In countries like India food waste accounts for more than 50% of the Municipal solid waste collected. Food waste has a lot of potential to be used as a raw material because of its enrichment in organic properties. Thisreview paper presents a study on the basic principles of anaerobic digestion and the reactions which let it occur. Here we have observed all those factors on which the efficiency and production of biogas depends such as pH, Temperature, C/N Ratio, Retention Time. We also have discussed the parameters so that some changes in the digester can be done to increase the efficiency.
