Impact Of Full-Scale Leachate Recirculation On Leachate And Gas Characteristics

Data from full-scale recirculating landfills were analyzed and compared with data from pilot and laboratory-scale investigations, and found to support conclusions drawn from tests, ie, an acceleration of stabilization processes, leachate management opportunities, and enhancement of gas production can be expected during leachate recirculation. Leachate characteristics follow patterns observed in conventionally operated landfills, however degradation occurs at a faster rate. Leachate production rates are a function of landfill operations, climate, and recirculation rates. On-site storage is critical to leachate management and can dramatically reduce volume of leachate treated off-site
