Bioethanol
-Ethanol can be made by fermentation.
-Fermentation is the process of using yeast to convert the sugar into ethanol.
-Carbon dioxide is always produced.
-The fermented mixture can be distilled to produce more concentrated biogas.
-Bioethanol is quite cheap to produce.
-Ethanol can be used as a fuel, it only gives just carbon-neutral carbon dioxide and water.
Advantages: Crops grown for bioethanol production take-in water, carbon di oxide from the atmosphere. This goes some way toward bioethanol carbon dioxide and water.
Disadvantages: The price of crops can increase growing plants for the production of bioethanol may mean that land
-Bio-fuels-what are they and where they come from?
-Biofuel is fuel made from the living organisms or a by-product of waste, and vegetable oil.

Releases less pollution than ordinary diesel.
Disadvantages: We can't make enough. Biodiesel is Toxic
