Enzyme-Mediated Strategies for Effective Management and Valorization of Biomass Waste

The efficient utilization of biomass waste is crucial for sustainable growth and the transition toward a circular bioeconomy. Enzyme-mediated strategies have emerged as promising solutions for the efficient management and valorization of biomass waste. The use of enzymes allows for the breakdown of complex organic molecules, facilitating biomass waste conversion to useful products such as biofuels, bioplastics, and bio-based chemicals. This approach offers several advantages over traditional methods of biomass waste management, including a reduction in emission of greenhouse gases and a decrease in fossil fuels dependence. This chapter provides an overview of the various types of enzymes involved in the conversion of biomass waste, such as cellulases, hemicellulases, ligninases, and lipases. The mechanisms of action and substrate specificities of these enzymes and their importance in the breakdown of complex biomass structures into simpler building blocks were discussed. Various enzyme-mediated management and valorization strategies such as enzymatic hydrolysis, enzymatic pretreatment, and enzymatic conversion of lignocellulosic biomass for the synthesis of biochemicals and biofuels, the enzymatic pretreatment of agricultural residues for the production of bioplastics, and the enzymatic hydrolysis of food waste materials for the synthesis of useful chemicals were also highlighted. Finally, challenges and opportunities associated with the commercialization of enzyme-mediated biomass waste conversion technologies, the cost-effectiveness, scalability, and regulatory issues are highlighted, along with the potential of enzyme engineering and bioprocessing optimization to improve the performance and efficiency of these technologies.
