April 1, New Delhi: A unique innovation by IIT Bombay is transforming dry leaves into cooking fuel, offering a sustainable solution amidst rising energy costs. The technology has significantly reduced LPG consumption while cutting carbon emissions on campus.
The biomass gasification technology, developed by Professor Sanjay Mahajani and later improved with contributions from Professor Sandeep Kumar, converts dry leaves and organic waste into cooking gas. Initial challenges were addressed with a modified gasifier that reduced clinker formation, making the system operationally viable.
Now implemented in the campus canteen, the system has lowered LPG use by 30–40% and cuts around eight tonnes of carbon emissions annually. The technology has been licensed for wider adoption, offering potential for major cost savings and environmental benefits.
