In Fiji, biogas has a huge potential to be one of the energy providers for cooking in rural areas but currently its use is very minimal. Main component of biogas is methane which releases energy when combusted. This paper mainly presents the factors that affect biogas production using experimental study. The first section presents an overview on what is biogas, types of biogas digesters present, and some background on the current use of biogas in Fiji. The second section of the paper describes the methodology in brief of the experimental work carried out. The third section of the paper presents results that were achieved in the experiment, discussion, and interpretation of the results and how Fiji could benefit from this study. It was evident that cow + Pig mix manure produces high rate of biogas at mesophilic temperature and cow dung manure is best for biogas production at room temperature.
