2nd Gen Bio-refinery (1 MLPA) demonstration plant for ethanol & bio-chemicals

Signed contracts with major Indian Petroleum companies of India to set up 10MGPY 2G ethanol plants

Learning from 1G for improved viability

Co-products value addition crucial to viability

• Valorization of the component of feed stock

• Corn

• 2G Ethanol plants in India : 400-500 MTPD biomass producing 100 KLPD (80-100 MTPD) of ethanol

• Lignin production : 70-100 MTPD

In nut-shell: 1 kg ethanol ≈ 1kg lignin

• Current value of lignin as a boiler fuel : $0.05/ kg

• Valorisation of lignin depends on the nature of lignin and cost required for making products for

different applications
