, it will lead to 3. Biofuels are obtained directly from naturally available sources by biological pathways such as through carbon fixation, photosynthesis from plants. Major sources of biofuel include alga, corn, cellulose, soy, sugarcane, etc., cellulose should be converted into sugar in order to use as biofuel. Corn oil will be extracted from ethanol and can be fed to animals. By transesterification process, soy can be produced by squeezing it from soy seeds and can be used as jet fuel. Sugarcane is the most commonly used biofuel since it will be obtained in huge quantities rather than biofuel obtained from soy or corn. Advantages of biofuel include cost effectiveness, as biofuel requires natural bio sources, and because of that, it will not cause pollution and will reduce the threat of green house gases. Disadvantage of biofuel include, although it utilises cost effective sources, that itself will lead to increase in price rate in sources like sugarcane, corn, etc.,
