World record: India's waste road enters Guinness Book
An infrastructure project in Raigra, India, has been recognized by the Guinness World Records as the longest road built from processed steel slag. The 1.85 km road, developed in collaboration with Jindal Steel and the Central Road Research Institute, achieves up to 40% cost savings and reduces environmental impact.
An exceptional infrastructure project in Raigra, Chhattisgarh, India, has received official recognition from the Guinness World Records as the longest road built exclusively from processed steel slag. The 1.85-kilometer, four-lane road was developed by Jindal Steel in partnership with the Central Road Research Institute. Construction utilized approximately 200,000 tonnes of processed steel slag, completely replacing natural materials in its various layers. The process of converting waste into infrastructure material involved extracting trapped metal, crushing, screening, and rigorous grading. The material underwent physical, mechanical, and environmental testing and was approved for use. The road was designed to withstand heavy truck traffic. Engineers estimated the road structure is about 35% thinner than a conventional road, with up to 40% savings in construction costs. Using processed slag saved the mining, quarrying, and transportation of about 200,000 tonnes of virgin rock. Jindal Steel Chairman Navin Jindal said India's growth must be driven by innovation that creates economic value while protecting the environment. Minister of Science and Technology Jitendra Singh praised the move as an expression of the country's ability to translate scientific innovation into practical infrastructure solutions.
