Circular economy using analysis of separated municipal waste
Plánková, Tereza ; Kropáč, Jiří (referee) ; Nevrlý, Vlastimír (advisor)
The bachelor thesis analyses the current state of waste management and presents legislation and changes in waste treatment. The ban on landfilling of usable waste from 2024 and the set recycling targets are the main reasons for analysing the production of the separated components. The thesis deals with revealing potential for increasing the material, or energy, recovery of waste. As a key waste stream, biodegradable waste has been identified due to its rapidly growing production for the future. Modelling of production dependence for territorial units was performed using statistical methods in STATISTICA software based on socio-economic factors. The resulting model for production determination was obtained by multidimensional regression analysis. Applying the model to individual waste producers will allow efficient planning of support assets from an economic and infrastructure point of view.

Modeling the Impacts of Changes in Waste Management on Key Technologies
Jadrný, Josef ; Suzová, Jana (referee) ; Weidlich, Tomáš (referee) ; Pavlas, Martin (advisor)
The doctoral thesis focuses on waste management planning in the Czech Republic with regard to key technologies. The operation of processing facilities is influenced by strategic documents that reflect the legislative framework of the EU and the Czech Republic. Due to the introduction of new principles and evaluation criteria, it is necessary to regularly update the Waste Management Plan at the state and regional level, according to the Waste Act No. 541/2020 Coll. When creating new strategic documents, emphasis should be placed on the use of available computing tools, inter-regional cooperation and the specific formulation of goals and measures. The individual goals of waste management must be taken into account when operating existing facilities and also when planning the necessary infrastructure. The attention in this text is devoted to the analysis of the current state of waste management in the Liberec Region with a focus on key technologies. The mentioned approaches and recommendations can be further applied to any region of the Czech Republic.

Dočekal, Petr ; Vymazal, Petr (referee) ; Chorazy, Tomáš (advisor)
This bachelor thesis deals with the use of selected types of waste under the conditions of current legislation in force in the Czech Republic. It focuses on plastic packaging waste and sewage sludge – waste generated from municipal wastewater treatment. The aim of the work was to process a search of current legislation and strategic documents in the field of waste management in the context of the principles of circular economy and then design and then critical evaluation of the optimal system of utilization of the above waste based on the principles of circular economy. Both its strengths and weaknesses as well as basic economic parameters were described. The first part of the work is a description and current methods of waste management and search for legislation and strategic documents at the EU and Czech level. In the second part, the optimal circulatory method of waste management is designed and evaluated. A delivery system is currently in place for plastic packaging waste. The bachelor work deals with a new system of taking back PET bottles and compares their strengths and weaknesses. For the sewage sludge, drying and subsequent pyrolysis were chosen as the optimal treatment method, which seems to be a very efficient method.

Legal aspects of the circular economy
Kučerová, Zuzana ; Sobotka, Michal (advisor) ; Falteisková, Sabina (referee)
Legal aspects of the circular economy Abstract The diploma thesis deals with the issue of legal aspects of the circular economy. This concept is based on resource efficiency with the intention to minimize waste generation. This approach is considered to be the future of economies not only in the European Union, but also in the rest of the world. The thesis aims to provide a comprehensive overview of the circular economy and the legal background of this concept in the EU and the Czech Republic. Given that the legislation of the circular economy has so far been reflected at the EU and national level predominantly in the field of waste management, it forms a significant part of this thesis. The projection of the principles of the circular economy into the legal order as well as the future development of this concept is evaluated. Recognized advantages and disadvantages in the current circular economy legislation are formulated at the end of the thesis. Subsequently, the thesis sets recommendations for the future direction of the circular economy and for its efficiency enhancement.

Specifics of building design from recycled building materials
Dobrovolný, Petr ; Pifko, Henrich (referee) ; Innemanová,, Petra (referee) ; Žabičková, Ivana (advisor)
Nowadays, the developed societies increasingly adhere to the ideas of sustainability, which also include the issues of raw material intensity and waste management. EU countries declare their intention to move towards so-called circular economy, where production, consumption, waste management and the market of secondary raw materials function in predominantly closed cycles. Due to its high share of raw material consumption and the amount of waste generated, the construction industry is one of the priority sectors in which these changes should take place. Consequently, the interest in recycling of construction and demolition waste will probably grow. This thesis examines the chosen topic from the architect's point of view. The issue of recycling of building materials is dealt with in the context of contemporary construction industry. The introductory part describes main material flows: the most used building materials, the method of waste management and the possibilities of its further use. The relationships between the design of the building and the production of construction waste are defined. The issue of building with recycled building materials is handled in more detail. In the main part, the design of a model object made of recycled building materials is elaborated. The individual building structures are analyzed in terms of the suitability of the use of recycled building materials and waste management after the end of a lifecycle of the building and a comparison is made with alternative structures made of conventional building materials. At the end of the work, an evaluation of the usability of recycled building materials in building structures and their economic potential is performed. There is also an evaluation of the specifics of working with recycled building materials in the design of the building.
