It includes credits and loads outside of the system boundaries, such as re-use, recovery or recycling potential.
A comparison with other products is only allowed by a similar application in the building. In principle, a comparison or evaluation of EPD data is only possible if all the datasets are created to be compared to EN 15804 and the product-specific features are considered.64European value of scrap for stainless steel long products.Foreground system: The recycling potential describes the environmental value of stainless steel scrap by capturing the burdens avoided by the use of stainless scrap with a high alloy content to produce stainless steel products as opposed to a route involving carbon steel scrap and the significant input of alloys many of which have high environmental burdens.
The total mass of material to be credited is calculated based on the net stainless steel scrap generated from the system. This is calculated based on the mass of stainless steel scrap sent to recycling at end-of-life minus the input of stainless steel scrap into the product system. The manufacture of rebar products by Outokumpu consumes an average of 233 kg of stainless steel scrap per tonne of rebar product. Assuming a 90% recycling rate, the overall net scrap output is 667 kg scrap/t of rebar (900kg 233kg = 667kg). The manufacture of long products by Outokumpu consumes an average of 725 kg of stainless steel scrap per tonne of product. Assuming a 92% recycling rate, this results in an overall net scrap output of 195kg/t of rebar (920kg 725kg = 195kg). This net approach is reflected by the "open" input of scrap from external sources to the cradle-to-gate processes for the production of stainless steel rebar and long products.
Background system:
Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms.
Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above).
Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered.
Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above).
Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources.Provision of a End of Life service according to the applied technology.LCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massForeground system: Chapter 3.8 EPD.
Background system: For the combined heat and power production, allocation by exergetic content is applied. For the electricity generation and by-products, e.g. gypsum, allocation by market value is applied due to no common physical properties. Within the refinery allocation by net calorific value and mass is used. For the combined crude oil, natural gas and natural gas liquids production allocation by net calorific value is applied.

It includes the "avoided burden" of using stainless steel scrap to produce stainless steel in place of carbon steel scrap and alloys. This data set corresponds with the data set production of stainless steel sheet and a net scrap approach must be adopted to satisfy the input of stainless steel scrap to the stainless steel rebar/long product processes. No specific recycling rate has been applied to this dataset. Users should consider recycling rates appropriate for the planned use of the material.All relevant flows quantifiedThe LCI method applied is in compliance with ISO 14040 and 14044. The documentation includes all relevant information in view of the data quality and scope of the application of the respective LCI result / data set. The dataset represents the state-of-the-art in view of the referenced functional unit.
