CLEAN ENERGY
Students have been actively involved in this
project of active citizenship about environmental
sustenaiblity.
They have become aware that everyone can
contribute to solve the heavy pollution problems
of Taranto
oil and natural gas prices
remain high and volatile
across the globe
clean energy is an opportunity
to address air pollution,
public health problems,
greenhouse gases, and grid
congestion
The price of fuel is rising up and traffic
congestion has become a compelling
problem
It is necessary to use green fuel.such
as biodisel and bioalcol
Biodisel offers competitive low cost
prices and is clean energy

MAIN OBJECTIVES :
•To know the main energry
resources with specific
attention to the sun
•To know the avilability of
biomass in our territory
•To project and install solar
pannels on the roof of our
school
•To produce biodiesel in our
chemicl laboratories
BIODIESEL
• Biodiesel is a domestic, renewable fuel for diesel
engines derived from natural oils like soybean oil, and
which meets the specifications of ASTM D 6751.
• Biodiesel is commonly produced by the
transesterification of the vegetable oil or animal fat
feedstock
• There are several methods for carrying out this
transesterification reaction including the common batch
process, supercritical processes, ultrasonic methods,
and even microwave methods.
• Biodiesel can also be used as a heating fuel in domestic
and commercial boilers, sometimes known as bioheat.
• Chemically, transesterified biodiesel comprises a
mix of mono-alkyl esters of long chain fatty acids
• Using alcohols of higher molecular weights
( Methanol)improves the cold flow properties of the
resulting ester.

Chemical characteristics of biodisel
for heating
Advantages
• Biodegradable at 95%
• Atossic
• May be obtained by vegetable oils such as
fried oil DLgs 05//02/ 1977 , n° 22.
• Its production is ecologic
