Snippets of Information - Inventions / Innovations
* 15 Jun 2026
Researchers at IIT Bombay have developed a patented biomass gasification technology
that converts campus waste (dry leaves, twigs, and municipal solid
waste) into clean-burning cooking fuel. This homegrown innovation
drastically cuts reliance on LPG, achieving 60% thermal efficiency while
keeping emissions safely under 20 ppm.
The technology tackles the typical Indian biomass challenge (ash
clinkers and heavy smoke) through a carefully controlled, 4-step
sequence:
Collection & Pelletisation: Fallen leaves and twigs are gathered
from the campus. They are shredded, dried to remove moisture, and
compressed into dense, manageable biomass pellets.
Heating & Pyrolysis: These pellets are fed into a modified downdraft
gasifier. In a low-oxygen chamber, the biomass is heated to high
temperatures, triggering pyrolysis where the solid material releases a
fuel-rich gas.
Gas Cleaning: A patented premix burner system separates the particulate
matter and ash, eliminating the prolonged smoke emission seen in older,
conventional setups.
Combustion: The resulting producer gas (with a calorific value of 3.67
MJ/kg) provides a clean, steady, and smokeless flame perfect for
industrial canteen operations.
