RECYCLING AND UTILIZATION OF SOLID WASTE

Generation of slags are very high in Indian steel plants due to presence of higher ash content of coal, higher alumina and silica content in iron ore as compared to other developed countries. This can be avoided by proper combination of indigenous and imported coals and increased use of washed low alumina iron ore during sintering and Blast Furnaces operations. This will reduce metallurgical slag.

Since 1918, The NSA has promoted the use of Blast Furnace and Steel Furnace Slag. Blast Furnace slag has been called the "All-Purpose Aggregate" as it can be used in all construction applications as either a normal weight or lightweight (expanded or pelletized) aggregate depending on how it was formed and processed. Blast Furnace Slag is also quickly quenched by water or air to produce Granulated Blast Furnace Slag.
