Exercise 1: Primary and secondary steel production 1) Using the inventory information in Table 1, calculate the indicator results for the fol- lowing two reference flows: a. 1000 million metric tons of steel from the BF/BOF route (primary steel) *) b. 1000 million metric tons of steel from the EAF route (recycled steel) *) (1000 million metric tons was roughly the annual world production of crude steel in 2004). Consider only the following impact categories and characterization factors: Climate change (GWP100) Photo-oxidant formation (POCP high NOx) Acidification (AP incl. fate)
