Determination of the biogas potential of animal waste and plant location optimisation: A case study

Biomass energy sources consist of materials such as wood obtained from forests, wastes from agriculture and forestry processes, and industrial, human, and animal wastes. Biogas energy is generated as a result of the anaerobic decomposition of biomass. The analysis of biogas energy potential from animal waste plays a significant role in developing countries, which involves Turkey. Therefore, the work executed in this article presents a case study for such regions. A comprehensive analysis for the production potential of biogas from the wastes of breed animals in TR83 region in Turkey, which includes the provinces of Amasya, corum, Samsun and Tokat is presented in this study. The number of animals and their total waste generation were determined. Then the biogas potential, along with the electricity production and the reduction of CO2 emissions, were calculated accordingly. In addition, the amount of biogas that can be produced in the TR83 region has been determined to be 151.8 M m(3) per year from cattle, 6.3 M m(3) per year from small cattle, and 12.9 M m(3) per year from poultry. As a result, the optimal location for biogas plants based on supply chains were determined. Accordingly, the electricity potential that can be generated for the TR83 region has been determined as 49.25 MW. In addition, it has been found that approximately 19 times more carbon emissions will occur if electricity is obtained from natural gas, and approximately 34 times more emissions will be given off if it is obtained from imported coal. Ultimately, the resulting facility placement points were found to be Suluova, corum, Sungurlu, Bafra, carsamba, Vezirkopru, Erbaa, Tokat and Zile.
