Abstract:
The activity was aimed to evaluate and compare the physical, chemical and energy characteristics of wood chips from four species particularly present among urban trees and potentially exploitable to produce pellets: Platanus x acerifolia, Quercus ilex, Pinus pinea and Eucaliptus camaldulensis. The biomass was characterized with respect to moisture content, ash content, heating value, bulk density, heavy metals, and nitrogen concentration. The lower calorific values of the species varied between 15.11 MJ kg-1 (holm oak) and 18.37 MJ kg-1 (stone pine). The ash content was less than 1% in eucalyptus and pine, less than 1.5% in holm oak, and greater than 2% for plane tree. Chemical analysis displayed for nitrogen content values lower than 1% only in pine, while for cadmium values lower than 0.5 mg/kg was seen only in plane tree. In all other cases examined, the threshold values were respected by all species.
