Conclusion
The overall results indicate that the low biogas yield and
slow onset of gas production / flammability of digested
cassava peels can be enhanced significantly when combined
with animal wastes. The blend with cow dung and
poultry droppings had the fastest onset of gas flammability
while that with swine dung had the highest cumulative
volume of gas production. Hence, cassava peels which is
considered a nuisance can be converted to a useful source
of energy by combining it with these or any other animal
wastes. Investigation of other ratios will constitute a
separate report.
