Abstract
So as not to pose any adverse environmental impact, landfill requires long-term management until the waste is considered stabilized. Consequently, maintenance costs increase as the period of time needed to manage the landfill lengthens. As the landfill stage is situated at the end of the waste management process, the performance of a landfill is influenced by all other waste management options. In order to shorten the landfill-care period, therefore, all waste treatment processes including source separation methods, should be considered pre-treatment steps leading up to landfilling. Key factors of waste stabilization are organic content of waste as well as the moisture and oxygen levels in the landfill. Construction and operation of the landfill should be appropriately selected based on characteristics of the specific waste.
