Jindal Steel builds world's longest steel slag road in India
Jindal Steel built a long road in Raigarh using waste from steel factories.
The waste, called steel slag, was processed to make strong road-building material.
The road is 1.85 kilometres long and has four lanes.
Guinness World Records recognised it as the longest road of its kind.
About 2 lakh tonnes of processed slag were used.
Scientists helped crush, clean and grade the material before it was used.
The road was tested for environmental safety and for heavy trucks.
It is thinner than a regular road and cost less to build.
The project shows how industrial waste can be reused instead of relying as much on natural stone.
Jindal Steel built a 1.85-kilometre, four-lane road in Raigarh, Chhattisgarh.
The road uses 100% processed steel slag generated as waste from the company’s factories.
Guinness World Records recognised it as the world’s longest steel slag road.
Nearly 2 lakh tonnes of processed slag were used, reducing reliance on natural stone excavation and mining.
The road is about 35% thinner and delivered approximately 40% construction-cost savings compared with conventional roads.
