District heating systems in the Czech Republic in the context of legislative changes
Hylas, Martin ; Poul, David (referee) ; Putna, Ondřej (advisor)
The bachelor thesis focuses on the analysis of the issue of district heating (DH) with regard to legislative changes in the European Union. The first part deals with the analysis of the issue and the evaluation of the state of CZT in the Czech Republic. The European Union's position on climate change, caused by increasing greenhouse gas emissions, which are significantly produced by DH sources, is also discussed. The research part ends with an analysis of possible changes in the heating industry leading to the fulfillment of legislative requirements in the future. The second part of the bachelor's thesis deals with the elaboration of a case study of the change of the fuel mix for the heat source in the existing locality with the use of the technical-economic model. The main goal is to evaluate the usability of renewable resources (biomass, waste) as primary fuels instead of natural gas. The result of the practical part is a comparison of individual variants and changes in the cost of producing 1 GJ of heat compared to the reference variant.

Waste-to-Energy as a key technology of developed waste management systems
Guštara, Dominik ; Putna, Ondřej (referee) ; Šomplák, Radovan (advisor)
Bachelor thesis focuses on analyzing the current state of European waste management systems and on prediction of its future development with focus on waste-to-energy technology. First part of this thesis serves as an introduction to the waste management issue and describes a computational tool NERUDA. Following is a description of data collection about the current state of waste management in the investigated countries. The final and most important part deals with the explanation of how the future development was estimated and with analyzing the results of optimization.

Integration of Waste-to-Energy Plant into the District Heating Network with Existing Heating Plant
Kopecký, Václav ; Janošťák, František (referee) ; Putna, Ondřej (advisor)
The main two goals of this thesis are summarization of current state of waste management policies in the Czech Republic and introduction of possibilities connected with waste-to-energy strategy. This thesis is divided to 4~sections, each of them focused around different part of this complex problem, or issues directly connected to it. In the first part, state of waste management in the Czech Republic is discussed from several different points of view. Then, district heating is introduced as a solid platform for waste-to-energy facilities. The last two chapters present several other issues, connected with construction of new waste-to-energy plants and methods of optimization of long term rentability models.

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.

Evaluation of cogeneration units in Waste-to-Energy plants
Chýlek, Martin ; Putna, Ondřej (referee) ; Ferdan, Tomáš (advisor)
The purpose of this bachelor thesis is familiarization with legislation of evaluating combined heat and power generation systems and discover it´s questionable spots. Another objective is to make universal model of incineration plant and to apply calculation mentioned in legislation on various options of technology. The end of thesis is devoted to analysis of results.

EFFECTIVE UTILIZATION OF MUNICIPAL SOLID WASTE IN HEAT AND POWER SYSTEMS
Putna, Ondřej ; Klemeš, Jiří (referee) ; Ucekaj, Vladimír (referee) ; Stehlík, Petr (advisor)
The dissertation thesis is focused on the issue of energy recovery of waste. It contributes to optimization models developed in the author's workplace in the long term, which serve to simulate material flows in waste management and to search for an optimal waste management strategy. The main objective is to assess the potential for the use of heat produced in waste-to-energy plants as a key factor for the economy of these facilities. The thesis therefore represents an activity on the border of the fields of waste management and heating. Partial mathematical models were developed within the scope, for which it was necessary to collect input data, especially in relation with district heating networks. These models were then used in a comprehensive optimization model describing the integration of waste-to-energy plants with other heat sources. This main model was extended to include the environmental aspect.

Potential of energy production from waste
Putna, Ondřej ; Ferdan, Tomáš (referee) ; Touš, Michal (advisor)
The main topic of the bachelor thesis is creating energy from the incineration of waste. In the first part, the current situation of waste management of the Czech Republic and other states of the Europian Union is outlined. Then the thesis is focused on waste incineration in waste-to-energy plants and various approaches of energy efficiency evaluation are described. In the second part, energy efficiency with various modes of thermal and electrical energy production is analyzed, using the model of WtE plant. In conclusion, obtained data of energy efficiencies are compared with conventional energy sources.

Regional energetic waste exploitation
Krňávek, Martin ; Putna, Ondřej (referee) ; Bébar, Ladislav (advisor)
The master’s thesis deals with technologies for energy utilisation of waste with annual treatment capacity approximately from 10 to 50 kt/year and their application in regions of the Czech Republic. In the first part of the thesis the results of heat consumption analysis in seven regions of the CR are introduced while in two selected regions a production of waste was analyzed too. The main part deals with the design of technological solution of waste-to-energy plant with medium capacity and its integration to specific conditions of the two selected regions. Alternatives of combined heat supply were assessed from waste-to-energy plant as well. A basic economic analysis that contains the estimates of incomes and capital expenditures and operating expense is a part of this thesis too.

Effective methods for mechanical treatment of waste
Harnová, Veronika ; Putna, Ondřej (referee) ; Kropáč, Jiří (advisor)
The aim of the Bachelor's thesis is the description and technical-economic evaluation of Czech municipal waste management and sorting lines operation. The main part of the thesis consists of a description of choices of automatic sorting systems in sorting lines operation. The most important part is the analysis of alternative municipal waste collection containers with respect to different settings of manual or automatic sorting lines.
