| Use advice for data set | Scope: This environmental product declaration covers steel products rolled out to structural sections, merchant bars and heavy plates, intended for bolted, welded or otherwise connected constructions of buildings, bridges and other structures. This environmental product declaration is valid for the following products: Heavy Plates produced by: - Dillinger with the sites in Dillingen (Germany) and Dunkirk (France) Hot rolled sections produced by: - ArcelorMittal on the sites Differdange (Luxembourg), Dabrowa (Poland), Esch-Belval (Luxembourg), Bergara (Spain), Hunedoara (Romania), Olaberria (Spain), Warszawa (Poland) and Rodange (Luxembourg) - Peiner Träger (Germany) - Stahlwerk Thüringen (Germany) The production shares in this EPD are 26% Basic Oxygen Furnace route (primary steel production) and 74% Electric Arc Furnace route (secondary steel production) based on the total yearly production volume. The data used represent >95% of the annual production of sections and plates from all BauforumStahl member companies. System boundary: Type of the EPD: cradle-to-gate - with options. Module A1-A3, Module C3 and module D were considered. Modules A1-A3 of the structural steel production include the following: The provision of resources, additives, and energy Transport of resources and additives to the production site Production processes on-site including energy, production of additives, disposal of production residues, and consideration of related emissions Recycling of production/manufacturing scrap. Steel scrap is assumed to reach the end-of-waste status once it is shredded and sorted, thus becomes input to the product system in the inventory. Module C3 takes into account the sorting and shredding of after-use steel that is recycled, as well as the non-recovered scrap due to sorting efficiency which is landfilled. A conservative value of 1% landfill is considered. Module D refers to the end of life of the structural steel sections and merchant bars, including reuse and recycling. | ||
| Technical purpose of product or process | Structural steels are intended for bolted, welded or otherwise connected constructions of buildings, bridges and other structures, or in composite steel and concrete structures. Examples are: single storey buildings (industrial and storage halls, etc.) multi-storey buildings (offices, residential buildings, shops, car parks, high rise, etc.) bridges (railway bridge, road bridge, pedestrian bridge, etc.) other structures (power plants, stadiums, convention centers, airports, stations, etc.) | ||

| Technology description including background system | In the integrated steel production route iron ore, (typical mix based on ferro-oxides Fe2O3) coke breeze, circulating components and other additives are mixed and sintered in preparation for being fed into the blast furnace together with coking coke, which is the reducing agent. Also pellets and /or lump may be used. The pig iron produced in the blast furnace is transferred into the basic oxygen furnace. In this vessel, the iron is converted into steel by lowering the carbon content of the iron by blowing oxygen into the melt (exothermic reaction). For temperature control, scrap (up to 35%) is added to the melt. In the electric steel production route scrap is molten in an electric arc furnace to obtain liquid steel. Refining (lowering of sulphur, phosphorous and other tramp elements) and alloying (e.g. about 1% Mn, 0.2% Si) and / or micro-alloying (e.g. about 0.01% V) is applied to give the requested characteristics to the steel. At the end of the steelmaking process, the liquid steel is transformed into a semi-finished product in a continuous casting machine, or in special cases, poured into ingot molds to form blocks. The semi-product (slab, beam-blank, bloom or billet) is hot-rolled into the final product dimensions (heavy plate, wide flats, H-shape, I-shape, U-shape, L- shape and other merchant bars). Quality control: /ISO 9001/ Monitoring according to the product standards, e.g. /EN 10025, Part 1/. Technical data: This EPD is valid for plates and sections of varied grades and different forms of delivery. Specific information on dimension tolerances, constructional data as well as mechanical and chemical properties can be found in the relevant literature and/or the standards. Declared unit: The declaration refers to the functional unit of 1 ton of Structural Steel: Sections and plates. The LCA is calculated based on averaged volume production data of the contributing plants. | ||
