Crop Waste Converted to Bio-Butamen Can Save Around Rs 40,000 cr Annually

India’s Minister for Science & Technology, Dr Jitendra Singh, today said that crop waste converted to bio-butamen can save around Rs 40,000 crores in imports annually for India.

This has been made possible by the use of indigenous bio-bitumen technology developed by CSIR–Central Road Research Institute (CRRI), New Delhi, and CSIR–Indian Institute of Petroleum (IIP), Dehradun, he added.

The Minister said that even partial substitution of conventional bitumen with bio-bitumen will significantly cut import dependence, strengthen economic resilience, and ensure that infrastructure development remains insulated from global supply disruptions.

Dr Jitendra Singh was addressing a Technology Transfer event organised by the Council of Scientific and Industrial Research (CSIR) for large-scale industry adoption of the indigenously developed “Bio-Bitumen from Lignocellulosic Biomass” technology.

The event was also graced by the Minister for Agriculture & Farmers Welfare, Mr Shivraj Singh Chouhan, along with the Director General, CSIR & Secretary, DSIR, Dr N. Kalaiselvi, senior officials, scientists, industry representatives, and stakeholders.

Dr Jitendra Singh described the initiative as a transformative step that converts a major environmental challenge into a national economic opportunity. He said that India produces nearly 600 million tonnes of crop waste annually, much of which is burnt, leading to severe air pollution.

At the same time, India consumes about 88 lakh tonnes of bitumen every year, nearly 50–58% of which is imported at a cost of ₹25,000–30,000 crore. He said this technology bridges both challenges simultaneously by converting agricultural waste into a valuable resource for road construction.

Calling it a true example of Waste to Wealth, Dr Jitendra Singh said that the concept of waste is rapidly becoming irrelevant in a modern, innovation-driven economy.

“There is no such thing as waste; every resource has value if harnessed through science and technology,” he said, adding that agricultural residue like paddy straw can now become a source of income for farmers instead of a cause of pollution.

The Minister said the initiative reflects the vision of Prime Minister Narendra Modi, who had emphasised self-reliance and reduction in import dependence as early as 2014.

He said India’s preparedness during the COVID pandemic, including indigenous vaccine development and seamless Direct Benefit Transfer systems, demonstrated how early policy direction translates into national strength during crises.

He added that similar foresight is now driving India’s transition towards sustainable, low-carbon infrastructure.

Highlighting the multi-dimensional impact of the technology, Dr Jitendra Singh said it delivers on multiple national priorities simultaneously, reducing pollution from stubble burning, lowering import bills, supporting farmers with additional income, promoting the circular economy, and advancing India’s net-zero commitments.

He also pointed out that the success of this initiative reflects strong convergence between ministries, institutions, and industry, demonstrating the government’s approach of breaking silos and fostering public-private partnerships.

Referring to parallel innovations, the Minister cited examples such as converting used cooking oil into biofuel and utilising industrial waste, such as steel slag, in road construction, noting that these efforts are creating a new economic ecosystem in which waste materials are monetised.

He added that incentivising farmers to use crop residue rather than burning it could be a game-changing step in tackling air pollution.

Emphasising the importance of outreach, Dr Jitendra Singh said scientific innovations must be communicated to stakeholders in formats they easily understand, particularly through digital platforms.

He noted that initiatives like “One Week One Lab” have played a key role in connecting scientific institutions with industry, farmers, and the public.

India’s Agriculture Minister Shivraj Singh Chouhan described the initiative as a historic convergence of agriculture, science, and industry.

The Agriculture Minister said the technology provides a practical, scalable solution to stubble burning while increasing farmers’ incomes and reducing environmental damage.

He added that, in the current global scenario, self-reliance in critical sectors such as infrastructure is essential, and innovations like bio-bitumen will play a crucial role in achieving that goal.

Director General, CSIR & Secretary, DSIR, Dr N. Kalaiselvi highlighted the rapid pace of technology adoption, stating that within a short span, multiple industries have already adopted it, with production and field implementation underway.

She said the technology marks a paradigm shift from petro-based binders to sustainable bio-based alternatives. She further noted that the same agricultural biomass can also be utilised for applications such as pest management, advanced carbon materials, and energy storage, demonstrating its wide industrial potential.

The bio-bitumen technology utilises agricultural biomass such as rice straw, wheat straw, and other crop residues as feedstock through a thermochemical (pyrolysis) process to produce a renewable binder.

It can replace up to 30% of conventional bitumen without compromising performance and has demonstrated enhanced durability along with significantly lower carbon emissions.

The technology has already seen successful trial applications, including road construction, and is now moving towards large-scale deployment.

CSIR officials said the organisation will continue to work closely with industry partners, the Ministry of Road Transport & Highways, and other stakeholders for standardisation, field validation, and capacity building to enable nationwide adoption.

Positioning India at the forefront of sustainable infrastructure innovation, the initiative is expected to transform road construction practices by making them greener, more cost-effective, and future-ready, while contributing to the larger vision of Atmanirbhar Bharat and Viksit Bharat 2047.
