2. Objectives
• To produce bioethanol from different vegetable sources(Sweet
potato, Manioc, Sugar cane, Beetroot) using fermentation process
by yeast.
• To compare the ethanol percentage produced from different
sources by using ebulliometer.

10. Limitations
• Not as efficient as petroleum.
• Typical current engines would require
modifications.
• Food vs. fuel debate.
• Large amounts leading to problems such as soil
erosion and deforestation.
