Modeling the Impacts of Changes in Waste Management on Key Technologies
Jadrný, Josef ; Suzová, Jana (referee) ; Weidlich, Tomáš (referee) ; Pavlas, Martin (advisor)
The doctoral thesis focuses on waste management planning in the Czech Republic with regard to key technologies. The operation of processing facilities is influenced by strategic documents that reflect the legislative framework of the EU and the Czech Republic. Due to the introduction of new principles and evaluation criteria, it is necessary to regularly update the Waste Management Plan at the state and regional level, according to the Waste Act No. 541/2020 Coll. When creating new strategic documents, emphasis should be placed on the use of available computing tools, inter-regional cooperation and the specific formulation of goals and measures. The individual goals of waste management must be taken into account when operating existing facilities and also when planning the necessary infrastructure. The attention in this text is devoted to the analysis of the current state of waste management in the Liberec Region with a focus on key technologies. The mentioned approaches and recommendations can be further applied to any region of the Czech Republic.

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.

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.

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.

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.

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.

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.

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.

Analýza odpadového hospodářství ve vybrané obci
Škrobánková, Sára
The presented diploma thesis deals with the analysis of waste management in the city of Brno. The introductory part focuses on legal regulations that are related to the problematics of waste generated in the territory of the municipality. Furthermore, the work presents global, European and national trends in the management of municipal waste, the collection network and the costs of waste management within the Czech Republic. In the practical part are evaluated demographic conditions of the city, fulfillment of selected legal requirements of the relevant legislation, efficiency, collection systems, production of individual wastes and their management, economy of waste management and carbon footprint of wastes. Subsequently, a SWOT analysis of the city's waste management was also done. Based on the results, a discussion was written, and suggested measures were written as well to improve the current waste management system. The performed analyzes are processed in charts and tables for better clarity.

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.
