Environmental data for the production of 1 kg crude steel from SPIN. Transport is added. The coal comes for 65% from Canada, 23% Australia, 12% from the EEC. Iron ore comes for 37% from Brasil, 21% Australia, 31% Europe and the remaining 11% from elsewhere. Lime is imported from Belgium. Metallic alloy elements are assumed to be added in the required percetages. For details on the winning and refining of the elements see [Metallic Elements]. The production and emission data are for 1989.
