Kulaste says huge piles of steel slag have come up around steel plants
Minister of State for Steel Faggan Singh Kulaste says the Steel Slag Road Technology of CSIR-CRRI is playing an important role in realising the mission of ‘Waste to Wealth’.
About 19 million tonnes of steel slag is generated in the country as a solid waste, which will increase to 60 million tonnes by the year 2030, he said at an industry meet organized under the ‘One Week One Lab’ program of Council of Scientific & Industrial Research (CSIR)-Central Road Research Institute (CRRI).
Due to non-availability of efficient disposal methods of steel slag, huge piles of steel slag have come up around the mills, which have become a major source of water, air and land pollution.
The 1st road made with steel slag road interpretation technology in Surat, Gujarat, has become famous for its technological excellence at national and national level.
About one lakh tonnes of steel slag aggregate has been used in its construction, under the technical guidance of CRRI at the Hazira plant of ArcelorMittal Nippon Steel.
No natural ballast of any kind has been used in the construction of this road.
Border Roads Organization has also constructed a steel slag road in Arunachal Pradesh along with CRRI and Tata Steel on India-China border, having a much longer life than conventional road. Similarly, the National Highways Authority of India (NHAI) has also successfully used this technology in road construction on National Highway-66 (Mumbai-Goa) in collaboration with JSW Steel, under the technical guidance of CRRI.
The Minister also informed that the Steel Ministry is working with the Ministry of Science and Technology and Ministry of Road Transport and Highways, for the usage of steel slag road technology throughout the country.
The Steel Slag Road Technology has been developed by the Central Road Research Institute under a research project in collaboration with the Ministry of Steel, and four major steel manufacturing companies of the country, viz., ArcelorMittal Nippon Steel, JSW Steel, Tata Steel and Rashtriya Ispat Nigam.
This technology facilitates the large-scale utilization of waste steel slag of steel plants and has proved very useful in effective disposal of about 19 million tonnes of steel slag generated in the country.
This technique has been successfully tested in road construction in four major states of the country including Gujarat, Jharkhand, Maharashtra and Arunachal Pradesh. Fiinews.com
