Abstract:
Bagasse and Poultry droppings are common wastes
in some Nigerian towns that pollute the environment and may be
causing health problems. This investigation utilized bagasse and
poultry droppings, both separately and as blends, to generate
biofuel while the biogas yield and quality were monitored. The
feedstocks were subjected to anaerobic digestion for 35 days at
mesophilic temperature. Biogas yield was progressively higher in
the blends as poultry droppings proportion grew higher and was
highest with poultry droppings alone. Bagasse alone as a
feedstock produced the least volume of biogas. Onset of gas
flammability was observed on the 4th day for bagasse
and poultry droppings blends while for poultry droppings alone,
it was observed on the 5th day. Bagasse alone
produced higher methane component of the biogas compared to the
percentage methane content in the biogas produced from bagasse
blends with poultry droppings. This work showed that biogas of
high methane content was produced from wastes that were
environmental pollutants by applying appropriate process
parameters.
