Molasses is the only by-product obtained in the preparation of sugar through repeated crystallization. Molasses is mainly used for the manufacture of alcohol, yeast and cattle feed. Alcohol in turn is used to produce ethanol, rectified spirit, potable liquor and downstream value added chemicals such as acetone, acetic acid, butanol, acetic anhydride, MEG etc.
Bagasse is a fibrous residue of cane stalk that is obtained after crushing and extraction of juice. It consists of water, fibre and relatively small quantities of soluble solids. The composition of bagasse varies based on the variety of sugarcane, maturity of cane, method of harvesting and the efficiency of the sugar mill. Bagasse is usually used as a combustible in furnaces to produce steam, which in turn is used for power generation. It is also used as a raw material for production of paper and as feedstock for cattle. By making use of bagasse sugar mills have been successful in reducing depends on State Electric Boards, for their power supply as it can procure up to 90-95% of its total power requirement through captive generation from steam turbines.
Fly Ash is the residual output from the boiler furnace after bagasse has completely burnt out. This fly can be used as a raw material for brick manufacturing.
