|Abstract: ||Pongamia pinnata is one of the promising tree species suitable for providing oil for biodiesel production. This
paper addresses the life cycle energy balance, global warming potential and acidification potential, of a small scale biodiesel
system, in rural Karnataka.
In addition, the system has also been expanded to generation and use of biogas from seed cake for
electricity production and evaluated for its environmental impacts.
The environmental impacts have been benchmarked with
the life cycle impacts of fossil diesel. The results show that non-renewable energy requirement of Pongamia biodiesel system
is twenty-eight times lower than that of fossil diesel.
A significant increase in global warming potential (GWP) is indicated in
Pongamia biodiesel system compared to fossil diesel if wood is used as fuel.
GWP would be seven times less if wood is not
used as fuel. Acidification and eutrophication potential of Pongamia system was found to be nil.
Further, expanding the
Pongamia biodiesel system to include biogas production exploits the energy available in the system. It is also observed that
one hectare of Pongamia plantation is capable of completely sequestering the CO2 released during the life cycle with additional
sequestration potential up to 1 t CO2 ha-1. Moreover, the above aspects were significantly superior in Pongamia system when
compared to Jatropha biodiesel system.|
