Bananas another important source of bio energy.

Banana is one of the most important fruit crops in the world.Banana production is a tropical, herbaceous and perennial crop and belongs to the Musaceae family, which produces one huge flower cluster and then dies. The plant is cut to bring the crop down, thus the stem and leaves turn into lignocellulosic biomass. Once a bunch arrives at the packaging plant, the bunch rachis becomes residual biomass too. The ratio of banana waste and product is 2:1. The lignocellulosic biomass is either left on the ground or taken to open dumps. In the first case, the process leads to maintain the soil moisture and provide organic matter, but it is a potential risk of transmission of disease and, in both cases, the lignocellulosic biomass produce greenhouse gases as they decompose. Researchers from the Agro-Energy Group at Universidad Politécnica de Madrid (UPM) have used geographic information systems to assess the potential use of the residual biomass of bananas produced in the province of El Oro (Ecuador) for bioenergy applications. Results show that the use of this waste could satisfy the 55% of the electrical demand of the region and the 10% of bioethanol demand nationwide. In addition to lignocellulosic biomass there is another residue, that
