Bioethanol Production from Waste Potatoes as a Sustainable Waste-to-energy Resource via Enzymatic Hydrolysis

[摘要] Ever increasing demand of energy and corresponding looming depletion of fossil fuels have transpired into a burning need of time to vie for alternative energy resources before the traditional energy sources are completely exhausted. Scientists are continuously working on sustainable energy production as an alternate source of energy to meet the present and future requirements. This research deals with conversion of the starch to fermentable carbon source (sugars) by fermentation through liquefaction by using yeast and alpha- amylase. The results show that the significant bioethanol production was achieved while using the parameters like temperature (30 C) pH (6) and incubation time of 84 hrs. About 90 ml of bioethanol was produced from potato intake of 800 g. Pakistan being an agricultural country is rich in potato crop and this research bodes well to open new vistas to arrest the energy shortage in this part of the world.
