| Use advice for data set | Scope: This Environmental Product Declaration refers to one tonne steel strip from Salzgitter Flachstahl GmbH, whose slab input material is produced using 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 steel strip. 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). | ||

| Technology description including background system | The starting material for steel strip is slabs produced via a scrap-based electric steel route. The slabs are heated to temperatures of between 1000 °C and 1250 °C in heating furnaces for further processing and rolled out to the final thickness and width of so-called hot-rolled wide strips. The hot-rolled wide strips are then uncoiled in the hot-rolled wide strip sheet line and cut into individual strips (sheets) according to the customer's order. Pickled strip sheets pass through a hydrochloric acid pickling line before the hot-rolled wide strip sheet line in order to remove the scale from the surface. Technical data: This EPD covers all steel strip products (continuously hot-rolled sheet from hot-rolled wide strip) in various steel grades, dimensions, shapes and delivery states. The grade-specific information on tolerances can be found in the relevant standards. A selection of standards is listed. EN 10051 applies to the limit dimensions and shape tolerances. For hot-rolled structural steel products, the relevant information outlined in the Declaration of Performance applies. Declared unit: This Environmental Product Declaration refers to the declared unit of 1 tonne of steel strip whose slab starting material is produced via a scrap-based electric arc furnace route. | ||
