Waste Management

ASEH adopts source reduction measures and prioritizes the use of eco-friendly materials to minimize waste generation and reduce environmental pollution. We require all facilities to complete ISO14001 certification, and collect and track each facility’s environmental-related data from the environmental management platform on a quarterly basis. Facilities that have not achieved the targets will need to propose improvement plans to reduce their waste output and increase their recycling rate. In 2024, a total of 76,857 tons of waste was generated; a positive progress towards our goal of zero landfill. To manage the compliance of waste disposal contractors, each facility conducts regular annual audits of their contractors through online, paper-based, and on-site inspections (a total of 268 sessions). Additionally, unannounced audits are carried out to prevent environmental pollution incidents. To improve waste resource utilization, we have adopted the circularity model with a goal of 90% recycling rate for non-hazardous waste. In 2024, the hazardous waste intensity (hazardous waste generated per revenue) decreased by 53% compared with 2015, resulting in a 93% general and hazardous waste recycling rate which is a 2% increase from the previous year. We also provided employees with education and training on environmental issues, totaling approximately 176.47 training hours for 43,881 participants. This training initiative effectively boosts employees’ awareness and understanding of waste reduction, enabling the company to integrate the ethos of waste reduction into its operations and achieving its ultimate goal of zero waste to landfill.

At our facilities, local government regulations mandate a close to zero (<0.1%) landfill for hazardous waste. There still remains approximately 1% of general waste that must be disposed of in landfills, which is 1% less than last year.
ASE Kaohsiung K21 has achieved UL 2799 Zero Waste to Landfill Platinum Level validation. Additionally, USI Shanghai-Shengxia and Zhangjiang Facilities have each obtained UL 2799 Zero Waste to Landfill Gold Level validation.
To ensure that waste removal is environmentally friendly and conducted responsibly, we have commissioned qualified local vendors to recycle and process 100% of the generated waste within the border. AI-based automatic monitoring of waste collection vehicle movements is being gradually implemented to ensure that waste handling does not impact the environment.

Striving Toward a Circular Economy

The concept of the circular economy has garnered greater global attention in recent years as concerns with the continuous depletion of natural resources grow. To optimize the use of Earth’s resources, the application of relevant expertise and the weighing of economic benefits are prime factors in implementing a circular economy. At ASEH, we are putting the circular economy in action by adopting five key approaches direct recycling, reuse, off-site regeneration, renewable materials and supply and leasing. We collaborate actively with suppliers and business partners across the industry chain to build a semiconductor circular economy through practical actions such as redesign, value-added circularity, recycling and recovery, shared economy, circular agriculture, and industrial symbiosis. In addition, we have formed alliances with organizations in our industry and from other sectors to examine the life cycles of resources and identify areas where resources can be reduced, recycled, and reused to prolong their lifespan, and maximize resource efficiency.
