In 2024, Taiwan Semiconductor Manufacturing conducted an environmental assessment and disclosed corporate waste management data in accordance with recognized sustainability reporting standards.The company provided a breakdown of its waste by type (hazardous vs non-hazardous) and treatment method (recovery vs disposal), enabling greater transparency into its waste handling and environmental practices.
| Metric (tonnes) | 2024 | 2023 | 2022 | 2021-2019 |
|---|---|---|---|---|
Total Waste Generated | 789,208a | 656,841a | 744,019a | |
Total Waste Recovered | 1,067,782a | 911,856.96a | 975,980.16a | |
Total Hazardous Waste Generated | 445,152a | 371,236a | 401,215a | |
Non-Hazardous Waste Disposed | 30,675a | N/A | N/A |

In 2024, Taiwan Semiconductor Manufacturing generated a total of 789,208metric tonnes of waste.a
Of this amount, 135.3% of Taiwan Semiconductor Manufacturing's total waste generated was recovered through methods such as recycling, reuse, or composting, while 4.64% was disposed of through landfilling, incineration, or combustion.a
In 2024, Taiwan Semiconductor Manufacturing reported a total waste generation of 789,208 metric tonnes, of which 135.3% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Taiwan Semiconductor Manufacturing has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2020, Taiwan Semiconductor Manufacturing's total waste generation increased by 37.08%, including a 20.15%increase in 2024, indicating a persistent upward trend that may reflect scaling operations, inefficiencies in resource use, or a lack of effective waste minimization practices.a
Over the same period, Taiwan Semiconductor Manufacturing's waste recovery rate increased by 11.92%, but declined by 2.54% in 2024, potentially signaling volatility in waste treatment processes or shifting priorities in waste management.a
Overall, Taiwan Semiconductor Manufacturing’s waste generation and recovery data show a mixed and inconsistent trend. A deeper analysis of the company's activities, industry benchmarks, and operational changes is needed to assess its sustainability performance more precisely.
In 2024, Taiwan Semiconductor Manufacturing generated a total of 789,208 metric tonnes of waste.a
Of this amount, 56.4% of Taiwan Semiconductor Manufacturing's total waste generated of was classified as hazardous waste, characterized by properties such as toxicity, flammability, corrosiveness, or reactivity that may pose risks to human health, ecosystems, or the environment.43.6% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2020, Taiwan Semiconductor Manufacturing's total waste generation increased by 37.08%, including a 20.15% rise in 2024, reflecting a persistent upward trend that could be linked to operational growth, inefficient material use, or limited investment in waste prevention systems.a
Over the same period, the share of hazardous waste increased by 8.83%, while holding steady in 2024, pointing to potential stagnation in efforts to reduce harmful waste types after a period of worsening performance.a
Overall, Taiwan Semiconductor Manufacturing's waste and hazardousness trends are mixed or inconclusive. A more detailed review of its materials, industry standards, and operational changes would help clarify the net environmental impact of its waste strategy.a
In 2024, Taiwan Semiconductor Manufacturing reported that 445,152 metric tonnes of its total waste output were classified as hazardous. This represents 56.4% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (146.97%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Taiwan Semiconductor Manufacturing has established processes to reduce the environmental burden of its most harmful waste streams.a
