India Launches First Bio-Bitumen Highway Stretch

India has recently inaugurated its first bio-bitumen-based National Highway stretch on NH-44 in Mansar, Nagpur, Maharashtra, utilizes lignin-based bio-bitumen technology, developed through collaborative efforts involving Praj Industries, CSIR-CRRI, NHAI, and Oriental.

What is Bio-Bitumen?

Bio-bitumen is a sustainable alternative to traditional bitumen. It is derived from lignin, a natural polymer found in plant cell walls. This material serves as a binder, providing similar properties to conventional bitumen but with ly lower environmental impact.

Importance of Lignin

Lignin is abundant in agricultural waste and is a renewable resource. By using lignin, this project addresses the shortage of traditional bitumen, which currently sees 50% of its supply imported into India. The shift to bio-bitumen reduces dependency on imports and promotes local production.

Environmental Benefits

The use of bio-bitumen contributes to global sustainability goals. It is estimated to cut greenhouse gas emissions by at least 70% compared to fossil-based alternatives. Additionally, this initiative prevents stubble burning, which is contributor to air pollution.

This project aligns with India’s vision for Aatmanirbhar Bharat, promoting self-reliance and large-scale domestic production. The initiative not only supports the economy but also generates revenue for bio-refineries, contributing to sustainable development.

CNG Production from Biomass

Union Minister Nitin Gadkari announced 400 projects aimed at producing CNG from biomass, with 40 already completed. These projects have utilised 60 lakh tonnes of stubble, offering a cleaner fuel alternative while reducing pollution from stubble burning.

Gadkari brought into light that farmers will transition from mere food producers to energy and resource providers. By converting agricultural waste into valuable bio-bitumen, farmers can contribute to India’s sustainable future.

GKToday Notes:

1. Bio-Bitumen: Bio-bitumen is a sustainable alternative derived from lignin. It reduces environmental impact while providing similar properties to traditional bitumen. This innovation promotes local production and reduces import dependence.
2. Lignin: Lignin is a natural polymer found in plant cell walls. It is abundant in agricultural waste and serves as a renewable resource. Its use in bio-bitumen addresses traditional bitumen shortages.
3. Aatmanirbhar Bharat: Aatmanirbhar Bharat translates to “self-reliant India.” This initiative promotes local production and economic independence. It aims to reduce reliance on imports while encouraging sustainable growth in various sectors.
4. CNG from Biomass: CNG production from biomass involves converting agricultural waste into cleaner fuel. With 400 projects planned, this initiative reduces pollution and provides a sustainable energy alternative for India.
