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.
Estimation of municipal solid waste composition from the perspective of packaging
Doležalová, Adéla ; Putna, Ondřej (referee) ; Janošťák, František (advisor)
This master´s thesis focuses on prediction of presence of reusable material components in municipal waste with special focus on packaging materials. This prediction is based on analysis of financial costs of individual products according to the so-called market basket. Research of packaging´s life cycle and involving legislature is also a part of this thesis.
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.
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.
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.
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.
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.
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.
