Name
Cold-rolled sheet made from scrap-based electrical steel
Use advice for data set Scope: This Environmental Product Declaration refers to one tonne of cold-rolled sheet manufactured by Salzgitter Flachstahl GmbH, whose slab input material is produced via a scrap-based electric arc furnace route. System boundary: This Environmental Product Declaration is a Cradle to gate" EPD with modules C1-C4 and module D. Modules A1–A3: Product stage The raw material supply stage in module A1 includes the expenses for the provision of materials and energy for the production of steel slabs and their further processing into cold-rolled sheets. In almost all cases, the costs for the production and transport of raw materials are mapped using the LCI database of the Gabi 10 software. Module A2, on the other hand, includes expenses for internal plant material logistics, slab transport between the production sites, and scrap transport. Finally, module A3 contains the direct process emissions of slab production and further processing. Module C1 | Deconstruction / Demolition At the beginning of the disposal stage, the steel products are generally not combined with other materials and can be dismantled by type. The costs associated with dismantling are therefore estimated to be low and negligible. Module C2 | Transport An average distance of 100 km by truck is assumed as a representative scenario for waste management transport. Module C3 | Waste treatment It is assumed that the steel products are shredded before recycling. Module C4 | Disposal Residual materials are not landfilled, as steel is completely recycled. Module D | Benefits and loads beyond the system boundary Module D shows the environmental impacts according to the selected end-of-life scenario (91.6% recycling, 5.3% reuse, 3.1% loss).
Technical purpose of product or process The areas of application for cold-rolled products from Salzgitter Flachstahl GmbH include the following: Automobile and automotive industry Domestic appliance industry Construction industry Building services Drum industry Furniture industry

Technology description including background system The starting material for the cold-rolled sheets are slabs that are produced via a scrap-based electric steel route. The slabs are heated to temperatures of between 1000 °C and 1200 °C for further processing, rolled out into so-called hot strips, pickled in hydrochloric acid and then rolled out again to the desired final thickness. The strips are then recrystallised and annealed to adjust their mechanical properties. Technical data: This EPD covers all cold-rolled sheet products in various steel grades, dimensions, shapes and delivery states. The quality-specific information on tolerance specifications can be found in the corresponding standards. The respective information in the Declaration of Performance also applies. Declared unit: This Environmental Product Declaration refers to the declared unit of one tonne of cold-rolled sheet, whose slab input material is produced via a scrap-based electric arc furnace route.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
