- Done through recirculation of sinter off-gas back to sinter strand by utilizing CO-content of the gas
- Reduction of amount of waste gas to the stack by up to 50%
- Reduction of coke consumption by up to 10%
- Lower investment costs for gas-cleaning facilities, e.g. DeSOx/DeNOx systems
- Reduction of SOx and NOx freight to the atmosphere
