Sink disposers and theirs importance in biological degradable waste removal.
Amemori, Anna ; Benešová, Libuše (advisor) ; Doležalová, Markéta (referee)
Some 30 - 50 % of municipal solid waste (MSW) is biodegradable waste. Most of this waste is sent to landfills or incinerated and is not recovered. According to Waste Management Plan of Czech Republic based on the Landfill Directive of EU, Czech Republic should to reduce weight of biodegradable waste sent to lanndfills to 75 % in 2010 and 35 % in 2020 compared with the amount that had been landfilled in 1995. In rural areas biodegradable waste is fed to animals or treated by home composting. However in urban areas the collection of separated biowaste is problem for a long time. Food waste disposers (FWDs) presents interesting alternative for the biowaste disposal. They enable the separation of food waste at source by shreding it in a kitchen sink. FWDs utilize existing infrastructure of sewer system to transport shreded wastes to wastewater treatment plants (WWTP). Wastes can be disposed in WWTPs by anaerobic digestion - the best method for disposal of food waste of animal origin. This work concentrates on literature research of studies about feasibility of FWD as a instrument for biodegradable waste removal and compares arguments for and against using of FWDs in households. Majority of studies shows no complications in sewer system and on WWTP after instalation of FWDs. Energetic and hydraulic consumption...

Roberto Saviano's Gomorrah. Reality and fiction
Bursíková, Martina ; Flemrová, Alice (advisor) ; Pelán, Jiří (referee)
This thesis focuses on the selected topics of Roberto Saviano's Gomorrah and it attempts to examine the way the author works with facts and how he presents them. In the introductory chapter I gave an outline of Saviano's work and of the general characteristics of his literary style, his processing of facts and work with them and the main topics of his writings. In the beginning of my thesis, I addressed the topic of a literary style called the New Journalism. I presented its main ideas, representatives, literary goals and the core points of its manifesto. When assessing Saviano's work in the context of New Journalism, I believe it is crutial to consider its objectivity, genuine capture of reality and its comprehensive approach to narration of facts with a literary language of aesthetic dimension. Saviano's only deflection from this style would be in his role of the narrator. New Journalism seeked to push the role of the narrator to the background or to have it absent altogether whereas Saviano often appears in his own plays as a direct participant or an indirect commentator. The view of the author, the participant or the characters did frequently appear in the works of New Journalism. The most common form, however, was to expound and describe the character through its' own mind - which makes the role of the...

Immobilization of heavy metals in the cement matrix with the admixture of natural zeolite
Semerádová, Nikol ; Bayer, Patrik (referee) ; Vyšvařil, Martin (advisor)
Heavy metals released to the natural ecosystem constitute significant risks not only for organisms, but also for water supplies in the nature. There are a number of analytical methods for the determination of heavy metals. Each of them is suitable for different element and its character. Since the results of the analysis are applied during the solidification and stabilization, it is necessary to ensure the highest correlation between hazardous waste and solidification medium for maximum inhibition of toxic ions. This work investigates the stabilization of heavy metals binders based on cement base with admixture of the natural zeolite and its possible use for the solidification of heavy metals in soluble form.

Comparison of economic and environmental aspects of waste management in selected municipalities of different sizes
HAVLOVÁ, Marie
The industrial development of our society pushes waste management into becoming an important part of both the economy as well as the environmental protection. It is essential to reduce the amount of waste which is being deposited in landfills without any further use. In the next 10 years it is necessary to completely eliminate waste disposal of the reusable waste and especially of the mixed municipal waste. This thesis focuses on the waste management of various types of municipalities. It aims to provide optimization of waste management, in the connection with economical and technical possibilities of various types of municipalities. This thesis is divided into two parts. The theoretical part describes the issue of waste management in the course of history. It shows the various methods of waste disposal and describes the economic and environmental aspects and impacts in general. It briefly summarizes the development of waste management legislation. The second part of this thesis is focused on the analysis of waste management in selected municipalities. Twelve towns in three groups of different sizes were chosen. A survey of waste disposal and the influence of the size of the town and its technical options on the waste management was conducted. The results showed that municipalities have substantial reserves in reducing the amount of waste going to landfill and also in the practical use of waste sorting. In the conclusion of this thesis suggestions to optimization of waste disposal are being presented.

Sustainable treatment of municipal solid waste
Lapáček, Milan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The bachelor thesis is focused on a particular type of waste – municipal waste. It´s engaged in a research of current production and in a way of treatment of the municipal waste in the Czech Republic. In the work it´s stated the basic ways of the waste treatment and it´s focused on the energy recovery of municipal waste. It´s introduced the basic data resources, which enabled to analyze the waste management. In other parts of the thesis it´s compared specific production and the ways of waste treatment in the Czech Republic with the ways of waste disposal in other countries of European Union, especially Germany.

Modelování THM procesů v horninách
Blaheta, Radim ; Kohut, Roman ; Neytcheva, M. ; Starý, Jiří
This paper is devoted to medelling thermal (T), hydraulic (H) and mechanical (M) processes in rocks.These physical processes seem to be most important ones for many engineering applications ranging from the classical mining, tunelling and underground constructions to new geotechnologies of waste disposal or geothermal anergy utilization.
