Production of biogas as an automotive fuel from renewable materials
Frühbauer, Zdeněk ; Houdková, Lucie (referee) ; Dlabaja, Tomáš (advisor)
The aim of this thesis is to specify and summarize possibilities of biogas production as a motor vehicle fuel by using the renewable energy sources. In the first part of the thesis there are the data concerning biogas, its production and chemical composition. An important part of the thesis is a description of current most used methods of cleaning which adjust biogas to quality of natural gas. The important part of this thesis is to introduce some of already working projects and to get knowledge about possibilities of making biogas from biologically decomposable material as a renewable energy source. The close of the thesis deals with energy, economy and ecological audit too and values biogas through all angles which decide about its using in larger size in the car industry.

Biogas technologies
Martanová, Iveta ; Jecha, David (referee) ; Beňo, Zdeněk (advisor)
This bachelor's work deals with technology of conception and production of biogas from biodegradable waste. In the introductory part there is elaboration of biogas facts, the principle of biogas origin and the usage of biogas in practice. The main part is dedicated to individual technology of the biogas production. There are descriptions of technological equipment for gas producing and descriptions of individual methods of waste processing indicating their advantages and disadvantages.

Fractionation of biodegradable municipal waste to produce biogas and solid biofuels production
VELEK, Jindřich
The theses deals with the use of biologically degradable waste which needs to be processed and utilized in maximum amount. It is highly desirable to apply new and well-known technologies to treat such waste efficiently and not to dispose it in landfills unreasonably, as is the case at present. The paper describes landfilling, composting, anearobic digestion, mechanical and biological treatment of waste as well as various stages of the lability concerning fractions of organic compounds. The stages of the lability concerning fractions of organic compounds are in particular determining the best utilization of such biologically degradable waste in each technology. It is advisable in this case to apply the STEAM EXPOLOSTION or IFBB technology for treatment of biologically degradable waste. These technologies were used in the proposal for the utility model which specifies how to produce biogas or solid biofuel from waste.

Mechanization intensive composting technology
HLAVINKA, Pavel
This bachelor thesis is focused on the intensive compost technology and the biogas production of the biologically decomposable waste. The theoretical part describes the technology of compost production in the tracked piles as well as in the loose areas, followed by the description of the biogas technology and biogas stations with all the related equipment. The biogas is the main product of the anaerobic digestion. Subsequently, we describe the conditions necessary for the biogas production, e.g. the constant temperature, pH, and the nutrients? presence. In the field part of the thesis there we describe the AGRO?Otročín plc. biogas station, as well as the technology hereby in use and its individual parts with the concrete values and figures followed by the basic characteristics of the cogeneration aggregate and the noise level measurements of the technology presented.

Current technologies and landfilling of waste and its prospects in the Czech Republic
VELEK, Jindřich
This bachelor thesis deals with waste management in the Czech Republic, especially landfilling. Different types of landfills, their technical aspects and methods of depositing waste are described. The thesis also describes the main legislation concerning waste management in the Czech Republic and tries to point out material and energetic use of waste before landfilling. Recycling is considered to be important because it decreases the amount of waste stored in landfills. Composting and anaerobic digestion are the other methods of disposal. The thesis also describes the possibilities of usage of the landfill gasses with the help of cogeneration units. The thesis refers to current level of waste landfilling in the Czech Republic and predicts the future development.

Energy utilization of the biodegradable component of municipal waste in the city of České Budějovice
SÝKOROVÁ, Žaneta
My thesis is aimed at the possiblities of collecting and utilizing the biodegradable component of municipal waste in the specific environment of České Budějovice. The thesis includes a proposal to construct a municipal biogas plant to decrease the volume of mixed municipal waste. The goal of this part of the thesis is to compare expected costs and income of the project and determine the general economic indicators and evaluate the investment, so that the project can be either fully recommended or rejected.

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.

CONTEMPORARY PRACTICE IN DISPOSE OF BIODEGRADABLE WASTE
Šmejkalová, Zuzana ; Geuss, Erik (advisor) ; Havránková, Věra (referee)
This diploma paper deals with contemporary practice in dispose of biodegradable waste, especially biodegradable communal waste (biowaste) in the Czech Republic. It explains fundamental terms, points out relevant legal rules and describes methods of biowaste handling. It evaluates collection and utilization systems in two cities in the way of comparison method. It compares them from cost and benefits (economic, environmental) points of view. The main purpose of the diploma paper is general introduction into the issue, pointing out negative effect of biowaste landfilling and presentation of actual systems of utilization. Also the work points out contemporary trend consisting in raising separation and reducing biodegradable communal waste landfilling.
