Zusammenfassung:	The present invention relates to the process for manufacturing specialty polyesters & co-polyesters from recycled Bis 2-Hydroxyethyl terephthalate (rBHET) derived from Polyethylene terephthalate (PET) recycled from PET scraps or waste. The polyesters/co-polyesters thus obtained are clean and of high quality which can be used for all applications but not limited to textiles, packaging, engineering and industry. La présente invention concerne le procédé pour la fabrication de polyesters et copolyesters spéciaux à partir de téréphtalate de bis(2-hydroxyéthyle) recyclé (rBHET) dérivé de poly(téréphtalate d'éthylène) (PET) recyclé à partir de déchets ou rebuts en PET. Les polyesters/copolyesters ainsi obtenus sont propres et de grande qualité et ils peuvent être utilisés pour toutes applications, mais sans limitation, aux textiles, à l'emballage, à l'ingénierie et à l'industrie.
