Food waste is one of the most pressing global challenges due to its significant environmental, economic, and social impacts. Nearly one-third of all food produced for human consumption is lost or wasted annually, contributing to greenhouse gas emissions, resource depletion, and food insecurity. This study investigates the microbial processing of food waste as a sustainable approach for transforming organic residues into renewable energy and valuable bioproducts. Various microbial and thermochemical conversion methods including anaerobic digestion, fermentation, pyrolysis, gasification, and composting are examined for their ability to produce bioenergy, biogas, bioethanol, biochar, bioplastics, single-cell proteins, and nutrient-rich compost. These technologies not only reduce the volume of waste but also enhance circular economy practices by converting waste materials into resources that support agriculture and industry. Furthermore, advances in metagenomic tools and microbial biotechnology have improved understanding of microbial communities and enhanced the efficiency and yield of bioconversion processes. Integrating these biological and engineering innovations can optimize waste valorization systems, leading to reduced greenhouse gas emissions, improved nutrient recycling, and sustainable energy generation. Overall, microbial processing offers an eco-friendly and economically viable strategy for global food waste management, aligning with the United Nations Sustainable Development Goals to reduce waste and promote renewable energy use. The outcomes of this research highlight the potential of microorganisms to convert food waste into bioenergy and bioproducts, thereby supporting environmental preservation and resource recovery.
