Susteinable landfill represent an innovative way of managing such waste disposal plants, able to lead both to environmental and energetic advantages. The rapidity of the anaerobic biodegradation process of the biodegradable fraction of the waste, can be improved combining aerobic with anaerobic phases. An aerobic pre-treatment of the waste ranging from 15 to 60 days, together with the leachate recirculation, can lead to the production of more than 170 Nm3 per each tonne of Volatile Solids disposed inside the landfill. The anaerobic biodegradation process takes place from 3 to 14 years, depending on some difference in landfill cultivation. Further, the global amount of renewable electrical energy recoverable ranges from 42 to 44 GWh, and the biomethane loss can be restrain to less than 39% of the global production.

Abstract
Susteinable landfill represent an innovative way of managing such waste disposal plants, able to lead both to environmental and energetic advantages. The rapidity of the anaerobic biodegradation process of the biodegradable fraction of the waste, can be improved combining aerobic with anaerobic phases. An aerobic pre-treatment of the waste ranging from 15 to 60 days, together with the leachate recirculation, can lead to the production of more than 170 Nm3 per each tonne of Volatile Solids disposed inside the landfill. The anaerobic biodegradation process takes place from 3 to 14 years, depending on some difference in landfill cultivation. Further, the global amount of renewable electrical energy recoverable ranges from 42 to 44 GWh, and the biomethane loss can be restrain to less than 39% of the global production.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
