Determination of Biogas Potential from Animal Waste in Tokat Province

Abstract

With the increase in the world population and the continuous development of technology, energy demands continue to increase. In general, the global energy needs are met by fossil sourced fuels. Depleting nature of fossil energy sources, their negative impacts on environment, increasing energy demands have led the efficient use of energy sources and the shift to local and renewable energy resources. Biogas is a renewable energy resource. Since organic wastes are used in biogas production, biogas offers a significant way of elimination of wastes and a source of energy. Animal wastes are the primary source of biogas. In this study, it is aimed to determine the biogas potential of Tokat province from animal wastes. Depending on this purpose, the amount of waste and biogas that can be obtained from animal waste and the energy potential that can be produced have been revealed by using the current data of the Provincial Directorate of Agriculture and Forestry. Energy equivalents of the biogas that can be obtained were also calculated. According to 2021 data, there are 303.952 cattle, 511.457 sheep and 247.333 poultry in Tokat province. Annually, 245.988 tons solid animal waste are obtained in Tokat province. In this study, conducted with the 2021 data of Tokat province, the amount of biogas that can be produced from animal wastes was calculated as 49 million m3/year. Districts with the greatest biogas potential are Merkez, Turhal and Zile respectively in 2021. The energy equivalent of biogas produced has been calculated as 292.000 MWh/year
