2G Ethanol

What is Second Generation (2G) Ethanol?

Second Generation (2G) differs from 1st generation ethanol in terms of feedstock and subsequently, the production process. Second Generation (2G) feed stocks include agri-residues like rice & wheat straw, cane trash, corn cobs & stover, cotton stalk, bagasse, Empty Fruit bunches (EFB), etc.

“Enfinity” – Praj’s Second generation (2G) cellulosic ethanol technology

Our technology brings infinite possibilities to protect the environment and address energy challenges, confronting mankind… by making use of nature’s endless resources. That’s why we proudly call it….Enfinity.
From 1st generation to Second Generation (2G) ethanol technology, we thrive on challenges. We have 1000++ References in 100+ countries across all 5 continents across the globe. Each of these plants carry our signature of technology innovation and integration, delivering lower water and energy footprint.
This knowledge helped us in developing the Second generation (2G) cellulosic ethanol technology “Enfinity”
Praj’s state of the art second generation ethanol pilot plant facility is operational since 2009. This facility has tested more than 450 MT of biomass such as corn cob, cane bagasse, corn Stover, Empty fruit bunches (EFB), Rice straw, etc. Rigorous testing and 8,00,000 man-hours of technology development efforts enabled us to scale the “Enfinity” to 1 Mln litres per annum capacity PRAJ’s End–to-end 2G “Smart Bio refinery” solution based on “Enfinity” technology: The Smart Bio refinery will process multiple feed stocks and shall produce multiple products like bio ethanol, bio butanol, bio chemicals, power, Bio CNG, CO2 etc.
