Abstract:
Pruning residues can be recovered and valorized as biomass for thermal power plants, partially recovering the costs of processing or even generating profits. Although the commercial machines available are different, most of them produce a low-quality chopped material that is not appreciated by the biofuel market compared to a high quality standard wood chip. To provide a further tool, a new prototype has been developed for the collection of pruning residues, with an innovative cutting system capable of producing a calibrated and dimensionally appreciable product. This study shows the preliminary results obtained during two harvesting tests conducted in vineyards in northern Italy.The new cutting device has proved effective with a homogeneous and calibrated chip size between 35 and 40 mm. Furthermore, the results show a maximum length of the chips greater than 80 mm, with a coarse fraction almost absent (0.18%). Further tests will be carried out to evaluate technical solutions in order to improve the particle size distribution, with particular reference to the fine fraction.
