Recyklace PET lahví

Abstract

The thesis deals with the possibility to recycle PET bottles, mainly with transformation of the waste polyethylentereftalate by heat decomposition without the presence of oxygen. The theoretical part of the thesis consists of a general overview of possibilities to transform waste PET, followed by a chapter describing the actual recycling technology and the current state of recycling in our country and around the globe. Furthermore, chapters on pyrolysis of PET and processing carbon skeleton are included which follow the experimental part of the thesis. In the experimental part, pyrolysis of waste PET is described as well as the possibility of processing carbon skeleton as a product of the recycling, focussing on activation by ozone. The purpose of the thesis was to describe recycling PET bottles by heat decomposition without the presence of oxygen and suggest possible use and processing of the outcoming products of the recycling, mainly carbon residuum, which turns out to be a very interesting product.
