Integrated Biological Treatment and Biogas Production in a Small‐Scale Slaughterhouse in Rural Ghana
A small‐scale anaerobic slaughter waste treatment plant in rural Ghana was tested for the production of energy and a microbiologically clean effluent suitable for use in irrigation. A typical day's slaughter, comprising 4 cattle, 12 sheep, and 12 goats, produced 8.5 m3 of biogas. Annually, this is equivalent to the energy from 17 metric tons of fuel wood, which is the annual productivity of 2 ha of savanna vegetation. Fecal indicator bacteria were reduced by 2 to 3 logs, nitrates by 86 to 90%, phosphates by 23%, biochemical oxygen demand by 42 to 92%, and suspended solids and dissolved solids by 73 to 86% and 19 to 37%, respectively. The effluent is used for irrigation, and the organic biomass from the digester is used as a biofertilizer. Besides energy and a cleaner effluent, the community benefited from a lessening dependency on fuel wood and reductions in unpleasant smells and nuisance animals, such as flies, dogs, and vultures.
