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.

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.

The use of asphalt recycled materials in the base and subbase layers of pavements
Tanečková, Pavlína ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This thesis consists of theoretical and practical parts. The theoretical part gathers available information on the current state of construction and demolition waste management. This part discusses foreign experiences with SDW management, provides basic information on the introduction of circular economy. Equally important is the environmental impact, which is discussed from the perspective of Decree No 283/2023 Coll. It also provides basic information on construction and demolition waste and describes the recycling process. It also discusses the most common types of recyclates and their use in roads. The practical part of this thesis verifies the possibilities of using asphalt recyclates and their mixtures cemented with asphalt emulsion or hydraulic binder. The main objective was to verify the possibilities of using these recyclates in cemented subbase layers for urban roads. These possibilities were verified and then compared by means of laboratory tests. Finally, a comparison of cemented mixtures of asphalt recyclates with specific binder dosage and low temperature heating of the mixture for optimum compaction to the desired strength values using recyclates is made.

Návrh nábytkového prvku s využitím materiálu vyrobeného z morskej trávy
Bellayová, Veronika
The bachelor thesis focuses on exploring the possibilities of using the material from seagrass Posidonia Oceanica for production of furniture. The aim was to design a furniture element made of this material that would meet the criteria for sustainable products to the maximum extent possible. For a better understanding of the concept of eco-design, a literature review on the subject was developed, summarising its practices, tools, and strategies. For the production and exploration of seagrass materials, it was also important to develop a literature review on the topic of bio composite materials, seagrass materials and an overview of their use in furniture design.Two types of adhesives were used in the production of the material and the resulting material was tested for bending characteristics, Brinell hardness and tensile strength perpendicular to the plane of the board. The properties of the fabricated material were compared with particleboard. In the process of designing a furniture element from the tested material, review on seagrass side tables was carried out. Subsequently, a custom design was created with construction solution and visualizations. Finally, a FEM analysis was created for the designed element to verify its stability.
