Andrew Woollett: We realised there was an interesting opportunity in urban resources i.e. waste material, in electric arc furnace dust. The biggest use of zinc is in galvanising, which is simply coating a thin layer of zinc on steel to stop it rusting. About a third of the world's steel comes from recycling and when it is recycled it is – simply …
