New Delhi, April 1 (IANS) India has taken a major step toward greener infrastructure with the development of a new technology that turns crop waste into bio-bitumen, a key material used in road construction, a report has said.

This innovation, created by scientists from the Council of Scientific and Industrial Research (CSIR), could help the country reduce its dependence on imported petroleum-based bitumen while also tackling the long-standing problem of stubble burning, according to Devdiscourse report.

Union Minister Dr. Jitendra Singh recently highlighted the importance of this breakthrough, explaining that crop residues such as rice straw can now be converted into a useful binding material through a process called pyrolysis.

This process heats biomass in the absence of oxygen to produce a renewable and eco-friendly alternative to traditional bitumen. Early trials of the technology have shown promising results, raising hopes for its large-scale use in road construction.

The innovation comes at a time when stubble burning continues to cause severe air pollution in many parts of India. By giving farmers a practical use for agricultural waste, the new method could significantly reduce the need to burn leftover crop material, leading to cleaner air and better environmental outcomes.

CSIR Director General N Kalaiselvi noted that industries are already showing interest in adopting this technology. Efforts are underway to transfer the technology to companies so it can be used on a larger scale.

Beyond road construction, the process may also open doors to other applications, including pest control solutions and advanced carbon-based materials, the report stated.

Experts said that the development of bio-bitumen represents a win-win solution for India. It not only supports sustainable infrastructure growth but also helps farmers, reduces pollution, and strengthens the country’s economic resilience in the face of global supply challenges.
