Potential of Biogas and Electricity Production from Animal Waste in Turkey

In this paper, biogas potential produced from animal manure has been calculated using data for various regions of Turkey between 2007 and 2019. Moreover, generation of electricity potential that can be provided using biogas obtained from animal manure resources has been examined. The animal numbers subjected to the study have been reached via the Turkish Statistical Institute. The amount of animal manure, which is the basis for calculating the amount of biogas, has been calculated using the average number of animals and the animal weight. Eastern Anatolia and Central Anatolia Regions have the highest biogas potential with 19% compared with the other regions due to amount of manure obtained from animal. The finding of this study denotes that 76,448 × 106 m3 potential of methane content can be obtained from biogas for the mentioned years, and 2,339,296 × 106 MJ potential of heating value can be obtained from this methane value. While the potential of electricity energy, which can be provided from animal manure wastes, has been 231,009 × 106 between 2007 and 2019 in Turkey, the total electricity consumption in 2007–2019 is 2,898,040 × 106 kWh. The results show that the potential electricity that can be provided from animal manure could meet 7.99% of the electricity consumed in the same years. Furthermore, the cost analysis of biogas facility, which is established in Eastern Anatolia Region, has been performed using circular economy model. According to calculations, the discounted payback period has been found to be 10 years.
