Transport infrastructure in the perspective of circular economy
KŘIKLÁN, Radek
The main goal of this bachelor's thesis is to propose and recommend a solution for the implementation of transport infrastructure in the perspective of a circular economy. The proposed recommendations take into account the principles of the circular economy and try to improve the current situation. The theoretical part of the work deals with the theory of transport and transport infrastructure. We focus on the definition of the term traffic, as defined by different authors and how it can be viewed. What follows is the issue of the circular economy, which is intended to help the reader understand the basic principles of its operation. In the practical part, examples of successful circular economies and barriers preventing the transition from a linear to a circular economy are presented. The performed analysis of the management of construction and demolition waste is the basis for the proposal and recommendation.

Deposit refund system as a key tool for circular economy
Patka, Vojtěch ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
This bachelor´s thesis deals with the issue of PET packaging, more precisely PET beverage bottles, and with a possible solution to this issue using Deposit Refund System, reffered to as „DRS“. When comparing the current situation of PET beverage bottle management with the set targets and legislation of the EU and the Czech Republic, it can be concluded that it is necessary to adjust the approach to this part of waste management. The modern approach is the approach of so called circular economy, which considers waste as a potential source of material for re-production. DRS is a tool of circular economy which indicates high collection rate of PET beverage bottles in EU, i.e. the proportion of bottles returned and bottles placed on the market. However, DRS is only part of the overall PET beverage bottle management system which requires an efficient processing chain to function properly. The chain is described in detail from returning the used bottle to the production of a new one. A significant benefit in this chapter is the information obtained in interviews with experts from practice and during visits to production lines for PET preforms and PET bottles. The thesis is concluded with a SWOT analysis of DRS in the Czech Republic where the deposit system is likely to be introduced at the beginning of 2026 and its introduction is currently being widely discussed.

The Sustainable City: The Žižka Barracks in České Budějovice
Petečuk, Ondřej ; Zemen, Luboš (referee) ; Kratochvíl, Jan (advisor)
The subject of the diploma thesis is the proposal for the transformation of the former Žižkov barracks complex in České Budějovice. The area is located near the historical core. Currently, the complex is inaccessible to the public, and almost all buildings are vacant. The ensemble of buildings is not a cultural monument. The architectural-urbanistic study proposes a multifunctional urban development in the area. The theories of Aldo Rossi, Jan Gehl, and David Sim are applied in the urban design. The aim was to create conditions for construction that support the circular economy of building structures. The concept of these principles is demonstrated in the design of a community center building. Economic, social, and ecological values of the project are compared in the conclusion.

Mapping electromobility in the aspect of the circular economy
KOHOUTOVÁ, Nikola
This diploma thesis focuses on the mapping of electromobility and its potential in the context of the circular economy in the South Bohemian Region. Electromobility is a very researched topic and in connection with the circular economy brings new possibilities for more sustainable transport. The work focuses on transportation and analyzes traffic and the current state of goods transportation on roads and railways. This is the mapping of light trucks up to 3.5 t, which, when replaced by electric cars, are offered as a perspective solution for achieving the emission reduction goals mentioned in the European Green Deal. The work is based on the analysis of data from the transport yearbooks of the Ministry of Transport of Czech Republic and data from The Road and Motorway Directorate and the Transport Research Centre. The methodology includes the monitoring of parameters of transport performance, traffic intensity and transport of goods, subsequently analyzed using calculations of year-on-year changes. Based on these data, the future values of the parameters of traffic intensity, transportation of goods and transportation performance were calculated with the help of Holt's model, as well as estimates of the future need for electricity. Three variants of replacing a part of conventional trucks with electric ones were proposed, with the aim of reducing CO2 emissions, and in all of them the reduction was achieved thanks to electric cars. All predictions are based on real time series data from 2000 to 2022 and show the potential of electromobility in achieving the goals of the circular economy in transport. The results contribute to the discussion about the implementation of electromobility and its benefit or, conversely, disadvantage for the sustainability of transport.

Social Impacts in Transport in the Aspect of the Circular Economy
KNÍŽETOVÁ, Alexandra
The aim of the work was to evaluate selected social impacts of transport in the aspect of the circular economy based on the performed analysis. Selected impacts include GDP, emissions and energy consumption in road freight transport. The fourth variable of the analysis is the transport performance of this transport. The research question focuses on the long-term links between the monitored variables, grouped into pairs. The chosen methodological procedure assesses the presence of a cointegrating relationship as a long-term link between variables. The strongest links were recorded between energy consumption and transport performance, and between emissions and transport performance. This results in a proposal to improve the situation, which is based on the principles of the circular economy, specifically on the preference for combined transport with lower energy and emission demands.

Waste as a source of business opportunities for circular economy and bioeconomy
MAROUŠKOVÁ, Anna
This dissertation thesis underlines the promising potential of biowaste processing using Black Soldier Fly (BSF) larvae with the subsequent production of value-added products such as feed components, fertilizers, cosmetics, etc. The concept is gaining global popularity, although legislative challenges initially hindered EU companies, resulting in delays in the placement of BSF products on the market. Nevertheless, EU enterprises, leveraging the time afforded by evolving legislation, emerged with cutting-edge technologies, positioning them to produce high-quality protein for animal feed and other value-added products. The study reveals a significant correlation between business development and scientific achievements in the field of BSF rearing in the EU and EFTA Member states. Another finding of this study was that countries with established Bioeconomy strategies at the national level show higher numbers of publications and established companies in the field of BSF rearing compared to those with Bioeconomy strategies under development or other bioeconomy-related policies. However, the biggest finding of this study is the results of the BSF meal, soybean meal and fish meal competitiveness analysis for the first time conducted in the Czech Republic. The comprehensive analysis showed that BSF meal has the potential to compete with products like soybean meal and fish meal despite its current market price is still a major drawback. The main benefits of the BSF meal are well-balanced nutritional properties and demonstrated positive ecological impact. It was also discovered that under the current conditions, the key bottlenecks are insufficient BSF products supply and the overly strict EU legislation which causes challenges in the price competitiveness. However, based on the review accompanied by the competitiveness analysis results and taking into account political trends, it can be concluded that industrial insect rearing represents a significant commercial potential.

Risk Assessment of Textile Waste Management
Šindlerová, Vanesa ; Vymazal, Tomáš (referee) ; Hrabová, Kristýna (advisor)
This thesis deals with environmental risks arising from textile waste management. The introduction describes the context of textile problematics and maps the current situation of textile waste management. The main goal of this thesis is to determinate the environmental risks of low percentage of recycling. Recycling is one way of dealing with textile that mitigates the impact on the environment. For the evaluation of the causes and consequences of the researched problem are used Bow-tie analysis and Ishikawa’s diagram. The results of the work bring environmental risks resulting from the application of those selected methods. Part of the thesis is a questionnaire that evaluates the individual’s attitude to textiles. Results of the questionnaire reveals that not needed textiles are perceived as risk to the environment. At the same time, consumer behavior does not correspond with efforts to mitigate the identified impacts.
