The current thesis focuses on the chemical analysis and comparison of appropriately selected agricultural and municipal waste (liquid pig manure and solid coffee grounds) used in anaerobic continuous stirring reactor (CSTR), attempting to produce biogas. During the experiment, the hazard of the heavy metals of the nutrition was investigated by the X-Ray Fluorescence Spectroscopy (XRF). Moreover, the quality and quantity of produced biogas were analyzed by other methods and technics and the results of the experiment were compared by combining a mixture of liquid pig manure and solid coffee grounds with results of only liquid pig manure.The first and theoretical part presents the process of anaerobic digestion and the feedstock introduced into the anaerobic reactor to complete the experiment with successful degradation of organic residues. Additionally, the first part presents the XRF and other methods and techniques which are used for biogas production. The second and experimental of the thesis describes the various experimental biogas production and XRF measurements. Finally, the third part depicts the conclusions and suggestions for finding even more efficient materials that can be used in the future.
