Balanced approach in waste management
Přibyl, Zdeněk ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The thesis deals with the development of a balancing tool for the monitoring of selected waste streams, the related legislation, and the development of techno-economic models for waste treatment plants. In the research part of the thesis, the legislation setting the conditions of waste management is presented, the authorised packaging company EKO-KOM is introduced, including the remuneration calculator created. The practical part of the thesis describes the developed sub-tools and the balancing tool itself, which is the focus of the thesis. Subsequently, the waste stream is analysed and the waste treatment at the reference site is evaluated. Based on the processed data, the practical part leads to the development of techno-economic designs for the plastics processing plant and the energy transition.

PET waste treatment in the Czech waste management
Hanáček, Ondřej ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
The subject of this thesis is a description of PET waste collection and management systems within the Czech waste management. The essential part of this thesis is a description of the considered deposit-refund system for PET beverage bottles. It includes a comparison of these systems together with an analysis of the impacts that the possible introduction of a deposit-refund system would have on municipalities, waste processors, retailers, and producers. The economic requirements for the operation of both systems are compared on a specific region of the Czech Republic, for this purpose an approach to the assessment of operational requirements was designed and a calculation tool in MS Excel was compiled.

Municipal waste management in the context of the new Czech Waste Act
Kudela, Petr ; Pluskal, Jaroslav (referee) ; Kropáč, Jiří (advisor)
The subject of the thesis is the analysis of mass flows in municipal waste management in the Czech Republic and the preceding research of legislative documents related to the area of waste management with an emphasis on monitoring the legislative development of currently valid legislative documents in the legal area of the Czech Republic. As part of the description of the current state of waste treatment, a list of waste treatment facilities in operation was drawn up. Statistical data on waste production by municipalities in the Czech Republic and an estimate of the change in the financial requirements for waste collection and collection in connection with the legislative pressure to increase the share of separately separated components in municipal waste were prepared.

System for Plastics Packaging Waste Production Analysis
Bejdák, Jan ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
One of the very current topics today is the implementation of the principles of sustainable development and the circular economy. The Czech Republic has adopted legislative changes in this area and has committed itself to meeting the set targets for the utilization of municipal waste. This work deals with the development of a software tool for monitoring the production and structure of packaging waste in households. The principle of the tool lies in a database and a web application for user access to stored data. The main part of the work is a draft of the assignment for programming works on the tool. The draft consists in determining the logical context of the data used to describe the packages in the database, in specifying the functions of the web application and in creating a template for the user interface. The assignment was created iteratively based on testing of available tools. The current state of implementation of the draft is described.

Types of packaging and their representation in municipal waste
Kostková, Kateřina ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
The bachelor thesis deals with the types of packaging materials, related legislation and the use of packaging in practice. The research part of the work presents individual types of materials and their characteristics. An important part of waste treatment is the recycling and utilization of packaging waste. The work presents different recycling principles for individual materials. The practical part analyzes the individual representation of packaging materials of selected consumer products.

The ocean cleaning technology concepts
Jedličková, Kateřina ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The main aim of this master's thesis is the world ocean pollution by plastic waste. The introductory part of the thesis contains general information about the production of plastics and plastic waste, followed by data on ocean pollution by plastic waste including the estimated amount, pollution sources, and composition. Part of the thesis consists of the introduction of known concepts that are already actively looking for a solution to marine waste and of their mutual comparison. The following part deals with the plastic waste management, the possibilities of its treatment and utilization. The last area is the draft of an alternative system that is focused on an effective solution in accordance with environmental aspects. Within this draft, a material and economic balance is made.

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.

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.

Secondary raw materials production from municipal waste
Kouřil, Čeněk ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
The main purpose of the bachelor thesis is to give an overview of the current system of municipal waste management and to demonstrate its techno-economical demands. To solve these objectives, an analysis of the current state in Czech Republic was carried out and a calculation tool was created to evaluate the overall techno-economical balance of the management system at the regional level. The results of the tool showed that it is expensive for municipalities to carry out waste management activities and would not be feasible without complex subsidies. The reader gets a basic overview of the current waste management system in Czech Republic and acquires knowledge of its partial techno-economical costs.

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.
