Abstract

The invention relates to a method for recycling cellulose acetate-containing material, such as a filter tow starting material which consists of cellulose acetate or at least has cellulose acetate. The method has the following steps: supplying a filter tow starting material to a pelletizing press; and pelletizing the filter tow starting material in the pelletizing press in order to convert the filter toe starting material into pellets, wherein the converted pellets have a higher density than the supplied filter tow starting material, and the filter tow starting material, the pellets, and/or intermediate stages of the material are cooled at least temporarily during the pelletizing process.
