  • System and method for accelerated waste decomposition in an unsecured landfill
    Patent number: 11591242
    Abstract: A system for decomposing a waste material in an unlined landfill including a landfill site having at least one waste disposal zone for receiving the waste material. The system also includes a remediation system configured for extracting a mixture of leachate and groundwater from groundwater within or adjacent to the landfill site and feeding the mixture into the at least one waste disposal zone along with air and other nutrients to enhance a rate of decay of the waste material within the at least one waste disposal zone.
    Type: Grant

  • Aerobic landfill bioreactor
    Patent number: 6364572
    Abstract: The present invention includes a system of decomposing municipal solid waste (MSW) within a landfill by converting the landfill to aerobic degradation in the following manner: (1) injecting air via the landfill leachate collection system (2) injecting air via vertical air injection wells installed within the waste mass; (3) applying leachate to the waste mass using a pressurized drip irrigation system; (4) allowing landfill gases to vent; and (5) adjusting air injection and recirculated leachate to achieve a 40% to 60% moisture level and a temperature between 120° F. and 140° F. in steady state.
