In a move that signals a shift in how India views both waste and infrastructure, the government has initiated the transfer of an indigenous bio-bitumen technology developed by the Council of Scientific and Industrial Research (CSIR) for large-scale industry adoption.

The technology, which converts agricultural residues into a renewable alternative to conventional bitumen, was formally handed over during a technology transfer event in New Delhi.

At its core, the innovation reframes farm waste—not as a disposal challenge, but as a feedstock for high-value infrastructure. By doing so, it directly addresses two persistent issues: stubble burning and India’s reliance on imported bitumen.

Linking agriculture, climate goals, and roads

Union Minister Shivraj Singh Chouhan described the development as a “transformative step” that connects agriculture with infrastructure and innovation. The use of farm residue for road construction, he noted, not only aligns with India’s Net Zero ambitions and circular economy goals, but also creates an additional income stream for farmers.

The technology also fits into broader policy frameworks such as Atmanirbhar Bharat and the National Bio-Energy Mission—highlighting how climate action is increasingly being embedded within industrial and infrastructure strategies.

Performance meets sustainability

According to Jitendra Singh, the bio-bitumen has demonstrated durability and compatibility with conventional bitumen, while significantly lowering the carbon footprint. This positions it as a viable candidate for large-scale deployment, including national highway projects.

The technology has been jointly developed by CSIR–Central Road Research Institute and CSIR–Indian Institute of Petroleum using a thermochemical conversion process that transforms lignocellulosic biomass into a usable binder for road construction.

From lab innovation to market adoption

For CSIR, the transfer marks more than just a technological milestone—it signals the transition of bio-based materials from laboratory research to real-world infrastructure. Director General N. Kalaiselvi termed it a paradigm shift from petro-based to bio-based materials, reinforcing the role of public R&D in enabling industrial transformation.

With participation from ministries, scientists, industry stakeholders, and policymakers, the event underscored the intent to move quickly towards commercialisation and deployment.

A circular pathway for India’s road sector

Beyond its technical merits, bio-bitumen represents a broader structural shift in India’s infrastructure narrative—where waste streams are integrated into core industrial applications.

If scaled effectively, the innovation could reshape procurement patterns in road construction, reduce import dependence, and create a new demand stream for agricultural residues—bringing circular economy principles into one of the country’s largest infrastructure sectors.
