A sustainable approach of turning Potato Peel Waste towards bioethanol production using Saccharomyces cerevisiae

Abstract

The combustion of fossil fuels for energy production releases greenhouse gas. This contributes to the rise in temperature of the global atmosphere. The search for renewable energy sources has increased worldwide to mitigate this problem. A lot of potato peel waste is generated worldwide from households and food industries can be processed to produce bioethanol as a renewable energy. This study was focused on converting the PPW and Damaged Potatoes collected from the faculty canteen of University of Chittagong and local market to produce bioethanol. Acid and enzyme hydrolysis were carried out to convert the starch into glucose. Determination of ethanol produced from two different samples were identified by FTIR analysis. Ethanol were obtained from enzymatic hydrolysis of PPW and Damaged Potatoes were 5.89 gL-1 (1.05%) and 7.22 gL-1 (5.90%) respectively. The study suggests that both PPW and Damaged Potatoes can be used as the substrate for bioethanol production.
