Bagasse, also called Megass, fibre remaining after the extraction of the sugar-bearing juice from sugarcane. The word bagasse, from the French bagage via the Spanish bagazo, originally meant “rubbish,” “refuse,” or “trash.” Applied first to the debris from the pressing of olives, palm nuts, and grapes, the word was subsequently used to mean residues from other processed plant materials such as sisal, sugarcane, and sugar beets. In modern use, the word is limited to the end product of the sugarcane mill.
