Utilization of biodegradable waste
Švec, Jan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this paper is to summarize the current situation of the problem using biodegradable waste. The introductory chapters deal with descriptions of different types of biodegradable waste. The main part describes ways of handling this waste. For various types of waste are listed by their most appropriate treatment and further use. Emphasis is placed on legislation dealing with that waste legislation on the processing equipment.

Household fermentor design
Švec, Jan ; Jecha, David (referee) ; Houdková, Lucie (advisor)
The aim of this thesis is to design a fermentation unit specially adjusted for household operating. Unit processes kitchen and garden biodegradable waste with requirements of low acquisition costs, operating costs and demands of service. Benefits of this unit are production of biogas, which will be utilized in household, and processed of biodegradable waste to nutritious manure. The first part of the work is aimed on description of anaerobic fermentation process and summary of operating conditions. The main part deals with potential of household and garden biodegradable waste for production of biogas and design of fermentation unit. Proposals for biogas utilization and economy of whole project are mentioned.

Production of electric energy from biomass
Buřil, Tomáš ; Škvařil, Jan (referee) ; Moskalík, Jiří (advisor)
The objective of this bachelor´s thesis is to summarize possibilities of energy use of biomass, especially a production of electric energy. The thesis describes and shows theoretical principles of used processes, as well as technical devices for getting energy. Among used processes belong combustion of biomass, thermic gasification and anaerobic fermentation connected with production of biogas. Electric energy is in these cases produced in combination with thermic energy, a process like this is called cogeneration. In the second part, technical solution of a biogas station in Vidochov is described. There are also stated reasons for its building, as well as an economic return of the investment.

New technologies for an efficient operation of biogas plants
Uhlířová, Marcela ; Máša, Vítězslav (referee) ; Vondra, Marek (advisor)
This bachelor thesis is focused on new technologies enhancing efficient operation of biogas plants. The introductory part describes operation of biogas plant, its products and issues. The main part of the thesis deals with description of three progressive technologies concerning biogas plants such as dry fermentation, hydrothermal pretreatment and biogas upgrading to biomethane. For each technology there is a description, advantages and disadvantages with regard to their practical applicability.

Bio-gas power plant
Mészáros, Gabriel ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
The master’s thesis is focused on the possibility of using biodegradable materials (animal manure, energy crops, crop waste) in a biogas plant. The first part deals with the mechanism of production of biogas. Described are factors which affect the production of biogas, its composition, properties, utilization and potential substrates. The next chapter deals with the technologies of biogas plants. The main part of the thesis is devoted to a proposal of a specific biogas plant in the Slovak Republic in the Novozámocký district. Included is the processing of design proposal, selection of components and proposal of the layout of biogas plant. The economic evaluation includes quantifying capital and operating costs and profits from the sale of electricity and compost.

Combined heat and biogas production using a bioreactor
Novák, David ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
This diploma thesis deals with the bioreactor system and its use for the production of heat and biogas. The bioreactor uses the composting and metanogation process of fermentation that humanity has known for hundreds of years, but the combination of these processes is a relatively unexplored area. The theoretical part of the thesis analyzes the existing possibilities of utilization of the heat generated in the compost, and also describes the used technology of small biogas stations and other small systems for biogas production. It follows the practical part of the work, when it was the task to design a bioreactor working at low temperatures during the winter. Part of the solution is the initial design and testing of the basic test structure of the bioreactor, followed by the implementation of a more advanced and more complex system, including a control and measuring center realized by a microcontroller.

Renewable energy sources in the region of the North Moravia
Mazák, Tomáš ; Hrnčířová, Michaela (referee) ; Pospíšil, Jiří (advisor)
The content of this work is to search an overview of basic types of renewable resources in the region of the north Moravia, respectively in the Olomouc region. In this work, are clearly described the main sources that are used in our country, especially the potential of photovoltaic systems, wind energy, water energy and biomass. For each type of renewable source is depicted a principle and the possibility to use just in the region of the north Moravia. In addition, specific applications are described in the Olomouc region, using these energy potentials.
