Indian government has sought inputs from the steel industry for usage of LD slag in the next two weeks as it has been accumulating over the years and posing a problem. LD slag a by product of a steel making process, is not used in India unlike the blast furnace slag which is being commercially used in several applications mainly by cement manufacturers. Ms Ruchika Chaudhry Govil, Joint Secretary Ministry of Steel, at a conference on “Promoting Awareness and Usage of Iron & Steel Slag – Ushering in a New Era” said “LD slag has posed a problem for us as it is not being used at all.”
As Indian steel production capacity will rise to 300 million tonnes by 2030 from the current capacity of about 140 million tonnes, the production of blast furnace slag and LD slag would rise to 27 million tonnes and 12 million tonnes
Industry officials said that Efforts to reduce slag production has met with limited success posing a major challenge to the steel industry. Hence, there is a need to utilize slag in different sectors like roads to protect the environment.
