*5.4. Poultry Slaughterhouse Wastewater*

Disposed poultry slaughterhouse waste and effluents containing excreta from birds, feed, feathers, hatchery waste, urine, feces, sawdust, etc., were determined to be suitable to generate an engineered biofilm in the anode of an MFC. The biofilm was constituted by *Escherichia coli*, *Enterobacter*, *Citrobacter*, *Geobacter*, *Klebsiella*, *Lactobacillus*, and *Pseudomonas* spp. [114]. Using MFC with rice husk charcoal as an electrode in combination with effluent from poultry slaughterhouses generated a volumetric power output of 6.9 W/m<sup>3</sup> while achieving a 40% dissolved organic carbon reduction [115]. Similarly, an energy generation harvesting rate of 278 mW/m<sup>2</sup> was observed with an effective 82% BOD removal efficiency in a continuous horizontal flow MFC [116].
