The use of biomass for energy purposes has been highlighted in as a way to reduce dependence on non-renewable energy sources. Macaw palm, Acrocomia aculeata (Jacq.) Lodd. ex Martius, is an arborescent palm and has a high energy potential from the fruit processing. The aim of this study was to characterize the macaw palm residues after the fruit processing to evaluate its use "in natura" and as charcoal. The endocarp showed higher fixed carbon content, heating value and bulk density compared with other residues and lower ashes content. The heating value of endocarp charcoal was the highest, whereas the volatile matter levels of epicarp charcoal showed higher results. All evaluated residues from the macaw palm fruit processing have potential in power generation, especially the endocarp and the epicarp. The endocarp charcoal has suitable characteristics as source of energy and as a reductant.
