Resumo: This study aimed to evaluate the volumetric efficiency and energy produced by three different hybrid clones of Eucalyptus sp: C39 Hybrid E. urophylla (natural crossing); C41 Hybrid E. urophylla (natural crossing) and C11 Hybrid E. brassiana (natural crossing). The survey was conducted in the industries Alliance Araripe Plaster and Plaster Saint Gerard, both in the city of Trindade – PE. The wood came from an experiment in the Experimental Station Araripina which belongs to the Agronomic Institute of Pernambuco (IPA). To quantify the amount of wood it was used the Smalian method. The basic wood density and calorific value were determined in accordance with their respective Brazilian Association of Technical Standards. The firewood consumption was obtained through the monitoring the calcination of gypsum in the factories. The statistical analysis was a complete randomized design. The volumetric productivity of these 7.5 year old clones were, respectively, 158.46, 132.20 and 164.89 m³/ha. The performances during the gypsum calcinationwere 0.28, 0.24 and 0, 24 wood stereos, in form of lap, per ton of gypsum produced. Whem chips were used, the results were 0.20, 0.19 and 0.18 wood stereo per ton.. This results were better than the best result obtained using the wood of native vegetation, 0.30 wood stereos per tonne. According to the values found, it can be stated that the use of wood coming from Eucalyptus plantations in the calcination of gypsum increases the productivity and reduces the area under the intervention required to meet the demand for wood industries in the calcination of gypsum.
