Gestão de resíduos e descomissionamento sustentável

We follow the waste management hierarchy established in current legislation: non-generation, reduction, reuse, recycling, treatment of solid waste and environmentally adequate final disposal, with the objective of avoiding or mitigating environmental impacts.  

Since 2013, we have adopted circular economy practices, with emphasis on the reuse of oily sludge in the production of shale oil and green petroleum coke. These practices have reduced the generation of hazardous waste by more than half, from 192,000 tons to 92,000 tons over approximately ten years, minimizing potential negative impacts on the environment and people.11 

In 2025, the reuse of oily residual streams, through the recovery of hydrocarbons in the production of shale oil, naphtha and liquefied petroleum gas (LPG), avoided the generation of approximately 77,300 tons of oily waste.  

In our operations on the Amazon, 100% of organic waste is reused. Everything is segregated, transported to a specific area and treated by composting, generating fertilizer used in seed germination and seedling development to restore degraded areas in the Urucu province. 

In 2025, we invested approximately BRL 87,5 million in research and development projects at the Petrobras Research Center (Cenpes) on technologies related to waste reduction, reuse and valorization. 

In 2025, we generated 92,000 tons of hazardous process solid waste and 200,400 tons of non-hazardous waste, totaling 292,400 tons. The generation of hazardous solid waste was 34% below the internal limit (140,000 tons), and the generation of non-hazardous solid waste was 10% below the internal limit (223.7 tons). 

In 2025, we disposed of 84,300 tons of hazardous waste and 180,200 tons of non-hazardous waste from our processes. Of the total hazardous waste, 80% was destined for RRR routes. The portion of 17,100 tons was destined for non-RRR routes, below the internal corporate limit (17,800 tons). 

For non-hazardous solid waste, 78% was destined for RRR routes. Non-RRR routes totaled 40,400 tons, also below the limit (63,800 tons).

²We report in this chapter the waste information in thousand tons for a better understanding of the quantitative data.

In divestments, we adopt rigorous criteria for the selection of buyers, ensuring their technical, financial and operational capacity to safely continue the business. Our systematics also provides for post-closing monitoring, ensuring that contractual obligations are met and that the new operator adequately implements safety and environmental management. 

Decommissioning involves activities such as: definitive interruption of operations, permanent abandonment and razing of wells, adequate disposal of deactivated facilities, materials, waste and tailings, in addition to the environmental recovery of the areas.  

We monitor discussions on platform dismantling and recycling, bringing the best environmental and market engagement practices to the Brazilian scenario to ensure the sustainable execution of our projects. In 2023, we implemented guidelines for the sustainable disposal of our own floating platforms, reducing the risks of human rights and environmental violations, 

In 2025, we advanced in the decommissioning actions of offshore wells in shallow waters, completing the permanent abandonment of nine wells located in the offshore environment. We also carried out the decommissioning of onshore wells in various concessions, including 13 permanent abandonments, 11 destructions, demolition of the bases of 34 wells and the complete environmental recovery of ten wells that were fully environmentally recovered. 

Over the next five years, we will continue implementing our decommissioning program, with a focus on sustainability, safety, operational efficiency, and care for people and the environment, aiming to consolidate benchmarks and best practices for the industry.
