  • Landfill aeration for emission control before and during

    Dec 01, 20151. Introduction. Landfill conditioning by means of in situ aeration can be necessary for waste pre-treatment prior to landfill mining (LFM), in order to reduce the effects connected to biogas uncontrolled emissions from the waste mass during the excavation (Cossu et al., 2003a).Among the first examples of LFM in Europe, the case of Burghof landfill in Germany (Rettenberger, 1995) involved the
