Abstract
Leachate produced at the Zoreda landfill in Asturias, Spain, was recirculated
through a simulated landfill pilot plant. Prior to recirculation in said plant, three
loads of different amounts of MSW were added at different stages, thus forming
consecutive layers. Up until the present moment, approximately 3,333,000 Tm of
MSW have been deposited in the landfill in 2.5 m-high layers which are covered
with soil from the surrounding area and with slag from a nearby steelworks. The
organic load of the recirculated leachate decreased rapidly from initial values of
around 5,000 mg (Vl to stable values of around 1,300 mg/1. Similar values were
also found when other biological treatments were employed, i
