Abstract:
In Italy the production of short rotation forestry (SRF) poplar has started to play a significant role as
energy purpose biomas5 and as an alternative plantation for farmers. The climatic conditions of some areas of
the Mediterranean basin are particularly suitable to the SRF poplar for energy production. Local weather
conditions could also affect the storage of the harvested biomass differently. Power plants need biornass during
the whole year, while SRF in Italy is normally harvested between December and March . Long period storage is
anyway necessary, at least to have the water content reduced to an acceptable value for combustion. Today the
transport cost control pushes towards the production of chips : a test to evaluate the energy-wise behaviour of
different chips storage systerns was carried out in Northern Italy. Three piles of poplar chips were bui lt in
February 2007, with biomass harvested and chipped using a Claas Jaguar 850, mounting a specific head. The
piles rep resented four possible different stocking methods: the first was un ventilated pile, the second pile was
fo rmed with simply cumulated material, the third was covered with a special non woven fabrlc, the last one was
compacted by a tractor to limit oxygen diffusion into the pile. During the storage period, weather data and
temperature inside the pi les were monitored. In 2007 october the piles were opened to col lect chips samples and
to study microbial growth zones. Moisture content, ash content, elementary analyses and heating value were
measured. The best method is therefore, energy-wise, the non woven fabric covered pi le: of course, the cost of
the fabric (anyway re-usable) should be taken in account. The compacted pile showed a good result compared to
the uncovered one.
