Proposta de cadeia produtiva industrial para um material composto a base de folhas vegetais em Manaus através de levantamentos de custos

Abstract

Today there exists an urge of the industry to create and disseminate environmentally friendly production models. The so-called Green Seal is already a requirement for entry of natural products to various markets, [Salomão, 2010]. With the intention to create a material using in its composition using vegetables leaves that weren t not originally used in the composition of any other material, Rocha et al. (2007) developed inside INPA a plate composed of leaves, resin and phenol-formoaldeyde and glass wool, which may have similar applications to other materials such as the MDF, the particleboard and plywood. The production process of the leave s plate has the following steps; obtaining the materials, crushing the leaves, drying of the leaves, preparing the mixture with the resin and leaves, hot pressing and finishing and application of preservative compound. Inputs were estimated such as the equipment required, the space (through the preparation of a layout drawing) energy consumption and costs for energy, labor and materials for implementation in industrial scale producing plates with monthly production of 800 units, with dimensions of 1.2 m x 1m x 20mm. It was observed that the composition of cost is made up of several factors and among them there is a large share of indirect costs which in turn have great influence on the unit cost of each plate. The application of direct costing provides a total direct cost of R$ 52,044.03 to manufacture 800 units of plate means about R$ 65.00 per plate and the fixed costs accounted for R $ 36.20 by plate hence R$101.20 total. Discussing investment necesssary needed to build a leave s plate factory estimated at R $ 943,000 and considering an interest rate of 6% per year, the cost per plate rises to R $ 121.10 before an expected return in five years with presentation of cost about R $ 100.9 per m² made necessary by a discussion of how it should be the implementation of the project and how the costs should be organized, it was observed that a model applied in the manner of an association would make the cost competitive with other materials market in Manaus.
