Use advice for data set When applying this dataset in Life Cycle Assessment (LCA), ensure that system boundaries are correctly defined to include all relevant inputs and outputs associated with the converter steelmaking process. Take into consideration the specific energy consumption, emissions, transportation of materials, and the potential for recycling of steel within the defined system boundaries. The technological applicability must reflect current practices, and an appropriate allocation method should be used when the system involves co-products or waste treatment processes.
Technical purpose of product or process This dataset describes the converter steelmaking process which is utilized for producing crude steel from hot metal and scrap steel. The crude steel produced is primarily used in construction, automotive, and machinery manufacturing, due to its high strength and versatility.
