In 2025, Enagas generated a total of 9,251metric tonnes of waste.a
Of this amount, 98.29% of Enagas's total waste generated was recovered through methods such as recycling, reuse, or composting, while 1.71% was disposed of through landfilling, incineration, or combustion.a
In 2025, Enagas reported a total waste generation of 9,251 metric tonnes, of which 98.29% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Enagas has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2021, Enagas's total waste generation increased by 78.08%, including a 230.11%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, Enagas's waste recovery rate increased by 2.38%, including a 2.67% rise in 2025, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, Enagas has seen a consistent rise in waste generation both over the long term and in the year 2025. 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.
In 2025, Enagas generated a total of 9,251 metric tonnes of waste.a
Of this amount, 57.79% of Enagas'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.42.21% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2021, Enagas's total waste generation increased by 78.08%, including a 230.11% 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
Since 2025, Enagas's hazardous waste generation has increased by 12.1%, indicating a potential rise in the use of harmful materials, process inefficiencies, or limited hazardous waste reduction strategies..a
Overall, Enagas'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 2025, Enagas reported that 5,346 metric tonnes of its total waste output were classified as hazardous. This represents 57.79% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (99.06%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Enagas has established processes to reduce the environmental burden of its most harmful waste streams.a
