Rapid urbanization and population increase has brought about uncontrolled landfill areas with various risks. Waste disposal to wild landfill areas has become unsustainable due to its adverse impacts such as the bad odour and appearance, infectious diseases, risk of explosion, greenhouse gases emitted into the atmosphere and contamination of natural resources. The rehabilitation activities of ITC like terracing, collection and disposal of the leachate water and landfill gas, eliminate the risk of explosion and undesired odour at landfill sites, and help disposal of the uncontrollably emanated gases and leachate water without damaging the environment.

Consequently, rehabilitation of landfill areas provides opportunity for the development of business districts and settlements in the neighborhood. The gases emitted in the landfill areas are collected with horizontal and vertical piping systems and are transformed into electrical energy in gas engines. Thereby, the greenhouse effect caused by methane, which is 21 times more dangerous than carbon dioxide, is prevented. With the progress in the rehabilitation works and disposal of the accumulated methane gas the production capacity reached 22.6 MW in Mamak Ankara by January 2009. The power plant in Mamak Landfill has become one of the highest capacity plants in a single landfill among similar applications in the world. Capacity raising studies are still ongoing. Furthermore, the capacity of the power plant in Adana
Sofulu Landfill is planned to be 10 MW.
