Реферат: The invention relates to a method for recycling polyesters or polyester mixtures from polyester-containing waste. According to said method, the polyester or polyester mixture is dissolved in a solvent, whereupon free-flowing particles thereof are precipitated with the aid of a precipitating agent. The precipitating agent is selected in such a way that the precipitating agent and the solvent can later be separated in a simple manner.
