Slaughterhouse Waste Management with Biogas Technology

With rapid population growth, the demand for meat, a primary source of protein, is ever-increasing in Bangladesh. Hundreds of formal and informal slaughterhouses are attempting to provide the supply, but in a largely haphazard manner. Through a series of steps (such as receiving and resting livestock, slaughtering, removing skin, dressing of animal, removal and cleaning of stomach content and unwanted flesh and fats, transporting of processed materials etc), slaughterhouses produce large amounts solid and liquid waste. Direct disposal of highly polluted wastewater and organic residues into the drains, low lands or sewerage system without prior treatment results in environmental and ecological problems and threaten clogging the wastewater drainage systems.

Producing biogas from slaughterhouse waste could potentially be an environment friendly solution to this issue. This will result in two-fold benefits, not only will it reduce potential health and environment hazards caused by irresponsible dumping of the slaughterhouse waste, the produced biogas can also be used for cooking or for power generation.

In collaboration with the Local Government Engineering Department (LGED) constructed a slaughterhouse waste based biogas plant in Gazipur was constructed in 2011. A Financing Agreement was signed to implement a composite demonstration model of slaughterhouse Tongi Area of Gazipur City Corporation (GCC). The running biogas plant is supplying biogas to surrounding households at a fixed monthly fee, who are using it for cooking.
