Abstract
Corn stover (CS) has currently received great attention worldwide as a potential feedstock
for the production of bioethanol as alternative renewable fuel or additive to gasoline. This
work evaluates the quantities and chemical characteristics of the CS available in Ghana
and their conversion into bioethanol. The average quantity of CS production in Ghana per
year was estimated to be 1.77 × 106 t. The cellulose, hemicellulose, and lignin contents
of CS obtained from Pioneer 30 W 40, a local maize variety, were found to be 37.72 %,
20.62 %, and 30.50 %, respectively. Alkali pretreatment and enzymatic hydrolysis of the CS
yielded a reducing sugar concentration of 157.96 mg/ml within 24 h and an ethanol yield
of 0.045 l/kg. It was estimated that 40 % of the average annual CS production has the
potential of yielding 140.855 × 106 l of bioethanol.
