Description:
A sequential aerobic-anaerobic treatment system has been applied at a commercial scale (3,000 ton per day) municipal solid waste landfill in Kentucky, USA since 2001. In this system, the uppermost layer of landfilled waste is aerated and liquid waste including leachate, surface water, groundwater as well as beverage and food-processing wastes are added to the landfill to provide moisture. A portion of the data from the first four years of a cooperative research and development project between Waste Management, Inc. and the US EPA are summarized. Results indicate the aerobic-anaerobic system has a higher degradable solids removal and landfill gas production than an adjacent untreated landfill. The aerobic-anaerobic cells also demonstrate higher leachate temperatures.
