Rashtriya Ispat Nigam Ltd, the corporate entity of Vizag Steel, is mulling setting up of a cement plant as part of its plans to dispose byproducts such as slag and fly ash, a senior company official said.
RINL may also enter into a long-term contract to supply these byproducts to prevent their accumulation that can lead to environmental issues.
"We may enter into a joint venture partnership for setting up a cement plant," the official said.
"Fly ash, a byproduct from our power plant, is getting accumulated which may create environmental issue in future. We may also enter long-term agreement for supplying these products. There will be clarity in a few days," the official
"For the cement plant, we may require land from the government which is again a process involving Cabinet decisions and other procedures. The total cost for setting up cement plant is estimated to be around Rs 1,000 crore. It is still in premature stages," the official said.
Slag is a partially vitreous by-product of the process of smelting ore, which separates the desired metal fraction from the unwanted fraction.
Fly ash, is one of the residues generated in combustion, and comprises the fine particles and released in coal-fired power plants.
The setting up of a cement plant has become urgent in view of the capacity expansion of RINL from 3 million tonnes to 6.3
RINL has ambitious plans to take up further expansion to 16 million tonnes by 2020.
According to the official, the steel plant produces around 1.8 million tonnes of slag every year.
Fly Ash, which is mainly generated from its power project, also runs into thousands of tonnes every year, the official said.
Disposal of fly ash and slag becomes a major problem and like other steel majors, RINL has no choice but to set up the cement unit, industry experts said, adding that the steel maker has to find ways to dispose of the waste before it becomes environmentally hazardous.
