Resumo(s)
Eucalyptus globulus Labill. is managed in commercial plantations for the pulp and paper industry as a
coppice system. For stand reforestation the stumps are uprooted and at present used as biofuel. In this
study, the biomass of stumps collected in six eucalypt stands in Portugal was evaluated in terms of
physical, chemical and fuel properties. Stumps had basic density between 0.55 g cm−3 and 0.71 g cm−3,
and the chemical composition showed 15.1% total extractives (mainly ethanol soluble extractives, 10.5%),
24.8% lignin and 67.0% holocellulose. In terms of thermal properties the stumps presented 18.9 MJ kg−1
for higher heating value (HHV) and 0.6%, 81.1% and 18.3% respectively for ash, volatile matter and fixed
carbon. The elemental composition (C = 51.0%; H = 5.8%; O = 45.3%; Cl = 0.04%) has adequate values for use
as woodfuel.
