2nd Generation Ethanol

What is 2nd generation ethanol

2nd generation ethanol differs from 1st generation ethanol in terms of feedstock and subsequently, the production process. 2nd generation feedstocks include agri-residues like rice & wheat straw, cane trash, corn cobs & stover, cotton stalk, bagasse etc.

In India, these items are usually burnt for household cooking leading to pollution and do not fetch any considerable value to the farming community.

Why 2[sup]nd[/sup] generation ethanol

Today more than60 countries have mandates or targets to blend ethanol with gasoline, which include 14 countries in the Americas, EU 27, 10 countries in Asia-Pac, 10 countries in Africa and Indian ocean and 2 countries from non-EU Europe.

India has joined these countries with ethanol blending program catching tremendous momentum in the last two years. Ethanol assumes significant importance in the global energy matrix and makes all the more sense for a country like ours developing at a fast pace.

Directly linked to vehicle ownership and increasing income levels, petrol is the fastest growing fuel segment in India. Assuming a growth rate of 8% per annum, petrol consumption is expected to rise to 41 bnliter by 2022. To achieve the aspired 20% blend ratio at this level, 8.2 bnliter ethanol would be required.

Transport sector is the 2nd largest contributor to GHG emissions, after industry and the easiest to target. With our commitment to reduce emission intensity of GDP by 33-35% by 2030 from 2005 levels according to Intended Nationally Determined Contribution at COP 22, it is imperative to blend ethanol with petrol.

Praj’s 2[sup]nd[/sup] generation ethanol technology

With the development of 2nd gen ethanol technology, Praj is on the mission to change the face of renewable energy in India’s transport sector and is the frontrunner in setting up multiple 2nd generation ethanol plants in India. Our indigenously developed 2nd generation cellulosic ethanol technology has achieved an important milestone with successful completion and start-up of 1mnliter per annum Integrated "Smart Bio-refinery" Demonstration plant in Maharashtra, India. This is country’s first bio-refinery, capable of processing multiple agri-residue like rice & wheat straw cane trash, cotton stalk, bagasse etc and is equipped with a zero liquid discharge system. It is a matter of pride that the team completed this significant feat within the stipulated time and budget. The bio-refinery was inaugurated at the hands of Mr Nitin Gadkari, Union Minister Road Transport, Highways and Shipping on 7th May, 2017. With continual research & development, further pipeline of biofuels and chemicals is underway to be produced from the same technology platform.

Praj has been chosen by the leading oil marketing companies (OMCs) as technology partner for their 2nd generation ethanol projects in India. This technology has the potential to diversify agricultural sector to produce food, energy, power, everyday use chemicals from renewable sources. This will generate rural employment while striking the right balance between development and environment and lead the country to greater energy self–reliance.

At every step, Praj strives to be true its vision of making the world a better place. With technology already on its way to deliver clean fuel, it marks a milestone in the biofuel economy of India.
