Možnosti kompostování biologicky rozložitelných komunálních odpadů v Adamově
Jordánková, Kateřina
This diploma thesis comes out of legislative requirements for a decrease in the quantity of biologically decomposable communal waste put in disposal sites and the support of composting. The thesis is focused primarily on making a draft of gathering and collecting biologically decomposable waste, its processing by composting and a draft project on a composting plant in the conditions of Adamov city. The plan of the whole system was set on the basis of the specification of the source of biologically decomposable communal waste and its weight flow depending on the type of a built-up area, evaluation of contemporary used technologies of composting with regard to the quantity of processed waste.
The influence of energy mix on environmental impacts of waste management
Dočekalová, Veronika ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
This paper presents energy mix of Czech Republic and its effects on environmental impacts of waste management. Three technologies: landfilling without energy recovery and landfilling and incineration with energy recovery are assessed using LCA. Results for 1 t of mixed municipal waste are compared in 9 impact categories: abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, photochemical ozone creation, human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity. Landfilling without energy recovery was evaluated as the most harmful technology to the environment, incineration as the most environmentally-friendly one. The use of Czech energy mix made impacts of the energy recovery technologies look lower, contrary to burdens of landfill without energy recovery that resulted higher. The influence of energy mix composition change is discussed further.
Refuse Derived Fuel
Exnerová, Anežka ; Kalivodová, Markéta (referee) ; Lachman, Jakub (advisor)
This bachelor’s thesis deals with the Waste-to-Energy topic focusing on refuse derived fuels. The aim of the first part is to describe what refuse derived fuels are, what are their properties and composition. From this point of view, we determine a comparison with municipal solid waste. Second part is about production process. Possible parameters of refuse derived fuels and the technological process of mechanical-biological treatment are presented here. Following part is focused on fuel combustion. This chapter lists combustion plants and emissions from the incineration of waste and refuse derived fuel.
Influence of socio-economic factors on the composition of waste: statistical approach
Jordánová, Petra ; Pavlas, Martin (referee) ; Šomplák, Radovan (advisor)
This bachelor thesis deals with comparison of mixed municipal waste in different areas in the Czech Republic. Statistical apparatus needed for subsequent data is described in the first part. There is discussed problematics of random variable, the probability distribution and hypotheses that will be used in this work. The second part involves a data set analysis. The merit of this thesis is hypothesis testing of the difference in mixed municipal waste composition between chosen areas and built-up area types. At the end an approach for estimate of impact factors of waste composition using correlation and regression analysis will be given. This work brings a benefit in current stratification evaluation process and recommendation of changes in selected factors.
Analýza složení komunálního odpadu se zaměřením na využitelné složky v regionu Moravskotřebovska
Valenta, Leoš
The bachelor thesis "Analysis of the composition of municipal waste with a focus on usable components in the Moravskotřebovsko region" aims to describe the valid legislative framework of municipal waste management according to valid regulations of the Czech Republic, region and municipalities. The following chapter is focused on the amount of mixed municipal waste production and the level of  its separation in the years from 2013 to 2016. The object of interest is 13 municipalities under the administration of Moravská Třebová Technical Services. The data was obtained through a questionnaire in municipalities, Technical Services Moravská Třebová and the Enviroment Department in the city office of Moravská Třebová. Furthermore, the data was transferred to per capita production and compared to municipalities in the Moravskotřebovsko region. A evaluation step of the high of the subsidy of the EKO-KOM system was made by recalculation to the population of the individual municipalities in the region. A final comparison was made between the Czech Republic and the selected region in the area of mixed and separate municipal waste components, such as paper, plastics and composite glass. The results, assessment of current state and suggestions to improve the present situation are at the end of the bachelor thesis.
Analysis of municipal solid waste in practice
Wildová, Kristýna ; Smejkalová, Veronika (referee) ; Gregor, Jiří (advisor)
The main purpose of the submitted diploma thesis is detailed research of studies and methodologies that deal with the analysis of the municipal waste composition, with focus on residual solid waste and transfer of acquired knowledge into practise. The research is focused on key parameters and procedures of studies and methodologies that took place in the Czech Republic, and also abroad. The identified information and procedures are properly summarized and evaluated. The theoretical findings were applied in the analysis of the municipal solid waste composition in a field work. The thesis is also focused on the practical feasibility of MSW analysis and related tasks. The data obtained during field work analysis of MSW are evaluated at the end of the thesis.
Analysis of Municipal Solid Waste Composition
Novák, Michal ; Kropáč, Jiří (referee) ; Šomplák, Radovan (advisor)
This diploma thesis provides extensive research of municipal solid waste studies and methodologies from all over the world. Firstly, the studies are described in general and then divided into several groups depending on the principle of their working practices, including their advantages and disadvantages. Secondly, the studies are divided by geographic areas. The results of the individual studies are presented and compared. Based on the findings in the thesis, appropriate methodology for municipal solid waste analysis in the Czech Republic is proposed.
Optimization models in waste management
Šmídová, Zlata ; Smejkalová, Veronika (referee) ; Šomplák, Radovan (advisor)
The master’s thesis deals with the application of optimization models in the waste management. The analysis of the current state, the estimation of information about the flow of a specific waste, the estimation of the probable processing site and the method of processing is developed by a suitable approach based on sophisticated mathematical methods. The mathematical model, which was created by merging the two already existing models, brings results suitable also for forecasting the state of the waste management. The output is a comprehensive computational tool that was tested on data from the year 2015. The results for mixed municipal waste (catalogue number 20 03 01), bulky waste (catalogue number 20 03 07) and waste with catalogue number 19 08 05, i.e. residual sludge from sewage plants, were processed in MS Excel.
Municipal waste composition and origin analysis for potential improvements
Kučera, David ; Kropáč, Jiří (referee) ; Nevrlý, Vlastimír (advisor)
The Bachelor’s thesis concerns analysis of composition and production of waste in households. It also introduces legal system regarding Czech municipal waste management and means of waste processing. Another part of the thesis consists of case study, which explains used methodology and describes collected data of selected waste types. The collected data on municipal waste production in Czech households are processed in MS Excel. The results of the statistical methods used for analysis show differences in production of individual municipal waste components in different types of households. The results also estimate the potential of municipal waste sorting.
Effective methods for mechanical treatment of waste
Harnová, Veronika ; Putna, Ondřej (referee) ; Kropáč, Jiří (advisor)
The aim of the Bachelor's thesis is the description and technical-economic evaluation of Czech municipal waste management and sorting lines operation. The main part of the thesis consists of a description of choices of automatic sorting systems in sorting lines operation. The most important part is the analysis of alternative municipal waste collection containers with respect to different settings of manual or automatic sorting lines.
