Insights into United Microelectronics's Waste Treatment Practices
In 2023, United Microelectronics generated a total of 64,307 metric tonnes of waste.
Of this amount, 91.41% of United Microelectronics's total waste generated was recovered through methods such as recycling, reuse, or composting, while 8.59% was disposed of through landfilling, incineration, or combustion.
United Microelectronics's Waste Recovery Rate
How much of United Microelectronics's waste is recycled or recovered?
In 2023, United Microelectronics reported a total waste generation of 64,307 metric tonnes, of which 91.41% was recovered through recycling, reuse, or composting. This high recovery rate suggests that United Microelectronics has implemented strong circular economy practices and actively prioritizes sustainable waste management.
Has United Microelectronics reduced its environmental waste footprint over time?
Since 2020, United Microelectronics's total waste generation increased by 99.37%, including a 71.88% increase in 2023, indicating a persistent upward trend that may reflect scaling operations, inefficiencies in resource use, or a lack of effective waste minimization practices.
Over the same period, United Microelectronics's waste recovery rate increased by 7.4%, including a 3.81% rise in 2023, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.
Overall, United Microelectronics has seen a consistent rise in waste generation both over the long term and in the year 2023. However, the company has also steadily improved its waste recovery performance, suggesting that it is actively working to offset the environmental consequences of increased production through enhanced circularity efforts.

How United Microelectronics reduced the environmental impact of its waste?
Since 2020, United Microelectronics's total waste generation increased by 99.37%, including a 71.88% rise in 2023, reflecting a persistent upward trend that could be linked to operational growth, inefficient material use, or limited investment in waste prevention systems.
Over the same period, United Microelectronics reduced the hazardousness of its waste by 12.57%, with a further 8.62% decline in 2023, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.
Overall, United Microelectronics is generating more waste but has significantly reduced the share of hazardous materials, suggesting a partial decoupling of volume and toxicity that could reflect more responsible inputs or enhanced treatment.
How does United Microelectronics treat its hazardous waste?
In 2023, United Microelectronics reported that 39,496 metric tonnes of its total waste output were classified as hazardous. This represents 61.42% of its overall waste generation.
The company treated this hazardous waste using a combination of methods. A majority (92.76%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that United Microelectronics has established processes to reduce the environmental burden of its most harmful waste streams.
