Hybrid Biofuel Systems Combining Waste Biomass and Algae: A Sustainable Approach to Renewable Energy

Abstract

The increasing demand for sustainable energy sources has intensified research on biofuels derived from alternative feedstocks. Hybrid biofuel systems, which integrate waste biomass and microalgae, present a promising strategy to overcome feedstock limitations while enhancing energy yield and environmental sustainability. This paper reviews recent advances in co-processing techniques, algal strain selection, metabolic engineering, and reactor design. It explores the potential of hybrid systems to produce bioethanol, biodiesel, and biogas efficiently while reducing reliance on food-based feedstocks. Challenges in large-scale implementation, nutrient management, and process optimization are discussed. Case studies demonstrate improvements in energy output, carbon sequestration, and waste valorization, highlighting hybrid biofuel systems as a critical component of a circular, low-carbon energy economy.
