This study was conducted on optimization of
biogas from fresh cassava peels and fresh cow dung
using sodium hydroxide (NaOH). The possibility of
producing biogas from fresh cassava peels and fresh cow
dung waste was investigated. Fresh cassava peel and
fresh cow dung was used in the study. The feed stocks
fresh cassava peels, fresh cow dung and fresh cassava
peel mixed with fresh cow dung were charged into the
bio-digester and used to investigate the anaerobic
digestion in generating biogas for 20days retention
period. The digesters were charged separately with these
wastes in the ratio of 1:2, 1:3 and 1:3 of waste to water
respectively. Pretreatment chemical, (NaOH) solution
was used in pre-treating the fresh cassava peel and fresh
cow dung slurry. The volume of biogas produced were
monitored and recorded daily. The result obtained from
the biogas production showed that fresh cow dung
produced the highest methane content of 67.9 percent,
followed by the mixture of fresh cassava peel and fresh
cow dung with 59.7 percent methane content and fresh
cassava peels has the least methane content of 51.4
percent. The results also showed that the cow dung also
had the highest cumulative biogas yield of 93.3litres,
followed by the mixture of cassava peel and cow dung
with cumulative volume of 73.8litres and the least was
cassava peels with cumulative volume of 61.3litres within
the same retention period of 20days. Overall results
indicate that these wastes which are always available
could be source of renewable natural gas if properly
treated.
