As the waste mass decomposes, the fill material settles under its own weight to occupy less volume. This process is known as '''settlement'''.<br> | As the waste mass decomposes, the fill material settles under its own weight to occupy less volume.

Settlement in landfilled waste occurs due to loading and other processes including chemical and microbial actions. These processes appear as time-dependent, and are controlled by factors such as leachate composition, pH, temperature and moisture (both as a reactant and as a vector for species transport). As a result, settlement in landfilled waste, especially long-term settlement, is complex and difficult to predict in both magnitude and timing. | Settlement in landfilled waste occurs due to loading and other processes including chemical and microbial actions.
