| titleOfInvention | PROCESS THAT INCLUDES GLYCOLYSIS AND SUBSEQUENT PURIFICATION FOR THE RECYCLING OF POLYESTER MATERIALS. |
| abstract | A new process for recycling polyesters is described. In accordance with this process, consumer discarded polyester pedaling is reacted with glycol to produce a low molecular weight monomer or oligomer by depolymerizing the polyester. The monomer or oligomer, as the case may be, is further purified using one or more of a number of steps including filtration, crystallization and, optionally, an absorbent or evaporative treatment. The monomer or oligomer thus produced is particularly suitable as a raw material for the production of acid-based polyester, ester, or packaging grade polyester material. Because the process includes purification steps, the specifications for the previously used polyester material need not be strict. |
