Product name
Low alloyed steel, aluzinc, galvanized, at plant, 43% zinc, 55% aluminium and 2% silicon, galvanized layer amounts to 6% of steel mass.
Reference flow
1 kg
System boundaries
Cradle-to-gate. Starts with the production of raw material (pig iron) and ends with galvanization of steel parts.
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 China and uses ecoinvent 3.7.1 processes in the background. More precisely, • For both steel processing technologies (oxygen blast furnace and electric converter), the raw material (pig iron) production and the galvanization process, the ecoinvent processes have been adjusted to Chinese heat and electricity inputs. • The share of recycled and virgin materials are adjusted based on the use of technologies in the country (World steel association, 2021). 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 China (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.
