In the modern fast growing world the issues of global warming
and energy crises are two major challenges [1,2]. The use of fossil
fuel produces various toxic gases which cause environmental
problems. Along with the use of fossil fuels the other main source
of environmental pollution are untreated wastes. The improper
management of wastes from various industries and live stocks has
adverse effects on the environment and economy [3]. The development
of some renewable energy resources which can be produced
from current waste can offer a solution to solve both of these problems
[2,4].
Bio-ethanol is one of the main renewable energy sources which
can contribute to overcome these problems [5]. It has been dubbed,
a future fuel [5]. It can be blended with gasoline to reduce the emission
of CO2, NOx and hydrocarbons after combustion relative to that
of gasoline alone [4]. Ethanol is used as a solvent and is also used in
the production of various organic chemicals and their derivatives
