Abstract
Ever since global warming, largely caused by consumption of fossil fuels, has alarmed
the scientists and policy makers, biomass has been gaining acceptance and currency as
a means of sustainable energy generation. Biogas generation through anaerobic
digestion of biomass is a promising technique of converting carbonaceous material into
methane and carbon dioxide i.e major components of biogas. This work aims at
determination of methane production rate based on kinetic study while taking into
consideration temperature, total solids, volatile solids, residence time, and bacterial
growth. We used banana waste including stem, fruit stem, peel and leaves as waste
material and applied Chen & Hashimoto kinetic model to measure the methane
potential. The wet anaerobic digestion process digested the banana waste inside the
bioreactor for 15 days of hydraulic retention time on mesophilic temperature regime
35-40°C and 10 days for thermophilic temperature regime 55-60°C. The methane
production was 14.6 m3
/day using 100 kg/day of banana waste. This showed a close
accord to the already observed and published data based on total solid, volatile solid,
carbon to nitrogen ratio and temperature.
