Scrap recycling in steel industry plays a crucial role in green technology development by reducing CO2 emissions. Plant scale predictions on effectiveness of steel scrap recycle have been rarely attempted. A life cycle inventory (LCI) based methodology for plant CO2 emissions is developed using process modeling of different primary stages (blast furnace basic oxygen process and directly reduced iron electric arc furnace (EAF) process with scrap additions). Emission data from primary stages is used for secondary processing stages for predicting the scope of further reduction.
