Methane emissions from domestic waste management facilities in Jordan - Applicability of IPCC methodology

In this paper, methane emissions from municipal wastewater treatment plants and municipal solid waste (MSW) landfills in Jordan for 1994 have been est imated using the methodology developed by the Intergovernmental Panel on Cl imate Change (IPCC). For this purpose, the 14 domestic wastewater treatment plants in the country were surveyed. Generation rates and characterization of MSW components as well as dumping and landfilling practices were survey ed in order to estimate 1994 CH4 emissions from these sites. Locally availa ble waste statistics were used in cases where those of the IPCC guidelines were not representative of Jordan's statistics. Methane emissions from domestic wastewater in Jordan were estimated at 4.66 gigagrams (Gg). Total 1994 CH4 emissions from MSW management facilities in Jordan are estimated at 371.76 Gg-51.12 Gg (94.45%) from sanitary landfill s, 19.83 Gg (5.33%) from MSW open dumps, and 0.81 Gg (0.22%) from raw sewag e-water dumping ponds. Uncertainties associated with these estimations are presented.
