About 100 – 200 kg of BOF slag is generated per ton of liquid steel. This material is often used in projects like road construction, but this route provides little energy efficiency gains. Steel slag can also be used in the cement clinker manufacturing process. The result is an increase in clinker production of up to 15% with no net increase in CO2 emissions.

| Energy Savings Potential |
The material requires little or no additional fuel to convert it into cement clinker. |
| CO2 Emission Reduction Potential |
The credits are roughly 0.6 t CO2/t clinker substitute. The total savings potential is approx 50 Mt CO2 (IEA, 2007). |
| Costs |
Technology can easily be Integrated into virtually any existing cement plant at low capital cost. |
