enough potential to setup biogas plants based on energy crops without
affecting European food supply (Smyth and Murphy, 2011).
These limitations influence the local availability of suitable feedstocks and
thus feedstock logistics and biogas plant location.
2.4.1 Organizing biomass logistics
The logistics of biogas feedstock and digestate are determined by the
feedstock types used in the biogas plant. The characteristics of the feedstock
and the digested effluent (digestate) related to energy content, density, state
of aggregation (liquid/solid), seasonality and hygienic aspects determine the
logistical concept and auxiliary components of the biogas plant such as
distance between feedstock source and biogas plant
.
distance between biogas plant and digestate use
.
suitability of road access

storage facilities for feedstock and digestate

The distance between the feedstock source and the biogas plant should be
as short as possible. Long transport distances and associated transport costs
have negative impacts on the economics of biogas plants. The literature
indicates that, due to low energy content per volume transported, it is not
