The "value of scrap" approach addresses the question on how to deal with the recycling of stainless steel scrap at products EoL in an LCA/LCI.
The principle idea behind the approach is to define the ecoprofile/LCI of stainless steel scrap, describing the so-called "value of scrap". The calculation of the "value of scrap" is based on the difference in LCI of the 100% primary and 100% scrap route (theoretical calculation) under consideration of the process yield of the recycling step.
The "value of scrap" (= stainless steel scrap LCI) is then used to account for a potential net surplus or debit of stainless steel along the life cycle of a stainless steel product.

These underlying datasets cover the following technology and background system:
Stainless steels are manufactured from mixtures of stainless scrap, carbon steel scrap and ferro-alloys of Cr, Ni and Mo. The proportions of these raw materials can vary greatly, depending upon the steel grade and other factors.
Initially, the raw materials are melted in an electric arc furnace (EAF); the liquid metal is then transferred to a decarburising vessel (usually "argon oxygen decarburising", AOD) where it is refined by blowing with various mixes of argon, oxygen, nitrogen. The liquid steel is then finished in a ladle furnace (LF), where the chemistry is fine-tuned and the temperature is optimised for subsequent processing.
The liquid steel is transformed into a solid product by continuous casting. For flat product production the section is rectangular, known as "slab".
Slabs are converted into rectangular (quarto) plates or long coils by reheating and hot-rolling. Subsequent heat treatment (annealing), acid cleaning (pickling) and flattening produces finished quarto plate or white hot rolled coil products.
Alternatively, the white hot rolled coil is used as the feedstock for producing thinner coil products, by cold rolling. The white hot rolled coil is cold rolled; then it is softened & acid pickled or bright annealed, and flattened (skinpass rolled) to form the Cold Rolled Coil product.LCI resultAttributionalnoneGaBi Modelling PrinciplesGaBi databases85.0For details contact Eurofer (European data): www.eurofer.org.For details contact Eurofer (European data): www.eurofer.org.No statementFor details please contact the European Confederation of Iron and Steel Industries, Eurofer (European data): www.eurofer.org.Tomas RydbergFor details please contact the European Confederation of Iron and Steel Industries, Eurofer (European data): www.eurofer.org.thinkstep2020-01-01T00:00:00.000ILCD format 1.1thinkstep2020-01-01T00:00:00.00000.00.001Data set finalised; entirely publishedNREL US Life Cycle Inventory (USLCI) LibraryVarious (NREL USLCI)trueFree of charge for all users and usesGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
