ABSTRACT:
A method and an apparatus for carrying out the method are described which are used for reprocessing waste material accumulating in the production of cigarettes and similar rod-form smoking items, wherein the waste material comprises paper material, tobacco and filter material, wherein the paper material is wrapped around the tobacco, and wherein essentially the following process steps are carried out: the waste material is subjected to a dry mechanical treatment in order to obtain waste material which is broken down and in which the material components of the waste material are separated one from the other, and in particular the paper material is detached from the tobacco or the other material components, and the tobacco is subsequently sifted out of the broken-down waste material. The paper material can be suctioned out of the broken-down waste material after the tobacco has been sifted out.
