Paper mill sludge is the organic waste obtained from the waste water treatment of paper and pulp industries. It mainly contains cellulosic fibres, which is dumped in road sides without any use. The aim of this present study is to analyze the potential of energy generation from paper mill sludge through anaerobic digestion process and to find the optimum percentage of paper mill sludge for replacing cow dung during anaerobic digestion process. It not only generates energy in the form of biogas but also reduces environmental pollution through dumping of waste sludge. The paper mill sludge was collected from nearby paper mill and laboratory experiments using 5l Hofkins flask and field experiment in 2 m3 KVIC biogas plant was conducted to identify the biogas production from paper mill sludge. The gas production for various percentage of paper mill sludge during laboratory experiments ranged from 88.78 litre/kg of dry matter to 179.27 litre/kg of dry matter whereas in control the range is 147.01 litre/kg of dry matter to 171.39 litre/kg of dry matter. The maximum gas production was recorded in 50% and 55% paper mill sludge substitution in laboratory study using bottling experiments. In case of field experiments, the maximum gas production of 206.08 litre/kg dry matter was observed in 60% paper mill sludge substitution compared to201.34 litre/kg dry matter in control.
