ABSTRACT
Bioethanol
is a renewable and alcohol-based fuel derived from various biological sources.
It is primarily produced through the fermentation of sugars found in crops such
as corn, sugarcane, wheat and other agricultural products. The process involves
the conversion of these sugars into ethanol by yeast or bacteria. Bioethanol is
widely used as a biofuel additive in gasoline, aiming to reduce greenhouse gas
emissions and dependence on fossil fuels. It is considered a cleaner
alternative as it produces fewer emissions when burned compared to traditional
gasoline. Moreover, it can be blended with gasoline in different ratios (such
as E10 or E30) and flexible fuel vehicles are designed to use these blends
interchangeably. There is a global interest in replacing fossil fuels with renewable
sources of energy. Energy from fossil fuels has played a vital role in our
lives, but the hazards it gives rise to cannot be ignored, thus there is a need
for an alternative source of energy that is environmentally friendly and not
harmful to human lives. This research is based on the production of bioethanol
as an alternative source of fuel using rice husk, cassava peels and yam peels
as raw materials. The bioethanol was produced by fermentation of rice husk,
cassava and yam peels with the aid of Saccharomyces
cerevisae at different time
intervals of 48hours, 72hours and 96hours. The fermented liquid was distilled
at 78⁰C
and the yield of bioethanol was determined. The use of various concentrations
of H2SO4 for hydrolysis of the agricultural wastes, yeast for fermentation and at
different retention times of 500g of cassava peel, yam peel and rice husk
yielded a peak mass of 6.46g, 5.58g and 3.19g respectively. This study shows
that bioethanol can be produced from rice husk, cassava and yam peels with
maximum yield from cassava peels as a result of the presence of higher starch
content when a higher quantity of yeast was used.
