Bioprodutos produzidos com resíduos do manejo florestal sustentável da Amazônia

Abstract

The species Tachigali paraensis is promising for Forest Management Plans in Pará but still lacks scientific studies. In panel production, petroleum-based adhesives pose risks and depend on non-renewable sources. Research is advancing in sustainable alternatives, such as cardanol- based adhesives, aligning with sustainable innovation. This study investigates the use of T. paraensis residues to produce bioproducts, such as Drywall and Medium Density Particleboard (MDP), using natural adhesives like cardanol, derived from cashew nut shell liquid. The analyzed properties for both biocomposites included physical, mechanical, acoustic, and thermal characteristics. For drywall, the results showed that plant particles reduced the density of the composites, making them lighter and improving thermal resistance, demonstrating potential as a thermal insulator for construction applications. Despite a slight reduction in flexural strength with increasing particle concentration, all composites met the requirements of the EN 13279-2 standard. The results for MDP indicated that the produced panels exhibited adequate physical and mechanical properties, meeting technical requirements established by specific standards such as ASTM D1037 and EN 312. The use of T. paraensis residues and natural adhesives, such as cardanol, proved viable for the production of sustainable biocomposites. These materials comply with technical standards and offer benefits for the construction industry, promoting innovation and efficiency.
