Jindal Steel Earns Guinness Recognition for World’s Longest Slag Road
Jindal Steel helped build a road in Chhattisgarh using steel-making waste called slag.
The road is 1.85 kilometers long and has four lanes.
About 200,000 tonnes of processed slag were used instead of natural stones.
Guinness World Records recognized it as the longest road made entirely with processed steel slag aggregates.
Using slag could reduce the need for quarrying natural materials.
Jindal Steel says these roads can cost less and last longer than ordinary bitumen roads.
Government ministries are supporting the wider use of this technology.
The project is an example of turning industrial waste into something useful.
Jindal Steel Limited and CSIR-Central Road Research Institute built a 1.85-kilometer four-lane road in Raigarh, Chhattisgarh.
The road used around 200,000 tonnes of processed steel slag aggregates instead of natural aggregates.
Guinness World Records recognized it as the longest road built exclusively with processed steel slag aggregates.
Jindal Steel said slag roads can be 30–40% more cost-effective and last up to three times longer than standard bitumen roads.
Indian ministries are promoting the technology as steel slag production is expected to reach 60 million tonnes in the next few years.
