Production and Performance Evaluation of Biofuel Obtained from <i>Artocarpus heterophyllus</i> Waste

Biofuel production from agricultural and fruit wastes is one of the major solutions towards the generation of renewable energy and the management of waste. Production of low-cost second generation Biofuel from lignocellulosic fruit wastes of Artocarpus heterophyllus was carried out by saccharification and fermentation process. Baker’s yeast was used for fermentation as it gives a high yield of bioethanol. Reducing sugars in the pretreated sample at different acid concentrations was found using the DNSA Method. The process optimization was carried out by varying fermentation temperatures to obtain a high bioethanol yield. The produced bioethanol was extracted by distillation process. The bioethanol obtained was tested for its efficiency in a four-stroke single-cylinder petrol engine Test Rig. The bioethanol was blended with petrol in different proportions. The results obtained indicate the addition of bioethanol to petrol can reduce harmful combustion gases thereby contributing to decreasing pollution. It also improves brake thermal efficiencies and reduces the consumption of fuel. The fuel combustion properties and Calorific Value of the petrol bioethanol blend were also determined.
