Brajendra Singh, Chief Consultant, Cement Manufacturers' Association, New Delhi. Coal is the principle source of energy in India and will continue to be so for a long-time to come. About 70% of coal production is used in the power sector and the remaining by steel, cement and other consumers.
In China, there are about 30 steel slag cement plants with a combined annual output of 4.8 Mt.However, steel slag quality varies and it is difficult to process, which limits its use. If the total worldwide BOF and EAF steel slag resource of 100 Mt to 200 Mt per year was used this way, the CO2 reduction potential would be 50 Mt to 100 Mt per year.
