My work assesses the technology use of corn silage extrusion for biogass production based on biological proces, technological limits, legislation and financial indicators of the biogass station. The theoretical part of the thesis is focused on the extrusion process. Based on the robust simulation of the experimental part we can conclude, that the pressure of 1.372 MPa probably moves close to the biotechnological optimum in the relation to the kinetics production of CH4 in certain conditions (the temperature of 38 °C, the delay time of the corn silage in the high pressure extruder CZ UV 21314 was 600 s). From the economic point of view, the assessment was carried out using the net present value (NPV), which serves as a criterion for evaluation of the profitability of investment projects. The technology seems to be a very interesting alternative not only for financial viability reasons, but also in relation to the environment.
