The effect of dump waters on the quality of surface stream in Czech Republic
Samšuková, Eva ; Benešová, Libuše (advisor) ; Křenková, Marcela (referee)
A landfill leachate is a chemical solution generated in the waste materials that are dumped in a landfill. According to the increasing amount of waste produced worldwide the risk that leachate water gets out of a landfill and contaminates with contained pollutants surrounding environment, e.g. nearby surface water, rises. The aim of this thesis is to evaluate the effect that leachates have to surface water in the Czech Republic. The research was built on primary data that had been obtained in several landfills in the Czech Republic. Important sources were also obtained through the secondary literature. Possible influence of leachates is also outlined by chemical calculating illustrating a hypothetical situation of leaking landfill water to a stream. My research showed that the impact of landfill water on surface water presents a great risk. It can occur during ordinary operations of the landfill operations - due to instable technical installation or due to dumping waste with a different extract conditions, but also as a consequence of extraordinary situations (e. g. storms). Surface water is mostly polluted with heavy metals, chlorides or nitrogen in variety of its forms. High concentration of organic matters is also detected by COD and BOD indicators. Exceeding legal limits threatens the whole surface...

Food Waste in the United States as an Issue of Federal Public Policy Making
Hlaváčková, Anna ; Sehnálková, Jana (advisor) ; Kozák, Kryštof (referee)
The Master's thesis "Food Waste in the United States as an Issue of Federal Public Policy Making" analyzes the role of the federal government in dealing with food waste. It mainly focuses on federal legislation, but it also examines actions on the state level to illustrate the contrast between the two. In the thesis, the author examines the causes and sources of food waste, federal jurisdiction for intervention, and the history of passed legislation, as well as proposed legislation, and solutions. The main goal of the thesis is to demonstrate that federal involvement is fundamental in achieving any significant change, but so far has failed to do so. Primary literature consisting largely of bills, materials published by federal agencies, and reports by non-profit organizations were used to uncover the character of passed legislation. Academic secondary literature in the form of articles, reports, and factsheets offered context to understand the scope and impacts of the legislation. Analysis of those sources revealed federal authority to deal with the issue, as well as possible obstacles standing in the way of an extensive federal intervention. Research also showed that in the absence of federal action, some states have stepped up to introduce legislation to reduce food waste, but this legislation is...

Assessment of suitability MSW landfilling in the Czech Republic
Kosová, Kristýna ; Benešová, Libuše (advisor) ; Kotoulová, Zdenka (referee)
The paper examines the suitability of municipal waste landfill in the Czech Republic. Landfill is still the most common method of waste disposal. This is mainly due to the number of landfills in the country, the level of charges, poorly built infrastructure capacity and other technical facilities for waste management. The work deals with the actual construction of landfill, through the production, collection and sorting MSW to the political and economic waste management. It also focusing on current issues of legislation and waste management. Part of this work is survey of public opinion and proffesional's views on this issue, which is divided to supporters and opponents. Although the landfill haves still a decreasing trend, the fact remains that there will be always stay some residual waste that can not to be completly remove. So the landfill will always remain as integral part of waste management.

Analysis of engineering geological and geotechnical conditions in the MSW landfill Úholičky
Matoušová, Jana ; Kudrna, Zdeněk (advisor) ; Rout, Jiří (referee)
This thesis analyzes the engineering-geological and geotechnical conditions MSW landfills in Úholičky. It includes the methodology of field mapping and documentation work, evaluation of natural conditions the area of interest, the assessment of geotechnical properties of rocks and soils and geotechnical conditions at the landfill and finally deals with risk analysis MSW landfill in Úholičky. At the same thesis includes a search of domestic and foreign literature. The outcome of their work is the engineering map, evaluation and interpretation of the data from the MSW landfill settlement Úholičky. This interpretation has use for further progress of the construction landfill. Powered by TCPDF (www.tcpdf.org)

Modern alternate types of sealing barriers analysis for landfills
Matoušová, Jana ; Sedláček, Jaroslav (referee) ; Kudrna, Zdeněk (advisor)
People and waste on our planet is constantly increasing, and so despite the unattractiveness topic the landfills are the current and noticeable issue. This paper deals with the standards and laws relating to landfills, from which they depend for the creation and construction. I should present an overview of the different variants of application materials to the construction of the landfill could be used, and today sealing landfills are available for engineers. But just I do not engage in alternative sealing options as well as standard which are still widely used methods of sealing landfills. To the situation in the Czech Republic stated in a global context, I give examples of coping with the landfill in other countries such as Chile, where they try to use local raw materials. What is landfill waste and security are concerned; our model may be one of our neighbours - Germany, which in this part is devoted to most extensively. Each of these options has its pros and cons. I leave at will and view of each reader to evaluate the advantages and disadvantages of each solution. It is also possible to adhere to the already proven and well used ways of depositing, in their modernized and improved form.

Quality control of biodegradable waste process
Krbalová, Maria ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The waste production and especially biodegradable waste is following mankind since the beginning of his existence. This thesis deals with a description and dividing of current available waste process technologies, including description of their advantages and disadvantages. The work is also focused on the more detailed description of the composting technology, its control and opportunities to influence on resulting parameters of compost product. The information about technical description of workplace equipments, including industrial and technological processes was provided by the company VIA ALTA from their compost plant in Blansko.

Secondary materials from household waste and their position in the global market
Tesař, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The barchelor thesis is focused on the issues of material recovery of municipal waste. The work presents the basic concepts of waste management and resource data to help analyze the current virtual situation in the field of waste management. Work specifies the components with the greatest potential for material recovery. For the selected folder, which can be commonly referred to secondary raw materials, work tries to describe the flow of materials and meet with their potential application in the market.
