Annex 3A1 First Order Decay Model

The first order decay (FOD) model introduced in Chapter 3 is the default method for calculating methane (CH4) emissions from solid waste disposal sites (SWDS). This Annex provides the supplementary information on this model mathematical basis for the FOD model (see Section 3A1.2), key issues in the model, such as the estimation of the mass of degradable organic carbon available for anaerobic decomposition at SWDS (DDOCm) (Section 3A1.2) and the delay time from disposal of waste in the SWDS till...

Choice of emission factors

This section includes a discussion of the choice of emission factors for the Tier 1 method. The Tier 2 method is based on mass balance principles and the Tier 3 method is based on plant-specific data therefore there are no default emission factors applicable to the Tier 2 and Tier 3 methods. Petrochemical production Tier 1 default feedstocks and processes Conventional steam reforming without primary reformer Ethylene Dichloride Vinyl Chloride Monomer Balanced Process for EDC production with...
