Feasibility of Low-Capacity Waste-to-Energy Plants in the Czech Republic
Putna, Ondřej ; Frýba, Lukáš (referee) ; Pavlas, Martin (advisor)
The diploma thesis is focused on the evaluation of small-scale waste to energy plants in the Czech Republic. In the first part, there is a survey of the corresponding literature and general evaluation of the specificities of these plants. The next section analyzes the technical and economic indicators of a specific technology by Microsoft Excel model. Finally, recommendations for small-scale waste to energy plants arising from the model are summarized.

The influence of disintegration of the input material for the production of methane by anaerobic fermentation
Herman, Pavel ; Frýba, Lukáš (referee) ; Houdková, Lucie (advisor)
This master‘s thesis deals with the influence of disintegration of brewer's grains for the production of biogas by anaerobic fermentation. The first part introduces us with the issue of biodegradable wastes. There are given their characteristics, ways of handling with them and legislative restrictions associated with them. In other sections there is a detailed description of anaerobic fermentation itself, including characteristics of biogas. Then there is issue of disintegration during fermentation including a list and characteristic of some disintegration methods. The main part of the thesis consists of description of the experiments on which it is observed increment of biogas based on the disintegration of brewer's grains and the evaluation of the individual experiments including the calculation of economic of the disintegration in laboratory conditions.

Evaluation of the alternatives of PCDD/F removing in the incineration plants
Frýba, Lukáš ; Kropáč, Jiří (referee) ; Bébar, Ladislav (advisor)
The thesis is focused on analyzing the current status of the technology used for cleaning flue gas from persistent organic pollutants, especially PCDD/F. For the three most commonly used methods of solution operational and energy efficiency comparison was made, where achievable energy export and the impact of the change in working conditions on the efficiency indicators of energy production and use of the energy was evaluated. In conditions we considered an alternative machine-technological solutions used for the final disposal of persistent organic pollutants resulting from the waste combustion in terms of additional operating costs and energy efficiency.

Up-to-date technology for energy utilisation of biomass and waste
Krňávek, Martin ; Frýba, Lukáš (referee) ; Kropáč, Jiří (advisor)
The bachelor‘s thesis deals with technologies for energy utilisation of biomass and waste. The introductory part is dedicated to biomass, its division and sources of biomass suitable for thermal treatment. The main part describes and compares technological units for energy utilisation of biomass, which is important for the Czech market. Furthermore there is described selected technologies for flue gas cleaning suitable especially for thermal treatment of waste. A basic design calculation of technological unit fired with wood chips for combined heat and power production is included here.

Waste incineration in states adjacent to Czech republic and the potential of international waste market
Kadleček, Vít ; Frýba, Lukáš (referee) ; Ferdan, Tomáš (advisor)
This bachelor thesis deals with mapping of current and planned waste incineration plants in states bordering with the Czech Republic, and with the potential of international waste market. The introduction of the thesis describes the history and function of the waste incineration plants. The first main part, the legislation, defines waste incineration as energetic usage of waste, placing waste incineration to waste management and legislative conditions for realization of transportation across borders. The second main part informs about current and planned foreign waste incineration plants, which are located near to borders of the Czech Republic, because of formation of competition for planned projects in the Czech Republic.

Energetical utilization of waste, especially sewage sludge
Havlásek, Martin ; Kuba, Pavel (referee) ; Frýba, Lukáš (advisor)
This bachelor´s work discusses about energetical utilization of sewage sludge. The process is described from sludge treatment to flue gas cleaning. The main emphasis is on incineration, which are governed by legislation. First are listed sludge treatment and utilization technology which included thermal processing in which is thoroughly described the process of incineration. The following are methods for co-incineration of sludge and devices for direct incineration. Work is finished by chapter about flue gas cleaning.

Household waste transport
Gal, Pavel ; Frýba, Lukáš (referee) ; Pavlas, Martin (advisor)
Bachelor's thesis deals with issue of collection of mixed municipal waste to waste-to-energy. The main part is aimed to transportation of waste using rail freight or road freight transport. It shows the advantages of rail transport and compares transport in term of emissions and economy. The final chapter deals with preparation data for optimization problem and visualization of them using software ArcGIS.
