The design of the production of biogas from fresh grass.
ŽIVNÝ, Jakub
Work is concered with the biogas production from the fresh grass mass, which come up when the grass is being cut on regular basis in the parks and side parts of communities and cities. There is a detailed description of the biogas production defined in the beginning of the Theses in the literature overview. Next, we define the material properties suitable for the biogas production, concerning on the grass mass. In practice, there is a prototype example showing how the biogas station could manipulate the fresh grass mess in real, linked to the harvest line.

Using of digestate of agricultural biogas stations
VERNER, Dušan
This work deals with problems of agricultural biogas stations with the focus on using of final product of anaerobic fermentation, digestate, on agricultural soil. It evaluates its fertilizing effect in comparison to industrial fertilizers. The results showed that the fertilizing effect can improve economy of growing plants, however it depends on quality of digestate, constitution of base input material and technology of processing. It is not possible to use digestate anytime, it depends on growing crops and its technology. Nevertheless digestate as a final product of anaerobic fermentation is an interesting fertilizer.

Utilization of Zea mays L. for energetic effects
RATAJ, David
This bachelor thesis deals with the types of energy use of flint corn (Zea mays). It compares the suitability of hybrid maize lines. The thesis is to summarize and compare the literature data on other types of energy crops and compares them suitable for cultivation for energy recovery on the basis of some production capacity and energy parameters (dry matter yield, energy recovery, combustion heat and humidity).
