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.
