Production and quality of compost from the perspective of agrochemist and of processor of organic waste
BROUČKOVÁ, Vlasta
In the thesis explains the conceptual difference between primary and compost organic matter, compost and defined its organic matter and compost understanding the distinction in terms of farmers and processors in terms of organic waste. Then the development of composting and research results in recent years. The result of work revealed that the quality compost with plenty of humus substances and high ion exchange capacity can be produced while respecting the principles of real composting, but with a long fermentation time.

Current technologies and landfilling of waste and its prospects in the Czech Republic
VELEK, Jindřich
This bachelor thesis deals with waste management in the Czech Republic, especially landfilling. Different types of landfills, their technical aspects and methods of depositing waste are described. The thesis also describes the main legislation concerning waste management in the Czech Republic and tries to point out material and energetic use of waste before landfilling. Recycling is considered to be important because it decreases the amount of waste stored in landfills. Composting and anaerobic digestion are the other methods of disposal. The thesis also describes the possibilities of usage of the landfill gasses with the help of cogeneration units. The thesis refers to current level of waste landfilling in the Czech Republic and predicts the future development.

Comparison for small mechanization used in composting
TŮMA, Jan
The aim is to create a comprehensive overview of mechanization used for composting and select appropriate criteria based on analysis for comparing different types of machines. By course of each operation of composting process were selected suitable means of mechanization for composting line. Thereinafter thesis defines the mechanization by load. In the thesis is realised research availability of small mechanization on the present market and based on analysis of the data was proposed criteria for comparing different types of machines. Final part of thesis includes simple example of project compilation of composting line for small compost-processing plant. The results of this thesis can assist during selection of small mechanization for small compost-processing plants, for example for municipal needs or primary sector (agriculture and forestry).

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.

conversion of biodegradable waste into pollution-free products
PUFR, Josef
This thesis deals with the conversion of biodegradable waste (BDW) into pollution-free products. The introduction addresses the specification of BRO, collection and identification of waste in the catalog and then the main means of transformation. The second part deals with the main objective of the proposal in Chýnov composting. This project involves collecting information, selecting a suitable location, design, technological lines, select the appropriate technical means, but also in the calculations of the composting area and its economic evaluation. Given the need to address this problem in Chýnov, it is likely that this proposal will be based on an actual project.

Analysis of biodegradable communal waste disposal system in the city of Zlín
Přikrylová, Jana ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
This thesis discusses the disposal of the biodegradable communal waste (hereinafter BRKO) in the city of Zlín. In the beginning it introduces the general terms and keywords and legal regulations concerning waste disposal. It mentions environmental effects of the BRKO dump, and also ways of collecting and further treatment of BRKO. The main part of the thesis describes the current BRKO management system in the city of Zlín and based on the projects that have been completed up until now it analyses management efficiency. The thesis shows an expected progression in the total amount of BRKO in the following years due to the new limits placed on BRKO dump by the Plan of Waste Management Program. Based on the collected data, this thesis proposes an optimal solution for waste collection and waste treatment in the city of Zlín and evaluates the environmental and economic benefits of the suggested waste management system.

The design of the production of biogas from fresh grass.
ŽIVNÝ, Jakub
Work is concered with the biogas production from the fresh grass mass, which come up when the grass is being cut on regular basis in the parks and side parts of communities and cities. There is a detailed description of the biogas production defined in the beginning of the Theses in the literature overview. Next, we define the material properties suitable for the biogas production, concerning on the grass mass. In practice, there is a prototype example showing how the biogas station could manipulate the fresh grass mess in real, linked to the harvest line.

Possible utilization of grass material
KOBERNA, Daniel
The objective if this degree work is creating a survey of possible uses of surplus grass material which is caused by animal farming reduction and by bringing the ground in less fertile areas of our country to a standstill. In the work possible uses of the grass are described, especially its use in the energy industry as a fuel source for the production of heat and biogas. Classical usage of the grass material as a food source for livestock or for the production of compost is described here as well. Examples are shown there of energy kinds of grass, which seems to be a promising renewable resource of biomass for favourable economic results. The harvest of the grass material and its consequent prossesing is done by production lines, that is why a survey of such lines and their economic figures connected with the operation of these machines is also included in this work. The economic part of this work contains many formulae that can be used for counting out all the costs connected with the operation of the grass harvest machine and for evaluating the effectiveness of the return on investment into this machine

Possibilities, methods and technological processes of composting biomass
KOPAČKA, Michal
Nowadays maintained areas of greenery are an inseparable part of towns and villages. Public property belonging to the town České Budějovice is necessary to keep also. Problems arise with processing and storing biomass. One possibility of processing biomass is composting. Methods, technological processes and last but not least functional variants of composting components were developed in this paper. The composting components will ensure quality and maximum flexibility of produced compost. The projected technological line will ensure enough capacity for composting biomass in the years to come. The economic evaluation made showed that produced variants of compost are competitive.
