This volume comprehensively explores the role of microbial-assisted bioconversion techniques in waste management, with a focus on how waste products can be utilized and repurposed towards sustainable ends. Bioconversion of environmental wastes to value-added products refers to the process of using microorganisms to transform organic waste materials like agricultural residues, food scraps, or industrial byproducts into useful and commercially valuable products, providing a sustainable approach to waste management by turning potential pollutants into beneficial resources. Microorganisms, such as bacteria and fungi, are utilized to break down complex organic molecules within the waste into simpler compounds that can be further processed into valuable products through fermentation or other biological pathways.
