India’s steel slag waste generated by steel mills will increase from 19 million mt per year at present to 60 million mt per year by 2030 prompting the ministry of steel to collaborate with its counterparts in the ministry of science and technology toward increasing the usage of the waste in road construction, junior minister for steel, Faggan Singh Kulaste, said on Friday, July 21.
Due to the non-availability of efficient disposal methods for steel slag, huge piles of steel slag have arisen around steel plants, becoming a major source of water, air and land pollution. The first road made with steel slag road interpretation technology in Surat, Gujarat, has become famous for its technological excellence at national and international level, he said.
He said that the collaboration between the ministries was aimed at popularizing the Steel Slag Road Technology developed by the Council for Scientific and Industrial Research (CSIR) and the Central Road Research Institute (CRRI).
