Pohořelý, Michael ; Durda, Tomáš ; Moško, Jaroslav ; Šyc, Michal ; Kameníková, Petra ; Zach, Boleslav ; Svoboda, Karel ; Hartman, Miloslav ; Beňo, Z. ; Parschová, H. ; Houdková, L. ; Punčochář, Miroslav
The paper summarizes significant fuel-energy and physico-chemical properties of stabilized sewage sludge. Sewage sludge as a fuel is characterized by high proportions of water content, volatile matter content, ash content and a considerable amount of reactive, organic nitrogen (2-5 wt. % of dry matter). In addition to oxygen; silicon, phosphorus, aluminum, iron and calcium are the most abundant elements in the ash from the sludge. The lower calorific value of dry, anaerobically stabilized sewage sludge is 9-12 MJ kg-1 and it corresponds to a low calorific value of lower-class subbituminous coal or lignite.

Sorghum as the energy crop
CIBULKOVÁ, Renata
Sorghum, one of the world's major cereals, is the most commonly used for food or fodder. The aim of this Bachelor thesis is in a form of literary review to summarize information about the properties of sorghum in view of energy use, energy yields, the cultivation technology for energy purposes, the possibilities of using sorghum for energy purposes and the situation in the world and the Czech Republic. Recently sorghum has been tested as a raw material for all branches of the energy industry because of the wide range of potential products such as ethanol, hydrogen, methane, lipids, acetone, butanol and lactic acid. Sorghum can be used as biofuels due to the relatively high yields of phytomass. Utilization of individual species of sorghum depends on their chemical composition that can be significantly influenced by climatic conditions and way of cultivation. Crops improvement plays an important role for increasing production and utilization of this cereal in all climatic conditions.

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.
