Açaí (euterpe oleracea mart): extrativismo, características, energia e renda em uma comunidade na ilha de Marajó/PA.

Abstract

Objective of this study was to evaluate the characteristics physical, chemical and thermal structures of the vegetative açaí (Euterpe oleracea Mart.) Chipaiá in the community, municipality of Cachoeira do Arari of the State of Pará . The certain parameters were: humidity tenor, density, tenor of volatile materials, tenor of ashes, tenor of fixed carbon, to can calorific superior and inferior and the energy potential of each vegetative structure of the açaizeiro, after the extraction process of this fruit. The results indicate that all structures of Acai may be used for energy purposes, and the stone was the most promising, because in addition to improved physical, chemical and thermal, in comparison to the others analyzed (cluster, leaf and stipe ), has better equipment for handling and greater availability, and different bunch of leaves, which need have a dense, as well as the leaves and stems that are not easily accessible by the community.
