 Hindustan Petroleum Corporation Limited (HPCL) is involved in several bioethanol-related activities, including: 

Research

HPCL's Green R&D Centre in Bengaluru conducts research on biofuels, including ethanol-gasoline blends. Preliminary studies have shown that these blends can significantly reduce emissions and net CO2 emissions. 

Ethanol production

HPCL Biofuels Ltd. manufactures fuel grade ethanol that can be blended with petrol. The ethanol plants use technologies such as continuous fermentation, multi pressure distillation, and molecule sieve technologies. 

Bio-refinery

HPCL owns a bio-refinery in Bathinda that produces ethanol from paddy straw. The plant is designed to produce 100 Kilo Litre (KL) of ethanol per day. The plant's operation is expected to significantly reduce paddy straw burning in the region. 

E27 fuel

HPCL launched a pilot study on E27 fuel, which is a blend of 27% ethanol and fossil-

based fuel.
