  ABSTRACT: This paper investigates the optimal conditions for methanisation applied to cow dung. Four experimental 25 liters digesters were used in this work. The best biogas yield is obtained when the digester is installed in a metal box and exposed to sunlight. The temperature in this digester varied between 25˚C and 37˚C. The dry matter content of the collected cow dung was 15.5%. The digester was fed with 9 kg of cow dung mixed with 8.5 litres of water, one litre of cassava effluent and 200 ml of human urine. After a retention period of 22 days, the biogas obtained was 67% methane and 21% carbon dioxide. The use of human urine and cassava effluent improved the quality of the biogas.
