Cassava tuber was obtained from a farm in Nnewi Nigeria,
peeled and washed with water. After washing, the tuber was
weighed and the wet weight obtained as 1393 g. The tuber was
grated, slurried in water and
filtered using muslin cloth spread on a
locally made sieve. Slurrying and
filtration were repeated several
times until the residue was deemed ready for disposal. This residue
was now used for our research as it was sundried, ground to a
fine
powder and weighed 96.5 g. This process was used as it is a
common practice in Nigeria for Garri processing [17]. When this is
done, little do they know that the supposedly cassava waste can be
applied for bioethanol production
