Beschreibung
Zusammenfassung:	The invention relates to a method for recycling polyesters or polyester mixtures from polyester-containing waste, in which the polyester or the polyester mixture is dissolved in a solvent and subsequently free-flowing particles are precipitated herefrom with a precipitant. The precipitant is thereby chosen such that subsequent separation of precipitant and solvent is made possible in a simple manner.
