recovery’ option the user can leave cells empty in the of Landfill-gas recovery ‘Specifications session. Although the sanitary landfill with gas recovery option may exist without an energy recovery system, the user can still leave the cells empty. However, landfill gas flaring may be the option in the case of energy recovery’ choice from sanitary landfill with gas recovery. ‘No Flaring would create particulate matter (PM) in the form of BC. However, currently available emissions quantification methods would not be sufficient to quantify BC emissions from landfill gas flaring and these estimations needs to be included in the future. The basic concept used in the IPCC 2006 Waste Model has been adopted in this tool to quantify CH4 emissions from different types of landfills. The guidelines of IPCC strongly encourage the use of the First Order Decay (FOD) model, which produces more accurate emissions estimates as it reflects the degradation rate of wastes in a disposal site (IPCC 2006). The model assumes that decomposition in the first year can happen aerobically where CH4 generation is not taking place. In addition, other GHGs and BC emissions will be estimated based on the fossil energy and grid electricity consumption for operational activities. The step-by-step procedure for calculation of GHG/SLCP emissions from landfill/open dump technologies is shown in Box 7. Box 7: Method of estimating GHG/SLCP emissions from landfilling/open dumping
