Globally, bioethanol production fro

Globally, bioethanol production from rice straw,
wheat straw, corn straw and sugarcane bagasse is Due to rapid growth in population and
industrialization, worldwide ethanol demand is
increasing continuously. Conventional crops such
as corn and sugarcane are unable to meet the
global demand of bioethanol production due to
their primary value of food and feed. Therefore,
lignocellulosic substances such as agricultural
wastes are attractive feed stocks for bioethanol
production. Agricultural wastes are cost effective,
renewable and abundant. Bioethanol from
agricultural waste could be a promising technology
though the process has several challenges and
limitations such as biomass transport and
handling, and efficient pretreatment methods for
total delignification of lignocellulosic. Proper
pretreatment methods can increase
concentrations of fermentable sugars after
enzymatic saccharification, thereby improving the
efficiency of the whole process. Conversion of
glucose as well as xylose to ethanol needs some
new fermentation technologies, to make the
whole process cost effective. In this review,
available technologies for bioethanol production
from agricultural wastes are discussed.
