Özet

In Istanbul, the biggest city in Turkey, a large amount of solid waste is produced by the population. The bio-degradation of these wastes deposited in regular areas lead to the evolution of landfill gases. They carry a high risk of explosion and flammability, so it is of great importance to safely remove them from solid waste landfill, or as a second alternative, to find a utility for them. In this study, the major landfill gas emissions produced in Istanbul Kernerburgaz-Odayeri solid waste landfill were investigated. In the area, CH4, CO2, and O-2 measurements were made for one year, including the monitoring of all seasonal variations. In these measurements, it was determined that methane varied from 0.2-60%, while carbon dioxide showed 0.540% change, and oxygen was found to be within 0.1-19.3%. In addition, it was found for methane that 37.5% portion of the results obtained was within 5-15% (explosion interval), while 46.25% showed higher concentrations than its flaming threshold, i.e., 15%. It will have a positive effect to conveniently remove the gases in Kemerburgaz region solid waste landfill site, in terms of reduction of global greenhouse effect and explosion risk, as well as preventing these gases to reach polluting, concentrations.
