As a part of the activities carried out in the action A2. Adjustment of the demonstrative  catalytic glycolysis pilot experiences reproducing the BHET monomer from polyester textile wastes, the design and simulation of the catalytic glycolysis process has been completed. On the bassis of the data provided by GAIKER-IK4 in the pilot plant tests and using the software Aspen Plus, BETA has simulated the different stages of the catalytic glycolysis process, optimizing the technical and operational parameters of the process PET2BHET.
