Viabilidade técnica e econômica da madeira plástica (wood plastic) produzida com plástico reciclável e endocarpo de tucumã (Astrocaryum sp.)

Abstract

The economical and productive viability of wood plastic in Manaus was developed in this work. Initially, the marketing chain of the tucumã was characterized in order to establish the distribution of the vendors and points of supply of the fruit in the zones of the city. In a second stage, an investigation was carried out into the production of recyclable plastic waste, according to the city zones, aiming to increase the amount of information. In addition, strategies were proposed based on the economic viability study for the implementation of recycling programs according to the best regions of the city. In the third step, a review covering several aspects of the production chain, such as historical evolution, composition, production and application of wood plastic in world terms was presented. In a fourth step, the possibility of producing wood plastic from the mixture of low-density polyethylene (LDPE) and the endocarp of tucumã is reported. Due to the success of the production of wood plastic with LDPE, a composite of wood plastic obtained from polypropylene (PP) and the endocarp of tucumã was obtained. In this work it is possible to observe that with the quantities of woody endocarp and PP discarded in the environment, it would be possible to inject in the local economy around R$ 3.58 million per year to be applied in a range of product possibilities, such as floor plaques and coatings, support of cell phones, picture frames, clipboards, etc. In contrast, R$ 46 million in recyclable plastics are disposed annually in the sanitary landfill of the AM-10 that could be reused commercially.
