Analysis and optimization of the current state of waste management in rPET InWaste s.r.o.
Dočekal, Petr ; Vymazal, Petr (referee) ; Chorazy, Tomáš (advisor)
This master's thesis deals with the analysis of selected waste from production and the proposal of appropriate optimization of their management in accordance with the principles of circular economy and current legislation in force in the Czech Republic. It also deals with the optimization of waste management arising in the administrative premises of the company. The aim of the work was to prepare a research of current legislative and strategic documents in the field of waste management and, in connection with this, a subsequent proposal for optimization for selected waste streams. In the experimental part, analysis of selected waste streams from the production line was carried out using FTIR, titration and vacuum evaporation methods. The first part of the thesis consists of the research of legal regulations and strategic documents in the EU and Czech republic. In the second part, the optimization of selected waste management is proposed. For some of the proposed solutions, the thesis evaluates the economic viability of the proposed solution compared to conventional management methods. The results and the methods used led to the proposal of optimization of waste management in production and administrative part of the company rPET InWaste s.r.o.

Methods of energy treatment of municipal waste
Štork, Martin ; Köbölová, Klaudia (referee) ; Linda, Jakub (advisor)
The bachelor's thesis deals with the topic of how to deal with waste in order to obtain as much energy as possible from it. That's why we are dealing with restrictions on landfilling. In the theoretical part of the thesis, we will find the types of waste and their characteristics, as well as the ways in which waste can be worked. In the practical part of the thesis, I try to show how waste could be worked in the future, ideally for a large yield of energy and with minimal air pollution during waste processing. This results in a complete restriction of landfilling.

Optimization of Production Processes Using Lean Methodology
Jablonka, Ján ; MBA, Marek Chromý, (referee) ; Juřica, Pavel (advisor)
The aim of this thesis is the implementation of lean manufacturing principles according to the lean methodology in selected company to minimize waste and effectiveness of production. The theoretical part is focused on defining the terms lean manufacturing, waste and lean methods that serve as the foundation for the practical part. The practical part is divided into several parts. First step is to do a SWOT analysis of production in a particular company. Using the lean tools, we find the root cause of the problem and propose solutions to effectiveness the manufacturing process. Part of the proposals will also benefit the proposed solutions. It is necessary to note that according to the lean methodology, not every proposal must automatically have a financial impact.

The Use of Alternative Sources in the Building Industry
Dvořák, Jakub ; Vymazal, Tomáš (referee) ; Žižková, Nikol (advisor)
This bachelor thesis is focused on the use of waste as alternative raw materials in construction industry. The first part is dedicated to the historical development of waste management, to the valid legislation in the Czech Republic in 2017 and outlines the distribution of waste according to various criteria. The information about waste production and waste management is processed in the form of tables and graphs. The more extensive second part of the thesis uses theoretical knowledge in the field of waste management and on the base of the Waste Separation Catalog is composed a list of waste materials which can be used in construction industry. Further are described the possibilities of suitable waste utilization at production and also mentioned some particular construction products with their features.
