Abstract
A method for utilizing waste cellulosic material by conversion to sugars suitable for use in tobacco manufacturing is disclosed. The method comprises comminuting waste cellulose products, which are generated during tobacco product manufacturing, deesterifying any waste cellulose acetate present in the waste products, enzymatically saccharifying the deesterified and comminuted products to simple sugars and recovering the sugars produced. The recovered sugars may be utilized in tobacco treatment processes. Enzymatic saccharification is preferably effected with Trichoderma viride cellulases.
