Abstract:

It is believed and through various experimental studies, it is identified that the anaerobic digestion is one of the viable technologies to convert solid waste in to energy form Further the anaerobic digestion is developed in the way of co-digestion processes whereas in gleor various substrates added together through this co-digestion process, C/N ratio and buffering capacity is balanced for digestion. Moreover, the gas production will be increased. Hence, this study focus towards the utilization of kitchen waste, slaughterhouse waste and Poultry litter as substrate forco digestion process. The characteristics of substrates and inoculum and influent were analysed. Continuous monitoring was done to measure the gas production. Similarly, the other enhancing treatment technique modes was adopted as pre-treatment for substrates in thermal, chemical and thermochemical. The treated substrates were allowed for digestion and the gas production were observed. It is observed that the kitchen waste, slaughter house waste and poultry litter The experimental study observed the efficiency of gas production is more in pre-treated substrates. The digester without pre-treatment for 13days gas production observed 53 ml similarly for chemical treatment 210 ml for thermal treatment 70 ml and thermochemical treatment 65 ml.
