Energy Management

• The energy used by EGST includes electricity, gasoline, diesel, etc. The information for each factory is as follows :

• Taipei Head Office

• Hsinchu Factory

• Xinying Factory

• Kaohsiung Factory

• Total Energy Consumption of Each Factory

• Energy Saving and Carbon Reduction

• To reduce the impact of energy use on global warming, EGST continues to replace high-power halogen bulbs with energy-saving LED bulbs and install automatic control systems. In addition, we occasionally advocate environmental protection activities such as energy conservation and carbon reduction, recycling of waste paper, and use of environmentally friendly tableware. The management method of engineering and administrative improvement is used to save energy in order to achieve the goal of reducing GHG emissions.
• EGST promotes and implements various energy saving and carbon reduction measures through meetings and announcements, and formulates energy policies to reduce energy use and implement environmental protection. The energy policies and measures are as follows :

• Energy Policy

• Energy Saving Target

• According to the "Regulations for Energy Saving Target Stipulation and Plan Execution by Energy Users" announced by the Ministry of Economic Affairs, legal and natural persons with contracted electricity capacity exceeding 800 kW should set energy-saving goals and implementation plans, and the average annual electricity saving rate from 2015 to 2024 should reach more than 1%, Therefore, EGST sets an annual energy-saving target of 1% of electricity consumption.

• EGST adheres to the concept of energy saving and sustainable operation and has long been concerned about energy issues. In 2022, it replaced the lamps that have reached their service life, and installed lighting timing devices and automatic lighting switches, saving a total of 642.25 GJ of electricity.
• In addition, according to the annual electricity saving target of 1%, and phasing out high-energy-consuming process equipment in 2022, it is estimated that a total of 1,447 GJ of externally purchased electricity will be saved in 2025.

• Energy-Saving Design

• Considering the environmental protection issues arising from the production and use of cement in construction, and the difficulty of reusing RC reinforced concrete buildings during demolition and reconstruction, the use of green building steel structures has gradually become a trend in architectural development. All countries in the world are constantly developing steel as the basic raw material for buildings. In the past 20 years, steel structures have gradually become the mainstream of important green buildings and bridges.
• In 2005, CPAMI added a special chapter for green buildings in the Construction Law, which requires that buildings with more than 11 floors must meet the standards of green construction in order to obtain a construction license. This law is used to regulate the development of buildings towards lightweight structures, and steel structures are the easiest construction form to achieve this requirement.
• Domestic building materials mostly use traditional reinforced concrete, but the production of cement will generate a lot of carbon dioxide, while developed countries use relatively low-carbon steel structures, so carbon dioxide emissions are relatively low. In general, the CO2 emissions and energy consumption of steel structures are much lower than reinforced concrete, so steel structures are considered to be the material with the least impact on the environment. In addition, the recyclability and manufacturability of steel has led it to be called a green construction material internationally. Therefore, steel structures have become the mainstream of civil buildings in developed countries.

Water Use and Water Conservation

• Water Resource Management

• Due to the extreme climate, there is a risk of water shortages, and because water resources are not inexhaustible and not always available for use, EGST proposes various measures to implement water resources management, such as :

• Taipei Head Office

• Taipei Head Office is not a production unit, and the source of water demand is domestic water for office employees. With the spread of the pandemic slowing down in 2022, fewer employees were working from home and thus water consumption increased compared to 2021.

• Hsinchu Factory

• The Hsinchu factory is located in Hukou Township, Hsinchu County. Water stress in the area where the plant is located is "low-medium risk (1-2)" according to the World Resources Institute's "Water Aqueduct". The main source of domestic water is tap water, and the discharged sewage is processed by the sewer operation center of the industrial area. Monthly water quality testing meets discharge water standards. There is a backup groundwater well with legal water rights in the plant, which can be used in times of drought.

• Xinying Factory

• The water source of the Xinying Factory is tap water, and groundwater is not used. The water is mainly domestic water, and the production process produces less industrial wastewater. The generated domestic sewage is treated by sewage treatment facilities and then discharged into public sewage sewers and sewage treatment plants in the industrial zone.

• Kaohsiung Factory

• The water source of Kaohsiung Factory is tap water, which is divided into domestic water and container cleaning water. Sewage treatment facilities and sewage permits are installed on site, and operational sewage is discharged through special pipelines. The sewage from the operation is discharged through the factory's treatment system to meet the discharge standards, and finally discharged to the sewage treatment plant in the Linhai Industrial Zone. The factory's sewage treatment process is in compliance with environmental regulations and has no impact on the environment. There was no leakage in 2022. The chemical oxygen demand (COD), biochemical oxygen demand (BOD) and suspended solids (S.S) detected by the discharge water value all meet the discharge standards.
