Scissors for metal waste
Zborník, Radek ; Komenda, Lukáš (referee) ; Brandejs, Jan (advisor)
This thesis is focused on the innovation of already made hydraulic shears which are primarily used for cutting metal waste to a prescribed size. The aim is therefore to solve the problem of the bending of the shearing arm, the optimization of the number of cycles and thus increasing the efficiency of the shears. Part of the thesis will be also dedicated to energy savings. The secondary purpose is to familiarise the reader with the material cutting process using the shears – equipment used for cutting scrap metal, partial production of metal alloys, and to highlight the importance of metal recycling. The thesis includes a drawing of the assembly of the hydraulic shears.

CONSTRUCTION DETAILS FROM SECONDARY RAW MATERIALS USED FOR BUILDING ENVELOPE
Smolka, Radim ; Rybárik,, Ján (referee) ; Schmid, Pavel (referee) ; Šinogl,, Jiří (referee) ; Matějka, Libor (advisor)
One of the important reasons for the choice of the thesis topic are increasing requirements from the persons interested in low-energy, passive or even houses with almost zero energy consumption. During decreasing of the energy demand is within the framework of the idea of sustainable construction not only required to decrease the total energy demand of the buildings, search and solve the critical spots in the building jacketing, but also to use the secondary raw materials as full-value substitutions for commonly used products from the primary raw materials. The thesis tries to contribute to the possible usage of polymeric wastes in building industry. In an early stage of the thesis the main and partial targets together with the consecutive steps leading to their fulfilment were set. Selection of the suitable secondary raw materials, discussion with the specialists, initial sample mixing, finding their thermally – technical characteristics, press mould and fire kiln acquisition was carried out during the stage. The next phase is focused on the application of the products made from the secondary raw materials to the building envelope. The products are moulded according to the thermally – technical properties. Performed moulding approved that the products are fully functional and after reaching the required value of heat conductivity coefficient products eliminate imperfections of the solutions used at present. Strapping product for the threshold door joint is registered at Industrial Property Office of the Czech Republic and at European Patent Office at the same time. Recycled materials put into production represent possibilities how to decrease number of acquired virgin materials, need of primary energy and how to decrease risks connected to the waste disposal. Society is starting positively approaching to the products that are partially or fully produced from the secondary raw materials. Nevertheless, before the products from the recycled materials enter the peop

Evaluation of industrial heritage
Navrátil, Oldřich ; Králová, Eva (referee) ; Zemánek, Václav (referee) ; Ryšková, Michaela (referee) ; Zemánková, Helena (advisor)
The main subject is evaluation of effective use in terms of care (not only within protection of monuments) in order to save and protect industrial heritage. Pointing out on critical issues connected with the end of production of traditional branches which played the key role in historical development of our cities. Nowadays abandoned buildings and sites are represented by memory of the place or its prosperity. New owners often don't share the positive approach to the industrial heritage, developers are seeking new sites, cities and inhabitants have developed new needs through the time. The work will demonstrate examples within European context and will make recommendations in monitoring and classification of industrial heritage to prevent undo able losses.

Monument
Mrva, Jozef ; Vaněk, Vojtěch (referee) ; Stratil, Václav (advisor)
I base my spatial installations upon working with waste materials. I use characteristic and aesthetics of cardboard and wooden clippings to express dialogue with geometrical drawings, which I have been producing since the last year. Protracted and unexpectedly-carved shapes resemble timber beams or ruins and can lead to ecological or eschatological questions. The title "Monument" is an ironical disputation with human trace and materials we use without giving them any further attention.

Recycling-Aware Building Design
Dobrovolný, Petr
The paper focuses on recycling in the building industry, placing emphasis on load-bearing building structures. Current practice is taken as the starting point, namely the processes of demolition, material separation and further processing. Based on collected data, the paper determines the key principles for good building design that takes into account future recycling.

Design of Sorting Waste Containers System
Vostrikova, Daria ; Zdařil, Zdeněk (referee) ; Sládek, Josef (advisor)
Separated waste collection is one step in the recycling process. For this purpose, containers for recycling are used. This thesis investigates the new concept of containers design towards creating an original and compact solution for cities. The final solution is a set of containers where the key idea is based on the principle of building blocks. Another innovative feature of the design solution is the possibility to choose opening configurations. It provides variability along with adapting to surrounding area. The result is a design concept hat has effectively fulfilled functional, technological, ergonomic and aesthetic needs.

Quality control of biodegradable waste process
Krbalová, Maria ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The waste production and especially biodegradable waste is following mankind since the beginning of his existence. This thesis deals with a description and dividing of current available waste process technologies, including description of their advantages and disadvantages. The work is also focused on the more detailed description of the composting technology, its control and opportunities to influence on resulting parameters of compost product. The information about technical description of workplace equipments, including industrial and technological processes was provided by the company VIA ALTA from their compost plant in Blansko.

Utilization of Waste Vegetable Oils as an Alternative Fuel for Diesel Combustion Engines
Michna, Lukáš ; Novotný, Pavel (referee) ; Stodola, Jiří (advisor)
In the introduction this thesis brings a short summary of the energy, environmental and economical balance, related to the production and use of conventional fuels for diesel engines, and compares them with possibility of using recycled cooking vegetable oils as a fuel. The main part focuses on the laboratory analysis of major physical and chemical properties of this alternative fuel and on their comparison to diesel fuel, especially according to ČSN EN 590 norm. In conclusion there is a proposal of diesel vehicle modification to be propelled with waste vegetable oils.

Recovery of Energy from Municipal Wastes
Procházka, Jaroslav ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
Master’s thesis deal with the design of waste to energy plant of municipal waste. The design of technology is to build the component parts of plant and basic calculation of individual apparatus. Overall technology concists of pretreatment of municipal waste, which is then stored in the bunker. Pretreatment municipal waste is fed into the counterflow rotary kiln. Flue Gates from the kilns are routed through multicyklony in the heat recovery steam generators (HRSG). The multicyklon separates the pollutants. The HRSG generates steam required properties from the feedwater from the heat kontent of gas. Superheated steam is driven to the condensing turbine with extract steam for distrikt rating and for power generation. The flue gas from the HRSG are passed through purification section, in which are separand pollutants the dry method purification. The left heat content of flue gas is used in heat exchanger with twist tube for preheating feed water for the HRSG. The flue gas are fed to the stack.
