Analysis of Municipal Solid Waste Composition
Novák, Michal ; Kropáč, Jiří (referee) ; Šomplák, Radovan (advisor)
This diploma thesis provides extensive research of municipal solid waste studies and methodologies from all over the world. Firstly, the studies are described in general and then divided into several groups depending on the principle of their working practices, including their advantages and disadvantages. Secondly, the studies are divided by geographic areas. The results of the individual studies are presented and compared. Based on the findings in the thesis, appropriate methodology for municipal solid waste analysis in the Czech Republic is proposed.

Waste-based renewable energy production
Strapko, Tibor ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Following diploma thesis deals with waste-based renewable energy production. Waste is a very heterogeneous mixture consisting of various materials with different origin. This can be either fossil or biogenic. The very substances with biogenic origin are considered renewable energy source with financial support from state. Therefore is nowadays tendency to develop a method, which can determine the biogenic waste ratio. The method, aside possible cheapest price and simplicity, should be also reliable and easy reproducible due to its usage. At the beginning, thesis focuses on the waste-to-energy facilities. Important part deals with legislative side of this topic. The reasons, why Czech Republic is behind with thermal waste treating are stated as well as Czech Republic’s obligations to European Union in the field of biodegradable municipal solid waste. Main part of thesis deals with different methods to determine biogenic waste ratio in municipal solid waste. Step by step are introduces 4 known methods, where especially sorting, balance and 14C methods are described closely. By each method are stated its major benefits and handicaps in case of using. Finally, the computational model, which is based upon balance methods equations, is introduced following with feasibility study of balance method for local conditions. The very end of the thesis brings comparison of each method results, general summary, where are results of this thesis stated and possible trends for future in this area of expertise, as well.

Energy use of waste
Lachman, Jakub ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The bachelor’s thesis deals with the Waste-to-Energy topic. The first part evaluates municipal solid waste (MSW) as fuel, analyzes the influence of its indiviual fractions on the overal properties, mainly the lower heating value, compares MSW with other conventional solid fuels which are thermally used. The second part of the thesis deals with Waste-to-Energy technologies. It is divided into three parts: combustion, pyrolysis and gasification. Each contains both the description of the process itself as well as the description of the applied technology. The last chapter contains some of the negative impacts of Waste-to-Energy technologies and a list of measures used to deal with them.

Application of stochastic programming methods for the purpose of energy producing system
Šomplák, Radovan ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
This thesis deals with the evaluation of the strategic investment in the waste-to-energy plant development. The central supply of heat and the incineration plant connection can be provided for example by the distribution network. The objective is to find financially feasible solution regarding uncertain development of waste management and energy market. A heat supplies to district heating network significantly influences the strategic decision. A two-stage stochastic programming based on the scenarios and the GAMS software were applied to solve this task. The main contribution of this thesis is decision on crucial parameters of the waste-to-energy plant.

Energy use of waste
Hrubý, Radomír ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The content of this work is an evaluation of the Waste-to-Energy technology. The in-troduction describes current position of the Czech Republic on waste management. Including description of individual waste management technologies. The following chapter deals with the use of waste as a fuel for energy purposes. The principle of waste incineration and pyrolysis technology is elaborated here. Further, are discussed the methods of purification of individual components of flue gas. The penultimate chapter is devoted to legislation that affects the ecology of Waste-to-Energy technology and the comparison of emissions of various stationary sources of pollution which are producing energy. In conclusion, there are described facilities for the energy utilization of municipal waste in the Czech Republic, which are supplemented by two facilities from neighboring states.

Web application for planning waste fractions collection
Kubowský, Jiří ; Šeda, Miloš (referee) ; Dobrovský, Ladislav (advisor)
The aim of this thesis is to develop a web application to support the planning of waste collection with an emphasis on a user-friendly interface and variability in terms of configurability of task boundary conditions. The development of the application builds on models and algorithms developed in the field of waste management. The application will be a tool for end users to work with these data, models, and algorithms. In the theoretical part, the issues of waste sorting and collection are presented. The practical part deals with the development of the web application from the basic concept, through the technologies used, to the details of the actual implementation.

Regression Analysis of Spatially and Time Distributed Data
Rosecký, Martin ; Hübnerová, Zuzana (referee) ; Bednář, Josef (advisor)
This thesis summarizes findings about municipal solid waste (MSW) forecasting. Basic information about linear regression and correlation analysis were described. Analysis of influencing factors was realized on municipality with extended competence level. The resulting models explain up to 99 % of variability. Final models of MSW per capita explain between 12 and 75 % of variability. Variability explained by model of MSW per capita is lower by 20 % than comparable study which however uses data that are not usually available. Models can be used in waste management and their simplicity is benefit for real usage.

Analysis of Municipal Solid Waste Treatment Possibilities in Microregion
Ucekaj, Vladimír ; Ochodek, Tadeáš (referee) ; Klemeš,, Jiri (referee) ; Bébar, Ladislav (advisor)
n accordance with Council Directive 1999/31/EC implemented by Regulation number 294/2005 Sb., Czech Republic has agreed to reduce landfilling of biodegradable material contained in mixed municipal waste (BDMW) by 50 % in comparison with 1995 starting January 1, 2013. This causes several problems to municipalities as the issue of mixed municipal waste (MMW) treatment is not handled at any level of state administration. PhD thesis tackles the question which level of state administration - national, regional, or microregional or municipal - should be responsible for waste treatment and whether it is economical and efficient, or not.

Experimental reactors for combustion of biomass and municipal solid waste
Bialožyt, Michal ; Juřena, Tomáš (referee) ; Recman, Milan (advisor)
The main purpose of this thesis is background research about experimental reactors for combustion process research. Mainly semted on reactors with fixed bed for alternative fuels, such as biomass and municipal solid waste. Mathematical modeling of the combustion process with modern software products and its optimalization is not possible without input data gathering from these facilities. Thesis should serve as a source of information for building a new experimental reactor.
