Steel Slag Aggregates Technology License Granted to AM/NS India, Enabling 'Waste-to-Wealth' in Road Infrastructure through CSIR-CRRI Innovation
Steel slag roads, a promising solution for sustainable infrastructure development, are making waves in India. This innovative technology, which transforms steel industry by-products into valuable construction materials, offers significant advantages such as cost-effectiveness, durability, and environmental benefits.
Roads built with scientifically processed steel slag aggregates are approximately 30 to 40% more cost-effective and can last up to three times longer than standard bitumen roads, reducing repair and maintenance requirements substantially. These roads demonstrate high strength and resilience across diverse environments, from coastal areas to rugged terrains.
ArcelorMittal Nippon Steel India (AM/NS India), a joint venture between ArcelorMittal and Nippon Steel, is at the forefront of this revolution. With a pellet capacity of 20 million tonnes and a crude steel capacity of 9 million tonnes per annum, AM/NS India generates about 1.70 million tonnes of steel slag annually.
Thanks to a collaboration with the Council of Scientific and Industrial Research (CSIR) - Central Road Research Institute (CRRI), AM/NS India can now process this steel slag into specially designed aggregates for road construction. The license allows AM/NS India to manufacture, market, or sell these aggregates under the brand name 'AM/NS Aakar', meeting CSIR-CRRI's technical guidelines, specifications, and quality control measures.
This partnership has already led to the creation of India's first 'all steel slag road' in Hazira, Gujarat. Other notable projects include the world's first coastal steel slag road at a private port in Hazira and the NH-53 diamond bourse road in Surat, which also used 'AM/NS Aakar'.
The Steel Ministry's initiative to promote steel slag road technology supports India's circular economy, which is expected to generate a market value of over $2 trillion and create close to 10 million jobs by 2050. This technology aligns with government initiatives promoting industrial by-product utilization, aiding solid waste management and supporting sustainability goals for road infrastructure.
As India targets steel production growth, steel slag generation is projected to reach 60 million tonnes by FY 2030. Promoting steel slag road technology presents a scalable opportunity to integrate industrial waste use into mainstream infrastructure projects, advancing both economic and environmental objectives.
In conclusion, steel slag road technology in India is a cost-effective, durable, and environmentally sustainable solution that supports the circular economy by efficiently converting industrial waste into long-lasting road infrastructure. This innovation, driven by partnerships between industry leaders like AM/NS India and research institutions like CSIR-CRRI, is set to transform India's road infrastructure for a greener, more sustainable future.
