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.
