Converting Waste Banana into Bio fuel Using Membrane Technology

Combustion of the fossil fuels at the current rate would contribute to the environmental crisis globally. Bio-fuel recognized as alternative to fossil fuels, India contributes to 27% of world's banana production. 25 to 40% bananas wasted due to bad handling, Waste banana can be used to produce bio-fuel. Production of bio-fuel is studied by enzymatic hydrolysis and fermentation by using Saccharomyces cerevisiae. Utilization of rotten banana is more suitable for bio-fuel production as renewable energy which could reduce the cost of initial process. Although several separation technologies are technically capable of removing volatile products from fermentation broth, distillation requires more energy and cost. Pervaporation has been used as an alternative to classical separation process as distillation. It is an attractive technology because of the potential to selectively separate volatile component and water. and energy intensive, economical, safer separation technology.Hydrophobic PTFE (Polytetrafluoroethylene) Membrane of porosity 0.2 micron is used for Pervaporation of Bioethanol-water. The separation processes have many advantages that can improve the total efficiency of bioethanol production refineries.
