Utilization of biodegradable waste
Švec, Jan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this paper is to summarize the current situation of the problem using biodegradable waste. The introductory chapters deal with descriptions of different types of biodegradable waste. The main part describes ways of handling this waste. For various types of waste are listed by their most appropriate treatment and further use. Emphasis is placed on legislation dealing with that waste legislation on the processing equipment.

Kitchen Waste Fermentation
Dlabaja, Tomáš ; Jícha, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
Biodegradable waste is a significant type of waste, which includes kitchen waste from restaurants, catering establishments and kitchens as well. This work evaluates a waste production in the Czech Republic and compares it with a waste production of other European countries. It provides a brief search through legislation and analyzes present development, going from simple disposal of material to energetic and material utilization. New laws has established stiffer requirements for the treatment of dangerous biowaste including kitchen waste. Under all these changes benefits of the most suitable ways of waste treating are analyzed. Part of the work is a laboratory experiment of the biogas yield, which verifies theoretical assumption of kitchen waste utilization at anaerobic fermentation. In conclusion the economy calculation of such manufacturing plant is done.

Community vermicomposting of biodegradable municipal waste
Klubalová, Kateřina ; Innemanová, Petra (advisor) ; Hnátková, Tereza (referee)
The method of vermicomposting experiences a big boom nowadays. The people living in flats can process bio-waste, which they produce on their own. Therefore, the amount of biodegradable municipal waste contained in the dumped mixed municipal waste slightly reduces. In addition, people can benefit from high-quality products called vermicompost and its leachate called worm tea. In this work I summarize acquired knowledge about the vermicomposting focusing on kitchen waste, about conditions, which this method demands, about composition and the possibility of using the end products. Also, it is discussed which bio-waste is suitable for vermicomposting and what earthworm species can be used. The theoretical side of using worm tea in the hydroponic cultivation of plants is discussed. The toxicity of different concentrations of worm tea on a seeds of Sinapis Alba was tested in the experimental part. The concentration row 2,5; 5,0; 7,5; and 10,0 vol. % of four different samples of worm tea from different bio- waste was used. Distilled water was used as a control solution. The values of inhibition for each concentration of worm tea were calculated. Available literature recommends to dilute worm tea in ratio of 1:9 with water. However, the results showed that this dilution is already inhibitory for some...
