Egypt is facing a shortage of traditional fuels. Poultry farms consume a huge amount of liquefied petroleum gas (LPG) cylinders for heating purpose in winter, which affects the needs of the domestic sector. Poultry Manure is difficult to dispose and its accumulation causes spreading of harmful insects and pests which leading to the dissemination of various diseases that are transmitted to humans and animals and pose a threat to public health. While poultry wastes can be anaerobically fermented to produce biogas to make self-sufficiency of methane. Poultry manure (PM) contains high percentage of nitrogen though it must be co-digested with other substrates to adjust carbon nitrogen ratio to produce biogas with high quality and high percentage of methane. Poultry manure is co-digested with Banana Peels (BP). A simple setup was used to digest the mixed substrate PM /BP with different ratios. PM /BP mixtures at different ratios -5 mixtures- were digested. Mixtures are as follows BP and PM was mixed at ratios 1-3, 1-1, 3-1 respectively in addition to BP and PM only. Five digesters were used to carry out experiments. Biogas was collected and measured daily. The studied parameters were pH, C/N ratio, biogas yield, and methane content. The best co-substrates with the highest percentage of methane content and highest amount of biogas produced are 50% BP+50%PM.
