| Abstract | ||
| Biogas is one of the most important sources of renewable energy and is considered as an environment friendly energy source. The major goal of this research is to see if rice husk (Rh) waste and pomegranate peels (PP) waste are suitable for anaerobic digestion and what effect NaOH pre-treatment has on biogas generation. Rice husk and pomegranate peels were tested in anaerobic digestion under patch anaerobic conditions as separate wastes as well as blended together in equal proportions. The cumulative biogas output for the blank test (no pretreatment) was 1923 and 2526 ml, respectively using a single rice husk (Rh) and pomegranate peel (PP) substrates. The 50% rice husk digestion and 50% of pomegranate peels for blank test gave the result 2246 ml of accumulative biogas during 15 days of digestion. These findings show that Rh degradation is less appropriate for the digestion of a single substrate. Because of Rh's high lignin material. The digestion of the rice-husk-peel blend enhanced the digestibility of the rice husk and thus increased the yield of biogas. 3% NaOH chemical pretreatment are investigated in addition to blank test in order to find the effect of pretreatment on rice husk and pomegranate peels for biogas production. The pretreatment increases the accumulative biogas for Rh, PP and mixture of 50% Rh with 50% PP from 1923, 2526 and 2246 ml to 2007, 2560 and 2309 ml respectively. | ||
