There of ethanol like corn into small

There
is different classification of Biofuels which are the first-generation
biofuels, second generation biofuels, third generation biofuels and fourth
generation biofuels. In this research this study will focus on first generation
which are usually produce by a plants or organic matter. First generation
biofuels use a simple process, the common first-generation biofuel is ethanol
by the process of fermentation. Process Improvement (as cited in United Nation,
2008) Ethanol is being fermented from various source of starch this includes
corn, wheat, grain and etc. It is produce by smashing the certain source of
ethanol like corn into small particles and then water is added with the enzymes
to convert it for the fermentation. Yeast was added to the mashed so that the
fermentation creates ethanol. After the completion of the fermentation during
the process of heating the ethanol will evaporates while the remaining corn and
yeast remains. The ethanol vapors are condensed into a liquid by the
distillation the ethanol is being separate from the raw materials that was
being fermented (University of Illinois, 2009) The properties of ethanol is the
appearance of odor taste, solubility ethanol is much soluble in the water and organic
solvents, density pure ethanol is neutral, boiling point, melting point,
freezing point, flash point.. (“Alcohol (Ethanol) Chemical and Physical
Properties”, 2016) The researcher will use the waste of Gourd, Mango and Citrus
Aurantium Linn, because these are the common waste that people can find in
everywhere such as market and outside of the malls who sell different fruits
aside from that it is also affordable. Those waste in market can be useful if
the people are aware that it can be useful in a way of producing ethanol fuel.
