Home Environment Waste 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.
