Global: Progress and performance - Air, land and water
In 2014, 6% of the residues resulting from our steelmaking process were regarded as waste for landfill, a 37% improvement over 2013, largely due to increased re-use of by-products at our European ‘long carbon’ steel plants, and higher sales of by-products to external markets within the ACIS region. In our mining operations, however, 33% of the residues produced were treated as waste in 2014, an increase of one third over 2013. The vast majority of this ‘landfill’– 84% - was in the form of displaced rock or ‘overburden’, whilst some 16% took the form of tailings.
The use of production residues as by-products from both steel and mining is reported on in outcome 4.
