Combustion of the fossil fuels at the current rate would
contribute to the environmental crisis globally (Chandel et
al., 2007). The increase in demand of fossil fuels
combined with depletion of this reserves mineral oil has
led to the development of eco-friendly concepts
(Demirbas and Demirbas, 2007). In addition, demand of
the energy increases with the increase of the world
population and urbanization (Demirbas, 2008) and thus,
development of bioenergy as alternative energy might
help to reduce these problems.
