In 2025, Acciona generated a total of 14,281,961metric tonnes of waste.a
Of this amount, 95.67% of Acciona's total waste generated was recovered through methods such as recycling, reuse, or composting, while 4.33% was disposed of through landfilling, incineration, or combustion.a
In 2025, Acciona reported a total waste generation of 14,281,961 metric tonnes, of which 95.67% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Acciona has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2021, Acciona's total waste generation increased by 67.56%, but declined by 3.9% in the year 2025, suggesting a potential shift toward more efficient material use or the early impact of waste reduction strategies.a
Over the same period, Acciona's waste recovery rate increased by 10.06%, including a 3.35% rise in 2025, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, while Acciona has increased waste over the long term, recent reductions in waste generation and strong improvements in recovery indicate a strategic pivot toward better waste management and more sustainable practices.
In 2025, Acciona generated a total of 14,281,961 metric tonnes of waste.a
Of this amount, 0.27% of Acciona'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.99.73% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2021, Acciona's total waste generation rose by 67.56%, but dropped by 3.9% in 2025, indicating a possible turning point driven by improved waste-reduction practices or production slowdowns.a
Over the same period, the share of hazardous waste decreased by 9.72%, yet rose by 183.05% in 2025, potentially signaling operational variability, temporary setbacks, or less effective hazardous waste mitigation in the short term.a
Overall, Acciona'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, Acciona reported that 39,149 metric tonnes of its total waste output were classified as hazardous. This represents 0.27% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.Only 7.13% of hazardous waste was recovered, meaning the vast majority was treated through disposal methods such as landfilling or incineration. This raises concerns about the environmental and health risks associated with Acciona’s current hazardous waste practices.a
