Joint Secretary, Ministry of Steel, Ruchika
Chaudhry Govil on Tuesday said that non-usage of LD slag is a
growing problem and the industry needs to learn from other countries’
experiences.
Speaking at a conference on 'Promoting
Awareness and Usage of Iron & Steel Slag - Ushering in a New Era', organised
by FICCI in partnership with Ministry of Steel, Ms
Govil said that the government will facilitate in experience sharing.
"If the world is producing LD slag and this
waste material has an economic value and is being used by other countries.
Instead of inventing the wheel all over again, we need to have information
sharing and collaboration. Ministry of Steel will be happy to act as a
facilitator," she said.
LD slag, a by-product of a steel making process, is
not being used in India unlike the blast furnace slag which is being
commercially used in several applications mainly by cement manufacturers.
Govil said that
the Indian steel industry is looking at 300 million tonnes capacity by 2030
from the current capacity of about 140 million tonnes and this growth will only
increase the production of both blast furnace and LD slag from the current 27
million tonnes and 12 million tonnes per annum, respectively.
"LD slag has posed a problem for us as it is
not being used at all. The LD slag has been accumulating over the years,"
she said, urging the industry to highlight the stumbling blocks and submit
their comments invited by a task force constituted to identify usage of slag in
the next two weeks.
SK Nirmal, Secretary
General, Indian Roads Congress (IRC) said that the IRC has come out with
guidelines for usage of iron and steel slag in road projects and that the
industry should use the code and give their feedback.
On the absence of a code for usage of LD slag
despite some private initiatives in using the slag for road construction in the
country, Mr Nirmal said that the IRC needs to ascertain various issues related
to volumetric instability, vesicular structure, higher water absorption, high
specific gravity, lack of angular structure and environmental impact.
Abhyuday Jindal, Co-Chair, FICCI Steel Committee and Managing Director, Jindal Stainless Ltd
said that though India is the second largest producer
of steel and stainless steel, importance of steel slag utilization is yet to be
realized by the consumption sectors in India.
Pankaj Satija, Chief
Regulatory Affairs, Tata Steel Ltd and Co-Chair, FICCI Mining Committee said
that iron and steel slag is not a waste, but a co-product and it can be used in
different sectors resulting in better resource utilisation and protection of
environment.
SMR Prasad, Consultant,
Environment Management, JSW Steel Ltd cautioned about the utilisation of steel
slag even as he talked about various applications of different types of slags
including using it in coastal areas as wave breakers.
Harinand Rai, Director
(Technical), Steel Authority of India Ltd said that since efforts to reduce
slag production will meet limited success, the industry has to focus on reuse
and recycle of slag which is posing a major challenge.
