Field of Research
Chemical recycling of PET bottles
Chemical depolymerization of PET is performed via glycolysis. The resulting BHET monomer can be used as raw material for the production of fresh PET. This equilibrium reaction is examined experimentally as well as theoretically. By means of thermodynamic modelling the yield of BHET monomers is optimized. In order to separate BHET monomers selectively out of the reaction mixture crystallization is used.
The influence of process parameters on the efficiency of separation is determined by design of experiment. Finally, all process steps – from shredded PET flakes to pure BHET crystals – are performed one after another. Subsequently, the whole process is economically assessed.
