Vale undertakes actions to expedite the environmentally correct disposal of waste containing PCBs at all operations units. PCBs are organic compounds found in equipment such as electrical transformers, and they are considered environmental contaminants, posing risk to health and ecosystems.

The company has established a gradual process for the disposal of this waste, aligning the maintenance cycles of electrical equipment with the anticipation of PCB disposal targets. According to the Stockholm Convention, the goal for ending PCBs use is 2025, with the assurance of environmentally sound final disposal by 2028. To date, Vale disposed of approximately 350 tons of PCB-containing waste.
