Abstract

The objective of this study was to assess the energy value of waste timber in the form of sawdust. Two types of wood: Araucaria (Araucaria angustifolia) and Pinus were evaluated with no defined species (Pinus sp). The sawdust was collected from a timber that receives wood from reforestation of these species in Southwestern Paraná, Brazil. The material collected was evaluated with a calorimeter bomb to determine the gross and net calorific value. The main results obtained led to the conclusion that the sawdust of A. angustifolia showed gross calorific value of 17.32 MJ.kg-1 and net of 17.00 MJ.Kg-1, respectively, and Pinus sp. gross calorific value of 17.23 and net of 16.91 MJ.Kg-1, respectively.

Key words: Wood energy, conifer of reforestation, gross calorific value.
