Abstract: The effect of seeding of wood-ash using pig waste and cassava peels in laboratory anaerobic digester on the production of biogas was investigated. Pig waste and cassava peels were mixed in varying concentrations and left for anaerobic digestion in sterile distilled water for a period of 45 days. One of the digesters was seeded with wood-ash. The volume of biogas produced ranged from 83-2345 cm3 with different concentrations of pig waste and cassava peels. The seeded digester yielded the highest volume of biogas. Sole digestion of pig waste and cassava peels yielded 430 and 83 cm3, respectively. The maceration of cassava peels resulted to an increase of acidity of medium such that biogas production was extremely reduced.
