Abstract: Sunflower husk consists the primary and secondary plant nutrients—phosphorus (10.94% P2O5), potassium (25.84% K2O), calcium (19.07% CaO), magnesium (18.58% MgO), and also some micronutrients (zinc, copper, cobalt, manganese, iron, and molybdenum). The sunflower husk has low plasticity, and the granulation process occurs better when binding materials (sugar factory lime, molasses, urea formaldehyde resin) are used. Sun flower husk is a polysaccharide source that can be converted to reducing sugars. Sunflower husk was hydrolyzed using sulphuric acid (0.2N) at a temperature of 65&degC - 70&degC. It was observed that the degradation has significant effect with respect to amount of husk taken and in turn sugar yield is around 40% - 50%, each of which is estimated by Bertrand’s, Benedict’s and Lane-Eyon method.
