Introduction and Summary. This deliverable D1.1, “Variability in material and energy feedstock assessed for the different use cases”, is included in the work package WP 1 “Analysis of variable feedstock to identify challenges for retrofitting” of the project. This report provides the results on the study performed to characterize the material and energy feedstock of steel, aluminium and lead furnace charges, including new or alternative inputs. The study includes, but is not limited to, the following issues: • Analysis of variability of scrap types available or new arising in market • Study of new wastes and alternative charge materials regarding its economic usability • Define elements of interest to detect & quantify (tramp elements, valuable alloying elements…) • Establish metal refining/alloying (micro-addition) requirements Besides these general issues, for each use case some individual tasks of material feedstock analysis were defined: BFI, ▇▇▇ and AMB analysed the variability in the feedstock for the steelmaking use case. The requirements for the steelmaking process with respect to scrap composition in terms of undesired tramp elements (Cu, Sn, P, …) and desired alloy elements (Mn, Cr, Ni, …) were defined. Also, the metallic yield of the different scrap types was analysed. Scrap types with high variability in composition were highlighted. EUT and GRU assessed the inefficiencies in the current production process due to the variability in composition of the Aluminium metal chip feedstock for the aluminium use case.
