Systematic approach for medical waste-to-energy processing
Hanus, Jan ; Krejčí, Tomáš (referee) ; Krňávek, Martin (advisor)
This master thesis deals with the current situation of medical waste management in the Czech Republic and available medical waste treatment methods. The first part summarises the legislation of waste treatment and contains an analysis of the current situation of medical waste management in the Czech Republic and comparison to the situation in the European Union. The second part describes medical waste treatment methods and following technologies for energy utilization when thermal treatment method is applied. In the main part of this thesis, a complex medical waste-to-energy system in a model region is designed according to the input data. The design includes description of the collecting and transportation system of the waste, capacity of the unit and suitable thermal treatment and heat utilization technology choice. A calculation model is created for the proposed unit and based on this model, an analysis on energy utilization effectivity is made. As a result of the thesis, environmental, technical and economical assessment is created based on the estimation of the investment and operating costs.

Effective Investment Planning in Waste-to-Energy Systems
Šomplák, Radovan ; Klemeš,, Jiří (referee) ; Žaloudík, Petr (referee) ; Stehlík, Petr (advisor)
PhD thesis deals with the application of the simulation and optimization methods in the waste-to-energy field. An introduction describes the current state of the waste management in the EU with the focus on the Czech Republic. In the following chapter the evaluation criteria for investment intentions and the basic principles of stochastic programming are discussed. The core of the work lays in the mathematical models for the planning and operation of the process plants as well as in the mathematical models for the waste collection. The transportation problem involves all considered technological elements and therefore it is possible to simulate the waste streams between the producers and processors. This approach is demonstrated with five case studies. In the first three studies the calculations for the potential investor are presented. The main outcome of these case studies is the determination of the level of attractiveness of investment and the identification the greatest risks. Another case study is devoted to an analysis with the focus on perspective of government policies and in the last case study the issue of the waste management is analyzed in detail from the perspective of the waste producers. Developed computational tools are flexible and can be further developed and adapted based on the objectives of the specific tasks.

Technical-economic models of waste-to-energy plants
Čech, Martin ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Main principle of the thesis is to create technical-economic model of municipal waste-to-energy plant. This model is suitable for different technical parameters of various incinerators and there is not necessary to create new model for each new incinerator. The model also includes basic economic aspects of technology and service of the municipal waste incinerator. The importance of municipal waste incinerator construction, their current situation and planned future in Czech Republic are also mentioned in the thesis.
