Investigation of the energy (biogas) production from co-digestion of organic waste materials
Biogas production rate was investigated from the co-digestion of 39 kg each of food waste, cow dung and water; 39 kg each of food waste, poultry droppings and water as well as 39 kg each of food waste, fruit waste and water in 43 litres plastic digester setup. Although organic waste mix ratios with...
