Low alloyed steel, aluzinc, galvanized, at plant, 43% zinc, 55% aluminium and 2% silicon, galvanized layer amounts to 6% of steel mass.

Cradle-to-gate. Starts with the production of raw material (pig iron) and ends with galvanization of steel parts.
Processing waste is included, EoL waste of the steel not accounted for.
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.
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.

LCA-data blir brukt i LCA studier for å analysere miljøpåvirkninger av produkter, produktsystemer og tjenester. Dataene er strukturert på en bestemt måte slik at det kan bli brukt i LCA-software.
SØK I LCA-DATA
NorEnviro skal også være en arena som brukere og kunder av miljø- og ressursdata oppsøker for å finne frem til og få tilgang til data og kompetanse, og dermed gjøre det lettere å finne frem i jungelen av miljø- og ressursdata.
