Industrial activity is growing at an increasingly rapid accelerated bringing impacts not very consistent with the preservation of the environment, since it uses its resources to meet its countless demands, making the sources begin to become increasingly scarce. Therefore, this paper proposes the use of waste a furniture industry for the production of panels for the interior decoration. Were used to manufacture them, two different types of materials, where such, the Kraft paper is more efficient for the underpinnings of these panels. Regarding the type of glue used, the contact yielded better results. The initial conditions for the development of such a proposal were based on existing laws for solid waste as well as proposals for environmental agencies

This study aimed to evaluate the physico-mechanical performance of three PVA adhesive formulations according to the Brazilian standards for plywood testing and to evaluate the results with those presented in the technical literature and specified in normative documents. The study presents the production process of the panels, the obtaining of samples and, finally, the implementation of physico-mechanical characterization tests based on plywood Brazilian standards. For the panels production it was used a gramature of 120 g / m² and applied a pressure of 15 bars and two temperature combinations and pressing time for each adhesive. The commercial adhesives used were PVA 1810, PVA 1060 and Vinyltec 239. The physical tests conducted were thickness swelling, density, moisture content and water absorption. The mechanical tests were static flexion, for the determination of elasticity modulus (MOE) and rupture modulus (MOR), and shear in the glue line. Among the three formulations studied none showed good performance in the presence of water. However, other trials in the adhesive showed better results and closer to the commercially equivalent used, in the case the urea-formaldehyde, was the PVA 1810, that can be applied in non-structural uses and in environments without the presence of moisture
