Replacing heat from fossil fuels by energy from waste
Ženatý, Sebastian ; Smejkalová, Veronika (referee) ; Putna, Ondřej (advisor)
This bachelor’s thesis deal with the topic of waste treatment and possibility of its energy utilization. Methods of waste treatment are presented in the introduction research part. It is mainly focused on the environmental impact. Subsequently it is concentrated on energy recovery facility, the environmental aspect of which is again the main focus. The practical part starts with a description of a tool suitable for modeling of heating and power plants networks. This tool is used for the calculation of specified heating network in the second practical section. Finally, the results are evaluated and the alternatives of the plant operation are proposed.

Importance of heat supply from waste-to-energy plants
Kopecký, Václav ; Janošťák, František (referee) ; Putna, Ondřej (advisor)
This thesis is focused on identifying main factors influencing economical rentability of energy generated using incineration of municipal waste. Research was conducted focusing on municipal waste management, waste-to-energy possibilities and the issue of district heating systems, which are important considering the economy of waste-to-energy plants. Main limiting factors were identified using mathematic models adjusted for specific geographic locations.

Waste management infrastructure in the context of European legislation
Arlet, David ; Putna, Ondřej (referee) ; Pluskal, Jaroslav (advisor)
This bachelor’s thesis aims to evaluate the contribution of waste management infrastructure and technologies that will play a part in the transition to circular economy. The introduction consists of the concept of circular economy and the European legislation on waste management. Furthermore it presents the waste management plan of the Czech Republic together with the methodology for reporting partial results and comparison of critical results with selected EU countries. The core of the thesis is an overview of the current processing infrastructure and potentially interesting new technologies that could help in the transition to a circular economy and thus achieve the ambitious objectives of the European Union. The outputs of the thesis can help to guide the future development of the waste management sector and thus provide a comprehensive insight into waste treatment issues, the objectives of which are mainly driven by European legislation in the context of set environmental milestones.

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.

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.
