32 Emissions from post-diversion treatment of material diverted in emissions avoidance: conversion abatement
Methane emissions
(1) The emissions due to methane arising from the post-diversion treatment of material diverted in project treatment facility h under a treatment method during a reporting period, EPost, Methane (in tonnes CO2‑e) is worked out using the formula:
| | Equation 12 |
γ is the factor, used in Part 5.3 of the NGER (Measurement) Determination, that converts cubic metres of methane to tonnes CO2‑e at standard conditions.
n is a treatment method.
MCFPost, n is the post-diversion methane conversion factor for treatment method n, that is:
(a) specified in the Supplement; and
(b) if a project treatment facility uses more than one post-diversion treatment at a facility—is the highest applicable post-diversion methane conversion factor.
Note: This factor, which is a proportion less than 1, represents the amount of methane produced by the diverted material under the relevant treatment method as a proportion of its methane-producing capacity.
w is a type of material that includes volatile solids.
VSDiv, w, n is the amount of volatile solids from material of type w that is diverted in the project treatment facility during the reporting period, and treated using treatment method n, in tonnes of volatile solids, determined in accordance with the Supplement.
Bo,Div, w is the methane-producing capacity for the volatile solids of material of type w, in cubic metres of methane per tonne of volatile solids, determined in accordance with the Supplement, subject to subsection (3).
Nitrogen related emissions
(2) The emissions due to nitrogen arising from the post-diversion treatment of material diverted in project treatment facility h under a treatment method during the reporting period, EPost, Nitrogen, (in tonnes CO2‑e) is worked out using the formula:
| | Equation 13 |
N2O-NCF, the nitrous oxide conversion factor, converts tonnes of N2O-N into tonnes CO2-e, specified in the Supplement.
n is a treatment method.
INOEFPost, n, the post-diversion integrated nitrous oxide emission factor for treatment type n, specified in the Supplement.
Note: This factor reflects the amount of nitrous oxide produced by diverted material using the relevant treatment method.
w is a type of material from which volatile solids are taken.
NDiv, w, n is the amount of nitrogen in the material of type w that is diverted in the project treatment facility during the reporting period, and treated using treatment method n, in tonnes of nitrogen, determined in accordance with the Supplement.
