Use of EAF slag - CemStar®Costs & Benefits
|Parent Process: Alternative Raw Materials|
|Energy Savings Potential||
As the calcination energy demand is estimated to be 1.9 GJ/t-clinker, substituting 10% of clinker with steel slag will reduce energy consumption by 0.19 GJ/t-clinker.
|CO2 Emission Reduction Potential||
Replacing 10% of clinker by steel slag can reduce CO2 emissions by approximately 11%
Equipment costs are mainly for material handling and vary between US $200,000 and $500,000 per installation. Total investments are approximately double the equipment costs. CemStar® charges a royalty fee.
Use of EAF slag - CemStar® Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for Cement Making, discusses energy efficiency practices and technologies that can be implemented in cement manufacturing plants. This ENERGY STAR guide provides current real world examples of cement plants saving energy and reducing cost and carbon dioxide emissions.
