Environmental Protection Legislation and The Possibility of Using Waste as a Secondary Raw Material With a Focus on the Recycling of PET Bottles
Hejl, Martin ; Pavláková Dočekalová, Marie (referee) ; Kocmanová, Alena (advisor)
The aim of this bachelor's thesis is to analyze the recycling of plastics and the analysis of the recycling process of PET bottles in the company PETKA CZ, a.s. In the last analysis of the work influencing the ways to obtain input material for the production of recycling from PET bottles, management of plastic waste, proposals for improving the production of this company and at the same time the possibilities of reducing waste in the production of recycling. Furthermore, this work describes the legislative regulation of environmental protection, general principles of recycling, how to recycle the company PETKA CZ, a.s. It currently determines and at the same time how we could recycle this to use in the future.

Možnosti výkupu kovových a PET nápojových obalů v České republice
Vrána, Michael
The aim of the diploma thesis titled Repurchase options of metal and PET beverage packages under the conditions of Czech republic, is to make a proposal of deposit-based system for one-way beverage packages. The first part contains current legislation about waste management of packages. On the following pages are describe characteristics of PET bottles and aluminium beverage cans. The third part is about the deposit-based systems in abroad. Authors own part is a survey aimed on willingness of consumer to adapt for a new return system of beverage containers. Most of respondents are willing to adapt for a new deposit-based system. The next part is a proposal of deposit-based system under the condition of Czech republic. Last part is a discussion about the potential impacts of establishing the deposit-based system. My own conclusion is that the deposit-based system is not suitable under the condition of Czech republic.

Assessment of the suitability of PET flakes produced by PETKA CZ, Inc. company for the manufacture of granulates for food purposes
Šudomová, Lucie ; Kučerík, Jiří (referee) ; Čáslavský, Josef (advisor)
This thesis deals with the recycling of polyethylene terephthalate and its subsequent processing into the form of a regranulate meeting the parameters required for food use. A brief description of recycling technology, PET flake quality rating and input material contamination is provided. Additionally, legislation regarding recycling for food purposes is discussed and regranulation technologies are described. The suitability of these technologies for processing specific flake samples has been confirmed. In the experimental part, differences in the regranulate samples are compared using DSC and FT-IR. It has been found that there are no major differences between food quality samples. Tests were carried out on 200 PET bottles (bottle, label), on which the input material was divided into 16 groups. Groups that are unsuitable for recycling with this technology was defined. In addition, contaminants of the final product were examined. Their approximate composition was determined and the relationship between the labels of the bottles at the inlet and the impurities at the outlet was found. Appropriate solutions have been proposed to reduce this contamination

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.

Question of PET bottles recyclation: Current state and perspectives
Duliková, Michaela ; Stoupalová, Michaela (referee) ; Čáslavský, Josef (advisor)
This thesis is deals with the process of recycling of PET bottles from the sorting of waste up to the using of recycled material, so-called “PET flakes“. The attention is paid mainly to the process of the physical recycling. The dry recycling process is compared with the wet recycling process from the point of view of applied technology and quality with focus on the final product (PET flakes) from the wet recycling process. As the quality is concerned, presence of blockers and polyvinyl chloride, which causes the most serious problems during recycling, is discussed. Employed technologies as well as quality requirements for spinning, producing PET strapping band, recycling by the bottle to bottle form (B2B) and other possibilities of the usage of recycled materials are also described.

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.

PET Bottles in the Czech Republic
Matějovská, Jana ; Čamrová, Lenka (advisor) ; Šmíd, Jan (referee)
Práce se zabývá systémem záloh na PET lahve, o jehož zavedení v současnosti Ministerstvo životního prostředí uvažuje. Cílem práce je zjistit, zda je nutné tento systém zavádět, jaký vliv bude mít na chování spotřebitele a kdo stojí za tím, aby byly zálohy zavedeny a kdo naopak proti. Nejprve je popsána legislativa českého odpadového hospodářství, fungování systému nyní a ekonomické teorie týkající se chování spotřebitele. Dále se práce zabývá výhodami a nevýhodami systému záloh, popisuje faktory ovlivňující chování spotřebitele, zpracovává výsledky dotazníkového šetření a uvádí, které subjekty se vyslovily pro nebo proti systému a z jakých důvodů. Závěrem je rozhodnutí o tom, zda je systém pro ČR spíše výhodný nebo nevýhodný.
