Biohydrogen production by anaerobic digestion of food wastes

The paper presents the results of an extensive literature review on biohydrogen production by anaerobic digestion of food wastes. Although the existing lab scale research findings have demonstrated the feasibility of hydrogen production by anaerobic digestion of food wastes. A costly and complicated system is required to produce biohydrogen by anaerobic digestion; the digester performance will likely to be unstable some times because of many interacting controlling factors. More research should be performed to develop highly effective bacteria strains, digestion conditions (temperature, pH, residence time, organic loading, ORP, alkalinity, metal ions), metabolic pathway analysis, bioreactor innovation and modeling to provide a solid foundation for large scale production of biohydrogen by anaerobic digestion of food waste in the future.
