Acquiring of phosphorus from sewage sludge
Boubínová, Marie ; Chorazy, Tomáš (referee) ; Hlavínek, Petr (advisor)
The diploma thesis is focused on phosphorus recovery from sewage sludge. In the first part of the thesis, research of phosphorus recovery from sewage sludge is explained. Reusing of phosphorus, a critical material of mankind, is expressed with the principles of the circular economy. The second part of the thesis defines the potential of phosphorus extraction from sewage sludge from medium-sized (Trutnov WWTP) and large (Modřice WWTP) wastewater treatment plant and a technical and economic study of the proposed phosphorus recycling system at these wastewater treatment plants is described.

Energy use of biomass
Střecha, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The main task of this thesis is the research of different types of biomass, description of each technology subsequent to obtaining thermal energy for central sources of heat and the mapping of use biomass in a cogeneration production of electric energy and heat. The first part of this thesis deals with the creation and definition of biomass, chemical and physical properties, basic distribution and showing examples of individual representatives. The next part of this thesis describes various options of energy usage of biomass subsequent to obtaining energy for central sources of heat. The last part is concentrating to individual power units in Czech Republic, which exploiting biomass for cogeneration production electric power and heat.

Technologies for energy use of biomass
Záviška, Radek ; Škvařil, Jan (referee) ; Moskalík, Jiří (advisor)
The objective of this work is developing retrieval technology of biomass energy. In the introductory part of the work deals with the definition of biomass, including ways of producing machines for the production and transportation. The main part of the thesis deals with the technology converts raw biomass into valuable energy products. Processing takes place in a straightforward manner the thermal and electrical energy or biomass is indirectly evaluates the products of higher quality, which further downstream processing operations. The indirect processes occur valuable usable energy output in transport, buildings, agriculture and many other industries.

Microwave induced pyrolysis of biomass
Šmarda, Marek ; Gal, Pavel (referee) ; Jícha, Jaroslav (advisor)
In this bachelor thesis there are informations about different methods of processing organic nature substrate with a focus on a waste processing using microwave pyrolysis. In sum it is possible to say that microwave pyrolysis is a progressive solution to process waste substrate. Due to evenly and rapid heating of organic nature substrate, this method is more effective compared to conventional methods of waste disposal. The result of this work is to submit information on processing waste substrate in the form of microwave analysis and subsequent economic evaluation.

Energy use of biomass
Holečková, Michaela ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of this bachelor thesis is the research of different types of biomass, description of the various types of methods and technologies for energy usage of biomass and the mapping of large power plant units in the Czech Republic. The first part of this thesis deals with the definition of biomass, its distribution and the description of basic essential attributes describing its composition. The downstream part of this work is focused on the technologies of gaining energy out of biomass or its possible conversion into other products depending on the currently discussed type of technology. The last part deals with energy balances of biomass in the Czech Republic and focuses on individual companies who use biomass as an energy source, by applying one of the methods mentioned in the previous part.

Distribution of the Organic Matter in a Sample of Biochar
Novotný, Maximilián ; Enev, Vojtěch (referee) ; Kalina, Michal (advisor)
This bachelor’s thesis is focused on characterization of the content and distribution of organic matter in a sample of biochar. For these purposes, the organic matter from a biochar sample was isolated using two procedures, specifically sequential chemical fractionation, and alkali extraction. Prepared samples were characterized by elemental analysis and thermogravimetry. Analysis results showed that sequential chemical fractionation brings higher yields than alkali extraction, moreover, it provides more detailed image of organic matter in biochar thanks to obtained separated fractions according to their linkage to the original biochar matrix. Secondly, studied biochar has a great potential as soil supplement, it contains almost 70 % of organic carbon, whilst isolated amount, which is available represent only small amount, the rest is strongly bound. On the other hand, the study showed that this specific biochar has rigid structure, which brings benefits in the context of using biochar in agriculture in long-term consideration.
