Description

Originally, the term bagasse was applied to any residual fibers from the processing of numerous plants and fruits such as olives, palm nuts, grapes, Sisal, sugarcane, and sugar beets. Currently, the term bagasse only refers to the dry, fibrous residue left from the stalks of sugarcane, Saccharum officinarum, after the sugar has been extracted. Bagasse is composed of Cellulose (50%), pentosan (25%) and Lignin (25%). It is used in the production of Paper pulp, fiberboards, Insulation, Acoustical tile, and animal feed.
