Production and Quality Evaluation of Biogas from Animal Waste (Cow Dung)

Abstract

The production of biogas from animal waste offers a sustainable and eco-friendly solution to global energy demands while addressing Agricultural waste management challenges, and turning waste to wealth. This research is aimed at producing and evaluating biogas from cow dung. The biogas produced was gotten from the anaerobic digestion of cow dung, in the absence of oxygen, using a locally made digester. The biogas generated from the anaerobic digestion process was analyzed in the laboratory using a portable gas meter, and the data generated through triple determination, were subjected to statistical analysis using a Statistical Software Packages for Social Sciences (SPSS version 23) to obtain the mean values and standard deviation. Results of the compositional analysis obtained were as follows: 65.86% methane (CH₄); 27.15% carbon dioxide (CO₂); 2.74% carbon monoxide (CO); 2.16% hydrogen sulfide (H₂S); and 2.09% oxygen (O₂). The result gotten from the analysis demonstrates the viability of cow dung as a feedstock for renewable energy production with methane content indicating a significant calorific value.
