Deposit refund system as a key tool for circular economy
Patka, Vojtěch ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
This bachelor´s thesis deals with the issue of PET packaging, more precisely PET beverage bottles, and with a possible solution to this issue using Deposit Refund System, reffered to as „DRS“. When comparing the current situation of PET beverage bottle management with the set targets and legislation of the EU and the Czech Republic, it can be concluded that it is necessary to adjust the approach to this part of waste management. The modern approach is the approach of so called circular economy, which considers waste as a potential source of material for re-production. DRS is a tool of circular economy which indicates high collection rate of PET beverage bottles in EU, i.e. the proportion of bottles returned and bottles placed on the market. However, DRS is only part of the overall PET beverage bottle management system which requires an efficient processing chain to function properly. The chain is described in detail from returning the used bottle to the production of a new one. A significant benefit in this chapter is the information obtained in interviews with experts from practice and during visits to production lines for PET preforms and PET bottles. The thesis is concluded with a SWOT analysis of DRS in the Czech Republic where the deposit system is likely to be introduced at the beginning of 2026 and its introduction is currently being widely discussed.

Design of a new production line
Hejl, Martin ; Jurová, Marie (referee) ; Juřica, Pavel (advisor)
This diploma thesis deals with the project of implementing a production line in a selected company dealing with the recycling of plastic waste and the production of rPET flakes as a secondary raw material for the production of plastic products. First, it deals with the description of the current state and the production process in the company, including the layout of the equipment, and then defines the requirements for the project by the management of the company and individual shareholders of the company. Defining the requirements for the project and at the same time the method of obtaining key information took place on the basis of in-depth interviews with the interested parties of this project, while a pilot design of the layout of the machinery was created, including a description of the technology and a flowchart of the required production process. The main content of the design part is the creation of a proposal for a possible implementation of the production line using a network diagram using the PERT method, which indicates that the duration of the project was calculated to be 106.6 days. Together with the network diagram of the project, an analysis and proposals for managing the risks of this project were prepared. At the end of the draft chapter, a financial analysis of the project's payback period was carried out, as the condition of a payback period of 3-5 years must be met in order for the project to be approved by the shareholders, which this project fulfilled in all three expected progress scenarios.

Evaluation of Polymer Separation System Purifier N 1024 device efficiency
Duliková, Michaela ; Charvátová,, Michaela (referee) ; Čáslavský, Josef (advisor)
In this Diploma Thesis the recycling of the PET bottles in the company PETKA CZ, a.s. is under focus. Thesis describes the Italian technology AMUT designed for physical recycling of the PET bottles. The primary goal is the quality of the final recycled product, PET flakes, particularly in the context of undesirable admixtures such as PVC, other polymers and impurities. Due to the deteriorating quality of the PET flakes the equipment Polymer Separation System Purifier N 1024 has been tested, which had significantly reduced admixtures in PET flakes. As it turned out, the current procedures for solving problems with the PET flakes quality are no longer sufficient.

Effect of flash ads on the environment and its comparison with the production of PET bottles
Krejčí, Martin ; Koblovský, Petr (advisor) ; Rod, Aleš (referee)
This bachelor thesis examines the impact of online advertisments created using Flash technology on the environment in the U.S. and then compares it to influence of production of PET bottles on the environment in the U.S.. The thesis describes the functioning of the flash ads. In the analysis there are compared the carbon footprint left-out of the difference in electricity consumption in the enabled and disabled Flash ads and production of PET bottles. The aim of the analysis is to compare the costs of flash advertising and PET bottles in term of environment and to consider revenues resulting from them and to answer the question whether the flash advertisement market is not regulated only because it does not seem originally to damage the environment as much as PET bottles does, and if it should not be regulated.
