Explanation:

Sugar industries produce molasses from the sugar cane processing. Molasses have 50 -55% concentration of sugar in the form of sucrose, with chemical formula C12H22O11. This source of compound is used for preparing ethyl alcohol. Ethanol in the form of absolute and rectified spirit can be made from molasses. Basis raw materials for an industry to produce 1 ton of ethyl alcohol requires, molasses up to 5.6 tons, sulfuric acid 27 kg and ammonium sulphate 2.5 kg.
Bagasse is the fibrous matter that remains after sugarcane or sorghum stalks are crushed to extract their juice. It is dry pulpy residue left after the extraction of juice from sugar cane.Enzymes such as alpha- amylase and glucoamylase were used to breakdown the cellulose in sugarcane bagasse.
