Tiivistelmä
The focus of this thesis is the removal of halogens from a plastic mixture in pyrolysis. This research is significant in the context of sustainable recycling, and it addresses the problems that are faced with polyvinyl chloride (PVC). This plastic type contains harmful halogen compounds. The study involves a comprehensive investigation of different methods for halogen removal. This means exploring the effect of adsorbent and reaction parameters. The purpose of the experiments is to understand how to enhance the efficiency of halogen removal during pyrolysis and to develop better recycling methods.
The planned work included various experiments under different conditions with and without the use of adsorbent to understand what can optimise and improve the efficiency of the product. On the basis of the results, it was concluded that the use of adsorbent and precise parameters had a positive effect on the result. Further experiments should be performed to clarify whether the results are optimal.
This research was conducted as part of Urban Mill project and its experiments being conducted at VTT. The outcome of this thesis is gaining valuable information of sustainable recycling especially PVC and other halogen-containing plastics.
