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. In order to separate BHET monomers selectively out of the reaction mixture crystallization is used.
For an efficient process, both upstreaming (depolymerization) in terms of reaction conditions (e.g. temperature, solvent use, concentration ratios) and downstreaming (crystallization, solid-liquid separation, washing) are being optimized in order to develop an economical process. A techno-economic and life cycle analysis will also be carried out.
