This data set represents the process of producing crude steel, which is an intermediate material used in the steel industry. Crude steel is the raw material for various downstream processing steps that result in finished steel products used in construction, automotive manufacturing, shipbuilding, machinery, and appliances. When utilizing this data set for Life Cycle Assessment, users should consider the technological and geographical specificity of the crude steel production process. Any assumptions regarding the efficiency of energy use, the source of raw materials, and the emissions associated with production need to be clearly defined and appropriate to the context of the assessment. The potential for recycling at the end of life of steel products should be carefully modelled, keeping in mind the energy demands and emissions reductions of recycling processes.
