Development of chemically resistant tile grout containing secondary raw materials
Matušková, Veronika ; Seidlová,, Michaela (referee) ; Drochytka, Rostislav (advisor)
The aim of the diploma thesis is development and research of a high-quality polymeric jointing grout material using secondary raw materials and hazardous waste for extreme chemical exposure. The main intended use of the developed grout joint is grouting of the cast basalt elements in building objects that are permanently expose to highly aggressive chemical environment. The use of input materials produced by progressive technologies should be another benefit of this grout joint to enhance ecological aspects of a grout joint production.
Waste management within the public infrastructure of the selected municipality
The bachelor thesis deals with the analysis of waste management in the selected municipality. The theoretical part contains the basic concepts in the field of waste management, legislation, collection possibilities, methods of waste management and disposal. The practical part deals with the analysis of waste management in the municipality of Pacov. The bachelor thesis specify the amount of the waste produced and compares them in the monitored years. It is also dedicated to working with companies that provide repurchase of electrical equipment. The conclusion is an evaluation of the current state of waste in the monitored area, possible proposals and recommendations for eventually improvement of waste management.

The work deals with the development of new polymeric coatings and screeds – epoxy, polyurethane and vinyl ester materials with the use of hazardous waste in the form of fillers. The areas that are destined for their landfill are constantly expanding and the costs of disposing of this waste are high. Their use eliminates negative impacts on the environment, but also leads to significant financial savings. The aim of this PhD thesis was to find a suitable way to treat selected hazardous waste and experimentally verify the possibilities of using the fillers pre-treated by optimal way in polymer coatings and screeds. The coatings and screeds are intended primarily for concrete substrates but the possibility of use on metal substrates, asphalt and cement-bonded particle boards was also been verified. These materials serve as a secondary protection of structures against the adverse effects of weather conditions. Secondary raw materials were used as fillers, which were fluidized bed combustion fly ash contaminated due to flue gas denitrification and specially pre-treated hazardous waste (solidification products). The aim was to proceed progressive use of the secondary raw materials as much as possible in order to reduce landfilling in the maximum possible way. It was necessary to treat hazardous waste in such a way that the most effective solidification would be achieved. The behavior of the solidifaction products in the polymer matrix, the distribution of particles in the structure and the disruption of coatings and screeds due to chemical stress were also investigated.
The study of occurrence, collection and disposal of hazardous waste
Wolf, Adam ; Benešová, Libuše (advisor) ; Zimová, Magdalena (referee)
This bachelor thesis provides an overview about the hazardous waste. At the beginning there will be discussed the legislative measures related to hazardous waste management and international cooperation. Following three chapters are dedicated to these hazardous wastes: asbestos waste, sludge from wastewater treatment and ashes from incineration waste. Today forbidden material asbestos occurs in insulation of the old public and industrial buildings. It is essential to prevent release of asbestos fibres. Further currently was proposed several promising processes for treatment of sewage sludge and ashes from incineration waste that management in the Czech Republic overlooks. Presented methods emphasize degradation of hazardous properties from the concerned waste. Thesis shows current occurrence of waste in environment. Main objective is assessment of potential risks for human health or environmental components, consequent from hazardous waste and draw implications for the most effective treatment. A conclusion of literature research summarized advice for treatment of these waste. Key words: hazardous waste, hazardous properties, asbestos containing waste, sludge from wastewater treatment, sewage sludge, waste incineration, bottom and fly ash, vitrification, heavy metals.
Handling with hazardous materials on construction site
Máčaiová, Klaudia ; Biolek, Vojtěch (referee) ; Tuscher, Martin (advisor)
The aim of the diploma thesis was to point out possible legislative differences between the Czech and Slovak Republics and to provide examples of asbestos disposal prices. The theoretical part briefly summarizes the waste, it is legislation and the share of construction waste. The chapter entitled Asbestos provides a brief overview of the history, mining and diseases caused by asbestos. In the practical part I devote with the legislative methodology of asbestos disposal according to the Czech Republic. Based on the relevant laws in the states, I subsequently evaluated the differences between the countries. I also devote with the procedure of disposal of sewer pipes and roofs, for which I subsequently created a budget with reference to the price of asbestos disposal.
Development of new chemically resistant coating system containing secondary raw materials
Stodolovská, Šárka ; Jakubík, Aleš (referee) ; Drochytka, Rostislav (advisor)
New types of highly chemically resistant coating systems, primarily designed for concrete and metal substrates are designed and experimentally verified within the diploma thesis. Secondary raw materials, including solidified hazardous waste, are used as microfillers. The developed coating system is solved in two quality levels – PREMIUM and ECOLOGY. The level of PREMIUM is mainly designed for environments where extreme chemical stress is occurring. The polymer coating systém ECOLOGY can be used in environments where aggressive chemical media also act, however the ecological foot of the input raw materials is most important. The diploma thesis is dealing with current issues in the practice and it is the part of the research project.
