Waste

Our production process generates mineral and non-mineral wastes. We maintain a waste management program focused on minimization, segregation, traceability, valuation and proper disposal, in addition to encouraging the generation of jobs and income from recycling practices.

The mining and processing activities generate waste called as waste or tailings. These mining wastes have a different management process and are currently disposed of in structures called piles and dams. See more information about dams control and management.

In what concerns non-mineral waste, an efficient management is of great importance to Vale, since it enables us to minimize the environmental impact generated by our activities. This way, our Waste Management Program focuses on the performance of three main fronts:

Lower generation of waste from awareness the operational areas.
Reuse of waste with actions and projects for destination and, in the end, insertion into new production chains and new technologies.
Control and development of new suppliers to receive waste from rigid processes of environmental assessment, reducing the risks related to improper disposal.

KPIs Report

In 2018, 660.8 thousand tons of waste were generated, of which 29.2 thousand can be classified as hazardous and 631.6 thousand non-hazardous. From the total generated waste, 53% were destined to recycling, highlighting the recycling of haul truck tires and conveyor belts, wood packages energy use and composting organic waste.

Performance Evolution

We generated 661 thousand tons of waste in 2018, of which 96% were non-hazardous and 4% were hazardous. There was a significant reduction compared to 2017 (976 thousand tons) due to the sale of the fertilizer business.

Our Management

Vale's waste management program adopts indicators and goals for generation reduction and sustainable destination, which consists of composting, reuse, re-refining and recycling, valuing the use and seeking to reduce landfill disposal, in compliance with SDG 12 -Responsible Consumption and Production.

Risks Overview

As a way to control the destination of waste in Brazil, Vale created the Waste Recipient Audits Program, in which all companies that receive waste from Vale Brazil undergo an environmental assessment and auditing process within a maximum period of three years. During 2018, 130 audits were carried out, for a total of 378 companies actively registered.

Business Case

Wood waste energy use from the Carajás Mine

The Carajás Mine, through a project in partnership with a local company, sought to use wood waste energy to reduce the final disposal in landfills, besides supporting the activities of a local furniture cooperative. The result was the reuse of 220 tons of wood waste during 2018, with potential for expansion in the coming years.

PCBs Destination

Vale has also developed actions to speed up the destination of waste with polychlorinated biphenyls, known as PCBs, in all its operational units, and thus anticipate the goals of the Stockholm Convention for eliminating such materials by 2025, besides ensuring their adequate final disposal by 2028. PCBs are considered environmental contaminants that impact health and ecosystems. In 2018, 150 tons of PCB waste were disposed of in Brazil, including transformer equipment and used oils.

Heavy Recycling Vale

Initiative stirs up the chain that turns waste into social, environmental and economic gains, by recycling 9 thousand tons of tires per year. The waste originated from unserviceable trucks is wholly reused. The scrap metal is converted into construction material, such as rebar. Tires are returned as lagging rubber sheets or are turned into rubber chips. The tire recycling companies set up near Vale’s operations, stimulating the local development.
