Bioethanol is a form of renewable energy that can
be produced from agricultural feedstocks.
Bioethanol is an alcohol made by fermentation,
mostly from carbohydrates produced in sugar or
starch crops such as corn, sugarcane, or sweet
used as a petrol substitute for road transport
4. Comes with The Ideas
Bioethanol Bioethanol is one of the
alternative fuels that have
advantage than fossil fuel
Bioethanol used plants as the raw material, so
it does not make accumulation of carbon in
the atmosphere Ethanol can also increase the
efficiency of combustion because it contains
35% oxygen and environmental friendly
because dump of gas emissions such as
carbon monoxide, nitrogen oxides, and other
gases are low (19-25%) o
How we make
it? During this time, bioethanol was produced
from molasses (sugar production process
waste) or starchy materials (cassava or corn).
5. But,we face another problem
etc. Source of
Foodfind other sources of raw
polysaccharides and not
be used as food!
6. Meet Bagasse!
Bagasse is an industrial solid waste
from sugar cane containing cellulose
fiber and usually used as a raw
material for the paper industry
Bagasse waste not yet widely used.
This waste is one of the energy
sources potential and generally is a
cellulose material that can be
converted into ethanol
7. tons of bagasse can
each hectares in a year
Bagasse in Numbers

Tons in a year
12. Advantages Disadvantages
Ethanol is a renewable resource Large amounts leading to problems
such as soil erosion, deforestation.
Ethanol burns more cleanly in air than
Typical current engines would require
The use of ethanol reduce carbon
ADVANTAGES & DISADVANTAGES
Bangladesh annually imports about 3.5 million tons of different fuel
Bioethanol is the most potential renewable energy source to mitigate
this energy crisis.

Notes de l'éditeur
The hydrolysis of polysaccharides to soluble sugars is called "saccharification".
Distillation-action of purifying a liquid by a process of heating and cooling. Pretreatment- hot water + steam
