Sažetak
Anaerobic digestion is the biological degradation of organic material in the absence of air and may imply environmental benefits with regard to waste treatment, pollution reduction, energy production, and improvements in agricultural practices. An anaerobic digester is a system that harnesses this natural process to treat waste, produce biogas that can be converted to heat and electricity and anaerobic digestate, a soil improving material. The paper presents the building of a mini digester for mesophilic anaerobic digestion. With the mini digester the amount of biogas production (methane) from different organic wastes is observed. The basic structure is made of stainless steel, on which other components are fixed. The most important components are the eudiometers, pump and heater with thermostat, fermenters, thermometer and barometer. The experiment is made according to DIN 38 414, part 8. After building of a mini digester some experiments with different organic materials are made.
