14. Thermoplastic polyolefins as formaldehyde free binders in highly filled lignocellulosic panel boards: using glycerine as a processing aid in kenaf fiber polypropylene boards
A new technique was developed to make highly loaded (up to 95%) formaldehyde free natural fiber boards. The purpose of the paper is to report a broad study on 85% kenaf boards using linear thermoplastic polymers as the binder in preparing the boards to determine if these materials have potential in commercial applications by comparing them to other commercia

17. Qualidade da Madeira Serrada e dos Painéis Colados Lateralmente Obtidos de um Plantio de Eucalyptus saligna Smith Visando o Segmento Moveleiro / Quality of the Sawnwood and Glued Panels Obtained of a Eucalyptus saligna Smith Plantation for Furniture Industry
In this research were studied thirty trees of Eucalyptus saligna Smith wood, sampled in a twenty year-old plantation located in Seropédica/RJ. Each tree supplied a log with 2.30 meters in length for the study of the sawn process and panels production (PCLs). The processing of the logs was made in the LPZ Madeiras and Artefatos Ltda sawmill - Piraí/RJ, bein

19. Small objects manufactured with residues of wood panel generated by the furniture industry. / Pequenos objetos de resÃduos de painÃis de madeira gerados pela indÃstria moveleira
In the last years, the use of wood boards by the furniture industry has been increasing in Latin America. Therefore, the residues generated are discarded in the environment or sent to steam production in boilers, causing ecological impacts. Small wood board objects are a lucrative alternative to take advantage of this kind of residue. The aim of this work wa

24. Otimização da secagem da madeira de Eucalyptus grandis (Hill ex Maiden). / Optimizing the drying proccess of eucalyptus grandis [hill ex maiden] lumber.
The use of Eucalyptus lumber by the wood manufacturing industry is growing, mainly to added value products as furniture and flooring. However, this row material requires a slow drying, which means an increase of production cost, proportional to residence time of lumber in the kiln. To combine air and kiln drying has been suggested as an alternative to reduce
