A process for recovering and recycling tobacco dust comprises the steps of:
€¢ mixing tobacco dust with a binder to provide a paste;
€¢ extruding the paste through a die to provide an elongate extrudate;
€¢ slicing the extrudate at one or more discrete locations along its length to provide a plurality of extrudate portions; and
€¢ pressing at least one extrudate portion between two opposed surfaces, so as to flatten it. |
