In anaerobic co-digestion, organic solid wastes from industries like food, paper and pulp, slaughterhouse etc. are mixed with the organic fraction of municipal solid waste (OFMSW) to facilitate high rate of stabilization. The objective of mixing various substrates in this process is to control C:N ratio by adjusting the proportion of biodegradable substrates. The present paper explored the scope of co-digestion of OFMSW with various industrial wastes. It has been found that there is high potential and benefits of co-digestion towards smooth stabilization of industrial solid wastes. Many studies in this area have resulted in more balanced and nutrient-assorted substrate that improves the production of biogas for the composite OFMSW-industrial waste mix
