Novo compósito: aproveitamento de resíduos de poliestireno (isopor) e de madeira (serragem) na sua produção

Abstract

This study investigated the production of composite from expanded polystyrene (Styrofoam) waste and sawdust in the city of Parintins, Amazonas. The research was experimental, with waste collection, mixture preparation and pressing to form the composites. Three treatments were performed (T1, T2 and T3), using different proportions and combination methods between the materials. T1 showed low resistance and was discarded from the final tests. Treatments T2 and T3 demonstrated better performance in tests of stiffness, flexibility, sanding, nail/screw fixation and water absorption. The results show that the combination of Styrofoam dissolved in thinner with sawdust can generate a resistant material, with good workability and potential for use in civil construction and furniture. The study contributes to the valorization of solid waste and reinforces the importance of sustainability, promoting innovative and affordable solutions for the reuse of urban waste.
