Design of Sludge Disintegration Unit
Brtna, Filip ; Beňo, Zdeněk (referee) ; Boráň, Jaroslav (advisor)
The target of the first part of this diploma thesis is focused on the problems relating to the sludge production from the wastewater treatment plant and subsequent sludge treatment. In this thesis complete process of the wastewater treatment is described. Predominantingly is described the process in digestion tanks, therefore stabilization process, whereas the paper is focused on sludge pre-treatment (disintegration) of waste activated sludge before stabilization. The second part of this thesis is focused on the design of the disintegration unit for the wastewater treatment sludge in assist with experimental data. According to measured and fixed parameters the unfired pressure vessel has been designed. On the vessel has been further realized the strength calculation, the heat balance and the economic balance.

Nakládání s potravinovým odpadem
Voznicová, Eliška
This bachelor’s thesis focuses on food waste management, which is closely related to global climate change, overpopulation and food waste. The aim of this thesis is to complete legislative regulations related to this topic and to define how food waste is categorized and at that stage, food is discarded. This thesis also deals with selected processing and mentions sustainable food consumption and food labelling. The research used a mapping method to verify whether gastronomic establishments comply with legal regulations and have designated special containers for food waste and waste collection companies. Another method used was an interview with a freegan and subsequently with a gastronomic establishment employee. The mapping research revealed that an unsuitable time was chosen for the mapping. The main finding from the interviews was that some gastronomic establishments are open to new trends in reducing food waste. Despite increasing demands for legislative regulations on food waste disposal, the main takeaway from the interviews was that it is possible to consume only discarded food.

Legislation of handling of special sources of danger to the environment
Michálková, Tereza ; Stejskal, Vojtěch (advisor) ; Pekárek, Milan (referee) ; Sobotka, Michal (referee)
Thesis "Legislation of handling of sources of danger to the environment" Abstract The thesis deals with material sources of danger to the environment in terms of legal forms of environmental protection from negative impact of these sources. The topic was narrowed at the beginning of the thesis to waste and chemicals so now it represents these two huge and significant groups of threats to the environment. The reason to narrow the topic was existence of a very large scale of different sources of environmental danger and that could cause shattering of the topic during writing the thesis. The thesis describes in individual chapters various forms of waste and chemicals handling in mutual relationship with legal obligations of subjects of law. The thesis at the same time attempts to evaluate valid legislation in terms of sufficiency of legal obligations and whether these obligations are clear and specific enough to enable high level of protection of the environment and human health (at least). Czech waste management legislation is massively influenced by directive of European union waste law, so the thesis compares intention of union legislator (if it is available) with the results of czech transposition. The waste and chemicals handling chapters are connected with supporting chapter about various forms of legal...
