The present work shows the principal storage methods tested by the CRA-ING research unit on SRF comminuted poplar and the preliminary results of a new test made on wood chips coming from different tree portions of traditional poplar plantations. The storage trials were performed outdoor creating woodchips piles of similar dimension. These were exposed to different storage conditions affecting the microbial degradations phenomena and the chemical reactions occurred. The storage dynamics inside the heaps of SRF chips were evaluated by testing different air circulation rate (ventilated vs compacted piles), different size of the chips (piles built with small chips vs large chips), and the influence on pile coverage (covered vs uncovered piles). In all case, the effects of storage on fuel quality were evaluated with respect to moisture content, gross and net calorific value, chemical composition, dry matter losses, and ash content.
