Praj Industries, a leader in industrial biotechnology, has inaugurated India’s first sustainable road using lignin-based bio-bitumen. The landmark project, situated on the Nagpur-Mansar Bypass (NH 44), was unveiled by Union Minister Nitin Gadkari.
As reported by thehindubusinessline, this innovation marks a milestone in reducing dependence on fossil-derived bitumen and promotes eco-friendly road construction.
Revolutionary Technology Reduces Emissions
Praj’s proprietary technology transforms crude lignin into Lignin Bio-Bitumen, a sustainable alternative to traditional bitumen. Capable of blending up to 15%, this material reduces greenhouse gas emissions by 70%.
India would need approximately 15 lakh tons of bio-bitumen to achieve 15% blending, potentially saving ₹4,000-4,500 crore in foreign exchange annually.
Minister Praises Sustainable Initiative
Nitin Gadkari lauded the initiative, stating that the bio-bitumen, developed in collaboration with CSIR-CRRI, is a step towards sustainability.
He emphasized that this innovation reduces dependency on imported bitumen while converting agricultural waste into a valuable resource. Gadkari envisioned farmers playing a dual role as food and energy providers, contributing to a greener India.
Proven Performance and Collaboration
In partnership with CSIR-CRRI, Praj Industries successfully tested the lignin bio-bitumen on a service road in Halol, Gujarat. After 2.5 years and three monsoon seasons, evaluations confirmed the road’s durability. This success paved the way for the Nagpur-Mansar project.
Strengthening Atmanirbhar Bharat
Dr. Pramod Chaudhari, Founder Chairman of Praj Industries, hailed the project as a testament to India’s commitment to sustainability.
Developed under the ‘Make in India’ initiative, the technology not only replaces fossil-based bitumen but also saves significant foreign exchange, aligning with the vision of Atmanirbhar Bharat.
Addressing Future Demand
India’s bitumen consumption, which stood at 88 lakh tons in 2023-24, is expected to reach 100 lakh tons in 2024-25.
With nearly half of this demand met through imports, costing ₹25,000-30,000 crore annually, sustainable alternatives like lignin bio-bitumen are crucial for achieving the nation’s vision of Viksit Bharat 2047.
