The oils obtained from seeds of several plants and trees like Pongamia (honge), Neem (bevu), Hippe, Simarouba, Red Physic Nut(kaduharalu) that grow abundantly in our country, can be used as an alternative fuel or as biofuel. Also, the oil cake which is a by-product, is an excellent organic manure, the leaves of the trees can be used as green leaves manure. Vehicles like bus, lorry, tractor, car, jeep can be run on this oil without any modification to the engine. This biofuel can be used as an alternative to diesel in machines in industries. Even trains can be run on this oil. The University of Agricultural Sciences of the state (UAS) and Indian Institute of Science (IISc.) are engaged in such research. Karnataka State Road Transport Corporation (KSRTC) is already running 500 buses. Measures are being taken to run 5500 buses phase-wise on the environment-friendly biodiesel in the coming days. This measure is environment-friendly. This action not only benefits transport organizations like the KSRTC and biofuel producers but also paves the way for phase-wise self-sufficiency by saving on foreign exchange and reducing dependence on others.
Different types of value-addition activities of biofuel can be done in rural areas only, this not only increases opportunities for employment creation in rural areas, but it can also fetchmore income for the farmers, fulfil the fuel requirements of the rural area with locally manufactured fuel and the extra fuel can be sold.
Biofuel plants can be grown in the 13.5 hectare barren, waste land in the state, not suitable for agriculture, along river canals, and fence, bunds in the farm lands, and in government and private land. Biofuel plants can be easily grown in the plains and in areas with scanty rainfall. Environment pollution can be prevented along with afforestation. In addition to providing excellent organic manure, a strong foundation can be laid for providing a safe fuel for the nation and for ensuring the nation’s fuel security.
