Variation of biogas production with different factors in poultry farms of Bangladesh

摘要

In Bangladesh, biogas has a huge potential with it's over 200000 poultry and about 200 million of poultry birds. Contrary to the immense potential of producing 1.33TWhr electricity per year from poultry industry, only few number of biogas plants have been deployed in some farms till date. Besides, most of these plants are unable to produce the expected amount of biogas for their technical shortcomings. Most of these plants run by locally made equipment and don't have any scheme for controlling the significant factors of biogas production. However, there are few bigger sized plants consisting imported digesters, monitoring and controlling systems which yield larger amount of biogas production. In this study the impacts of some major factors on biogas production was analysed 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.
