The present study aimed to produce biogas using liquid from OFMSW fermentation. In this study the physic-chemical parameters of liquid from OFMSW were determined. Anaerobic digestion using liquid from OFMSW and 2 % (w/v) of OFMSW as substrate load was carried out both in batch anaerobic digesters during 25 days. The pH, ammonium nitrogen and gas (CO2, CH4 and H2S) were followed during anaerobic digestion. The concentration of ammonium nitrogen ranged respectively 3 g NH4-N·L-1 to 6 g NH4-N·L-1 and 5 g NH4-N·L-1 to 9 g NH4-N·L-1 in anaerobic digestion from liquid from OFMSW and 2 % of OFMSW. This technology has permit to obtain good quality of biogas (57 % CH4, 3 % CO2 and 20 ppm H2S) in a short time of 20 days.
