2.6 Manufacture
The starting material for the production of electrical steel at voestalpine is crude steel made in the primary route (blast furnace, LD steelmaking plant) at the Linz site.
The molten crude steel is cast into slabs using a continuous casting method. After cooling, the slabs are reheated in pusher-type or walking beam furnaces to 900 - 1250 °C and rolled to strips of 1.2 - 4 mm thickness in several rolling steps.
A mill scale layer forms on the hot-rolled strip which is removed before further processing in the cold rolling mill (scale removal). This production step first
proceeds through a mechanical loosening of the scale layer (levelling line). The steel strip is subsequently pickled with hydrochloric and sulphuric acid. After pickling, the strip is rinsed, dried, and oiled.
The pickled hot strip is further processed in voestalpine's cold rolling mill. The steel strip can be rolled to thicknesses of between 0.25 and 4 mm. Heat treatment (batch or continuous annealing) is performed in the continuous annealing lines 1 and 2 to restore the formability of the steel strip and to produce a material with certain material properties. Partially it is combined with a varnishing process (horizontal annealing furnace, coater, drying kiln) at voestalpine. Surface finishing with insulating varnish systems ensures improved product properties.
2.7 Environment and health during manufacturing
The production site of the voestalpine Steel Division site is certified according to EMAS 2009, ISO 9001 and ISO 14001.
In compliance with Eco Management and Audit Scheme (EMAS) provisions, voestalpine constantly publishes environment-relevant facts and figures of the production site.
Investments are being made continually in the
expansion of environmental protection measures at the Linz site in an effort to reduce air and water emissions to a minimum. Compliance with all statutory emission limit values has been verified. All production systems approved in accordance by applicable environmental impact analyses are also inspected regularly as part of environmental audits.

3. LCA: Calculation rules
3.1 Declared Unit
This environmental product declaration refers to a declared unit of 1 m² of electrical steel with an average surface weight of 4,3 kg/m² and a reference thickness of 0,55 mm. The LCA result for other thicknesses can be calculated using the linear conversion of the surface weight.
Declared unit
Name Value Unit
Declared unit 1 m²
Mass per unit area 4,3 kg/m²
Conversion factor to 1 kg 0.2326 - Various steel products are manufactured at the site.
The average calculation for electrical steel is weighted by mass. For this, the mean value of the various surface weights of the products was formed based on the total quantity produced.
3.2 System boundary
The life cycle assessment of electrical steel produced by voestalpine refers to a cradle-to-gate analysis with options. The following lifecycle phases are taken into consideration in the analysis:
Module A1-A3 | Production stage
The product stage includes upstream burdens of purchased raw materials (coal, iron ore, pellets, etc.) and the corresponding transport to the production site in Linz. Material and energy flows needed for the coking plant, sintering plant, blast furnaces, steelmaking plant and rolling mill as well as
the continuous annealing lines were recorded on site.
Electricity is provided at Linz in a power station where furnace gases are used as fuel. Since more energy is used than is supplied by this company-owned power station, natural gas and electricity is additionally procured from Austrian networks.
Scrap input in module A1-A3 is regarded as burden- free. Module A1-A3 also includes the production of the product packaging.
Module C3 | Waste treatment
Product flows that reach Module D for recycling leave the product system in C3. Environmental impacts resulting from the grinding and sorting of steel scrap are not included.
Module C4 | Landfilling
Module C4 declares the environmental impacts incurred by landfilling (5% of the product).
Module D | Credits and loads beyond the system boundary
The potential for substituting primary steel with a recycling scenario (95% of the product) is outlined in Module D.
3.3 Estimates and assumptions All assumptions are verified through detailed documentation and correspond to the best possible representation of reality based on the available data.
Regional applicability of the used background data refers to average data under European or German conditions taken from the GaBi 9 database. German data was used for the Austrian market whenever European or Austrian average data were not available.
The estimation of the coating system is based on an average formed from the larger part of the systems used and is considered representative.
3.4 Cut-off criteria
All inputs and outputs for which data are available are included in the LCA model. Data gaps are filled with conservative assumptions from average data (when available) or with generic data and are documented accordingly. Only data with a contribution of less than 1% were cut off. Ignoring such data is justified based on the insignificance of the expected effect. Processes,
materials or emissions known to make a significant contribution to the environmental effects of the products under examination have not been neglected.
Data were collected from the models and
recommendations developed by worldsteel 2017 and tested using available comparable values. It is assumed that the data have been completely recorded and the overall total of ignored input flows do not amount to more than 5% of total energy and mass flows. Environmental impacts of machines, plant and infrastructure were not included.
3.5 Background data
Secondary data are used to depict the background system in the LCA model. These data originate from the v8.7, SP39 GaBi 9 database developed by thinkstep AG.
3.6 Data quality
The foreground data collected at voestalpine Stahl GmbH are based on the quantities used and volumes produced annually. All process data were collected by voestalpine in the course of reporting to official agencies. Data on material and energy use originate from material-specific throughput measurements of various processes as well as from controlling. Data were collected in compliance with worldsteel 2017 provisions and were subjected to a
supplementary plausibility check using material flow analyses of individual process steps. The
technological, geographical and time-related
representativeness of the data base was kept in mind when selecting background data. Whenever specific data were missing, either generic datasets or representative average data were used instead. The implemented GaBi background datasets are not more than ten years old.
3.7 Period under review
Foreground data were collected in the 2017 production year, and the data are based on the volumes produced on an annual basis. Product-specific data for
the continuous annealing lines were taken into account for 2018.
3.8 Allocation
The primary data are allocated using the partitioning approach developed by worldsteel 2014 for calculating life cycle inventories of coproducts in steel production, which is in line with the provisions of EN 15804. The so-called partitioning approach provides for the allocation of environmental effects on the steelmaking process and the emerging byproducts based on physical relations. Material-inherent flow properties are thus taken into account. The pickling byproducts iron sulphate and iron oxide were cut off as a result of their low contribution to company revenue. Economic allocation is not considered to be expedient because the byproducts and co-products are not directly tradable goods. Furthermore, long-term contracts for the sale of the byproducts exist, and the negotiated prices are therefore not subject to market dynamics.
The net flows are calculated by deducting the external steel scrap in A1-A3 from the overall mass of the product.
3.9 Comparability
Basically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to EN 15804 and the building context, respectively the product-specific
characteristics of performance, are taken into account.
The GaBi background database was used to calculate the LCA..
4. LCA: Scenarios and additional technical information
Installation in building (A5)
The end-of-life of the packaging materials is not declared in Module A5.
Name Value Unit
Product packaging for waste
treatment on building site. 0,007567 kg The end-of-life scenario used in this LCA study is based on the following assumptions and thus complies with the specifications published in ökobaudat 2018:
End-of-life (C1-C4)
Name Value Unit
Collected separately 4.3 kg
Recycling 95 % 4.1 kg
Landfilling 5 % 0.2 kg
Re-Use, recovery and recycling potential (D), relevant scenario information
Name Value Unit
Net flow of steel scrap 3,4 kg
This scenario contains a recycling rate of 95%. Since voestalpine externally purchases scrap for steel production, this is offset against the steel scrap for recycling (net flow).

6. LCA: Interpretation
The following interpretation contains a summary of the LCA results referenced to a declared unit of 1 m² electrical steel.
A comparison of the individual lifecycle phases results in a clear dominance of the production phase (Modules
A1-A3). The environmental effects in the production phase are mainly dominated by the direct process emissions of steel production and the supply chain of purchased raw materials and energy carriers.
As a result of product recyclability, the material removed at the end of life can substitute primary steel.
Module D shows the recycling potential of steel at the end of its product life. With the exception of the depletion potential of stratospheric ozone (ODP), this results in credits from the substitution of primary steel for the impact categories investigated. Environmental burdens from the electricity use for the Electric arc furnace (EAF)-process account for the ODP results.
The environmental impact of landfill disposal (C4) represents a minor contribution to the overall environmental impact of the product.
Global warming potential (GWP) from the production phase of electrical steel (Modules A1-A3) can largely be attributed to the raw materials and energy carriers required in primary steel production in the blast furnaces, steelmaking plant, coking plant, sintering plant and heavy plate rolling mill, as well as to the greenhouse gases emitted during these processes.
The greenhouse gases directly emitted from these processes as well as the energetic treatment of the metallurgical gases contribute to a large share of potential global warming.
The main drivers of potential acidification (AP) and eutrophication (EP) are ore and pellet transports. The upstream supply chain of pellets used in production, as well as direct process emissions, also contribute to potential acidification and eutrophication.
Analysis shows that direct emissions at the Linz production site are responsible for a large share of the potential formation of tropospheric ozone (POCP).
Ship transports of pellets and lump ore for the blast
furnaces also generate emissions that further contribute to the formation of summer smog.
The ozone depletion potential (ODP) arises above all from pellets and iron ore used upstream in the blast furnaces and the alloying elements used in the steelmaking plant.
The upstream supply of the alloying elements plays a major role in the abiotic depletion potential of elementary resources (ADP non fossil).
The use of coke represents a main driver of potential abiotic depletion of fossil resources (ADPf) and non- renewal primary energy use (PENRE).
A majority of the renewable primary energy (PERE) is deployed in the upstream supply of the alloying elements, the pellets as well as electricity provision and the production of process gases.
The conversion of the LCA results to other material thicknesses than the declared reference thickness is proportional to the surface weight. This implies a slight imprecision for the coating as these layers are not scalable linearly but surface-related and are dependent on the variation of their thickness on the respective product. The analysis has shown that the impact of the coating itself on the overall result is very small
(contribution of 0,1 % to GWP). In direct comparison, the correct representation of the surface weight of a specific product is more important for the
representativeness of the results.
