WASTE MANAGEMENT Waste rock and tailings are the two largest waste streams produced at IGO's operations. The Nova and Jaguar Operations produced both, whereas the Long Operation produces only waste rock. The waste rock is stored and managed in accordance with statutory guidelines and internal standards to minimise its potential to cause environmental impact and ensure the effective rehabilitation of our mine sites both progressively and at closure. The responsible management of landfill waste is also an important aspect of IGO’s waste management strategy. Across the Group, waste disposed to landfill has been increasing, however this is consistent with the growth of our business (see Figure 24 to 26). IGO undertakes recycling programs at all our sites, with a focus on steel, hydrocarbons and cardboard. In FY18, IGO generated 2,738 tonnes of waste to landfill.
