Green Roofs Using Hydrophilic Mineral Wool
Vacek, Petr ; Moudrý, Ivan (referee) ; Šrámek,, František (referee) ; Matějka, Libor (advisor)
The thesis deals with the use of hydrophilic mineral wool in green roof structures. In the first part of the thesis, based on current legislation, there are summarized relevant technical properties of the hydrophilic wool. Specific demands on the green roof parts were classified and the work was consequently updated by the research of available products from the national market. A large part of the thesis consists of the extended documentation of technical properties of new products and also the changes that are associated with ageing after the material incorporation into the structure. Not only the laboratory properties of the material itself, but also properties of the material embedded in green roof structure were measured, for example an acoustic capabilities. Water accumulation properties of the mineral wool were documented on the real roof models too. Various impacts were observed by using mineral wool in comparison with substrate assemblies. Additional experiments were applied on using different types of mineral wool for an assessment of specific green roof vegetation adaptation. The environmental product declarations for each mineral wool product were calculated with the specific software using LCA methodology. In this way, the environmental impacts of mineral wool could be compared with other materials, such as artificial substrates, foils, etc. As a conclusion of the research results were summarized and reported demands for the hydrophilic mineral wool use in the green roof structures.

Ecology of wooden buildings and passive wooden buildings
Servusová, Michaela ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
This thesis deals with an ecological impact of a building process. The work is focused on the impact of wooden buildings on environment. In theoretical part of the thesis concepts related to the construction of wooden buildings and passive houses are described and possible environmental assessment methods are defined. In the practical part of the thesis environmental aspects of construction production and materials are evaluated. Prices of natural materials are also defined and the most suitable ecological solution is selected.

Environmental Impact Assessment of Manufacturing Abrasion Resistant Coatings with Magnetron Sputtering
Krobauer, Jakub ; Holub, Martin (referee) ; Kocmanová, Alena (advisor)
This thesis is focused on the environmental impact assesment of the manufacturing process of cutting tool coatings. Described are current environmental problems and duties of companies affecting the environment. There is a description of methods used in environmental management, one of which is the LCA method. This method is then used to compare environmental impacts of TiN and AlTiN coatings. The thesis describes manufacturing process of these coatings and evaluates environmental impacts for both coatings. These results are then compared and conclusions and recommendations are made.

Material Flows and Environmental Impacts of s-WEEE in the Czech Republic
Polák, Miloš ; Hák, Tomáš (advisor) ; Kočí, Vladimír (referee) ; Vladík, Jaroslav (referee)
This thesis is a comprehensive study describing and quantifying material flows of waste electric and electronic equipment (WEEE) in the Czech Republic; specifically the material flow of small waste electric and electronic equipment (s-WEEE) as well as representative substances. The studied material flows were estimated regarding aspects of the environmental impact. The End-of-Life mobile phone is seen as a typical representative of s-WEEE ; therefore material flows of mobile phones are described in this thesis as well. To put it in concrete figures, approximately 124 thousand tons of WEEE from households originated in the Czech Republic in 2010, where each inhabitant got rid off 4 pieces of WEEE in average. Further, total production calculating also consumer-like WEEE from companies and institutions was around 141 thousand tons in 2010. S-WEEE present around 15% from the total amount of WEEE originating in 2010; however it is more than 80% as regards the number of pieces. Despite of that fact the recycling potential of Au for instance is slightly higher by s-WEEE than by large WEEE (63kg/year compared to the 59kg/year respectively). As regards estimation of the total production of EoL mobile phones, around 45 thousand pieces originated in the Czech Republic between the years 1990-2000 and 6,5...
