Abstract
In this study, it was observed that in experimental
work under laboratory scale using conventional biochemical
methane potential (BMP) assay, the loading rate ratio 4:1 had
optimum biodegradability rate than other ratios which were
investigated, while the loading rate ratio of 1:1 had optimum
biogas and methane yield after 15 days hydraulic retention
time. It was concluded that chicken waste (CM) monodigestion
has higher biodegradability rate compare to organic
fraction municipality solid waste (OFMSW) mono-digestion.
Co-digestion of OFMSW and CM stabilizes conditions in
digestion process such as carbon to nitrogen (C:N) ratio in the
substrate mixtures as well as macro and micronutrients, pH,
inhibitors or toxic compounds, dry matter and thus increasing
biogas production. It was concluded that the organic waste
generated in the municipal landfills could be co-digested with
CM to produce methane which can be used as a source of
environmentally friendly and clean energy for the transport
sector, industries and residential homes.
