Abstract:
The increasing global demand for sustainable and renewable energy sources has intensified research into biogas production from animal wastes. This study evaluates the biogas production potential and energy conversion efficiency of different animal dungs, including cow dung, poultry manure, pig dung, and sheep/goat dung, through anaerobic digestion. The substrates were digested under mesophilic conditions for a defined retention period, and the volume of biogas produced was measured daily. Results revealed that cow dung yielded the highest biogas volume of 0.070 m³/kg, followed by poultry manure (0.055 m³/kg), pig dung (0.045 m³/kg), and sheep/goat dung (0.040 m³/kg). Energy conversion efficiency was assessed based on the methane content and calorific value of the biogas obtained. Cow dung exhibited the greatest energy potential, indicating its suitability as an efficient feedstock for bioenergy generation. The findings highlight the significant role of animal waste in renewable energy development and environmental sustainability, offering an eco-friendly solution for waste management and rural electrification.
