FerroSilva and CO2 emissions
A life cycle analysis for steel production using DRI from the FerroSilva process shows a carbon sink of 845 kg CO2 per tonne of steel. Initiallyrees grow and absorb 1205 kg of CO2 from the atmosphere. Subsequent processes create direct or indirect emissions of 360 kg of CO2.
The analysis also considers other influencing factors.
