Enzymes in the bioconversion of food waste into valuable bioproducts: A circular economy perspective

Abstract

The escalating global challenges of food security, waste management, and environmental sustainability have necessitated the application of novel green approaches to utilize agro-industrial food waste as a valuable bioresource. Enzymatic conversion of food waste into high-value bioproducts emerges as one of the promising solutions to address these issues. The current review explores the critical role of enzymes in facilitating the conversion of diverse agro-industrial residues, including those from plants and animals, into biochemicals and functional ingredients. The current review evaluates the environmental and economic benefits of enzyme-mediated bioconversion processes, underlining the circular economy paradigm, which prioritizes resource efficiency and waste minimization. The enzyme production from diverse plant and animal-based food wastes as raw materials has been highlighted beside the description of different bioproducts from food waste using enzymes and the integration of enzymatic bioprocessing. The economic analysis and case studies of the enzyme-mediated processes for biochemical production from food waste have also been emphasized. By harnessing the synergistic potential of enzymes and circular economy principles, the bioconversion of agro-industrial food waste into novel bioproducts presents a viable pathway toward sustainable resource utilization and a circular bioeconomy.
