Executive Summary : | This study explores the potential of potato peel waste as a sustainable biomass for bioethanol production. The extraction of amylase enzymes from potato peel waste is improved, and the waste is converted into fermentable sugars using amylase. The process is enzymatically degraded using ultrasonics, a technique that enhances the hydrolysis reaction. The resulting glucose or maltose-rich solution can be used in various industries. The study also focuses on improving the fermentation process, ensuring high-purity ethanol production, and evaluating the competitiveness, sustainability, benefits, and limits of the bioethanol production method. The economic viability and cost-effectiveness of using potato peel waste as a feedstock for bioethanol production are also assessed. Ultrasonics-assisted ethanol production offers a sustainable, environmentally friendly solution for converting food industry by-products into valuable biofuels. This method enhances starch hydrolysis, enables better utilization of amylose and amylopectin, reduces enzyme consumption, and promotes faster fermentation. It also offers waste valorisation, energy efficiency, and reduces greenhouse gas emissions. This approach also reduces reliance on food-based feedstocks and offers potential for small-scale and local applications. As technology advances, this approach could play a crucial role in the bioenergy sector. |
