Landfill gas (LFG)
InDecember 2013, LMS Energy – the site LFGmanager
– confirmed that theNAWMA landfill had received
accreditation as aCarbon Farming Initiative (CFI)
project. TheCFI accreditation allows the claiming of
some carbon credits for the destruction of the LFG“over
and above that necessary by the site’s licence”.
The destruction of landfill gas through the on-site flare
increased in the 2013-14 year to 2,009,547 cubic
metres, a rise of 6 per cent on the previous year.
2013-14 airspace consumption
The annual volumetric surveymeasuring the airspace
consumed at the landfill (required as part of an annual
return to the EPA) was completed at the end of the
financial year.
The airspace consumed since the commencement of
operations is shown below. Initial estimateswere that
twomillion cubicmetres of airspacewere available,
and thiswill be verified on completion of the Stage 3
detailed design.
