In 2025, Pertamina Geothermal Energy 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 | 86.01a | 65.53a | 79.69a | |
Total Waste Recovered | 46.82a | 48.74a | 51.33a | |
Total Hazardous Waste Generated | 42.29a | 43.49a | 59.04a | |
Non-Hazardous Waste Disposed | 26.72a | 8.38a | 8.59a |

In 2025, Pertamina Geothermal Energy generated a total of 86metric tonnes of waste.a
Of this amount, 54.44% of Pertamina Geothermal Energy's total waste generated was recovered through methods such as recycling, reuse, or composting, while 45.56% was disposed of through landfilling, incineration, or combustion.a
In 2025, Pertamina Geothermal Energy reported a total waste generation of 86 metric tonnes, of which 54.44% was recovered through recycling, reuse, or composting.This moderate level of recovery indicates that Pertamina Geothermal Energy is taking steps toward improving its waste diversion practices, though there is still room to enhance recycling and recovery efforts.a
Since 2023, Pertamina Geothermal Energy's total waste generation increased by 7.93%, including a 31.25%increase in 2025, 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, Pertamina Geothermal Energy's waste recovery rate declined by 15.49%, with a further 26.81% drop in 2025, underscoring a weakening in waste diversion performance and a potential drift away from circular waste strategies.a
Overall, Pertamina Geothermal Energy is generating more waste while simultaneously backsliding on recovery efforts, both in the short and long term. This dual negative trend raises concerns about the company’s waste management priorities and its alignment with sustainability goals.
In 2025, Pertamina Geothermal Energy generated a total of 86 metric tonnes of waste.a
Of this amount, 49.17% of Pertamina Geothermal Energy'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.50.83% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2023, Pertamina Geothermal Energy's total waste generation increased by 7.93%, including a 31.25% rise in 2025, 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, Pertamina Geothermal Energy reduced the hazardousness of its waste by 33.63%, with a further 25.91% decline in 2025, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.a
Overall, Pertamina Geothermal Energy 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.a
In 2025, Pertamina Geothermal Energy reported that 42 metric tonnes of its total waste output were classified as hazardous. This represents 49.17% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (70.51%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Pertamina Geothermal Energy has established processes to reduce the environmental burden of its most harmful waste streams.a
