The Effect of Socio-Demographic Factors on Consumer Trends in the Czech Republic
Čechová, Tereza ; Šťastná, Lenka (advisor) ; Kolář, Daniel (referee)
The thesis examines the potential effects of various socio-demographic determinants on consumer trends in the Czech market over the years 2009- 2019. We use data from the agency Median, s.r.o., which has been researching consumer behavior since 1993. This work analyzes dependent categorical variables that define potential consumer trends and represent answers of respondents or households. We utilized an ordinal logistic regression for the analysis, which we subsequently tested by Brant's test. Statistically significant results from the models are similar to the results in previous studies. Specifically, during the years 2009-2019, the interest in recycling increases, people tend to buy organic food more often, and spending on Czech products decreases slightly (especially in 2018 and 2019), and people tend to spend more money on vacation. For example, the bachelor thesis shows that women have a greater tendency to buy organic products and Czech food than men and, at the same time, recycle more often than men. Furthermore, new variables are examined in regards to observed trends. Such variables are the number of persons employed in the household and the ABCDE classification. Overall, the main contributions of this thesis are Czech consumer preferences and trends over eleven years and detailed...
Circular economy in the Czech surroundings - experience of companies and the view of experts
Leová, Leona ; Rynda, Ivan (advisor) ; Milerová Prášková, Dagmar (referee)
The diploma thesis deals with the concept of circular economy (hereinafter CE) and its application in several Czech and one multinational company. On these specific examples of companies, the work shows how circularity is achieved, with all the essentials of this fact, what support for the concept is offered in the Czech Republic and, last but not least, what obstacles and problems the companies face. Along with this practical experience, opinions by theoretical experts who deal with the issue in their profession are further examined. The aim of the work was to map the matter of use of secondary raw materials and other principles of CE in both practical and theoretical spheres of knowledge, and where possible, to compare these two views. Furthermore, the work focuses on the benefits of real use of the principles of CE in the Czech conditions from an environmental point of view. In its theoretical part, it first addresses the issue of waste in general, especially from the perspective of a global problem. It presents the development, current situation and forecast of the size of waste generation, including its impacts. Furthermore, it has introduced the concept of CE, its various concepts and definitions, together with the main principles. Subsequently, it presents the real adoption of the concept by...
Biodegradable Waste: School Project for Lower Secondary School
Dvořáková, Kateřina ; Pavlasová, Lenka (advisor) ; Skýbová, Jana (referee)
The proper way to manage biological waste has only recently become a topic of discussion and the public still does not have enough information about it and does not have a comprehensive opinion. In order for bio-waste to be properly managed, knowledge of this topic and positive attitude towards it is necessary, in class this could be achieved by activating pupils through project based education. Teaching in projects is a great way to understand the issue, which can influence pupils' attitudes towards bio-waste management. The aim of this diploma thesis is to create a project on the topic of biodegradable waste, and then to find out how the knowledge and opinions of students about bio-waste have changed. The created project was verified at the lower secondary school, for which it is primarily intended. A total of 54 6th-year pupils was involved in this project. They were given a pretest before the start of the project, finding out the initial knowledge about bio-waste and their opinion on the classification of bio-waste. After the project, the pupils completed a posttest and by comparing the individual answers, it was determined whether and how the knowledge of the tested pupils and their attitude towards the topic changed. The answers of individual pupils in the pretest and posttest were evaluated...

The online platform, created as the output of the thesis, provides sources for possible conscious approaches to design. It consists of a database of innovative materials, research texts, related links and interviews with designers, material specialists, scientists and technologists. The website can serve as a starting point for students and designers who are interested in current possibilities and new ways leading to design that is responsible to nature and humans.
Financing of Business activities
Ziková, Anna ; Havíř, David (referee) ; Heralecký, Tomáš (advisor)

The theoretical part includes the basic terms such as an entrepreneur, business plan and the sources of finance. The practical part consists of analysis of current state, which focuses on SWOT, SLEPTE and Porter analysis, and suggestion which focuses on business plan and the possibilities of source of finance.
Environmental Protection Legislation and The Possibility of Using Waste as a Secondary Raw Material With a Focus on the Recycling of PET Bottles
Hejl, Martin ; Pavláková Dočekalová, Marie (referee) ; Kocmanová, Alena (advisor)
The aim of this bachelor's thesis is to analyze the recycling of plastics and the analysis of the recycling process of PET bottles in the company PETKA CZ, a.s. In the last analysis of the work influencing the ways to obtain input material for the production of recycling from PET bottles, management of plastic waste, proposals for improving the production of this company and at the same time the possibilities of reducing waste in the production of recycling. Furthermore, this work describes the legislative regulation of environmental protection, general principles of recycling, how to recycle the company PETKA CZ, a.s. It currently determines and at the same time how we could recycle this to use in the future.
Negative impacts of renewable resources on environment
Kopeček, Marek ; Chýlek, Radomír (referee) ; Sitek, Tomáš (advisor)
Current society understands the need to protect the environment. Renewable energy resources are one of the major topics of environmental protection. Their benefits are reducing greenhouse gas emissions and reducing dependence on fossil fuels. The production process, operation, recycling, and possible accidents of renewable energy resources are investigated in each chapter. Attention was paid mainly to the most used renewable sources. Finally, the negative impacts are evaluated, and it is defined which renewable energy resources could be classified as ecological.
Use of recycled building materials to urban pavement constructions
Průdková, Hana ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This bachelor thesis describes the possibilities of construction and demolition waste management. It examines the issue of allocation and management of this waste and evaluates possibilities of their further use. It deals with production and use of recycled materials in construction of urban roads and economic advantage of recycled materials in comparison to natural aggregates. This work also discusses the issue of aerated concrete, as a modern building material, that will soon appear in construction and demolition waste to a greater extent. The practical part examines properties of mixed recyclates with a certain amount of brick and aerated concrete particles by testing the bulk density of grains and water absorption, freezing and thawing resistance and crushing resistance.

Pijáčková, Erika ; Křížová, Klára (referee) ; Hela, Rudolf (advisor)
The bachelor's thesis deals with the topic of recycled concrete aggregate and its use in the field of structural concrete. The aim of the work was to describe the possibility of complete or partial replacement of natural aggregates with recycled concrete aggregates for concretes of strength classes C16/20 to C30/37. The theoretical part is composed of findings from both domestic and foreign research and legislation, which were used to evaluate the possibility of more frequent use of recycled concrete aggregates in civil engineering in the Czech Republic. The experimental part consists of the design of concrete recipes with natural and concrete recycled aggregates and their economic evaluation.
