34  Emissions from composting processes
 (1) The emissions from composting processes used during a reporting period, in tonnes CO2‑e, are worked out using:
 (a) if enclosed composting technology used during the reporting period includes open windrow composting—sub‑method 1 (see subsection (6)); or
 (b) if enclosed composting technology used during the reporting period does not include open windrow composting—subject to subsections (2) to (5) and section 46, either:
 (i) sub‑method 1 (see subsection (6)); or
 (ii) sub‑method 2 (see subsection (7)).
Note 1: Sub‑method 1 uses default emissions factors to calculate emissions and sub‑method 2 uses direct measurement to calculate emissions.
Note 2: If, under subsection (5), sub‑method 2 must be used to calculate the emissions but the project proponent fails to monitor the parameter DMCompost,j as required by the monitoring requirements, the emissions are to be worked out in accordance with section 46 (see section 46).
 (2) If sub‑method 1 is used to work out the emissions of methane for a reporting period, that sub‑method must also be used to calculate the emissions of nitrous oxide for the reporting period.
 (3) Sub‑method 2 may only be used to work out the emissions for a reporting period if the parameter DMCompost,j is monitored as required by section 45 during the reporting period.
 (4) If sub‑method 2 is used to work out the emissions of nitrous oxide for a reporting period, that sub‑method must also be used to work out the emissions of methane for the reporting period.
 (5) If sub‑method 2 is used to work out the emissions of a greenhouse gas type (whether methane or nitrous oxide) for a reporting period, that sub‑method must be used to calculate the emissions of that greenhouse gas type for all subsequent reporting periods.

Sub‑method 1
 (6) The emissions from composting processes used during the reporting period, in tonnes CO2‑e, are worked out using the formula (equation 14):
where:
ECompost means the emissions from composting processes used during the reporting period, in tonnes CO2‑e, being methane or nitrous oxide.
QCompost means the quantity of waste composted during the reporting period, in tonnes, worked out in accordance with the monitoring requirements.
EFCompost,j means the emissions factor, in tonnes CO2‑e, mentioned in subsection 5.22(2) of the NGER (Measurement) Determination for greenhouse gas j and the composting process.
RECompost means:
 (a) if a biofilter is used to filter emissions from the composting processes before release to the atmosphere—10%; or
 (b) otherwise—0.
j means a greenhouse gas type, being methane or nitrous oxide.

Sub‑method 2
 (7) The emissions from composting processes used during the reporting period, in tonnes CO2‑e, are worked out using the formula (equation 15):
where:
ECompost means the emissions from composting processes used during the
