| Use advice for data set | Scope: This Environmental Product Declaration refers to one tonne of FolaSal® or FolaSal®StronSal® from 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: Production 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 FolaSal® and FolaSal®StronSal® steel sheets. The costs for the production and transport of primary materials are mapped in almost all cases 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 from slab production and further processing. Module C1 | Dismantling At the beginning of the disposal stage, the steel products are generally not combined with other materials and can be dismantled by type. The expenses 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 There is no landfilling of residual materials, as steel is fully recycled – see also 3.4. Module D | Benefits and loads beyond the system boundaries Module D shows the environmental impacts according to the selected end-of-life scenario (91.6% recycling, 5.3% reuse, 3.1% loss – see also 3.4). | ||
| Technical purpose of product or process | The areas of application of FolaSal® and FolaSal®StronSal® steel products from Salzgitter Flachstahl GmbH are used in the following areas, among others: Automotive and automotive supply industry Domestic appliance industry Construction industry (e.g. roof and wall profiles) Air conditioning, ventilation and drainage technology Building services Shelf and switch cabinet construction Furniture industry Packaging industry | ||

| Technology description including background system | The starting material for coil-coated cold-rolled sheets are slabs that are produced via a scrap-based electric furnace route. For further processing, the slabs are heated to temperatures of between 1100 °C and 1250 °C, 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 annealed in a recrystallising process to adjust the mechanical properties and, depending on the application, can be coated with a zinc or zinc/aluminium/magnesium alloy in order to protect them cathodically against corrosion. Electrolytic galvanising of the steel strips is also possible. To further improve the anti-corrosion properties and surface appearance, the galvanised or non-galvanised coils are then coated with paint or foil. The products of this coil coating process from SZFG bear the brand name FolaSal® or FolaSal®StronSal®. Technical data: This EPD covers all coil-coated products in various steel grades, dimensions, shapes, and delivery states. The grade-specific information on tolerances can be found in the relevant standards. Declared unit: This Environmental Product Declaration refers to the declared unit of one tonne of FolaSal® or FolaSal®StronSal® sheet steel, whose slab starting material is produced via a scrap-based electric arc furnace route. | ||
