Nibedita et al (2012) [18] classified four major agro
wastes as the most favorable feed stocks for
bioethanol production due to their availability
throughout the year. Worldwide production of
these agro wastes is given in Table 2. Asia is the
major producer of rice straw and wheat straw,
whereas corn straw and bagasse are mostly
produced in America. Lignocellulosic materials are
renewable, low cost and are abundantly available.
It includes crop residues, grasses, sawdust, wood
chips, etc. Extensive research has been carried out
on ethanol production from lignocellulosic in the
past two decades.
