63.2 Landfill
63.2.1 Climate Change Impacts
Section 63.2.1.1 discusses landfill gas generation (related to the carbon content of
the waste) and its capture. This is considered for the landfilling of untreated wastes
and those that have been subject to pre-treatment such as occurs in an MBT facility.
Assumptions regarding landfill gas management are summarised in Section 63.2.1.6
which also includes a summary of the external costs associated with the climate
change impacts of landfill.
63.2.1.1 Landfill Gas Generation
In order to capture the relationship between degradation and residence time, our
model links the nature of the constituent organic compounds to the release of
greenhouse gases through time-dependent ‘first order decay’ functions (as is done in
