Food waste has become a global concern due to population growth and economic development. The wastewater from food industries contains valuable and toxic components that negatively impact the ecosystem. The review highlights the potential of food industry wastewater as a rich energy source and primary source for valuable product generation. It provides a detailed analysis of the characteristics, composition, and nature of wastewater from various food sectors.
Food waste have become a growing concern worldwide with raising population and economic growth. Waste-water discharged from food industries contains many valuable and toxic components that have a negative impact on the ecological system. Large amounts of wastewater are discharged from the food industry, which necessitates the creation of effective technologies. Wastewater from the food industry can be seen as a rich source of energy and a primary source for generating valuable products. Waste disposal and resource recovery are sustainably valued by anaerobic digestion of wastewater from the food sector. The characteristics, composition, and nature of wastewater produced from various food sectors are elaborated upon in this review. An overview of the anaerobic digestion process for wastewater treatment in the food industry is included. Enhancement strategies for the anaerobic digestion process have been discussed in detail. In addition, various types of reactors utilized for performing anaerobic digestion is illustrated. Though anaerobic digestion process possesses advantages, the challenges and future scope are examined for improving the outcome.
