    Definition method of estimation of CH4 from solid waste disposal in which the timing of the emissions are taken into consideration Reference "COM-EN, based on:IPCC. Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories. CH4 EMISSIONS FROM SOLID WASTEDISPOSAL http://www.ipcc-nggip.iges.or.jp/public/gp/bgp/5_1_CH4_Solid_Waste.pdf [15.2.2012]"
    Comment "For the equations, see: IPCC.2006 IPCC Guidelines for National Greenhouse Gas Inventories. Volume 5: Waste. Chapter 3. Solid Waste Disposal http://www.ipcc-nggip.iges.or.jp/public/2006gl/pdf/5_Volume5/V5_3_Ch3_SWDS.pdf [15.2.2012]This method assumes that the degradable organic component (degradable organic carbon, DOC) in waste decays slowly throughout a few decades, during which CH4 and CO2 are formed. If conditions are constant, the rate of CH4 production depends solely on the amount of carbon remaining in the waste. As a result emissions of CH4 from waste deposited in a disposal site are highest in the first few years after deposition, then gradually decline as the degradable carbon in the waste is consumed by the bacteria responsible for the decay.This method gives a more realistic picture of the actual emissions during for the inventory year in question than the the IPCC default method (a massbalance method) which does not reflect the time variation in solid waste disposaland the degradation process as it assumes that all potential methane is released the year the solid waste is disposed"

    Definition "if in a reaction between A and B, B stays constant, then the order of the reaction [ IATE:3523310 ] (with respect to time), as observed from the concentration change of A with time, will be α, and the rate of disappearance of A can be expressed in the form: vA = kobs[A]α (since the overall rate of reaction is given by: v = k[A]α[B]β). The proportionality factor kobs deduced from such an experiment is called the 'observed rate coefficient' and it is related to the ( α + β )th order rate coefficient k by the equation: kobs = k[B]β. For the common case when α = 1, kobs is often referred to as a 'pseudo-first order rate coefficient' (kψ)" Reference "IUPAC. Compendium of Chemical Terminology, 2nd ed. (the ""Gold Book"").
