Strengthening recycling cooperatives

One of the guidelines of Vale’s Waste Management Plan is to maximize the value of recyclable waste and direct it to recycling cooperatives located near its operational sites. In Minas Gerais, we developed a project to strengthen waste picker cooperatives and associations with the goal of increasing their resilience and capacity to receive recyclable materials, such as paper, cardboard and plastics, from Vale’s mining operations. The project aimed to generate social, environmental and economic benefits.

The project involved 155 waste pickers in nine municipalities. As well as strengthening collaboration among cooperative members and expanding leadership opportunities for new projects and activities, the initiative led to significant increases in both earnings and productivity.

The results include a 25% increase in recyclable material sales and a 72% increase in average monthly revenue. Productivity also increased by 40%, along with improvements in ergonomics and quality of life for cooperative members. Each year, we direct approximately 400 metric tons of recyclable waste to waste picker cooperatives in Minas Gerais. This initiative demonstrates Vale’s commitment to sustainability and community development by promoting waste management practices that benefit both the environment and society.

Disposal of polychlorinated biphenyls (PCBs)

Vale is taking steps to accelerate the environmentally sound disposal of PCB-containing waste at all its operational sites. PCBs are organic compounds found in equipment such as electrical transformers. They are considered environmental contaminants and can have harmful effects on human health and ecosystems.

The Company has established a phased disposal process that aligns the maintenance cycles of electrical equipment with the early achievement of its PCB disposal targets. Under the Stockholm Convention, the deadline for ending the use of PCBs is 2025, while the deadline for ensuring their environmentally sound final disposal is 2028. To date, Vale has disposed of approximately 406 metric tons of PCB-containing waste.

Regeneration of used oil

At the Discarded Materials Management Center in Carajás, Vale has implemented a regeneration unit for used hydraulic oil. The process includes analyzing the oil at the source, followed by collection, filtration, regeneration and return to maintenance workshops for reuse.

We regenerate approximately 1 million liters each year, significantly reducing the need for maintenance teams at our operational sites to purchase new oil.

Off-highway truck tire recycling

Vale sends scrap off-highway truck tires generated by its operations in Pará and Minas Gerais to recycling companies. Recycling these tires is challenging because of their size—they can exceed 4 meters in diameter—and the strength of their internal steel mesh, which makes handling and cutting difficult. Approximately 9,000 metric tons of tires are recycled each year.

The resulting scrap steel is used to manufacture reinforcing steel bars for the construction industry. The tires are transformed into flooring panels or rubber chips for use in the automotive and cement industries.
