Environmental Impact Assessment for Chosen product
Durda, Tomáš ; Řezníčková, Hana (referee) ; Krbalová, Maria (advisor)
The Master´s thesis is structurally divided into the theoretical and practical part. In the theoretical part, the author describes current global environmental issues and the impact of the industry on the environment. The current state of the environmental legislation in mechanical engineering, environmental management systems, and methodologies of an environmental impact assessment are described. The practical part deals with the environmental burden of the snowboard production process according to the LCA method. Life cycle inventory is performed to evaluate individual materials whose production is the most environmentally damaging. At the last stage, possible measures are proposed to reduce the environmental burden.

Fluidized-bed Combustion of Dry Stabilized Sewage Sludge in Oxy-fuel Mode
Moško, Jaroslav ; Pohořelý, Michael ; Durda, Tomáš ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel
Sewage sludge is an inevitable waste stream from wastewater treatment and its disposal is complicated due to specific characteristics of its composition. Sewage sludge combustion/incineration is the only suitable way for disposal of large volumes of sewage sludge containing POPs and some heavy metals. Sewage sludge combustion reduces the volume of such waste and causes destruction of organic contaminants. Oxy-fuel combustion is a technology for simplifying CO2 sequestration from the flue gas by using nearly pure oxygen instead of air for the combustion. In order to control the combustion temperature, part of the flue gas is recycled to combustion chamber. The paper brings information about investigation of the effects of combustion temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB combustion of sewage sludge. The experimental results have shown that an increase in combustion temperature leads to an increase in NOx and to a decrease in N2O emissions in the temperature range 750–930 °C. The lowest SO2 emissions were measured in the temperature interval from 800 to 820 °C in all experiments with different oxygen concentration in inlet gas. It was found that when the oxygen concentration in inlet gas increased, the emissions of SO2 increased while emissions of NOx slightly decreased.
