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.

Hazards and Safety
Dust is flammable. Inhalation of dust may cause pneumonitis or asthma.
Paper fiber type: Non-woody/grass. Using transmitted light microscopy, fibers are flat and thick-walled with mostly blunt ends. The have the appearance of hardwood fibers. Parenchyma cells are very large, thin-walled and abundant. Heavily pitted long vessels are also present, but may be broken up by pulping. Separated spiral thickenings may be presnet . Appearance with Graff "C" stain: Dark blue, but varies with bleaching. Average dimensions of fibers: length, 1.7mm; width 20μm. Vessels can be up to 2.1mm long and 200μm in width. Common pulping method: mechanical or soda.
