On the Use of Residues from the Sustainable Extraction of Heart of Palm in Agglomerated Panels

Residues obtained from the sustainable harvest of heart of palm from pejibaye (Bactris gasipaes) palms can be managed to produce long and chopped fibers. These fibrous residues can be used to manufacture agglomerated panels and also serve as reinforcement in polymer–matrix composites. In this work, the characteristics of pejibaye fibrous residues are commented and the flexural mechanical properties of agglomerated panels made with these residues are determined and compared with the properties of conventional wood-based agglomerated panels. Also, panels using both pejibaye residues and residues from coconut plantations were manufactured and their flexural mechanical behavior was determined and compared to panels manufactured using only pejibaye residue. The results obtained show that the flexural mechanical properties of pejibaye agglomerated panels fall within the boundaries established by international standards for interior use (general applications–dry conditions). The hybrid coir/pejibaye panel showed the best set of properties, presenting a performance better than the agglomerated panels manufactured with only one kind of fiber.
