Data collected on site by steel industry experts in accordance with the worldsteel methodology and ISO 14040
standards, and consistency-checked by worldsteel LCA-experts. Global coke, sinter, pellet, hot metal, slab production based on wordsteel site specific data. Metallurgical
coal data based on global IEA statistics and information from the GaBi database. Iron ore data obtained from iron ore producer. Other upstream data based on the GaBi
database, including country specific electricity. The LCI does not include any further processing beyond the steelworks gate such as bending, shaping, cutting, welding etc.
The LCI includes credits and burdens associated with end of life recycling, applying a burden to the scrap input and a credit for recycling of the product at end of its
life. Therefore, end of life recycling does not need to be modelled separately. Burdens associated with shredding and baling at end of life are not
included.85Data set is based on a weighted average site-specific data (gate-to-gate) of global steel producers. Electricity grid mix is
country-specific. Other upstream data (e.g. iron ore production) are based on global averages from the steel industry.This dataset includes raw material extraction (e.g. coal, iron, ore, etc.), processing, e.g. coke making, sinter,
blast furnace, basic oxygen furnace, hot strip mill and end-of-life recycling. Details on the steel product manufacturing route can be found in Appendices 2 and 3 of the
2011 worldsteel LCA Methodology Report. The steelmaking processes are shown in the flow diagram. Inputs included in the Life Cycle Inventory relate to all raw material
inputs, including steel scrap, energy, water, and transport. Outputs include steel and other co-products, emissions to air, water and land. Further information is given in
the 2011 worldsteel LCA Methodology Report. This LCI includes a credit for recycling of steel at end of life and a burden for steel scrap input during production. This is
the preferred approach adopted by worldsteel, detailed in the 2011 methodology report (Appendix 10).Obtained by passing cold rolled coil through a molten zinc bath, in order to coat the steel with a thin layer of zinc to provide
corrosion resistance. It can be found on the market in coil or in sheets and is further processed into finished products by the manufacturers. Hot Dip Galvanized Steel
features excellent forming properties, paintability, weldability, and is suitable for fabrication by forming, pressing and bending. Applications include domestic
applications, building applications (e.g. wall elements, roofing applications), automotive applications (e.g. body in white for vehicles underbody auto parts), lighting
fixtures, drums and various kinds of sections applications, profiled sheets, etc.BF route.JPGOverview_incl EoL.JPGLCI resultAttributionalNoneAllocation - net calorific valueSubstitution - average, technical properties correctionFull details of the allocation principles are provided in section 4.6 of the 2011 worldsteel Methodology
Report.All data used in the calculation of the LCI results refer to net calorific value.NoneCriteria are set out in the current methodology report for the recording of material flows and to avoid the need to pursue
trivial inputs/outputs in the system. These are outlined below: # All energetic inputs to the process stages are recorded, including heating fuels, electricity, steam and
compressed air. # The sum of the excluded material flows must not exceed 5% on the basis of mass or energy or be environmentally relevant. However, in reality at least
99.9% of material inputs to each process stage are included. # Wastes representing less than one percent of total waste tonnage for given process stages arre not recorded
unless treated outside of the site. Criterion 2 is attainable because site input tonnages are weighed by relatively few inputs such as iron ore, pellets, limestone, scrap,
dolomite, olivine, serpentine, metallic additions, refractories, coke, sinter, hot metal, and intermediate steel products which account for >99% of material inputs to
each process stage.NoneData on steel making unit processes collected on site. Where data is missing for specific relevant flows it is necessary
to provide an average value determined from those sites that have provided the data. LCI modelling is fully consistent.NoneRelevant upstream data (of the GaBi database or other associations) is used according to the worldsteel boundary
conditions, e.g. for iron ore, coke, zinc etc.NoneGaBi databases 2006100.0The World Steel Association Steel Statistical Yearbook, 2010, available via www.worldsteel.org contains information on steel
product tonnages.This data set includes steel production, from cradle to steel factory gate, as well as end of life recycling. In order to incorporate the
impact of using steel scrap in the steel making process, and the recyclability of steel from the product at the end of its life, this LCI uses the worldsteel recycling
methodology. An example of how this is done is provided in the 2011 worldsteel methodology report (Appendix 10). Attention should be made when using this data for studies
that compare steel and cement-replacement concrete using blast furnace or BOF slag, since the substitution approach in the worldsteel methodology means that the benefit of
replacing cement with blast furnace slag may not be consistent with the methodology for accounting for the use of slag in the concrete systems.No statementThe LCI method applied is in compliance with ISO 14040 and 14044. The documentation includes all relevant information in view of the

with the worldsteel position paper on LCA and related ISO14040 set of standards to provide reliable data to meet requests from customers and external studies. Further goals
are to promote the environmental credentials of steel and to develop steel industry expertise in the subject. To quantify resources use, energy and environmental emissions
associated with the processing of 15 steel industry products are currently considered from the extraction of raw materials in the ground through to the finished product at
the steel factory gate. There are also the burdens and credits associated with the recycling of steel scrap considered. The data set represents a "cradle to gate
including end-of-life recycling" inventory. It can be used to characterise the supply chain situation of the respective commodity in a representative manner.
Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs. The data set does not necessarily fit for any
possible specific supply situation - especially if significantly different technology routes exist - but is representative for a common supply chain
situation.worldsteel2016-01-01T00:00:00+01:00ILCD format 1.1thinkstepworldsteel2016-01-01T00:00:00+01:0010.00.000Data set finalised; entirely publishedworldsteelfalseOtherThe worldsteel data in the ILCD database is provided as cradle to gate datasets with and without end of life credits for recycling.
