Biodiesel can be produced by any oil but Karnataka Biofuel Policy restricts it to non-edible oil and waste oil. More than 150 species of non-edible oil yielding species have been identified by Karnataka State Biofuel Development Board ( KSBDB), most of which are region specific. The non- edible oil seed species that are grown in Udupi and the coastal region are Rubber seed, Honne (Calophyllum inophyllum), Nagachampa, Amura, Shanti (Terminalia bellerica), Naikuli or Buguri (Sclerophyllum pentadrum) and many more. These seeds are already available in large quantities in coastal region and are having no or minimal commercial application. These seeds are potential feed stock for biodiesel production. Aforementioned seeds are purchased from farmers for a reasonable price.



Karnataka State Biofuel Development Board (KSBDB), Bengaluru sponsored the establishment of the Biofuel Information and Demonstration Centre in the premises of NMAMIT at Nitte and is run by the Department of Biotechnology Engineering. This centre is the Udupi district BIDC.

This centre is one among the 32 Information and Demonstration Centres instituted by KSBDB in Karnataka.


Inauguration of UBIDC at Nitte

Udupi district BIDC is responsible for production of biodiesel from various non-edible oil seeds available in Udupi district, create awareness, disseminate information about biofuels amongst the scientific community, students, farmers and public and give demonstration, and provide technical know-how about biodiesel production. The objectives of BIDC also include developing plantation of local breeds of biofuel plants, conduct research on biofuel processes and also involving NGOs in the awareness programs. The byproducts of biodiesel production such  as  cake  and  glycerol  havcommercial application. Oil cake can be used as manure in the farm, whereas some oil cakes (non-toxic) can be used as cattle feed. Glycerol is used in soap making. Production of biodiesel from locally available non-edible oil seeds and its utilization gives eco-friendly fuel, adds revenue to the farmers, saves foreign exchange, reduces dependence on foreign countries for fuel and improves rural employment. 


The BIDC at Nitte has a capacity of producing 50 liters of biodiesel per batch which requires about 10-12 working hours. Biodiesel is produced through a chemical reaction called as trans-esterification. The oil is first extracted through a mechanical expeller. The oil is then treated with methanol at 60oC in presence of sodium hydroxide. Then produced biodiesel is separated and purified for engine use. UBIDC also houses a testing lab for Biodiesel testing where major 5 parameters (Acid value, Viscosity, Density, Flash point and Copper strip corrosion) are tested. Biodiesel can be used in any diesel engine without modification and biodiesel can be used in blending with mineral diesel. Biodiesel can be used in vehicles, DG sets, tractors, pump sets etc.
