Sweet sorghum, with high photosynthetic efficiency, tolerant to drought and salinity,
is rich in sugar and high in biomass which makes it suitable for bioethanol production.
However, sweet sorghum is not available throughout the year and stalk can be stored for short
period due to high sugar and high moisture content upon harvest. Drying process is known to
prolong shelf life of commodity. The drying behaviour of sweet sorghum stalks was determined
and ethanol production from sweet sorghum stalks was evaluated. In determining the drying
behaviour of the stalks, the predicted shortest drying time using Page equation was 7.99 hours
with samples cut into 1-cm chips. The maximum ethanol production was recovered from fresh
10-cm cut samples with cellulase at 221.92 ml per kg dry mass while 168.24 ml of ethanol per
kg dry mass was recovered from dried 10-cm stalks. Employing dried and fresh stalk samples
for fermentation was proven to be feasible. The fermentation process can be further improved
by sugar extraction through agitation and addition of cellulase.
