| Use advice for data set | Scope: This Environmental Product Declaration refers to one tonne of unpickled hot-rolled wide strip manufactured by Salzgitter Flachstahl GmbH. 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 hot-rolled wide 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 input material for unpickled hot-rolled wide strips are slabs that are produced via an ore-based blast furnace route and cast in a continuous process on a continuous casting machine. The slabs are heated to temperatures of between 1100 °C and 1250 °C for further processing, rolled out into hot-rolled warm strips of the desired size, and wound as so-called coils. Technical data: This EPD covers all unpickled hot-rolled wide strip products in various steel grades, dimensions, shapes and delivery states. The quality-specific information can be found in the corresponding standards. A selection of standards is attached. The EN 10051 standard applies to the limit dimensions and shape tolerances. Declared unit: This Environmental Product Declaration refers to the declared unit of one tonne of unpickled hot-rolled wide strip whose slab input material is produced via an ore-based blast furnace route. | ||
