Today, gradually running out of fossil fuels, the destruction of ecosystems, efforts to avoid being dependant
on foreign countries for energy and to increase energy diversity have increased the importance of fuels such
as bioethanol. Biomass production of bioethanol from sugar beet molasses will lead to open a new market
for beet producers, to widespread the crop rotation, to create an energy farming culture and lead to an
increase in sugar beet growing areas. Bioethanol also contributes favorable support to the ecology by
providing diversity in agricultural production and it is important for creating sustainable agricultural structure
and supporting rural development. Bioethanol in general is obtained by fermentation of plants containing
sugar and starch. Sugar beet molasses is used for the production of bioethanol from sugar beet. Production
of bioethanol from molasses is carried out at three stages such as yeast reproduction, fermentation and
distillation. The alcohol obtained in %96 purity during ethanol production process is not used as biofuel. In
order to be used as biofuel it should be in %99.5 purity. Therefore, in alcohol plants the purification and
distillation units are needed in addition to fermentation unit. Attention should be paid to alternative energy
sources such as bioethanol since the oil reserves are decreasing and environment problems are increasing.
