Over time, trash in landfills decomposes. The rate of decomposition varies based on the material, moisture and amount of oxygen. Landfill operators try to maximize the compaction of the material in a landfill threfore reducing the available oxygen available for the decomposition process. When the trash decomposes, methane gas is released. The amount of gas has to be controlled by venting or capturing it to avoid underground fires.
