Note: the total weight of non-hazardous waste diverted to other disposal operations (GRI 306-5) and the total weight of non-hazardous waste not diverted to disposal through recycling (GRI 306-4), in the fiscal years 2022 and 2023, were reviewed and adjusted in strict accordance with the updated edition of the GRI 306 – Waste Standard, from 2020, ensuring comparability, data quality and transparency of the Company’s environmental performance (GRI 2-4).
The increase in waste generation in 2024 is due to occasional maintenance carried out at the Belo Monte Complex HPPs. Between February and April, maintenance of the leachate tank at the Pimental HPP generated approximately 120 tons of waste, while cleaning of the Belo Monte oil and water separator box resulted in approximately 193 tons of waste, sent for co-processing in Belém (PA). These actions were essential for maintaining structures and preventing environmental impacts.
