| Summary: | Biogas is an economical and environmental friendly renewable energy which can be produced by anaerobic
digestion (AD). This biochemical method convert organic compounds (mainly from wastes) into a sustainable
source of energy. Anaerobic co-digestion (AcoD) is a method combining more than one substrates to resolve
the difficulties faced in a single substrate AD system. Solid wastes increases as the population increase so do
the urbanization and industrial industries. Food waste and sewage sludge are the examples of one of the solid
wastes. Co-digesting of both substrates may improve process stabilization to increase biogas production and
overcome the nutrients imbalance. Thus, anaerobic co-digestion has been recognized as a technology that could
provide a clean renewable energy source and helps reduce the landfill problem. This objective of this paper is
to investigate the recent achievements and perspectives on interaction of co-digestion between food waste and
sewage sludge to improve biogas production. This may provide valuable information on the optimization of
combinations of substrates: food waste and sewage sludge and prediction of bioreactor performance. |
