In 2025, Elisa generated a total of 1,125metric tonnes of waste.a
Of this amount, 81.16% of Elisa's total waste generated was recovered through methods such as recycling, reuse, or composting, while 18.84% was disposed of through landfilling, incineration, or combustion.a
In 2025, Elisa reported a total waste generation of 1,125 metric tonnes, of which 81.16% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Elisa has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2021, Elisa's total waste generation increased by 74.42%, including a 34.13%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.ab
Over the same period, Elisa's waste recovery rate declined by 14.6%, and then remained stable in 2025, possibly indicating that earlier setbacks have leveled off without signs of active improvement.ab
Overall, Elisa’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 2025, Elisa generated a total of 1,125 metric tonnes of waste.a
Of this amount, 52.44% of Elisa'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.47.56% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2021, Elisa's total waste generation increased by 74.42%, including a 34.13% 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.ab
Over the same period, the share of hazardous waste in Elisa's total output increased by 15.44%, including a further 23.4% rise in 2025, suggesting a troubling upward shift toward more environmentally harmful waste streams that could raise compliance costs and environmental risks.ab
Overall, Elisa has seen a continuous rise in both total waste and hazardous waste over time, signaling a worsening environmental impact that may require urgent reassessment of material sourcing, production processes, or waste mitigation strategies.ab
In 2025, Elisa reported that 590 metric tonnes of its total waste output were classified as hazardous. This represents 52.44% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (99.42%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Elisa has established processes to reduce the environmental burden of its most harmful waste streams.a
