Biomass derived biofuel is a reducing component of global warming and greenhouse gas emission as well as reducing agent of climate change. It is biodegradable, nontoxic and environmentally friendly fuel. Bioethanol is widely used as liquid biofuel and is produced as a result of bioprocess from sugars, starches or cellulosie biomass including agro waste. The study was designed to utilize the rotten fruits of apple, mango, banana and pineapple. Fruits waste were used to produce bioethanol to contribute for clean environment by conversion of fruit waste to fuel supply and reduction of environmental pollution. The produced bioethanol was also subjected to the detailed chemical analysis (Ie, Pb, Cu, Na, Mg, Ca, etc) of residual metals. The bioethanol obtained as a result of fermentation was subjected to engine emission test and revealed a remarkable reduction of hazardous gases (NOx, SOx, HC, CO2 and CO) in the blends of bioethanol (E10, E5). The emission test was performed using a car engine (Multicylinder). It is recommended that bioethanol can be produced from waste and made industrialization using agro-waste to meet the challange of fuel crisis and environmental pollution.
