Aproveitamento de resíduos de painéis de madeira gerados pela indústria moveleira na produ??o de pequenos objetos

摘要

Wood residue panels have been used in substitution of solid wood. As a consequence, the volume of residues has been increasing day-by-day. The furniture industries are the major generators of these residues. Their use as raw material for the production of handmade small objects emerges as an alternative to use the economic potential of this type of residue. The objective of this work was to produce small wood objects using boards and mixed board residues to compare their quality. At first, three workers were selected and supplied with MDF, OSB and plywood boards, as well as graphic projects of 10 small objects. Each worker produced 9 samples of each object. At a second turn, one worker was selected to produce the same 10 objects with three samples, mixing residues from three furniture industries of Ubá, MG. The quality attributes of the objects were evaluated and compared. It was concluded that all the wood boards used are adequate to produce the 10 objects but some boards are better, depending on the attribute evaluated. The objects manufactured with mixed woodboard residues presented similar finishing attributes and no significant differences from the objects produced with wood boards in the following attributes: functionality, weight, proportion and symmetry. Mixing residues of different boards affected the evaluation of the attributes: finishing, beauty and color. An object made from residues of the same board can be more attractive. It is technically feasible to produce small objects using residues of wood panels generated by the furniture industry.
