Abstract
Energy is essential for the progress and development of nations. It must be reliable, affordable, and environmentally friendly. Among the most promising renewable energy sources, biogas technology has been developed to secure the existing energy supply. However, there is a need for more scientific research on the optimal use and performance of biogas plants for beneficiaries and installers. This study investigated the chemical composition of cow dung and its specific heat capacity. The results show that elements such as Al2O3, CaO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SiO2, and TiO2 have different chemical compositions. Furthermore, the results show that cow dung’s composition and oxide content affect its specific heat capacity. Dzwerani had the highest concentrations of Al2O3, Fe2O3, and SiO2. Since the oxide composition of the dung samples from Tshino, Maila, and Gogogo differed, their specific heat capacities were also different. The results of this study encourage further investigations to determine a more accurate relationship between specific heat capacity and oxide composition.
