Abstract: Tobacco is reclaimed from filter cigarettes by applying sufficient pressurized air to the filter end of each cigarette to eject the tobacco from the cigarettes. The method for reclaiming the tobacco involves (a) transporting a succession of filter cigarettes along a predetermined path, in a discontinuous, indexing manner, (b) temporarily engaging the filter end of each cigarette with reciprocating mouthpiece means during the pause between indexed movements and (c) applying pressurized air to each engaged cigarette via the mouthpiece means to force the tobacco from the cigarette and into a suitable collection device. Preferred apparatus is disclosed for accomplishing this method.
