Water management in buildings
Kozub, Josef ; Raček, Jakub (referee) ; Biela, Renata (advisor)
This thesis deals with the use of gray water and rain. In this thesis is a comparison of utilization in the Czech Republic and abroad and the financial savings arising in the use of these waters. Composition and permitted limits for dealing with these waters, individual adjustment methods, particularly for the accumulation of rainwater and gray water. Each chapter lists the recommended values and examples for application of individual technologies and examples of the use of rainwater and gray water.

Possibilities of using recycled concrete as fine aggregate replacement in cement screeds
Nováková, Iveta ; Brožovský,, jiří (referee) ; Hubáček, Adam (advisor)
The bachelor thesis deals with summary of knowledge about cement-based screed with partial replacement of natural aggregates by recycled aggregates. Special emphasis is given to describing and studying characteristics of cement-based flowscreed. In this study are described feedstocks with requirements which they must meet and test methods for testing properties of screeds. One part is also given to practical application of cement-based flowscreed with partial replacement of natural aggregates by recycled aggregates.

Comparative Analysis of Selected Waste Management Systems in the United States
Brožová, Eva Antonie ; Osersová, Marta (advisor) ; Ropický, Jan (referee)
This thesis concerns a comparison of two currently the most frequently occuring recycling waste systems in the United States of America -- Single stream and Dual stream recycling systems and an assessment of feasible utilization of Single stream system in the Czech Republic. The comparison is performed from several aspects: investment costs, operating costs, costs of the processors of secondary raw materials, costs of environmental pollution caused by CO2, SO2 and NOx, capacity utilization and citizens participation in the system, focusing on a single commodity; paper and cardboard waste. As according to realized studies the systems represent different load for individual entities in the economy cost-benefit method is used for the comparison. Using this method, four collection areas and the most important beneficiaries (municipal entity, secondary raw materials processors, landfill and residents) involved in the system are analyzed in the state of Pennsylvania. None of the existing studies did not take into account costs and benefits of more than one entity so far. In the Czech Republic no such studies have been realized, therefore this issue has become the subject of this thesis. In term of costs and benefits for the municipal entity the results of realized studies coincide in results of this thesis, i.e. Dual stream recycling system is more suitable for small collection areas. However from the point of view of all the major beneficiaries results of this thesis vastly differ. Based on this analysis it can be concluded that any of the above mentioned systems is not suitable for small communities, regarding the fact the values for the Single stream system are less negative. Application of Single stream system in the Czech Republic, namely in Prague, with all its limitations (we assume costs derived from the U.S. market) comes more favorable than the currently implemented system.

Reverse Logistics in Food Supply Chains
VALTA, Tomáš
For better understanding of the meaning of reverse logistics it is necessary to analyse and describe its function in a real company. In this case, the company Kaufland ČR, v. o. s. is used to fulfil these tasks. The main objective of the presented thesis is to analyse the function of reverse logistics in the company and to compare the findings with theoretical knowledge; alternatively, to try to suggest some innovations in the company.

Recovery of Valuable Components from MSWI Bottom Ash
Šyc, Michal ; Kameníková, Petra ; Krausová, A. ; Baloch, T. ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Municipal solid waste incineration bottom ash contains wide range of valuable components, like ferrous and non-ferrous metals, rare earth elements, glass, ceramics and minerals for construction industry. The composition of bottom ash corresponds to incinerated waste composition and it is variable with respect to plant locality and season. The paper summarizes suitable methods for recovery of valuable components and presents the composition of bottom ash from ZEVO Malešice.

Management of municipal solid waste in the town Prachatice
MÁDL, Josef
The aim of the bachelor thesis is to assess the waste management policy in the town Prachatice and to analyze the waste management at the disposal site Libínské Sedlo. The thesis also includes information about how local population views this issue. A contingent valuation method and a structured interview were used as assessing methods here.With help of technical literature the theoretical part of the paper defines expressions related to the waste management and handling the waste. The analytical part assesses the waste management in the town Prachatice with help of information provided by Prachatice Municipality.

Sustainability Analysis of Small and Medium Enterprises
Vojtěšek, Cyril ; Basl, Josef (advisor) ; Gála, Libor (referee)
The Diploma thesis analyzes the attitude of small and medium Czech enterprises towards the Green IT and sustainability concept. Several practices such as consolidation and virtualization of servers, desktop virtualization, cloud computing, energy management, dematerialization and recycling are discussed with regards to their contribution to global sustainability. The common denominator of most of the Green IT practices is the energy consumption reduction. The increasing information technology's demand for energy is viewed as a major contributor to the global carbon footprint and Green IT practices are assessed in terms of how much energy can be saved by incorporating them in a company policy. Besides energy consumption material aspects are another significant part of Green IT. Both the toxicity of certain materials used in the manufacturing process and the increased need for proper recycling of electronic waste are discussed in respective chapters. Information technology does not only add to the global carbon footprint, but it can also provide means to reduce the emissions of other sectors. Companies can reduce their energy consumption by improving logistics (smart logistics) or buildings (smart buildings) efficiency. Teleworking is another practice which enables millions of people work outside their office and contributes to global sustainability. The analytical part presents a survey of Czech small and medium enterprises and their attitude to Green IT. The main objective of the survey is to find out how many companies have implemented Green IT into their company policy. Company representatives report on which Green IT practices they have adopted and why. Responses are analyzed and findings and conclusions are presented.
