| Popis: | This study aimed at assessing the biogas production potential from municipal organic wastes and conver sion of biogas to electric energy for Dhaka, Bangladesh. The generati on of solid waste and demand for energy is increasi ng simultaneously in Dhaka city due to the rapid growth of population an d industrialization. As a source of renewable energ y using of municipal organic waste should be encouraged to save the envi ronment from harmful GHG as well as to minimize the energy deficiency. Among the various biogas production technologies, a naerobic digestion is one of the promising and envi ronmental friendly technology for treating organic waste. In Dhaka cit y, there are huge potential to produce biogas from municipal waste because the volume of solid waste of this city is 4000-5000 ton/day with composition of ae percentage organic w aste. Bio-waste (food waste) was used as feedstock for anaerobic digestio n process. Two inoculums-sewage sludge and digested maize silage were used with organic waste. About 0.57 m 3 /kg ODM of biogas and 0.22 m 3 /kg ODM methane was produce from the anaerobic digestion (AD) of a mixture of bio waste and digested maize sConsequently, 0.094 m 3 /kg ODM of biogas and 0.043 m 3 /kg ODM methane was generated from the fermentation of bio waste wi th sewage sludge. Biogas-to-electricity potential w as found to be 83.66 MW based on the lower value of 0.094 m 3 /kg ODM volume biogas produced, which accounts for about 3of the present demand of |
