to minimize environmental impact through pollution prevention mechanisms, and "Plan-Do-Check- Act" to promote continuous improvement.

    Waste Management

    In 2016, 54,464 metric tons of waste was generated, out of which 49% was industrial hazardous waste. Of all the waste generated*, 70% was recycled (26% hazardous waste and 44% general waste). Waste treated through landfill, incineration, solidifying and others was 16,221 metric tons, a 12% reduction compared to 18,338 metric tons in 2015.

    For waste reduction, we have adopted an eco-design approach to reduce the amount of waste we produce. For example, out lightweight IC design reduces the amount of plastic waste. We have also continued to reduce pollution and initiate waste recycling to reduce the volume of sludge by enhancing sludge dehydration efficiency and activation rate, reducing and improving process source, recycling waste liquids from electro-plating machines, and discouraging the use of disposable cutlery.

    ASE continues to engage in industry-academia collaboration with well-known universities to research and develop the technologies to treat special waste liquids, such as high concentration of waste liquids containing boron, hydrogen peroxide and high COD.

    * This data covers all ATM and EMS facilities.

    Green Packaging Materials
    ASE uses packaging materials made from recyclable materials. In 2016, 3,432 metric tons of packaging boxes, 1,001 metric tons of pallets, 710 metric tons of wafer boxes and 890 metric tons of other packaging materials were recycled. We have also reduced the consumption of natural resources through the process of sorting and recycling packaging materials.

    Partnering with Customers and Suppliers to Reduce Environmental Impact
    In 2016, ASE Kaohsiung and Chungli worked with the customers to recycle over 0.24 million wafer boxes. We also co-operated with chemical agent suppliers to recycle and extend the service life of empty barrels for re-fill and reuse. In 2016, ASE Kaohsiung and Chungli recycled over 10 thousand empty barrels.

    Gas Emissions Control

    We adopt ozone scrubbers to treat volatile organic compounds (VOCs) emissions, the main source of air pollutants generated from our plant processes. To reduce the amount of wastewater produced during the ozone scrubbing process, we adopted high-efficiency ozone scrubbers to ensure that the concentration of the VOC treated at our facilities is far lower than the regulatory limits. For organic exhaust, the pollutants are first concentrated by Zeolite rotor, then imported into Regenerative Thermal Oxidizer (RTO) and emitted after incineration.

    In 2016, the amounts of air pollutants generated by ASE are listed below. We generated 269 metric tons of VOCs, a decrease of 19% as compared with 331 metric tons in 2015. The decrease was a reflection of the actual amount of VOC emissions through the raw material testing by a fair third-party agency. To reduce air pollutants emissions, our future air pollutant management program will focus on the following actions:

    • Improve Raw Material Usage Control: Adopt material control table to ensure our material usage is compliant with regulatory requirements

    • High-VOC material usage reduction and possible substitution of low-pollutant materials

    • Conduct annual efficiency testing on air pollution control equipment, and improve low-efficiency equipment to enhance the efficiency of air pollution control equipment

    • Introduction high efficiency processing equipment (e.g. Regenerative Thermal Oxidizer (RTO) or activated carbon processing system) to our existing and new facilities

    • Through the resource integration at campus and enterprise, conduct emission shunt and reduction at production source and optimization of chemical agent and water discharge operation parameters of prevention equipment at end of production, to increase pollutant removal efficiency

    Volatile organic compounds 161 250 330 269
    Ozone depleting substance 0.03 0.02 0.04 0.02

    Noise Control

    ASE conducts the monitoring, reporting and management of noise surrounding facilities. In 2016, there were no noise records exceeding regulatory control. We shall continue to mitigate noise emitted from our facilities, and engage in industry-academia collaborations to develop noise diffusion model analysis, assess equipment noise, reduce noise at facilities and working environment, and improve the quality of local residents' living environment and employees' working environment.
