Biogas Production from Fruit Peel Wastes using Ultrasonic Pretreatment

EasyChair Preprint 3508

Abstract

Fruit peel wastes as a lignocellulose material which are a good feedstock for biogas production. However, hydrolysis of lignocellulose material is the rate limiting step in anaerobic digestion. The aim of this the research was to study the effect of ultrasonic pretreatment on biogas production from fruit peels. The effect of ultrasonic times (10, 20, and 30 min) and amplitudes (50, 70, and 100%) at 20 kHz were investigated for pretreatment of fruit peels. Anaerobic digestion was performed at 35 °C in 1 L laboratory glass bottle as the digester. The results showed that ultrasonic times and amplitudes could affect biogas production. The highest cumulative biogas and methane yields after 15 days for digestion were obtained from ultrasonic pretreated fruit peels at 100 % amplitude, 10 min. It were higher than the control (unpretreated fruit peels) as 34.25% and 36.92%, respectively. The ultrasonic pretreatment was able to be a potential method for biogas production that increased the amount of biogas with shorter digestion time.
