|Abstract in Italian:|
È stata valutata l’influenza dello stoccaggio in cumuli su cippato ottenuto da due diverse parti di pioppo per destinazione energetica: fusti e chiome. Mentre i fusti trovano impiego nell’industria del legno, le chiome rappresentano un materiale di scarto che potrebbe trovare un’opportuna valorizzazione energetica a beneficio della redditività della coltura.
|Abstract in English:|
Italian poplar plantations cover about the 1.3 % of the
national forest surface. Poplar cultivation for wood/timber
production has a productive cycle of about 10-15 years.
Generally, wood industry separates the stem from the crown
in order to use the first part of the tree to produce material
of different kind such as veneer, pallets, panels, etc. On the
other hand, crowns usually represent waste material to be
disposed of, causing economic and time losses. In fact, the
revenues related to this material do not always overcome the
costs for handling, management and transformation.
The aim of this work was to evaluate the storage effects on
wood chips produced from two different parts of poplar trees
(Populus x canadensis M.): stems and crowns. The separation
has allowed monitoring the storage behavior of the two
chip kinds in an independent way, evaluating which type of
product would respond better to the storage effects.
Upon felling, plants were divided in stems and crowns,
chipped, and stored in open air piles keeping separated
the material of different origin. The effect of storage on fuel
quality was evaluated through chemical and physical analysis
according to standards UNI EN.
Results showed that chips from crown material had better
storage properties and exhibited lower decay than chips
from stem wood.
