Environmental aspect of optimal waste management design
Šťastná, Liliana ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
This bachelor thesis of research character is focused on a life cycle assessment method LCA (life cycle assessment), especially at impact assessment LCIA (life cycle impact assessment). At the beginning of this thesis, there is an introduction to LCA method and characterization of its stages with a closer focus on the LCIA and associated methodologies. The thesis characterizes basic categories of impact and also substances with immission limits that have an impact on the categories of impact. Then there is an evaluation of the quality of air in recent years and the emissions of the TERMIZO incinerator in Liberec.

ID Gallery
Slavík, Jiří ; Sochorová,, Zuzana (referee) ; Struhala, Karel (advisor)
The aim of the thesis is to design a two-storey gallery and café building in Chrudim. The thesis has three parts. The first part presents the architectural and structural designs for the building permit. The building consists of two parts: a two -storey gallery and a one-storey café with necessary facilities. There is a green roof above the gallery and a terrace above the café. The envelope wall is insulated with mineral wool and loadbearing structures are designed from reinforced concrete. Internal non-load-bearing structures are designed of aerated concrete and plasterboard. The floors are monolithic reinforced concrete. I evaluated the building for Energy Performance Certificate. The second part proposes the design of selected building services: HVAC, artificial lighting and rainwater management system. There are two mechanical ventilation unit with heat recovery, which partly provide heating and cooling. The remaining heat is provided by local district heating grid. The designs also include concept of a photovoltaic plant on the roof. Third part assesses the life cycle assessment (LCA) of the structures. All the proposed compositions have the same main function - to ensure the stability of the building, fire safety, weather protection and thermal comfort. Six similar compositions of the vertical wall structure are proposed, combining different types of load-bearing masonry with ETICS system, ventilated facade, variant of aerated concrete blocks or VELOX system formwork. For the selected compositions, the functional unit is 1 m2 with a service life of 50 years and a heat transfer coefficient of U=0.216 ± 0.002 W/m2.K.

Environmental Impact Assessment for Powder Coating Technology
Havlíček, Lukáš ; Mukhametzianova, Leisan (referee) ; Krbalová, Maria (advisor)
This diploma thesis is focused on evaluating an environmental impact of using LCA methodology. LCA is a methodology of powder varnishing. The first part of the thesis is concerned with technologies modifying metal surfaces. An analysis of LCA technology was executed and a technological process was described. As a part of theoretical part, a description of available methods evaluating environmental impact was made. According to description the LCA methodology was chosen. In practical part of the thesis an analysis of material and energetic inputs of each process was made.

Assesment of the Environmental Impact in the Design of Production Machines in Terms of Greenhouse Gas Emissions of Selected
Krbalová, Maria ; Pačaiová,, Hana (referee) ; Demeč, Peter (referee) ; Blecha, Petr (advisor)
The presented doctoral thesis is focused on environmental impact assessment of basic engineering materials used in a production machine construction. Ecological profile of the machine itself develops already in the phase of its design. It is not only about the choice of future machine parameters and materials that it is built from, but also about technologies used for its manufacture and operation conditions of the finished machine (consumption of energy and service fluids). The thesis occupies in detail with environmental impact analysis of the production machine design from the viewpoint of material production that mentioned machine consists of. The output from the performed analysis is methodology for evaluating of machine design from the viewpoint of greenhouse gas emissions. Created methodology enables evaluating of machine ecological profile and its possible adjustments even during pre-production stage. In the first part of the thesis the analysis of current legislation in the field of fighting against climate changes, reducing of products energy consumption and increasing of production machines energy efficiency is presented. Also in this part of the thesis description of methods that were used to achieve thesis goals is stated. Furthermore analysis of production machine as a system of structural components that fulfil the certain functions and description of used basic engineering materials are presented. The second part of the thesis is devoted to environmental impact analysis of the production machine design process. There the design process and environmental impact of machine design are described. This is followed by description of production machine life cycle and detailed analysis of undesirable substances emissions emitted during pre-production phases of machine life cycle (i.e. during the raw materials extraction and materials production). From this analysis the particular constituents’ pre-production phases which are sources of undesirable substances emissions (e.g. greenhouse gas emissions) were derived. The thesis also includes analysis of these constituents’ life cycles and description of electric power generation as a basic constituent of any phase of product life cycle. In this part of the thesis calculations of particular fuel type’s amounts that is required to produce 1 MWh of electric power and carbon dioxide amount produced during electric power generation are presented. The third part of the thesis contains created models of manufacturing processes of basic engineering materials and calculations of related emissions of selected greenhouse gases. The practical output from this part of the thesis is methodology that enables environmental impact assessment of machine design from the viewpoint of engineering materials used in its construction.

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.

Hodnocení environmentálních dopadů při produkci vybraných olejnin
PLÁNSKÁ, Miroslava
The diploma thesis deals with the evaluation of the environmental load, which is related to the standard cultivation practices of oil crops (sunflower - Helianthus annuus, oilseed rape - Brassica napus, hemp - Cannabis sativa) by using the life cycle assessment method. The work deals with the comparison of these oil crops in the case of the production of 1 liter of potentially extractable cooking oil. For the purposes of the work, the functional unit of production (1 liter of oil) and the unit of area (equivalent unit of area needed to obtain the same amount of oil) were deter-mined. In the evaluation of environmental aspects, within the selected impact cate-gories, the greatest environmental load was associated with the production and use of fertilizers, the use of chemical plant protection, and agrotechnical operations.
