Environmental Sustainability Actions and Effectiveness in 2024
  • Successfully passed ISO 14001 Environmental Management System certification and continued to employ the best feasible air pollution emission management technologies (SDG 3.9 achieved)
  • Continuing our commitment to technological improvements and equipment investments, PSMC has increased water recovery rates and process water efficiency. We became the first semiconductor company in the Hsinchu Science Park to commit to a process water recovery rate of 85% or better. In 2024, the water recovery rates across all fabs reached 88% (SDG 6.4 achieved)
  • Since the official production launch of Fab P5 in 2024, it has utilized 600 cubic meters of reclaimed water per day (SDG 6.b achieved)
  • PSMC participated in 40 water-saving guidance projects for suppliers, achieving a cumulative water-saving result of 1.3862 million metric tons. In 2024, the suppliers receiving guidance are expected to save 382,000 metric tons of water annually. Additionally, a follow-up on the 10 suppliers that participated in the 2023 water-saving guidance program showed a water-saving volume of c. 341,000 metric tons, for an achievement rate of 83.7% (SDG 6.5 achieved)
  • The manufacturing process wastewater is pre-treated in the wastewater treatment plant, then discharged to the wastewater treatment plant in the park for subsequent treatment and discharge, and divide the discharge from the manufacturing process into a total of 20 different drainage water systems, such as recyclable and non-recyclable, according to their different characteristics, such as type, concentration, and conductivity. In addition to increasing the recovery rate of water, some waste acids and organic waste liquids have economic value for recycling, so separate diversion will not only reduce the amount of treatment dosage in wastewater plants, but also reduce the difficulty and environmental burden of waste treatment at the back end (SDG 6.3, SDG 6.4 achieved)
  • The implement of the ISO 50001 energy management system to analyze the efficiency of energy consumption through energy management, seeks the effective use of energy (SDG 7.3 achieved)
  • Regarding the management philosophy of introducing waste management into the lifecycle, we will continue to promote the following objectives: (1) source reduction, (2) end point waste reduction, (3) enhancing the value of waste reuse, and (4) proper disposal and the tracking of waste flow (SDG 11.6 achieved)
  • The waste generated is classified by type and disposal method, and is cleaned up and reused by qualified waste vendors; waste cleaning is strictly required to comply with waste cleaning laws and international regulations, and waste generated on site is attended to at all times and evaluated for the appropriateness in the waste cleaning market (SDG 12.5 achieved)
  • To understand the environmental impacts of semiconductor foundry products across raw material acquisition and manufacturing stages, identify environmental impact hotspots at each stage, facilitate performance improvement strategies, and communicate with customers, a comprehensive product lifecycle assessment mechanism was implemented in 2023 (SDG 12.2 achieved)
  • The IGBT products launched by PSMC are produced on 0.4μm 8-inch wafers, which are applied in electric vehicles and variable-frequency home appliances. They are essential components in energy-saving products. In 2024, they contributed to reducing greenhouse gas emissions by 31.22 billion kg CO2e collectively for customers (SDG 9.4 achieved)
  • To ensure the ability to resume normal operations within the shortest possible time in the event of a major accident or crisis, PSMC has established business continuity plans for specific crisis events such as prolonged power supply interruptions or disruptions in raw material supply (SDG 13.1 achieved)
