Cirkulární ekonomika podniku ve vztahu k jeho finanční situaci
Šátková, Petra
Natural resources are limited, and their consumption is increasing as the Earth's population grows. Today's economic system is linear, operating on the principle of 'take-make-dispose'. The transition to a circular economy, characterized by the 'take – make – recycle' principle, uses resources efficiently and reduces waste and pollution. However, implementing the circular economy requires significant initial investments. Therefore, if a company is planning to introduce elements of the circular economy into the business, it can be very beneficial to break down the company's financial situation. Financial analysis is an important tool to reach this aim. The thesis is divided into two parts. The first part is devoted to the circular economy, its differences from the linear economy and the MCI indicator, which can be used to measure the level of circularity of waste at a product or the whole company. In the practical part, the linear flow index of the most produced product in the firm is calculated based on the procedure described in the theoretical part. The second part of the thesis is devoted to financial analysis and its detailed theoretical description based on academic literature. In the practical part the financial analysis of BASEKO, spol. s.r.o. is calculated based on data retrieved from the financial statements in the period 2016-2020. From the financial analysis it was found that BASEKO is a financially stable enterprise on the market, which is not threatened by financial problems in the near future. The circular economy of the enterprise cannot be calculated due to the large variability of products. The index of linear flow of the product is 37%, which the author considers a very positive result. Finally, some recommendations are set out that could contribute to the prosperity of the company both financially and in terms of promoting the circular economy in the company.

Population mobility in the circular economy
TESAŘOVÁ, Marie
The aim of the thesis is to evaluate the state of mobility of the population in everyday commuting to work and school at the level of regions of the Czech Republic in the aspect of circular economy. Secondary data mainly from the yearbooks of the Ministry of Transport and Tourism, the Czech Statistical Office, the Czech Hydrometeorological Institute, etc. were used for the research. The professional assumption of circular economy in the transport issue was drawn from the documents of the European Union and the Ministry of Environment of the Czech Republic. It is on the basis of the EU documents that an "ideal region" that meets the EU requirements for circularity in transport was drawn up for the purposes of the analysis. From the above sources, the data was analysed using statistical methods and a "mobility circularity degree indicator" was compiled for the purpose of this thesis. The indicator describes and evaluates the level of mobility in each region of the Czech Republic and its result is evaluated. Finally, the findings are followed by proposals for measures to maintain or improve the state of mobility in the regions.

Persistent water pollutants: case of ethylenediaminetetraacetic acid in the Czech Republic
Prášek, Jan ; Šauer, Petr ; Keprtová, Karolína
Reuse and recycling of products composed of natural matter is relatively without significant environmental problems. However, recycling of products produced using modern synthetic technologies often brings new challenges. Our analysis has shown that substitution of citric acid with artificial substance of ethylenediaminetetraacetic acid causes important environmental problems. The case study carried out in the Elbe river basin shows that the ethylenediaminetetraacetic acid concentration standard has been exceeded, particularly from confluence of the Vltava and Elbe rivers. Open questions and tasks for future technological development and environmental policies are formulated, particularly the idea to replace artificial substances with nature-based ones. This would enable better introduction of circular economy ideas in the use of resources.

Waste composition analysis as a support mechanism for circular economics
Halamíček, Samuel ; Varbanov, Petar Sabev (referee) ; Fan, Yee Van (advisor)
Předkládaná diplomová práce se zaměřuje na využití analýzy složení odpadu k usnadnění přechodu lineárního odpadového hospodářství na oběhové hospodářství. První část práce se zabývá úvodem do tématu odpadového a oběhového hospodářství, po kterém následuje seznámení s technikami a nástroji pro provádění analýzy složení odpadu. Druhá část práce představuje detailní analýzu, která identifikuje složení odpadu na první a třetí úrovni se zaměřením na komunální odpad. Složení odpadu vychází z certifikované metodiky, která vznikla v rámci projektu TIRSMZP719. Správa a analýza dat byla prováděna především za pomocí programovacího jazyka Visual Basic for Application (VBA). Výsledky analýzy složení odpadů jsou znázorněny pomocí grafů, které umožňují identifikovat možné trendy a rozdíly v toku odpadů v rámci zkoumaného období, území či jiného parametru. Použitelnost nástroje při navrhování vhodných způsobů úpravy a využití odpadů na základě zjištěného složení je prezentováno na případové studii města Brna. Z analýzy vyplývá, že největší podíl (23,17 %) směsného komunálního odpadu tvoří bioodpad, přičemž jako hlavní složka bioodpadu byla identifikována složka potravinových odpadů. Toto zjištění navrhuje vysokou proveditelnost a potenciál pro výrobu bioplynu. V této práci je rovněž navrženo řešení zpracování odpadu i pro ostatní složky směsného komunálního odpadu. Takové zhodnocení je klíčové a mohlo by vést k potenciálnímu snížení množství směsného komunálního odpadu až o 40 %. Toto zjištění je velmi důležité, protože celková navržená koncepce dokáže odpovědět právě na separační potenciál, který je navázán na stanovené cíle či jiné závazky související s cíli Plánu odpadového hospodářství ČR. Navržené posouzení akcentuje navržené cíle a ukazuje potenciál pro jejich splnění.

Kolátor, Matyáš ; Smejkalová, Veronika (referee) ; Pluskal, Jaroslav (advisor)
The thesis deals with the description, analysis and reconstruction of waste evidence. Nowadays, more and more emphasis is put on the issue of waste management and its efficient use. Legislation has set demanding targets for increased waste recovery and the development of a circular economy. In order to achieve these objectives, it is necessary to plan and organize the structure of waste management strategically. Important decisions in the field of waste management are based on data and the production and processing of waste. The quality of waste data has a major impact on the success of the process. The aim of this thesis is to describe the system of record, but also the possibilities of improving and reconstructing invalid data. The core of the work is the testing and improvement of a data reconciliation tool REVEDATO developed at the Institute of Process Engineering. The computational tool is based on the mathematical apparatus of data balancing, for which the correct definition of the weights is crucial, which will be the main subject of the work.
