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.
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.
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.
Similar solution identification in the field of stochastic simulation related to waste management
Gal, Pavel ; Frýba, Lukáš (referee) ; Šomplák, Radovan (advisor)
The Master’s thesis deals with the issue of collecting mixed municipal waste from producers to a~waste-to-energy or landfills. The initial chapters are aimed to waste legislation and transportation of the waste by road freight transport across Europe. The objective is to collect the data, that are required for calculation in tool NERUDA. The next part describes the cluster analysis and different approaches in it. The selected methods of cluster analysis are apllied to the logistic task in the final chapters. The cluster analysis is considered from different aspects. The results are visualized using the software ArcGIS.
Waste management system sustainability
Bravený, Adam ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
The thesis proposes a new approach to assess sustainability of waste management systems. In the first part current mixed municipal waste (MSW) management system of the Czech republic is reviewed and promising MSW treatment techniques are introduced. In the second part a summary of literature on Life Cycle Assessment (LCA) approach to assess sustainability of MSW systems is provided. A new sustainability assessment model is proposed by implementing LCA to a current tool called NERUDA used to optimize waste management costing. It is demonstrated how to connect these two concepts in order to aquire a powerful tool for sustainability assessment.
Household waste transport
Gal, Pavel ; Frýba, Lukáš (referee) ; Pavlas, Martin (advisor)
Bachelor's thesis deals with issue of collection of mixed municipal waste to waste-to-energy. The main part is aimed to transportation of waste using rail freight or road freight transport. It shows the advantages of rail transport and compares transport in term of emissions and economy. The final chapter deals with preparation data for optimization problem and visualization of them using software ArcGIS.
Analysis of biodegradable communal waste disposal system in the city of Zlín
Přikrylová, Jana ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
This thesis discusses the disposal of the biodegradable communal waste (hereinafter BRKO) in the city of Zlín. In the beginning it introduces the general terms and keywords and legal regulations concerning waste disposal. It mentions environmental effects of the BRKO dump, and also ways of collecting and further treatment of BRKO. The main part of the thesis describes the current BRKO management system in the city of Zlín and based on the projects that have been completed up until now it analyses management efficiency. The thesis shows an expected progression in the total amount of BRKO in the following years due to the new limits placed on BRKO dump by the Plan of Waste Management Program. Based on the collected data, this thesis proposes an optimal solution for waste collection and waste treatment in the city of Zlín and evaluates the environmental and economic benefits of the suggested waste management system.
Life Cycle Assessment (LCA) of Mixed Municipal Waste Collected in Frýdek-Místek
Hamšíková, Renata ; Remtová, Květa (advisor) ; Hadrabová, Alena (referee)
Diploma graduation thesis deals with analytical tool called Life Cycle Assessment (LCA). Paper explains this analytic tool and focuses on its possible application in municipal decision-making process. Thesis carries out specific application of Life Cycle Assessment (LCA) targeted towards disposal of mixed municipal waste collected from Frýdek-Místek city. Municipal waste management issues are mentioned in relation with Frýdek-Místek and year 2007. The aim is to analyze nowadays landfilling of mixed municipal waste done in Frýdek-Místek and to examine the possibility of incineration of mixed municipal waste in order to reach minimal total environmental impacts. The paper offers improvement suggestions based on extensive LCA study.
