Use advice for data set Users of this dataset should account for the specific energy consumption and emission factors associated with converter steelmaking. Consideration should be given to the proportion of hot metal and scrap steel used, as it can significantly influence the environmental impact of the process. Methodological advice includes, but is not limited to, ensuring that any co-products or by-products are allocated appropriately, and the inclusion or exclusion of end-of-life recycling aspects are considered in line with the goal and scope of the assessment.
Technical purpose of product or process This dataset represents the process of converter steelmaking for the production of crude steel, utilizing a mix of hot metal and scrap steel. This process is used in the manufacturing of steel products that require a certain level of purity and structural integrity, such as construction materials, automotive components, and heavy machinery.
