Purpose: The aim of the paper is to present the construction of a mini digester for biogas production from different agriculture plant biomass and other organic wastes. The amount of biogas production (methane) is observed by the mini digester. Design/methodology/approach: The mini digester consisting of twelve units was built and some measurements with agriculture plant biomass were performed according to DIN 38414 part 8. Four tests simultaneously with three repetitions can be performed. Findings: With the mini digester the amount of biogas production is observed. The parameters such as biogas production and biogas composition from maize and sugar beet silage in certain ratio were measured and calculated. The highest biogas and methane yield was 493 NI kg VS-1 or 289 NI CH4 kg VS-1. Research limitations/implications: The scope of substrates for the anaerobic digestion process is on the increase so the interest in the use of the biogas as a source of a renewable energy is very high. With mini digester it is possible to observe the amount of biogas (methane) production and so the most suitable plant giving the maximum methane yield, can be determined. Practical implications: The aim of biogas as renewable source of energy is to replace fossil fuels with sustainable energy production systems and to fulfil the requirements of the Kyoto Protocol. On big farms the liquid manure and different energy crops can be used for biogas production. That can improve the economical efficiency of the farm and reduce the CO2 emissions. Originality/value: Mini digester for biogas production was built as special equipment. The quality of produced biogas is determined with a gas analyser GA 45.
