The industrial process described is involved in the production of hot metal through blast-furnace ironmaking, utilizing raw materials such as sinter, pellets, lump ore, and scrap iron. The process is implemented within a single operational unit identified as 'Z4' within the plant carrying the same name. This hot metal is typically used for further processing in steelmaking facilities to produce various grades and forms of steel. When using this data set, attention should be given to the methodological consistency with the overall Life Cycle Assessment (LCA). Users must consider the boundary conditions of the data, such as the specific technological stage represented (high-temperature ironmaking process). It's important to note whether the data include or exclude subsequent steelmaking and any recycling of materials. If combining this data with other data sets in an LCA, ensure compatibility in terms of technological epoch and geographical location. Verify that environmental impact indicators are coherent and comparable.
