Estudo de caso para o reaproveitamento de pó de MDF na fabricação de briquete

Abstract

The furniture sector is a major consumer of raw materials and so, until the product is finalized, generates large amounts of waste. Currently this branch uses in its manufacturing process, almost entirely reconstituted wood plates, as the MDP (Medium Density Particleboard) and MDF (Medium Density Fiberboard), where the remains of his process, we have accumulated in massive amounts, entering in conflict with environmental issues. However, these companies do not always give an environmentally friendly end to the waste left over from the production process. In this sense, this paper proposed the reuse of waste MDF powder (Medium Density Fiberboard), turning the waste into a new product, adding value to it, collaborating with a solution for improving the environmental quality of the company, bringing back to the production cycle the waste. For it was manufactured an array of compression using tubes, plates and steel angles SAE 1020, in cutting processes with saw, turning and welding MIG / MAG, thinking in the production of briquettes in the cylindrical hollow for purposes of testing with hydraulic press, and also a mixture that used as a binder PVA adhesive dissolved in water so cold pressing, with low cost of final production. The work resulted in MDF powder briquettes with good resistance to compression, hardness and finish, allowing paint and cuts. New possibilities for use, blends and modeling MDF powder emerged, supporting the possibility of reuse of this material.
