The exploration of biomass fuels encourages the reduction of world atmospheric pollution and global warming. In addition, the depletion of non-renewable energy sources such as fossil fuels induces the development of technologies to harness new and renewable energy sources. Abundance of fruit waste which poses environmental waste management challenges can be utilized in the bioethanol production. This in turn, helps produce alternative fuel and effective waste disposal system. Hence, bioethanol production from three different decaying fruits like Citrullus lanatus, Musa sapientum and Ananas comosus were studied. The sugar content of the citrus fruits was analyzed before and after fermentation using the DNS method. The result showed that there was a drastic sugar reduction after fermentation as sugar content before fermentation (Citrullus lanatus19mg/ml Musa sapientum 23.4mg/ml Ananas comosus 23.5mg/ml) became (Citrullus lanatus 0.8mg/ml Musa sapientum 1.5mg/mlAnanascomosus 1.5mg/ml) after fermentation. The production of bioethanol was higher in Ananas comosus 15% compared to Musa sapientun (14.8%) and Citrullus lanatus (10%) which was calculated using distillation method.
