39 Digestate emissions—aerobic treatment

(1) This section applies to the following digestate treatment types:

(a) treatment in uncovered non-aerated static piles;

(b) treatment at an undocumented facility;

(c) treatment in aerated systems (turned windrows or aerated static piles);

(d) treatment at a centralised composting facility;

(e) treatment in an enclosed system (in-vessel) using a bio-filter or biogas scrubber.

(2) The emissions from the treatment of the digestate from project treatment facility t using treatment type n, EDig,t,Aer,n (in tonnes CO2-e), is worked out using the formula (equation 18):

EDig,t,Aer,n means the emissions from the treatment of the digestate from project treatment facility t, using treatment type n, in tonnes CO2-e.

QDig,t,n means the wet weight of digestate from project treatment facility t treated using treatment type n, in tonnes, worked out in accordance with the monitoring requirements.

EFDig,n means the emissions factor for treatment type n, in tonnes CO2-e per tonne of wet weight digestate, set out in the following table.
