Biogas potential from municipal and agricultural residual biomass for power generation in Hazaribagh, Bangladesh - A strategy to improve the energy system

摘要

Energy is considered as one of the significant benchmarks towards sustainable growth. Due to the recent economic growth, energy demand is increasing day by day in Bangladesh. The power generation mainly relies on fossil fuels though there are plans to increase the renewable energy share by the concern stakeholders. Considering the global warming, energy generation from renewable sources is considered as a sustainable way to mitigate the anthropogenic emission. This study, therefore, addresses the potentiality of biogas production from municipal waste and agricultural residues in a city territory of Dhaka namely Hazaribagh. The potential sources include wastes from two markets, six slaughterhouses, domestic wastes, one poultry farm and three croplands. The calculations made in this study to estimate the amount of biogas and electricity from the described sources are done in a simple way, just to illustrate the potential. This study suggests that there is a good potentiality of biogas production and electricity generation from municipal wastes and agricultural residues of Hazaribagh. Moreover, this study also mentions the significant actors like government, future owners, people and so on that are needed to be incorporated to implement biogas solution in a city territory.
