Assessment of biogas generation potential from slaughterhouse wastes in Dhaka city, Bangladesh

摘要

Abstract Slaughterhouse waste is a highly energy-rich waste and is an attractive material to treat through anaerobic digestion to produce biogas. Biogas could be burned to provide heating and electricity or can be converted to bio-methane to be used as fuel. It can also aid in waste management and evidently reduce the ecological and environmental hazards. In this paper, the potential of biogas generation from the slaughterhouses in Dhaka is investigated. Slaughterhouses in 21 regions in Dhaka city have been surveyed for data collection and analysis. The study estimates that approximately 7915 tons of slaughterhouse waste are generated annually from the slaughterhouses in Dhaka city which has the potential to generate 2.15 Mm3 of biogas. A case study on the biggest government registered slaughterhouse is also demonstrated regarding generating electricity.
