Abstract

The preservation of the environment bacame a fundamental practice nowadays all over the planet. Giving continuity to this ideology we researched an alternative material that uses quickly renewable natural resources for the production of agglomerate sheeting.

In a strategic analysis of the possible materials that could be used for the production of agglomerate, we decided for the soy bean husks, for being a material of low cost, abundant and composed basically of fiber and cellulose. It confers a low density to the material and permits the agglomerate sheeting fabrication with varied densities. To obtain the agglomerate sheeting we took the following steps:

- We used different soybean particle sizes besides the raw husk size;

- We added tannin-formaldehyde glue to connect and waterproof the particles;

- We carried out a compression and polymerization where we obtained quality sheeting, these being submitted to evaluation tests where we confirmed the applicability and efficiency of the soybean husk for agglomerate sheeting manufacturing.

In the whole world, the research for new aggregate development has turned principally to synthetic materials or to the massive exploitation of non-renewable natural resources, while the use of the materials like soya husk, abundant and appropriate, can have a great tendency to minimize pollution, deforestation and final price products.

This new technology turns the implantation of agglomerate producing industries viable, because the soya husk is derived from an amply implanted culture, which hold the concept of Zero Emission or whole usage of the prime material to the current application with low cost and high profitability.
