Catching the Biogas Opportunity: Determining the Animal Waste-Based Biogas Potential and Environmental Effects for Sirnak

Anaerobic digestion of renewable feedstocks into biogas is an important technological approach for sustainable and reliable energy supply. Biogas is produced from biomass and is defined as a gaseous energy carrier containing 60% methane and 35-40% carbon dioxide. Although different types of biomass samples can be used for biogas production, the use of animal wastes in biogas production is more preferred than others. The region selected in the study is a city with a significant amount of animal waste production and thus biogas potential due to intensive animal husbandry. In this study, the animal waste potentials that can be produced from cattle, sheep, and poultry in Sirnak province and their effects in terms of biogas equivalents and carbon emissions were analyzed. The results of the study show that a total of 23.445 million m3 year-1 biogas can be produced from animal wastes in Sirnak province from all districts, while total electricity production is 44,238,955.45 kWh year-1. As an environmental impact, it has been determined that total CO2 emission can be 276,356,209.6 kg CO2/year, on the other hand, a reduction in total CO2 emission up to 209,809,869.8 kg CO2/year can be achieved.
