The biomass of giant reed (Arundo donax L.) may found different
applications in energy production. The handling of a
variable feedstock (partially dried from resting plants or green
from plants actively growing) calls for a identification of the
most suitable storage method.
The aim of the study was to investigate alternative storage
systems of chopped giant reed comparing the common
storage in heap with innovative solutions such as the use
of plastic containers (bins), supplied or not with forced air
conditioning and assessing how the different systems affect
the quality characteristics of the final product.
The remarkable difference among the conditioned bin and
the control bin or the open heap was the behavior of temperatures
in the first 10 days, when the moisture inside the
ventilated bins has fallen about 50 percentage points, while
in the other two the decrease observed did not exceed 20%.
These preliminary results highlights that the use the Arundo
biomass harvested at different growing stages is feasible and
it is possible to modulate the storage system in function of
the final use of the feedstock: conditioned bin for the obtaining
solid biofuel for combustion (also starting from fresh matter)
or outdoor pile for the production of bioethanol.
