Abstract
Tobacco in cigarettes rejected in the cigarette manufacturing operation is recovered by subjecting the cigarettes to a series of ripping actions which open the wrappings to expose the tobacco and a series of screening operations which result in effective recovery of 99+% of the tobacco and with almost no presence of wrappings residue material in the recovered tobacco, the wrappings material being separated to a different collection end point than the recovered tobacco.
