This work aims to evaluate the utilization of solid residues in the preparation of panels for civil construction. Panels were prepared from residues based on multilayer packages and plastics, reinforced with lignocellulosics residues (peanut shells and rice hulls). Several blends were prepared with different ratios of components, resulting in twelve treatments. The following physical and mechanical properties were evaluated: modulus of elasticity, modulus of rupture, perpendicular tension to panel plan, water swelling and absorption. All tests were carried out according to the ASTM D1037 and EN 317 standards concerning particleboard. The results were analyzed considering the ANSI A208.1 standard, which specifies the required properties for particleboards. The treatments using rice hulls as reinforcement load and plastic packaging as matrix presented better performance than the treatment using peanut shells. The panels tested were classified according to ANSI standards as low density panels. The present study shows that this technology is feasible and the results presented lead to a promising use as architectonical element.
