For estimation of landfill gas generation, IPCC(Intergovernmental Panel on Climate Change) recommended using FOD model that is based on First Oder Decay equation and presented a default value for parameters. Especially a default value for DOCf(Fraction of Degradable Organic Carbon which decomposes) have problems that is not based on experimental data, and is not considered for loss with leachate. The objective of this study is to estimate DOCf about A landfill which have a waste composition data and the biodegradability data through BMP (Biochemical Methane Potential) test. Also DOCf loss in leachate calculated by Carbon Flow Analysis about A, B landfill. As a result, DOCf is a range of 0.58 to 0.62 from 1992 to 2000 and this values are higher than IPCC default value(0.5). From Carbon Flow Analysis, 40.11% of total disposed carbon is emitted by gaseous carbon(CH4) and 0.29% lost with leachate in A landfill. In case of B landfill, 36.92% of total disposed carbon is emitted by gaseous carbon and 0.30% of carbon lost with leachate. Therefore carbon loss through leachate is less than 1% and this may be neglected for estimation of DOCf.
