Stainless steel, casted, Primary and secondary production, at plant, 50.1% primary material, 49.9% recycled material

Product name

Stainless steel, casted, Primary and secondary production, at plant, 50.1% primary material, 49.9% recycled material

Reference flow

1 kg

System boundaries

Cradle-to-gate. Starts with the production of raw material (pig iron) and ends with steel making process and casting with oxygen blast furnace and electric converter technologies.

Wastes and end-of-life

Processing waste is included, EoL waste of the steel not accounted for.

Use advice of the dataset

This dataset should be used to model the use of steel produced in Poland and uses ecoinvent 3.7.1 processes in the background. More precisely, • For both steel processing technologies (oxygen blast furnace and electric converter) and the raw material (pig iron) production, the ecoinvent processes have been adjusted to Polish heat and electricity inputs. • The share of recycled and virgin materials is adjusted based on the use of technologies in the country (World steel association, 2019). The dataset generator kindly invites LCA practitioners to share their dataset, if they claim to have a better dataset for this reference product.

Technology description

The share of recycled and virgin materials is based on the use of production technologies in Poland (oxygen blast furnace used for recycled material and electric converter used for virgin material) based on statistics from World Steel Association (2021). For further description of the technologies, see the description of the ecoinvent datasets.
