Abstract
Tobacco material can be processed to yield a product (e.g., sheet-like material) which can be used to yield cut filler for the manufacture of cigarettes. Tobacco material (e.g., whole leaf and/or scrap) is shear agitated in the presence of moisture of less than 30 weight percent. The shear agitation is performed in the absence of externally added binding agents. The sheared mixture is passed through a roller system in order to provide compressive treatment to the mixture. The processed mixture is further formed into the desired shape. Tobacco material can be provided using energy efficient processing steps, and without waste of tobacco material.
