Recovery of Sustainable Renewable Energy from Marine Biomass

초록

Marine biomass is considered an important substrate for anaerobic digestion to recovery energy i.e. methane. Nevertheless, marine biomass has attracted little attention by researchers compared to terrestrial feedstock for anaerobic digestion. In this study, biochemical methane potential (BMP) test was used to evaluate generation of renewable energy from starfish. A cumulative biogas yield of 7487 mL g-1 VS-1 was obtained after 60days of digestion. The cumulative methane yield of 4868 mL CH4 g-1 VS-1 was obtained after 60 days of digestion. The methane content of the biogas was approximately 70%. The calculated data applying the modified Gompertz equation for the cumulative CH4 production showed good correlation with the experimental result obtained from this batch study. Since the result obtained from this study is comparable to results with other substrates, marine biomass can be co-digested with food waste or swine wastewater to produce CH4 gas that will help to reduce the gap in global energy demand.
