The study explored the production of biogas from Lemon grass, Cow dung and Poultry droppings. The
three substrates were pre-fermented according to standard methods. Six (6) kg of each pre-fermented
substrate was mixed with water in ratio 1:1 v/v to form slurry and digested for 30 days. A total of
0.125 m3
, 0.191 m3 and 0.211 m3 of biogas were respectively produced from the Lemon grass, Cow dung
and Poultry droppings with deviations of 0.00234 m3
, 0.00289 m3 and 0.00484 m3 respectively. The cooking
test carried out revealed that the scrubbed gas had higher cooking rates for water (0.12 L/min,
0.085 L/min and 0.079 L/min for Lemon grass, Cow dung and Poultry droppings respectively) while the
cooking rates for unscrubbed gas were 0.079 L/min, 0.064 L/min and 0.06 L/min respectively. The pH of
the medium fluctuated optimally between 6.5 and 7.8. The research demonstrated that Lemon grass produced
less volume but better quality biogas compared to Cow dung and Poultry droppings.
