What are the principal areas covered by the data?
The major material flows covered are quantified and categorised under five headings: resource use including energy and water; air emissions; water emissions; by-product and wastes. The range of data collected from different sites reflects different ironmaking and steelmaking practices, energy efficiencies, national power mixes and efficiencies, and the complexity of the finishing operations. The inventory includes at least 99% of the total waste tonnage for given process stages and that are treated on site. Certain data are included in the study but not accounted in the global averages (see section 3.3).
