Abstract

The purpose of this study was to determine the biogas production capacity from animal

wastes in Marmara region of Turkey for the years 2005–2014. The wastes from the cattle and hen

in the region were considered the resource for biogas production taking the number of animals

and the collectability of the wastes into the account. Three scenarios were evaluated to estimate

the biogas capacity by assuming that 100% (theoretical potential), 50%, and 25% of the total

animal waste could be used for biogas production in the region. For theoretical biogas production

from cattle wastes, the greatest potential in the year 2014 was calculated for Balıkesir province

with 145.53 Mm3, followed by Çanakkale, Bursa, Sakarya, and other seven provinces. Balıkesir

had the highest biogas potential in 2014 from the poultry waste, too, followed by Sakarya,

Kocaeli, Bursa, and other seven provinces. Biogas potential (100%) of Marmara region increased

by 15% from 2005 to 2014 with 1,242.17 Mm3 in 2014. The heat and electrical energy equivalents

of the biogas were found to be 7,453.02 GWh and 2,608.56 GWhe, respectively. In the other two

scenarios, depending on the utilization rate of theoretical biogas potential: biogas amount, heat

and electric power values were determined proportionally.
