Úpravy biodegradabilních odpadů ze zahradnictví pro energetické využití
Doležal, Daniel
This work deals with defining garden wastes and their processing for energy products by pelleting and briquetting. This work compared a briquetting production line and a pelleting production line. Based on technical and economic data, the production costs for 1 t of briquetts/pellets were assessed and as a partial task, the economic profitability was assessed. As emerged from the results, when having similar purchase and production costs, pelleting is more efficient in a ratio of 2 : 1.

Utilization of biomass for the energy purposes
Romanová, Kristýna ; Ing.Ondřej Kosík, Ph.D. (referee) ; Flodrová, Dana (advisor)
The theoretical part of work focuses on the issue of biomass used for energy purposes, in particular agricultural waste, which can be used as a substrate for biogas station. Furthermore, examines the composition of polymer substrates, which affects most biogas process. The aim of this work was to measure each sample of enzyme activity of biomass, which is used as a raw material for biogas plants.
