| Use advice for data set | Scope: This Environmental Product Declaration refers to one tonne average heavy plate (average EPD) from the rolling mills of Ilsenburger Grobblech GmbH in Ilsenburg and Salzgitter Mannesmann Grobblech GmbH in Mlheim an der Ruhr. Both are members of the Salzgitter Group. The heavy plate products are rolled from slabs produced via the scrap-based electric steel route. System boundary: This Environmental Product Declaration is a Cradle to gate EPD with modules C1-C4 and module D. The life cycle phases are as follows: Module A1 | Raw material supply The module covers slab production according to the scrap-based electric steel route, including raw material upstream chains. ILG and MGB procure scrap-based electric steel slabs for the production of heavy plate from different steelworks. To take this into account, a database data set for German electric arc furnace (EAF) steel is being implemented to model slab production. This contains average material and energy flows of a scrap-based electric steel plant based on data from several German steel manufacturers. Module A2 | Transport The slabs are transported by electric goods trains from the production site to the plants in Ilsenburg and Duisburg, with an average distance of 100 kilometres assumed as representative. Module A3 | Manufacture Heavy plate production balances all energy and material flows in the production of Ilsenburger Grobblech GmbH and Salzgitter Mannesmann Grobblech GmbH and forms weighted average values according to the total production volume shares. Module C1 | Deconstruction / Demolition At the beginning of the disposal stage, heavy plate is generally not combined with other materials and can be dismantled by type, which is why the costs incurred are so low compared to the production stage that they are assumed to be negligible. Module C2 | Transport An average distance of 50 km by truck is assumed as a representative scenario for waste management transport. Module C3 | Waste treatment Dismantled heavy plate hardly needs to undergo any further processing steps, as its use generally already fulfils the requirements of the recycling processes in terms of purity, environmental and health regulations. No environmental impact is therefore anticipated. Module C4 | Disposal The environmental impact of all mass fractions that are not reused or recycled (3.1%) and are therefore landfilled is declared in module C4. Module D | Benefits and loads beyond the system boundary Module D presents the environmental impacts according to the selected end-of-life scenario (91.6% recycling, 5.3% reuse, 3.1% landfill). | ||
| Technical purpose of product or process | The areas of application for heavy plate products from Ilsenburger Grobblech GmbH and Salzgitter Mannesmann Grobblech GmbH include the following: Wind power plants (on- and offshore) Steel and bridge construction Tank and plant construction Pipelines Yellow goods (high-strength and wear-resistant steels for vehicle and crane construction) Mechanical engineering and metal construction Shipbuilding | ||

| Technology description including background system | The starting material for the declared heavy plate products from the rolling mills of Ilsenburger Grobblech GmbH and Salzgitter Mannesmann Grobblech GmbH are slabs produced via the scrap-based electric steel route. The slabs are reheated in the rolling mills' heating furnaces to temperatures between 1,000 °C and 1,250 °C and rolled out in a reversing rolling process to produce heavy plate in the lengths and widths individually defined by the customer. The rolling stands of Ilsenburger Grobblech GmbH and Salzgitter Mannesmann Grobblech GmbH are so-called quarto rolling stands, consisting of four rolls: two work rolls and two back-up rolls. Technical data: This EPD covers all heavy plate products in various steel grades, dimensions, shapes and delivery states. The grade-specific information on tolerances can be found in the relevant standards (e.g. EN 10029 and EN 10025). Furthermore, the respective information in the Declaration of Performance applies: Declared unit: This Environmental Product Declaration refers to the declared unit of one tonne heavy plate. | ||
