INVESTIGATION OF BIOGAS GENERATION CAPACITY FROM ANIMAL MANURE IN BITLIS PROVINCE

Abstract

Today, most of the energy needs are met from exhaustible fossil fuels, which leads to environmental problems. Therefore, the development and use of renewable energy sources is becoming increasingly important. This study examined the biogas potential derived from local animal manure waste in the city center and areas of Bitlis. Additionally, the equivalent heat and electricity energy potential of the determined biogas amount was calculated. According to the data obtained in the study, the biogas production capacity varied between 27.235 million m³, 27.486 million m³, 24.838 million m³, 20.760 million m³, and 20.594 million m³ from 2019 to 2023, respectively. The equivalent thermal energy amounts that can be obtained based on the biogas production capacity were calculated as 136.18x109 kcal/year, 137.43x109 kcal/year, 124.19x109 kcal/year, 103.80x109 kcal/year, and 102.97x109 kcal/year, respectively. The equivalent amounts of electricity energy in the same years were calculated as 128.00 GWh/year, 129.19 GWh/year, 116.74 GWh/year, 97.57 GWh/year, and 96.79 GWh/year, respectively. Biogas production from animal manure not only reduces the environmental impact of waste but also increases agricultural productivity by providing valuable byproducts such as fermented fertilizer. This process offers both economic and ecological benefits, contributing to sustainable energy production.
