Ethanol production from waste materials

Experiment was designed for ethanol production using corn andother organic waste material containing starch contents andcellulosic material while barely used for diastase and acidicdigestion methods. The effect of temperature, yeast, barely diastaseand various dilutions of acid (sulfuric acids) were investigated onethanol production. The result showed that corn yielded highamount of ethanol (445ml) as compared to cellulosic material whichproduced 132ml of ethanol from one kg of weight. It was also notedthat with the increase of barely and yeast amount in a proper mannercan increase ethanol production from different starch sources. It wasalso noted that acid dilutions affected cellulose digestion where highyield of reducing sugar was noted at 0.75% of sulfuric acid dilution.It was concluded from the present experiment that economicalsources of starch and various dilutions of acids should be tried oncellulose digestion for bio-fuel production to withstand in thisenergy crisis time.
