Nowadays, from a quantitative point of view, the woody biomass represents the most important source for energy production. For these reasons, “CRA-ING” is carrying different kinds of storage experiments on chipped poplar coming from Short Rotation Forest plantations (SRF). The experimentation aims to compare the physical characteristics of six chip piles stored using two different methods. In the first one, chips have been covered by a geotextile sheet; in the second the woody material remained uncovered. Furthermore, the CRA-ING has analyzed six piles having chips of difference size. Three of them were obtained using the self propelled forage harvester; the others three obtained using the same machine equipped with experimental rotor developed by our institute. The experimental tests have been carried out with the aim to evaluate the variation of the chips physical parameters occurred during the two different storage method. In addition was aimed to analyze storage efficiency due to chips size. In conclusion, the final result of the experimentation demonstrated the possibility to improve the quality of the chips increasing their size as well as that it is possible to obtain an efficient and economic storage system through the uncovered pile.
