ABSTRACT
Investigation of Biogas Production Potential from Chicken Manure
The traditional energy resources are consuming. So the danger of consuming of the
resources by years directs human being to find new and renewable energy resources.
Today, the using of a new and renewable energy sources such as solar, wind and
biomass are increasing day by day. Biogas production from chicken manure with
anaerobic digestion is an important alternative energy source. By this way, waste is
converted to biogas which has hygienic, useable and high energy content. The
advantages of anaerobic processes include high degree of waste stabilization, reduction
in pathogens, no oxygen requirements, production of biogas, and agricultural application
of decomposed product.
In the study, the potential of biogas production from chicken manure was investigated
by using a laboratory scale anaerobic digestion reactors. These reactors were placed into
water batch operated at 35 ±1 °C with electric heater. Studies were carried out in two
stages. At first stage, solid ratios were regulated to 2,5%, 5%, 10% and 15% while rate
of inoculation was 10 % (volumetric). At second stage, inoculation ratios were regulated
to 0% and 2.5% while rate of solid was 10 % (volumetric). Biogas composition was
determined by using orsat apparatus. Biogas quantity was recorded by manual from
scaled gas collection tank. During 90 days, the end of experiments, biogas production
per solid decreased with increasing of solid ratios, and increased a bit with increasing of
the inoculation ratios.
Key Words: Biogas, anaerobic digestion, chicken manure.
