Lipid was extracted from dried powdered sewage sludge using a soxhlet extractor and a mixture of n–hexane and diethyl ether as extracting solvents in a ratio of 2 1. The extracted lipid was brownish black in color with a pungent smell. The physical parameters showed percentage yield of 0.58 , density of 0.875 g ml, specific gravity of 0.875 and pH of 8.5 while the chemical parameters revealed an acid value of 2.82 NaOH g, a free fatty acid of 1.41 and a saponification value of 120.615. The extracted lipid was used in the production of biodiesel by a base transesterification process. The result showed a percentage yield of 14.37 , a density of 0.854 g ml, an acid value of 0.00, a specific gravity of 0.854 and a pH of 8.5. This showed that the feedstock primary sewage sludge would be a promising source for the production of biodiesel.
