GRAY BOX MODELING OF MSW DEGRADATION: REVEALING ITS DOMINANT (BIO)CHEMICAL MECHANISM

摘要

Completion of landfill aftercare requires a quantitative estimate of the remaining emission potential present in the waste body. Knowing the emission potential is also relevant when implementing management scenarios aiming to stabilize the waste body (infiltration, lcachate recirculation, aeration etc.). An important part of landfill stabilization is the degradation of the available organic matter in the waste body. We hypothesize that most of the organic degradation takes place in immobile water regions or 'water pockets' within Municipal Solid Waste (MSW) landfills. A good understanding of the processes occurring within these 'water pockets' is therefore essential for accurate prediction of landfill emission behavior.
