simple landfill gas flaring, and the chance to save conventional fuels being a renewable
source of energy.
The same selected model was, then, applied to another case-study landfill in order to
investigate a management option to enhance energy recovery, consisting in leachate
recirculation. The landfill gas production and energy recovery for the conventional landfill
and the landfill with leachate recirculation were compared from different points of view:
economic evaluation, energy conversion and environmental impact. The economic analysis
showed that the specific disposal cost is lower for the landfill with leachate recirculation with
respect to the conventional landfill. Moreover, the landfill with leachate recirculation shows
better indicator values both for the overall energy conversion efficiency and for Greenhouse
Effect specific emission.
