Advanced Logistic Models for Waste Management
Gregor, Jiří ; Jegla, Zdeněk (referee) ; Pospíšil,, Karel (referee) ; Stehlík, Petr (advisor)
The purpose of the dissertation thesis is to prepare transport techno-economic models which will be able to estimate the transportation cost for selected scenarios. The main goal is to describe the complex transport chains in waste management, using different types of transportation (road, rail) and transport different types of waste. The key element of preparing techno-economic models is the identification of input parameters which are important for estimating the cost of transport. At the same time, it is necessary to correctly identify the processing facilities that will be part of complex transport chains. The total outputs will be presented in the form of a feasibility study.

Regional Characteristics of Municipal Waste
Švarc, Vít ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
This thesis describes the current state of waste management in Czech Republic and assesses the impact of small businesses on the production of municipal waste in various Czech regions. The main objective of this thesis is to create a model of production of municipal waste with a focus on so-called commercial waste or an industrial waste, which is part of the waste, produced from municipal waste management systems. The work is based on statistical data of municipal waste production, statistics on the representation of small-scale industries of the Czech municipalities, and uses correlative and regressive analyses.

Transportation systems in waste management
Koutná, Marie ; Pavlas, Martin (referee) ; Gregor, Jiří (advisor)
The aim of the thesis is to elaborate on transport systems in waste management as they represent a key part of the waste management process. Its theoretical part covers legislation in waste management and sorts and systems of household waste collection. In the practical part there are commercially used vehicles chosen out and the fixed costs of their operation determined. Based on operation data, average velocities in an out of urban areas are calculated. As an outcome of a waste transport prices software, the influence of transport distance and waste mass are described, taking the average velocities into account.

Rail transport in practice
Poul, David ; Pluskal, Jaroslav (referee) ; Gregor, Jiří (advisor)
The diploma thesis deals with railway transport describes its role in combined transport and compare key aspects with road transport. As part of the diploma thesis, a detailed database of railway tracks in the Czech Republic was created, on which the route planner was built with the possibility of setting waypoints. The route planner also includes the implementation of exclusion activities. A comprehensive technical-economic model of railway transport was created with four calculation models and detailed investment planning, thanks to which is possible to assess whether the purchase or lease of train sets is more advantageous when making investment decisions. Furthermore, a technical-economic model for the branch line was created. The last section deals with the created transport model for the catchment area for 8 localities and 5 types of transported waste/commodities. The transport model was used to evaluate two selected areas – the South Moravian Region and Kolín.

Construction of boom of loader Dapper
Gregor, Jiří ; Petráš, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the analysis of the current kinematic mechanism of the DAPPER 5000 boom. The second part of the thesis deals with the new mechanism design. The new solution is also analysed kinematically and forcefully. The first part of the thesis is devoted to a description of the DAPPER 5000 and its parts. It is followed by a description of its boom, its analysis and comparison with the booms of competitive loaders. After a critical review of the various boom concepts, where their suitability for the DAPPER 5000 is assessed, a new mechanism for the DAPPER boom is designed. This is followed by a detailed analysis of this mechanism, a basic strength check and, in conclusion, the results of the analyses are summarized, and the meaningfulness of this structural change is evaluated.

Emerging systems of collection in waste management
Petrasová, Zuzana ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The main aim of the thesis is a description of the methods used in the collection of waste with a focus on non-traditional ways. Its part is the outline of a basic technical specification of the methods. The analysis is further used to determine the technical-economic model for underground waste containers, which is able to calculate the construction costs based on given values. The model is designed for containers of three different volumes and is the main result of the thesis. The knowledge of input investments is being used to compare the economic demand and the potential return of investments with regards to the traditional collecting methods (bins, containers) and the pneumatic underground system, whose estimated costs are taken from foreign models.

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.

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.

Recycling plants in the Czech Republic
Průžková, Kateřina ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
This bachelor thesis is focused on recycling the municipal waste components (glass, paper, plastic). First part of the thesis contains a research into the current state of the waste management and its collection technologies. The following chapter consists in description of the waste components, their recycling and utilization as secondary raw materials including resource efficiency during the plastic recycling. The next part of the work comprises the list of recycling plants, which is sorted by the type of the waste processed. A separate chapter is focused on the technology of the plastic processing recycling line and its energy intensity. Subsequently, the cost of this recycling line and its components is introduced.
