Fruit Bio-Waste Derived Bio-Ethanol Production and Bioelectricity Generation as Renewable Energy

Bio-waste from food industry is a significant component to pollute the environment. Bioproducts like biomaterials, biofuel can be produced biowaste and pollution reduced. The study was conducted evaluate quality of bioethanol production investigate for bioelectricity generation using rambutan fruit biowaste. Bioethanol yield highest in 2 days incubation period fermentation. found at 30°C having pH 5.0 compared 28 35°C. With enzymatic hydrolysis, yeast exhibited more effective as compare amylase cellulose producing bioethanol. However, glucose content lowest period. In addition, viscosity acid value were well followed by ASTM standards. Similarly, metal element contents (P, Ca, Si, Fe, Cu Pb) satisfactory within limit Pb showed zero which good energy generation. Bioelectricity represented Voltage (mV) monitored fuel cell (269.23 233.84 mV) 100% ethanol rotation fan observed 510 450 RPM decreased while time increased based cell. Therefore, it results that where conversion rate 97.2% optimized 5.0, 4g/l concentration voltage generated successfully an innovative technology field renewable energy.
