It is the conversion and control process of landfill gas , occurring in landfills , 52 % of which is formed by ‘methane’, with a ‘greenhouse’ effect of 20 times as much as carbon dioxide, into electricity power. The household waste in Solid Waste Landfill decomposes aerobically. Creating a vacuum environment by covering the area, the formation of methane gas is commenced as a result of the emergent decomposition. Landfill gas (LFG), which is taken with a certain vacuum from the wells drilled in an average depth of 28 m, is transmitted to the structures called gas collector (manifold) with separate lines. There are approximately 8-12 wells in each manifold. The leachate in the landfill is accumulated in condensate tanks, and then pumped to the biological wastewater treatment plant.
The disposal and control of landfills are of great importance for both its damage to the environment and its risk of explosion due to the high proportion of methane it includes. In this regard, the Ministry of Environment and Urbanization has identified various laws for environmentally sensitive waste disposal. Landfill gas offers the most accurate and effective solution for municipalities both in terms of eliminating these negative factors and complying with the law.
