Processes I.8 to I.10: Handling the fibre pellets from the farm to the biogas plant before biogas is produced

I. 8 Storage of the fibre pellets at the farm

As described in Annex D, section D.9, it is assumed that there are no significant emissions from the fibre pellets during storage.

Accordingly, the fibre pellets after the storage has the same composition as at the outlet of the Samson Bimatech Energy Plant (as presented in table D.1 in Annex D).

I.9 Transport of fibre pellets to biogas plant

The transport of the fibre pellets to the biogas plant in this Annex is identical to the transport of the fibre fraction in Annex F, see section F.9 (i.e. the same distance, but different amount).

I.10 Storage of the fibre pellets at the biogas plant

The storage of the fibre pellets at the biogas plant is based on the same assumptions as the storage of the fibre fraction at the biogas plant in Annex F, i.e. that the storage time for the fibre fraction at the biogas plant is very short – from a few days to maximum a week – and accordingly, it means that the emissions occurring during the temporal storage of the fibre fraction at the biogas plant are considered as negligible.
