Tata Steel Leads Green Road Initiative with Industrial Waste
Over 20 lakh metric tonnes of fly ash and LD slag repurposed to build National Highway 55 bypass, reducing environmental impact and enhancing road infrastructure
In a major push toward sustainable infrastructure, Tata Steel Meramandali (TSM) has pioneered the use of industrial waste in the construction of the Angul bypass on National Highway 55. By repurposing over 20 lakh metric tonnes of fly ash and LD slag—by-products of the steelmaking process—TSM is setting a benchmark in eco-friendly road development.
Fly ash generated from TSM’s captive power plant and LD slag from the Basic Oxygen Furnace process are being used extensively in the road construction. This initiative not only helps in effective waste management but also significantly reduces the dependence on natural construction materials such as soil, stone, and sand.
The project is being executed in strict compliance with environmental guidelines issued by the Central Pollution Control Board (CPCB), the National Highways Authority of India (NHAI), and the Odisha State Pollution Control Board (OSPCB). In the financial years 2023–24 and 2024–25, TSM has supplied approximately 10.73 lakh metric tonnes of fly ash and 9.56 lakh metric tonnes of LD slag for the bypass construction.
Officials from NHAI, which is overseeing the bypass project, have commended the initiative, emphasizing that using industrial waste in construction is a significant step toward sustainable development. Reusing materials like fly ash and LD slag helps preserve natural resources and contributes to circular economy practices, aligning with national goals on environmental conservation and climate resilience.
This environmentally conscious construction technique also has far-reaching economic benefits. It cuts down on the cost of raw materials, supports waste reduction, and opens avenues for the large-scale use of similar industrial by-products in future infrastructure projects across the country.
According to TSM representatives, the Angul bypass is expected to alleviate traffic congestion within the city limits of Angul, improving transport efficiency and reducing vehicular pollution. As a result, residents and businesses alike will benefit from better connectivity and smoother commuting experiences.
Tata Steel’s commitment to environmental stewardship through such innovative practices underscores the role of industry leaders in shaping a greener future. With this project, the company reinforces its dedication not only to business excellence but also to social and environmental responsibility.
The Angul bypass stands as a testament to how industrial innovation and sustainability can go hand-in-hand, setting a precedent for green infrastructure across India.
