Food Industry Wastewater: An Efficient Bioorganic Substrate to Produce Energy-Rich Microbial Fuel Cells

초록

The food industry produces large volumes of organic-rich wastewater, representing both a waste management challenge and an opportunity for sustainable energy production. Microbial fuel cells (MFCs) have emerged as a promising technology to convert the organic components of food industry wastewater into electricity through microbial activity and harness their energy potential. This chapter describes food industry wastewater as a bioorganic substrate in MFCs, focusing on its composition, energy potential, and suitability for microbial degradation. The chapter outlines the fundamental principles of MFC operation, including the role of electroactive bacteria, electron-transfer mechanisms, and system configuration. It also discusses factors that affect MFC performance, including substrate concentration, pH, temperature, and electrode materials. Recent advances in MFC technology have been discussed, including genetically modified microorganisms and novel electrode designs that demonstrate the potential for enhanced energy recovery. Furthermore, the environmental and economic benefits of integrating MFCs into food-industry wastewater treatment processes, including reduced energy consumption and greenhouse gas emissions, are highlighted. Issues such as scalability, costs, and system optimization are discussed, as well as future research directions to overcome these barriers. By providing a comprehensive overview of this innovative approach, this chapter aims to stimulate further research and implementation of MFC technology for sustainable energy production and wastewater management in the food industry.
