Valorization of Biowastes for Energy Production Using Halophiles

Waste generation from various human activities, spanning domestic, industrial, agricultural, and livestock sectors poses a significant challenge. Both non-degradable elements like plastics, metals, and hazardous chemicals, as well as biodegradable waste, have exceeded natural recycling capacities. While incineration seems to be a straightforward solution, it leads to air quality deterioration. To address this, exploring alternate routes to convert biowaste into valuable resources is imperative. Leveraging the inherent energy in organic waste through biofuel production stands out as a promising solution. Among different microorganisms, halophiles, due to their diverse metabolic abilities encompassing fermentation, photolysis, and anaerobic digestion, offer a unique opportunity to convert lignocellulosic waste into bioethanol, biobutanol, biodiesel, biohydrogen, and biogas. However, their potential in biowaste transformation remains largely untapped. While biotransformation of waste to energy offers economic benefits by cutting waste disposal costs and generating valuable by-products, challenges do persist. Economic viability hinges on feedstock availability, technological efficiency, and market demand for biofuels and by-products. Overcoming these challenges necessitates meticulous planning, extensive research, and collaborative efforts to unleash the full economic potential of halophile-driven biowaste-to-energy projects.
