Novel Pre Treatment Techniques for Extraction of Fermentable Sugars from Natural Waste Materials for Bio Ethanol Production

The demand of traditional/domestic fuel is increasing day by day. Bio ethanol, a non-conventional source of energy is a solution to this problem. India stands second in sugarcane production worldwide, so a huge amount of agriculture waste residue is produced. This study presents the extraction and analytical estimation of cellulose and hemi cellulose of sugarcane bagasse and extraction of soluble sugars from it for bio ethanol production. At first samples were prepared and analysed for bulk density moisture content, ash content, volatile matter content, fixed carbon content and calorific value. Cellulose and hemi cellulose estimated after the treatments suggested their efficient extraction from the sugarcane bagasse. Different pre treatment technique are performed to increase the amount of fermentable sugars and to decrease the lignin content present in bagasse. Then the pre-treated bagasse is placed for enzyme hydrolysis followed by fermentation to produce bio ethanol. The result suggested that waste bagasse can be used as a renewable source of energy for bio ethanol/bio fuel production in an environmentally sustainable and economically viable way.
