In 2025, WHA 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) | 2025 | 2024 | 2023 | 2022-2019 |
|---|---|---|---|---|
Total Waste Generated | 6,083.21a | 5,634.8a | 8,020a | |
Total Waste Recovered | 5,655.89a | 5,127.7a | 7,699.14a | |
Total Hazardous Waste Generated | 6.55a | 2.38a | 6.91a | |
Non-Hazardous Waste Disposed | 421.5a | 507.1a | 318.1a |

In 2025, WHA generated a total of 6,083metric tonnes of waste.a
Of this amount, 92.98% of WHA's total waste generated was recovered through methods such as recycling, reuse, or composting, while 6.96% was disposed of through landfilling, incineration, or combustion.a
In 2025, WHA reported a total waste generation of 6,083 metric tonnes, of which 92.98% was recovered through recycling, reuse, or composting.This high recovery rate suggests that WHA has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2022, WHA's total waste generation decreased by 19.69%, yet rose by 7.96% in 2025, potentially indicating a temporary operational shift or inconsistency in waste management outcomes.a
Over the same period, WHA's waste recovery rate increased by 20.77%, including a 2.17% rise in 2025, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, WHA has reduced its waste footprint over time and continues to strengthen its recovery efforts, despite a recent uptick in waste output. This may reflect short-term operational shifts rather than a long-term reversal.
In 2025, WHA generated a total of 6,083 metric tonnes of waste.a
Of this amount, 0.11% of WHA'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.99.89% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2022, WHA's total waste generation fell by 19.69%, but rose by 7.96% in 2025, potentially reflecting a temporary surge in activity or inconsistency in waste control strategies.a
Over the same period, the share of hazardous waste decreased by 7.11%, yet rose by 154.92% in 2025, potentially signaling operational variability, temporary setbacks, or less effective hazardous waste mitigation in the short term.a
Overall, WHA had improved its waste performance over time, but a recent rise in both waste output and hazardousness may reflect operational volatility or a drift from previously effective strategies.a
In 2025, WHA reported that 7 metric tonnes of its total waste output were classified as hazardous. This represents 0.11% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.Approximately 11.15% was managed through recovery methods, indicating a moderate integration of circular practices into its hazardous waste management. However, a significant share was still directed toward disposal, highlighting room for improvement in reducing the long-term impact of hazardous materials.a
