Post-consumer packaging waste production
Pálešová, Lenka ; Gregor, Jiří (referee) ; Pavlas, Martin (advisor)
This bachelor´s thesis covers waste and packaging legislation of Czech and Slovak Republic. It focuses mainly on the latest changes in area of plastic packaging and on the implementation of European directives. Furthermore, it compares authorized packaging companies, that perform extended producers´ responsibilities in both countries, and explains the principles of eco modulation. The work itself is linked with project announced by Centrum of environmental research for waste management and circular economy and is supplemented by practical part, which consists of various phases: analysis of waste production at home and in the field, preparation of document materials and processing the data obtained from analysis.

Models for network flow identification
Smejkalová, Veronika ; Kůdela, Jakub (referee) ; Pavlas, Martin (advisor)
The bachelor thesis is focused on development of a mathematical model of network flow in waste managment. The theoretical part of thesis deals with graph theory, network flow and optimization. The next chapter introduces the mathematical model. The model was compiled with the use of Information systems of waste management. The data are very often burdened by error. The task of the model is revelation of those errors to make the data useful. This thesis also includes suggestions for further development.

Technical-economic models of waste-to-energy plants
Čech, Martin ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Main principle of the thesis is to create technical-economic model of municipal waste-to-energy plant. This model is suitable for different technical parameters of various incinerators and there is not necessary to create new model for each new incinerator. The model also includes basic economic aspects of technology and service of the municipal waste incinerator. The importance of municipal waste incinerator construction, their current situation and planned future in Czech Republic are also mentioned in the thesis.

Network flow models for waste management
Janošťák, František ; Mrázková, Eva (referee) ; Pavlas, Martin (advisor)
This thesis is devoted to the construction of new waste-to-energy plants in a territory where is already another fossil-fuel power station in operation. The aim is to create a mathematical model and prove that those two devices are able to cooperate effectively using same technology. Exactly assembled model under real operating have characteristics of a mixed integer nonlinear programming. The optimization software GAMS is used for its calculation. The complexity of the model, however, is at a level that solutions in bad initial conditions ends in local optima, or not found at all. This thesis is devoted to the elimination of non-linearity using binary variables and heuristic so the task was solved with acceptable time limits to guarantee an optimal solution.

Risk modelling in transportation
Lipovský, Tomáš ; Pavlas, Martin (referee) ; Popela, Pavel (advisor)
This thesis deals with theoretical basics of risk modelling in transportation and optimization using aggregated traffic data. In this thesis is suggested the procedure and implemented the application solving network problem of shortest path between geographical points. The thesis includes method for special paths evaluation depending on the frequency of traffic incidents based on real historical data. The thesis also includes a~graphical interface for presentation of the achieved results.

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.

Ballance of waste to energy process
Hejl, Matěj ; Bébar, Ladislav (referee) ; Pavlas, Martin (advisor)
This diploma thesis considers different attitudes to evaluation of lower heating value of municipal solid waste as a main parameter of calculation of effectiveness incineration process. Modification of general relation is done to calculate lower heating value by using methodology BREF/BAT for real plant. The next step is evaluation of lower heating value within measured data. Following part of this thesis is focused on establishing thermal efficiency of incineration boiler by using direct, indirect and “modified” indirect methods and statistical analyses of them. Analysis of important quantities, which enters the calculation of thermal efficiency, is realized. The establishment of measurement error in measuring these main parameters is done as well.

Secondary materials from household waste and their position in the global market
Tesař, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The barchelor thesis is focused on the issues of material recovery of municipal waste. The work presents the basic concepts of waste management and resource data to help analyze the current virtual situation in the field of waste management. Work specifies the components with the greatest potential for material recovery. For the selected folder, which can be commonly referred to secondary raw materials, work tries to describe the flow of materials and meet with their potential application in the market.

Sustainable treatment of municipal solid waste
Lapáček, Milan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The bachelor thesis is focused on a particular type of waste – municipal waste. It´s engaged in a research of current production and in a way of treatment of the municipal waste in the Czech Republic. In the work it´s stated the basic ways of the waste treatment and it´s focused on the energy recovery of municipal waste. It´s introduced the basic data resources, which enabled to analyze the waste management. In other parts of the thesis it´s compared specific production and the ways of waste treatment in the Czech Republic with the ways of waste disposal in other countries of European Union, especially Germany.
