Abstract

A square flux chamber was constructed to quantify and characterize methane (CH 4) and carbon dioxide (CO 2) emissions from the open dumping landfill Sungai Sedu in Malaysia during wet season. To obtain data for quantifying CH 4 and CO 2 emissions from the open dumping landfill in terms of spatial variability using point kriging and inverse distance weight (IDW) methods, intensive sampling from September to December 2010 was performed in an area overlaid with a 3.5m×3.5m grid. The geospatial means of CH 4 emissions obtained by point kriging and IDW were 10.23 and 9.44gm -2d -1, respectively; for the CO 2 emissions, the two methods resulted in values of 35.7 and 34.7gm -2d -1, respectively. The geospatial means were slightly different from the arithmetic means of 9.23 and 34.36gm -2d -1 for CH 4 and CO 2, respectively, but were 3.2 and 1.6 times higher than the geometric means, respectively. The total CH 4 and CO 2 emissions from the studied area were 21.2 and 53.7kgd -1, respectively. The total CH 4 emission estimated was modeled with the Inter-governmental Panel on Climate Change (IPCC) Waste Model in order to estimate CH 4 generation rate constant, k. The estimated value of k 0.0033y -1. Using a zero model default value of CH 4 oxidation was underestimated the k value.
