Abstract:
Tropical and sub-tropical countries in Latin America, Caribbean and Asia grow bananas in large quantities. Ecuador is the world's largest exporter of bananas, producing 7.4 million tonnes annually. More than 12% by weight of the harvested banana cluster is banana peduncle, which is discarded. The idea of this project is to evaluate the feasibility of using the banana peduncle as a feedstock to produce ethanol by fermentation and/or biogas by anaerobic digestion. The analyses considered will characterize the composition, structure, chemical properties, fermentability and anaerobic digestibility of banana peduncle fiber, concentrated juice and stillage (after distillation). Results show that the extract from banana peduncle contains high concentrations of glucose (7 g l^(-1)) , sucrose (3 g l^(-1)) and fructose (8 g l^(-1)). Fermentation of concentrated peduncle extract (5x) resulted in an ethanol yield of 41% g ethanol/ g sugars. These results are promising indications on the usability of peduncle for fermentation. In addition, all parts of the peduncle including the remaining fiber after juice extraction, banana peduncle juice and the stillage (after distillation), were successful used as feedstock for anaerobic digestion. Herein, the methane yield were 0.263, 0.043, 0.034L CH4 at STP g VS-1, respectively, showing that especially the peduncle fiber could serve as a rich feedstock for biogasification. For large scale ethanol production from peduncle juice and biogas synthesis from peduncle fiber, helping to meet the growing demand of biofuels and energy consumption in countries where banana is a principal crop.
