EFFECT OF TEMPERATURE ON BIOGAS PRODUCTION POTENTIAL OF BANANA PEELS CO DIGESTED WITH BIOGAS SLURRY IN ANAEROBIC BIOREACTOR

Abstract

Due to increase in demand our conventional resources are insufficient to fulfill the world energy demand. Renewable techniques are extremely economical due to converting useless waste into energy. To achieve that purpose anaerobic digestion was performed on banana peels with co digested with biogas slurry. Input feedstock to anaerobic plant was banana peels which already passed through four pretreatments such as, glycerol, sodium hydroxide, calcium hydroxide and acetic acid at variable conditions. Glycerol treatment give most efficient results due to more removal of lignin up to 87%. Anaerobic digestion is completely environmental friendly with no carbon dioxide emission and due to benefits it can adopted more in future on industrial and domestic scale. 6 liter capacity tank was installed at 4 liter with 10% TS level to giving space at top for biogas production. Trails was performed at two temperature 37°C and 55°C but more biogas produced at 55 °C with retention time period of eighteen days. In slurry tank manually stirring was provided and produced gas was calculated through water displacement method. This study help to decrease city waste by installing anaerobic plants. In that way we can achieve sustainability and waste can also be controlled.
