Abstract

The excessive consumption of fossil fuel particularly in urban areas due to transportation and industrial activities has greatly contributed to generation of high levels of pollution; therefore, a renewable eco-friendly energy source is required. The production of bioethanol from sugar extracted from waste fruit peels as an energy supply is renewable as the non-fossil carbon source used is readily replenished. Laboratory experiments were conducted to evaluate the chemical composition of fruit wastes of orange and Mango in order to explore their potential application in bio-ethanol production. Experimental production of Bioethanol from waste fruits of mango and orange was carried out after dilute acid pretreatment followed by enzymatic saccharification  using saccharomyces cerevisiae for the fermentation process. Three samples of (mango waste fruit, orange waste fruit and mixture of mango and orange waste fruit) 100g each was used for the same method of bio-ethanol extraction. A one factor factorial design involving fruit type was used to statistically analyze the fuel properties of the ethanol produced from the fruits waste. Analysis of variance (ANOVA) shows that the observed difference were not significant for all the properties except that of the flash point which showed that the flash point of the produced bioethanol differ from that of the standard ethanol, which may be due to percentage of moisture present in the samples used. The highest yield of ethanol from sample A (mango waste) was 19.98%, sample B (orange waste) produced 19.17% while least yield of ethanol was from sample C (mango and orange waste) which produced 17.38%.
