Brazilian Amazonian palm-stem types and uses: a review

“…The traditional knowledge on the uses of palm species contributes to the conservation of palm-trees and to devise sustainable alternative sources of income for local communities (Thoma et al 2016), and provides an invaluable information source for prospection of new materials and biotechnological applications. Among current studies on industrial applications of palm-stem products, coconut palm (Cocos nucifera L.) stems have been used in the production of biocomposites for parcial or total replacement of conventional building materials such as steel, concrete and bricks (González et al 2019), in addition to stems of Astrocaryum aculeatum and Bactris gasipaes (Figure 3n-o), that have potential for the development of new products for the furniture industry (Miranda and Rabelo 2008;Trindade and Máximo 2017). The formulation of public policies is necessary to systematize the knowledge on the use of Brazilian Amazonian palm species and to promote the rational use and appreciation for products generated from the woody or fibrous palm stems, in all cases ensuring the conservation and sustainability of the extraction.…”
