Abstract: Bangladesh, with poultry farms number of 215000 and poultry population of 200 million, has a potential of 1.33TWhr electricity per year. Despite of this huge potential, only few number of biogas plants have been deployed till date. Besides, most of these plants are unable to produce the expected amount of biogas as most of the digesters of these plants are made locally and they don’t have any scheme for monitoring and controlling temperature, pH, bacterial population in digester, mixture of different substrate, hydraulic retention time, total solid (TS), periodic agitation, periodic loading and unloading of substrate etc. But, there is few bigger size plants which contain imported digesters equipped with monitoring and controlling schemes, hence they produce bigger amount of biogas. In this study, an analysis has been done focusing the impacts of above mentioned factors on biogas production by comparing biogas production between locally made digesters and imported digesters. The result reveals that up to 75% more biogas is generated in imported digesters than the locally made digesters.
