Chapter 13: Problem 2

What are bagasse and vinasse?

Short Answer

Expert verified

Answer: Bagasse is the fibrous byproduct generated during the sugar extraction process of sugarcane or sorghum stalks, used as a biofuel and in the production of various materials. Vinasse is a liquid byproduct from the fermentation and distillation processes of alcohol production, employed as a fertilizer in agriculture or as a substrate for biogas production.

Step by step solution

Define Bagasse

Bagasse refers to the fibrous byproduct generated during the sugar extraction process of sugarcane or sorghum stalks. The sugar extraction involves crushing the sugarcane stalks, which results in the separation of sugar-containing juice and this residual fibrous waste material called bagasse. It is mainly composed of lignin, cellulose, and hemicellulose. Bagasse is widely used as a biofuel for cogeneration of heat and electricity, as well as in the production of paper, pulp, and various other materials.

Define Vinasse

Vinasse, also known as stillage, is a liquid byproduct generated during the fermentation and distillation processes of alcohol production, particularly ethanol and other alcoholic beverages. It is composed of organic matter, soluble salts, and water. It contains a variety of nutrients and organic elements, which makes it suitable for usage as a fertilizer in agriculture or as a substrate for biogas production through anaerobic digestion.
