The Specifics of the Construction and Operation of Agricultural Biogas Stations
Chládek, Ivo ; Kolář, Pavel (advisor) ; Hašková, Simona (referee)
The subject of this thesis is precisely what one sentence he says her name - the specifics of the construction and operation of agricultural biogas plants ( BPZS ) including assessment of their economic efficiency in terms of the existing subsidy , subsidy and incentive policies for renewable energy sources ( RES) . The site -specific construction and operation in the detail reports for this purpose specially modified documents business plan - feasibility and economic audit. Economic efficiency of the existing subsidy , subsidy and incentive policy examines modern fundamental financial analysis projects based APV ( taking into account the effects of special financing details of the NPV) . Based on its findings the conclusion of the practical part of the thesis formulated specific recommendations that can effectively contribute to the suppression of the feared consequences of the expected boom BPZS development in the country.

Effects of different intensities of fertilization to yield of selected species of energy grasses
GAZÁREK, Lukáš
The importance of renewable energy sources increases with increasing power consumption and heat generation while declining reserves of fossil fuels. For the Czech Republic in future could be a very important source of biomass electricity. Bachelor thesis in the first part literature review describes the importance of renewable energy sources and their different types and use in our country. In other parts of this work closer look at the use of biomass to produce electricity and heat. Eventually, the paper describes two selected species of grasses and energy to: Reed canary grass (Phalaris arundinacea L.) and Szarvasi - 1. In the end review of the literature deals with the individual plant nutrition macro- and microelements, and finally describes the fertilizer that was used in the cultivation plants specified above. In the practical part conducted experiments in three intensities fertilization. The first variant was called. Extensive when plants were fertilized. In the second variant was used ammonium sulfate, ammonium nitrate, superphosphate and triple potassium salt. The latter variant was fertilized digestate as a product of a biogas plant in which these plants are growing just as the input product. The measurement revealed some interesting facts. According dry matter yield responded Phalaris L. arundiacea best to fertilization with mineral fertilizers, poorer yields gave variant fertilized by digestate and lowest yields were recorded for extensive, or unfertilised stand. Elymus elongatus provided in its spring mowing best result in fertilized by digestate form and fall in intensive variant. Both plants provide higher returns in the spring mowing, mowing than in autumn. In the yield of fresh matter during the spring harvest proved the use of organic digestate, while the harvest of autumn fell the most intense flavor. According to the percentage of dry matter content is the best option appeared to be extensive with the exception of the autumn harvest Phalaris arundiacea when intense flavor gave the highest dry matter content.

Proposal for measures to increase the efficiency of biogas station Obora
NOVÁKOVÁ, Renata
In my thesis, entitled "Proposal for measures to increase the efficiency of biogas station Obora" in the theoretical part deals with factors affecting the efficiency of biogas plants. The practical part focused on the specific biogas plant solves the technological and economic aspects of the station. It also deals with waste heat produced during electricity generation, feedstocks, the use of digestate and biogas station linked with the adjacent farm. The thesis also discusses the problems with which the biogas plant in Obora meets, which have significant impact on the efficiency of the biogas plant.

select suggestions for increasing the efficiency of biogas plant in Koloměřice.
ČERVENKA, Pavel
In my bachelor thesis I will try to introduce the topic of importance and operation of biogas plants. The theoretical part focuses on the entire operation of biogas plants, types of biogas plants, the inputs and outputs and processes. The goal of the practical part was to describe the biogas plant in Koloměřice, make out the processing of by-products and select suggestions for increasing the efficiency of biogas plant in Koloměřice.

Biogas Plant and its impact on the environment.
MACH, Marek
In my work I try to bring the topic of meaning and operation of biogas plants and their possible noisy burden on the surrounding environment, especially in populated parts of the municipalities in which the biogas plants are located. The theoretical part is focused on all traffic biogas, from their division, despite possible inputs and outputs, and the processes that happen inside the station. The theoretical part also contains noise that can be issued for machinery undisturbed environment. The practical part of this work was to measure the noise emitted by the station at full capacity, and if possible under all operating conditions, such as management of raw materials and export of digestate. From the measured values, we will try to determine if stations do not affect the life of the surrounding communities and their residents.

Growing corn for biogas production
POSLUŠNÝ, Marek
In my bachelor's thesis I deal with a corn growing and it's irreplaceable role in a biogas production in BPS according to a suitable hybrid for given manufacturing conditions. The alternative use of corn as an energy plant shows one of the ways which are followed by some agricultural companies. With regard to use of current technologies for a corn silage production, and a possibility to use a biogas waste product as an adequate fertilizer and mainly the biogas production helps to stabilize the companies financially.

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.

Evaluation of economic efficiency of investments - biogas plant
Zemanová, Pavlína ; Srpová, Jitka (advisor) ; Habrmanová, Blanka (referee)
The subject of this thesis is to evaluate investments in biogas plant purchased by company AGRA Deštná, a.s., which is located in Deštná, near Jindřichův Hradec. The thesis is divided into two main parts. The theoretical part is devoted to theoretical assumptions of investment evaluation, grants, theories and legislation related to the biogas plant. The practical part of the thesis describes the current situation of the company, investment, and economic evaluation of investment in the construction of biogas plants.

Not In My Back Yard effect - attitude of local people to a planned construction of biogas plant
Novotná, Miroslava ; Melichar, Jan (advisor) ; Kaprová, Kateřina (referee)
The aim of the thesis is a research of the "Not In My Back Yard" effect, a negative attitude of local people to a construction of a new and potentially dangerous project in their vicinity. The thesis quantifies strength of the NIMBY effect in Městec Králové, a town where a biogas plant is planned to be constructed. The hypothesis is that the strength of the NIMBY effect is higher for the people who live in a higher proximity to a planned construction than for the people who do not.The hypothesis is evaluated based on data gained by an own survey conducted among residents of the town.Quantification of the NIMBY effect is more frequently a subject of research of foreign studies; empirical studies of biogas plants are rather rare. From this reason I have implemented a study of population of Městec Králové and tried to prove whether presence of the "Not In My Back Yard" effect can be indicated.
