Union Minister Nitin Gadkari inaugurated India’s first bio-bitumen-based National Highway stretch on NH-44 in Mansar, Nagpur, Maharashtra. This stretch has been developed using lignin-based bio-bitumen technology by Praj Industries, in collaboration with CSIR-CRRI, NHAI, and Oriental.
The use of lignin as a sustainable binder marks a significant breakthrough in flexible pavement technology, addressing the challenge of bitumen scarcity and reducing India’s dependency on imports, which currently constitute 50% of the total supply.
This innovation contributes to global sustainability goals by generating revenue for bio-refineries, mitigating stubble burning, and reducing greenhouse gas emissions by at least 70% compared to fossil-based bitumen. Leveraging India’s abundant lignocellulosic biomass, this development aligns with the nation’s vision for sustainable industrial growth.
Speaking on the occasion Gadkari emphasized that fostering advancements in green technologies and promoting industrial sustainability aligns with Hon’ble Prime Minister Shri Narendra Modi Ji’s vision of Aatmanirbhar Bharat. He highlighted that this initiative paves the way for large-scale domestic production and a self-reliant, sustainable future for India.
