Kolařík, Ivo ; Jedlička, Filip (referee) ; Beňo, Zdeněk (advisor)
The main objective of this master’s thesis is to develop design equipment for thermomechanical pre-treatment of biodegradable waste. An important aspect of the design is taking into account current legislation, sanitary conditions for determining the pre-treated biodegradable material, which also serves as a raw material for biogas production. So the device will be used to monitor the impact of thermomechanical pre-treatment of biodegradable waste for biogas recovery. The following describes the processes of anaerobic decomposition of biodegradable materials and technology, whose main task is intensification of anaerobic decomposition of organic materials. The theoretical work are given various methods of processing and utilization of biodegradable wastes, focusing on kitchen waste and sludge from sewage plants. The next section describes the various factors that may affect the stability of the process of biogas generation. This also results in yield and chemical composition of biogas. A key part of this master’s thesis is to develop technical documentation and an approximate calculation of the hot slurry.

Draft logistic model collection of biodegradable waste in the selected region.
SOUKUP, Radim
This thesis concentrates on the collection system of biogadable waste in a chosen locality. The method deals with the realization of a logistic model of biogradable waste in a locality. The introductory part provides a description of particular system of biogradable waste collection. The following part describes the calculation method and setting the particular parts of the system. The suggestions include descriptions and present experience with introducing this system in practice. The thesis describes the logistics of biodegradable waste collection for its further use. The collection is realized in three towns in Prachatice region. A technical estimate and calculation helped to determine the annual production of biodegradable waste depending on the feature of the origin. The calculation was made on the basis of ascertained data about well-kept municipal places, number of homes, areas and gardens. Considering the prevailing origin of biodegradable waste there was determined a delivery system of collection to a waste collection place with an aside container. Based on the total volume of ascertained production there was determined the capacity of containers in each town. According to the predicted capacity of the container, there were set the collection times and replacements done by an appropriate transport carrier. After researching the trails suitable for container transport there was chosen an optimal trail for collecting and accumulating the biodegradable waste. The choice of a landfill site originated from the real landfill site of municipal waste where the selection of biogradable waste was realized. The transport carrier which realizes the containers collection from the towns is located on this landfill site.

The Problematic of Biodegradable Waste in the Regions of the Czech Republic
SMRČINA, Tomáš
The goal of this thesis is to describe the issue of biodegradable waste, including its legislative act and the possibilities of other usage of biodegradable waste as unburdening products. The main aim of this thesis is to complete the logistic model for the delivery transportation of agricultural biodegradable waste. The concept of compost for the city Milevsko and its catchment area is made according to acquired figures from calculations. In the concept of compost was applied the figures from the acquired sources and the data related to the amount of the production of biodegradable waste in Milevsko during the year 2010. In relation to the acquired results was accomplished the economical evaluation of costs and revenues for the compost and its rate of return in the next years. For the city Milevsko is this topic current because this issue is not resolved here at all. The acquired findings from the economical result of the compost concept is summarized in the conclusion of the thesis.
