This research investigated the performance and greenhouse gas emission from high strength municipal solid waste (MSW) leachate by sequencing batch reactor(SBR) with Alcaligenes faecalis No.4 (A. faecalis No.4). The SBR was carried out by anaerobic reactor followed by aerobic reactor. The system was operated at hydraulic retention times (HRT) of 2 days during 130 operating days (Run 1) and 45 days with A. faecalis No.4 (Run 2). At steady state, the organic removal efficiencies were found to be 62.7% for (Run 1) and 86.7% for (Run 2). The organic carbon and nitrogen were mainly removed in aerobic reactor. The surface emission rates of methane and Nitrous oxide in aerobic reactor were reduced 35% and 14%, respectively with A. faecalis No.4
