Abstract

This study demonstrates the feasibility of biogas production from poultry litter. Based on this research a biogas plant (digester) with a volume of 2 m3 was designed, constructed, and operated, as a result of digestion in 20 days, biogas with the content of methane (CH4 ) 65.77% was obtained. The study also calculated biogas production in a thermophilic and mesophilic mode for 20 days in June and July to assess the energy supply of the “Kekech” poultry farm with 45,000 chickens. The results of the research showed that in thermophile mode in May month on average per day, it is possible to receive 167200 m 3 of biogas, and in mesophile mode 162954 m 3 , and for July month for thermophile mode 158554 m 3 /day, and in mesophile mode 165000 m 3 /day.
