LAB SCALE TESTS BEFORE IN SITU AEROBIC STABILIZATION OF AN OLD LANDFILL

Lab scale tests in bioreactor were carried out in the framework of the characterization studies of a landfill where in situ aeration followed by landfill mining has been proposed as part of the novel waste management strategy in a region in northern Italy. The results obtained showed positive effects of the aeration on leachate quality and a significant reduction of waste putrescibility. The experiments were carried out with focus on carbon and nitrogen balance in the reactors; the data obtained provided information to be considered for full scale application.
