Proven path to profitable recycling of low value polyester and PET waste.
Process for large scale recovery of mixed polyester and PET waste back to high grade polyester materials through catalytic glycolysis.
Patented heterogenous catalyst and process for lowest cost recycling of mixed polyester fiber waste.
Waste to BHET demonstration plant in Sweden
POC batch capacity: 100 kg
Demo phase continuous capacity: 2000-3000 ton/year
What is glycolysis.
Rewins process is based on glycolysis which is the reversal of a standard production step in the industrial manufacture of PET. Glycolysis uses MEG as reagent splitting the polyesters polymer into monomers allowing for effective removal of contaminants using a minimum of energy.
The purified BHET monomer can then be re-polymerized in existing polyester plants and used of manufacture of new fiber and plastics materials:
