Mobile Machineries Used for Modification of Agregates and Recycled Materials from Building Waste
Turčinek, Andrej ; Horsák, Milan (referee) ; Škopán, Miroslav (advisor)
This bachelor's thesis deals with the problem of selection of a new crusher for a smaller recycling company and the comparison of the old variant of the production line with the new one thanks to the increasing part of recycling in the construction industry. In the introduction, this is a general overview of the technological line, the requirements for aggregates and types of crushers. The actual work consists in acquainting with a specific technological line for the treatment of the construction waste, the selection of suitable substitution for this line and the subsequent comparison of the old and the new variant. As it is a relatively new industrial sector with rapid development, the main benefit of the thesis is the outline this industry sphere in 2017.

Effective proposal and operation of recycling line as an element in waste management
Dufka, Martin ; Janošťák, František (referee) ; Gregor, Jiří (advisor)
This master thesis deals with the current situation of waste management of material usable municipal waste with focus on various fractions of plastics. The theoretical part summarises the legislation of waste treatment, also contains an analysis of the current situation of waste management in the Czech Republic and comparison the situation in the European Union. In the next part of thesis are described basic fractions of plastics and their properties. There are mentioned the current problems with plastics processing and the risks of leakage to the environment. Furthermore, a complex chain of plastic waste reprocessing is described, since the inception of plastics waste to the manufacture of products made from recycled plastics. The most attention is paid to the discription of recycling plant, where the output material from sorting lines is reprocessed into a secondary material in the form of flakes or granules. Also this part is focused on the technology of recycling line and the individual devices are described. In the practical part of the thesis is created techno-economic model of recycling line with the aim of its use for balance calculations of recycling and also economic evaluation. As a part of the model was made a market research of secondary raw materials with a focus on price development. Subsequetly, sensitivity analyzes of selected parameters are applied to the model and the impact of scenarios on the economic results are evaluated.
