"The expansion will help our greater participation in the government's ethanol blending programme that mandates 5 per cent blending of bio-fuel with petrol," the company's Chairman and Managing Director Samir Somaiya said in a statement.
With this expansion, the company has the capacity to make 50 million litres per year of fuel grade ethanol, up from 15 million litres, at present.
The expansion of the fully automated plant using molecular sieve dehydration technology was completed in five months. The facility will use byproducts of their sugar manufacturing process as raw material, it said.
GBL produces sugar, biofuels, chemicals, power, compost, waxes and related products using sugarcane as the primary feedstock. It has two manufacturing units in Karnataka and Maharasthra.
