ABSTRACT

ABSTRACT: European and Italian regulations envisage a Municipal Solid Waste management system that imposes material and energy recovery prior to landfilling. Furthermore, the reduction of biowaste for landfill disposal is also rescribed. As a result, Mechanical and Biological Treatments are considered a necessary option in the waste-to-landfill path in order to reduce; the organic fraction, the biodegradability of the waste, the strength of leachate generated, the amount of biogas produced during anaerobic digestion, and the amount of settlement of the waste. This paper discusses and investigates alternative pretreatment processes, characteristics of Mechanical and Biological treatment products, mass balance, geotechnical and hydraulic behaviour of pretreated waste landfill, operational aspects.
