Solution for Sustainable Development of Biodiesel Production through Microalgae

Abstract

Energy plays a vital role in global economy. The use of fossils as energy source
is increasing day by day, however continuous usage of the fossils is hazardous
for the future generations due to the accumulation of greenhouse gases in
the environment. So we must curb the use of fossils for the energy and fuel
production in order to preserve our ecosystem. Another reason is that being
a non-renewable energy source, fossils takes millions of years to renew. To
overcome this problem we should use such type of energy sources that are
renewable and eco-friendly. Renewable and carbon neutral biodiesel are
necessary for environmental and economic sustainability. There is also an
alternative way of production of biodiesel by microalgae as provide sufficient
energy. Demand of biodiesel is constantly increasing as the reservoir of fossil
fuel are depleting. However, the question arises on the viability of first
generation biofuel production due to its conflict with food supply. Microalgal
diesel production appears to be a viable alternative. As a third generation
biofuel, microalgal biodiesel has emerged with an enormous amount of
economic and environmental benefits. It has been noticed recently that
microalgae is the most favorite feedstock for triacylglycerol (TAG), the
storage neutral lipid, for renewable and sustainable biodiesel production, due
to their comparable lipid contents, faster growth rates and lesser land
requirements in comparison to the non-conventional and non-edible oilseed
crops. Many microalgae exceed the productivity of oil of the best producing
oil crops. In this article the method applied of biodiesel production has been
implemented in such a way to increase its production.
