Recyclation of Plastics
Lasota, Ondřej ; Němec, Karel (referee) ; Molliková, Eva (advisor)
Plastic materials thanks to their properties like strength, durability, versatility and relatively low cost has gained this much popularity. With their constantly increasing amounts contribute to the waste. Most frequent method of waste disposal is landfill, which is due to plastic’s durability undesirable and causes serious problem for the environment. This bachelor thesis focuses on the use of secondary raw materials obtained from polymer waste. Large amounts of generated polymer waste can be appropriately designed methods processed to produce fuel, to modify asphalt mix and to reinforce concrete. Different methods are analyzed and their advantages and disadvantages are shown.

Sposoby nakladania s odpadovými plastmi získanými triedeným zberom v obciach
Lunter, Daniel
In this bachelor thesis on topic Ways of processing the plastic waste acquired by sorted collection in villages I firstly chose to put down research on the issues of waste management in the terms of plastic waste. To continue, I analysed the practise of organisation Združenie BIELA ORAVA, which deals with waste collection, transport, sorting and market of the waste for sum of 24 villages in microregion Biela Orava with total population 56 793. The research done by me took place at the sorting line and picking yard of the organisation, along with the communicating with responsible persons. According to the investigation I proceeded to analysis of the spheres of plastic waste processing companies, which either assign new value to the waste by transforming it to secondary raw materials or is used for energetic value. I have discovered that the waste obtained by the organisation was primarily sold to the companies for material recyclation. The rest of waste was bought by cement factories, which used the waste as a fuel, or it was the scrap waste, which was utilized energetically in incinerator. In the end, I submitted recommendations for increased effectivity of the operation of Združenie BIELA ORAVA.
