Assessment of natural and recycled materials in buildings
Stránská, Zuzana ; Ostrý, Milan (referee) ; Lupíšek,, Antonín (referee) ; Sedlák, Jiří (advisor)
Life-Cycle Assessment (LCA) is an analytic method for evaluation of environmental impacts of products, services and technologies. It is associated with all the stages of a product's life. The environmental impacts are evaluated on the basis of material and energetic flows, which are in influence with the environment. These impacts are always determined in the relation with the function of the product or the service and so it is possible to compare them with the other alternatives. One of the most important reasons why I have chosen this dissertation thesis subject was the growing public interest in impacts of the building constructions on the environment and human organism. Only a few experts and scientific research centres deal with the problem of environmental impacts of the buildings in the Czech Republic so the main goal of this thesis is to help with a spreading a knowledge about it. There are four main problems to solve in the thesis: determination of environmental impacts of selected materials which are missing in available databases, creation of life cycle models of evaluated buildings, determining the most appropriate functional unit and determining the contents of the recommended LCA protocol for building analysis. In the first phase of the thesis there was built a detailed life cycle model of the reference building on the basis of available documents and databases. This "cradle to cradle" LCA model was then optimized for a large number of life cycle scenarios to determine the significance of the impact of individual variables on the overall environmental impact of the building. The knowledge gained from this analysis was applied to the lifecycle models of other buildings and then there was assembled the recommended form of the LCA protocol. In the final stage, the results of the environmental impacts were quantified on the different functional units which were used for determining the appropriate form.

WtE plant carbon footprint
Staňková, Lucie ; Brummer, Vladimír (referee) ; Krišpín, Jan (advisor)
The value of the carbon footprint of the WtE plant is necessary for reducing emitted greenhouse gases. In this paper, research on carbon footprint assessment is conducted, while the principles for calculating the carbon footprint according to EN 15978 standard for the sustainability of construction works through the whole life cycle are applied. This methodology is enriched with the technological unit's carbon footprint, including processes The proposed computational model is applied to determine the carbon footprint of the WtE plant Evecont. The main contribution to the carbon footprint of the WtE plant is the use phase due to carbon dioxide in the flue gas. A substantial carbon footprint reduction can be achieved by incorporating technology to capture carbon dioxide from the flue gas (CCS technology). The results achieved for the WtE plant are compared against landfill and heat from the central heat supply system. This work provides a tool that can be applied to other process industry units, allowing the carbon footprint to be calculated in detail and benchmarks to be established for the comparison of new projects.

Life Cycle Assessment (LCA) of Mixed Municipal Waste Collected in Frýdek-Místek
Hamšíková, Renata ; Remtová, Květa (advisor) ; Hadrabová, Alena (referee)
Diploma graduation thesis deals with analytical tool called Life Cycle Assessment (LCA). Paper explains this analytic tool and focuses on its possible application in municipal decision-making process. Thesis carries out specific application of Life Cycle Assessment (LCA) targeted towards disposal of mixed municipal waste collected from Frýdek-Místek city. Municipal waste management issues are mentioned in relation with Frýdek-Místek and year 2007. The aim is to analyze nowadays landfilling of mixed municipal waste done in Frýdek-Místek and to examine the possibility of incineration of mixed municipal waste in order to reach minimal total environmental impacts. The paper offers improvement suggestions based on extensive LCA study.
