The current practices of containing the waste in dumpsite/landfill are considered as unsustainable due to their negative impact on the environment, society and economy. Remediation of the existing open dumpsite into bioreactor landfills helps in recovering the valuable land area at a faster rate due to the reduction in the time required for waste stabilization process. The problem of leachate treatment can also be addressed effectively during the remediation process. Therefore, remediating an existing dumpsite can be classified as an approach towards achieving the sustainability in landfilling practices. In this study, an approach for remediating an existing municipal solid waste (MSW) dumpsite in Bangalore city is presented by addressing the three major aspects, viz., landfill gas (LFG), leachate and the recovery of air space. Modelling tools are used to estimate the LFG emission and to design the leachate collection and recirculation systems. The methane oxidation potential of the digested MBT waste as a biocover material is evaluated using column experiments. The biocover systems are then designed to mitigate the LFG emissions from the dumpsite. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
