Jindal Steel enters Guinness World Records with 1.85-km road built from steel slag

According to fresh market updates, Jindal Steel has received recognition from the Guinness World Records for constructing the world's longest road using steel slag aggregates.

Steel slag is a waste by-product of the steel manufacturing process.

Jindal Steel Limited, in collaboration with CSIR-Central Road Research Institute (CSIR-CRRI), has achieved a Guinness World Records title for constructing the longest road built exclusively with processed steel slag aggregates at Raigarh in Chhattisgarh, a firm statement stated Saturday.

Naveen Jindal, Chairman, Jindal Steel Limited, stated: "The achievement reveals how science, technology and industry can transform industrial co-products into valuable resources for nation-building." India's expansion must be powered by innovation that creates economic value while protecting the environment. Waste-to-wealth is one of the focus areas of the government to backing the circular economy, Jindal, who is additionally the President of the industry body Indian Steel Association (ISA), stated.

Jitendra Singh, Minister of Science & Technology, Government of India, stated the road is a firm demonstration of India's ability to translate scientific innovation into practical infrastructure solutions.

By transforming steel slag into a high-value resource for road construction, the project showcases the potential of indigenous technology to address real-world challenges, he stated.

Scientifically processed steel slag for roads provides significant advantages over traditional construction materials. The steel slag roads are around 30 to 40 per cent more cost-effective and can last up to three times longer than standard bitumen roads, reducing repair and maintenance needs. Their resilience makes them suitable for diverse climate conditions- from coastal regions to rugged terrains.

Steel slag generation is anticipated to reach 60 million tonnes in the next few years, considering the ongoing capacity augmentation in Indian steel plants with an aim to produce 300 million tonnes of steel by 2030-31.

The steel ministry is promoting the usage of steel slag road technology and actively collaborating with the Ministry of Science & Technology and the Ministry of Road Transport & Highways to facilitate the large-scale utilisation of the industrial by-product.
