This is paper written by Haris kamariotakis and me.
It was presented and discussed at ISWA Master Class for sustainable landfills, October 2009 in Lisbon. The Master Class was organized by ISWA Working Group on Sanitary Landfills, which is chaired by ny good friend Derek Greedy.
I think its view was really appreciated by the participants.
I hope you will enjoy it too.
