A comparative study on estimating the landfill gas potential: Modeling and analysis

The main objective of this study is to investigate the use of the landfill gas as potential energy and electricity obtained from the municipal solid waste (domestic, industrial, medical waste, and sewage sludge) stored regularly in the Harmandali solid waste landfill area, within the boundaries of the contiguous area of Izmir. The most important factor in making a decision about energy potential in the landfill is the amount of methane in the landfill gas. There are several approaches that have been used to determine the amount of the landfill gas. In this study, three different methods and one approach in the literature were used for this purpose. The methods used are the Multi-Phase, the LandGEM, and the IPCC 2006. The results of the landfill gas obtained using the three methods, namely the Multi-Phase, the LandGEM (k = 0.35, k = 0.1, and k = 0.05), and the IPCC 2006, were as follows, respectively: 291897215, 792073359, 769734749, 681685027, and 491752247 m3. It may be concluded that the Harmandali Landfill has high landfill gas potential based on the measurements and mathematical methods used in the Harmandali landfill.
