ArcelorMittal Nippon Steel India (AM/NS India) has become the first company in the country to secure a license from CSIR–Central Road Research Institute (CRRI) for a breakthrough technology that processes steel slag aggregates for road construction. The license, issued under the Ministry of Science & Technology, empowers AM/NS India to apply the CSIR-CRRI’s scientifically validated method at its Hazira, Gujarat plant.
This strategic move aligns with the government’s ‘Waste to Wealth’ vision and supports India’s net-zero goals by promoting circular economy practices. AM/NS India’s specially designed product, ‘AM/NS Aakar’, already meets CRRI’s stringent quality standards and has been used in India’s first “all steel slag road” and a coastal road project at Hazira.
According to CSIR-CRRI’s Satish Pandey, steel slag roads are significantly more cost-effective and durable than conventional roads. With India generating 19 million tonnes of steel slag annually—expected to surge to 60 million tonnes by 2030—the technology promises massive environmental and economic benefits. In Kolkata, infrastructure developers are increasingly seeking sustainable alternatives to reduce costs and improve durability. The adoption of steel slag roads could provide a viable solution for the region’s growing urban and industrial infrastructure demands.
