Mechanism of H2S removal during landfill stabilization in waste biocover soil, an alterative landfill cover

► Capacity of H2S removal by waste biocover soil (WBS) during landfill stabilization. ► The input of landfill gas (LFG) stimulates microbial growth in the WBS cover. ► LFG induces a more rapid biotransformation between sulfide and sulfate in the WBS. ► Mechanism of H2S removal in the soils includes adsorption and biotransformation.
