Strengthening Recycling Cooperatives

One of the guidelines of Vale’s Waste Management Plan is the valuation of recyclable waste and its allocation to cooperatives near our operating sites. In Brazil’s southeastern state of Minas Gerais, we develop a project to strengthen cooperatives and associations with the goal of increasing the resilience of these organizations and enhancing their capacity to receive recyclable materials such as paper, cardboard and plastics from Vale’s mines. This project aims to generate positive social, environmental and economic impact. 

The project involved 155 waste pickers in nine municipalities. Besides strengthening the unity among cooperative member and opening leadership to new projects and activities, the initiative significantly increased earning and productivity. 

The results include a 25% increase in the sale of recyclable materials and a 72% increase in average monthly revenue. Productivity also grew by 40%, along with improvements in ergonomics and quality of life for cooperative members. Every year, we allocate approximately 400 tons of recyclable waste to cooperatives in the state. This initiative demonstrates Vale's commitment to sustainability and community development, promoting waste management that benefits both the environment and society.

Disposal of Polychlorinated Biphenyls (PCBs)

Vale develops actions to expedite the environmentally appropriate disposal of PCB-containing waste across all operational units. PCBs are organic compounds found in equipment such as electrical transformers and are considered environmental contaminants that can cause impacts to human health and ecosystems.

The company has established a gradual process for disposing of this waste, aligning the maintenance cycles of electrical equipment with the early achievement of PCB disposal targets. In accordance with the Stockholm Convention, the target for ending the use of PCBs is 2025, and the guarantee of environmentally sound final disposal is 2028. To date, Vale has disposed of approximately 406 tonnes of PCB-containing waste.

Regenerating Used Oil

At the Waste Management Center (CMD) in Carajás, Vale has implemented a unit for regenerating used hydraulic oils. The process includes prior analysis of the oils at the source, followed by collection, filtration, regeneration, and reused in maintenance workshops.

We regenerate approximately 1 million liters per year, significantly reducing the need to purchase new oils for the operational units’ maintenance areas.

Recycling Off-Road Tires

Vale allocates scraps off-road tires generated in its operations in Pará and Minas Gerais to recycling companies. Recycling these tires is challenging due to their bulky size, which can exceed four meters in diameter, and their tough steel cord reinforcement that complicates handling and cutting. About 9,000 tons of tires are recycled annually.

The resulting scrap metal is used in the production of rebar for the construction industry. The tires are transformed into coating plates or rubber chips for automotive and cement industries.
