Each cell represents a significant investment at about 1 million dollars and can last, depending on configuration, up to 3 years. This is the big difference between the old style “dumps” releasing leachate directly into the environment and a modern landfill.
This engineered space is maximized by staff using heavy equipment such as the Cat D6 and the Caterpillar 826 Landfill Compactor. The waste is formed into layers or lifts and then covered to ward off vectors such as bears and coyotes.
Landfill gas, consisting predominately of methane, is created as a by product of the decaying process of waste under anaerobic conditions.
