MUMBAI, Aug. 27 (Xinhua) -- 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, said a steel ministry official, Tuesday.

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.

"LD slag has posed a problem for us as it is not being used at all," said Ruchika Chaudhry Govil, Joint Secretary, Ministry of Steel, Tuesday at a conference on "Promoting Awareness and Usage of Iron & Steel Slag - Ushering in a New Era," organized by industry body FICCI.

As Indian steel production capacity will rise to 300 million tons by 2030 from the current capacity of about 140 million tons, the production of blast furnace slag and LD slag would rise to 27 million tons and 12 million tons, respectively, the FICCI statement said.

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, industry officials said.

In January 2018, India's Tata Steel launched the country's first branded LD slag products for applications in road, fly ash brick and clinker making.
