Programme Operator BRE Global, Watford, Herts, WD25 9XX, United Kingdom. This declaration is based on the BRE Environmental Profiles 2013 Product Category Rules for Type III environmental product declaration of construction products to EN 15804:2012+A1:2013.
Comparability Environmental declarations from different programmes may not be comparable if not compliant with EN 15804:2012+A1:2013. Comparability is further dependent on the product category rules used and the source of the data, e.g. the database. See EN 15804:2012+A1:2013 for further guidance.
Construction Product Product Description Reinforcing steel bar (according to product standards listed in Sources of Additional Information) that is obtained from scrap, melted in an Electric Arc Furnace (EAF) followed by hot rolling. The declared unit is 1 tonne of carbon steel reinforcing bars as used within concrete structures for a commercial building.

Manufacturing Process Scrap metal is melted in an electric arc furnace to obtain liquid steel. This is then refined to remove impurities and alloying additions can be added to give the required properties. Hot metal (molten steel) from the EAF is then cast into steel billets before being sent to the rolling mill where they are rolled and shaped to the required dimensions for the finished bars and coils of reinforcing steel.

The process flow diagram is shown below:
Construction Installation Processing and proper use of reinforcing steel products depends on the application and should be made in accordance with generally accepted practices, standards and manufacturing recommendations. During transport and storage of reinforcing steel products the usual requirements for securing loads is to be observed.
Use Information The composition of the reinforcing steel products does not change during use. Reinforcing steel products do not cause adverse health effects under normal conditions of use. No risks to the environment and living organisms are known to result from the mechanical destruction of the reinforcing steel bar product itself.
Reference Service Life Reinforcing steel products are in the main building structure so the reference service life will equal the lifetime of the building.

End of Life Reinforcing steel products are not reused at end of life but can be recycled to the same (or higher/lower) quality of steel depending upon the metallurgy and processing of the recycling route. It is a high value resource so efforts are made to recycle steel scrap rather than disposing of it at EoL. A recycling rate of 92% is typical for reinforcing steel bar products. Disposal results in minimal environmental impacts due to the inert nature of the material.
Life Cycle Assessment Calculation Rules Declared / Functional unit The declared unit is 1 tonne of carbon steel reinforcing bars as used within concrete structures for a commercial building (i.e. 1 tonne in use, accounting for losses during fabrication and installation, not 1 tonne as produced).
System boundary The system boundary of the EPD follows the modular design defined by EN 15804. This is a cradle to gate – with all options EPD and thus covers all modules from A1 to C4 and includes module D as well. Impacts and aspects related to losses/wastage (i.e. production, transport and waste processing and end-of-life stage of lost waste products and materials) are considered in the modules in which the losses/wastage occur.
Data sources, quality and allocation Data Sources: This is a manufacturer EPD, a declaration of a specific product originating from one plant. Data Quality: Background data are consistently sourced from PE databases. All these datasets are less than 5 years old. The primary data collection was thorough, considering all relevant mass and energy input and output flows and these data have been verified by UK CARES. Allocation: EAF slag and mill scale are produced as a co-products from the steel manufacturing process; with mill scale also a by-product at the rolling mill. Impacts are allocated between the steel, the slag and the mill scale based on economic allocations. Production losses of steel during the production process are recycled in a closed loop offsetting the requirement for external scrap. Specific information on allocation within the background data is given in the GaBi datasets documentation (GaBi 6 2012).
Cut-off criteria On the input side all flows entering the system and comprising more than 1% in total mass or contributing more than 1% to primary energy consumption are considered. All inputs used as well as all process-specific waste and process emissions were assessed. For this reason material streams which were below 1% (by mass) were captured as well. In this manner the cut-off criteria according to the BRE guidelines are fulfilled.

Module D – Reuse/Recovery/Recycling Potential It is assumed that 92% of rebar is recoverable & available for benefits beyond the system boundary. In the secondary production route, more scrap is required as input to the system than is recovered at end of life (there is also approx. 5% yield loss during the recycling process itself such that 1.05 tonne scrap input is required/tonne product manufactured). The net effect of this is that module D mainly models the burdens associated with the scrap input to the steelmaking process.
Interpretation Scrap-based carbon steel rebar of ArcelorMittal Hamburg GmbH (member of UK CARES) is made via the EAF route. The bulk of the environmental impacts and primary energy demand is attributed to the manufacturing phase, covered by information modules A1-A3 of EN 15804. For GWP for instance, A1-A3 impacts account for 84.96% overall life cycle impacts for this category.
