    Abstract

    Leachate recirculation has been shown in lysimeter, pilot-scale and full-scale investigations to reduce the time required for waste stabilization, improve leachate quality, provide the opportunity for leachate volume reduction, and to enhance the rate of gas production. New generation full-scale landfills are implementing recirculation as a leachate management tool with increasing frequency. Leachate recirculation techniques used at full-scale landfills include pre-wetting of waste, leachate spraying, surface ponds, vertical injection wells and horizontal introduction systems. From observations of operating full-scale recirculating landfills, it appears to be important to provide flexibility in design, minimize low permeability daily and intermediate cover, include adequate ex situ storage volume, control infiltration into the landfill, and utilize waste moisture holding capacity efficiently.
