Influence of Non-Lignocellulosic Elements on the Combustion of Treated Wood and Wooden Panel

Brazil stands out internationally in the production and commercialization of wood products. Although external internal demand for these products is met by Brazilian forestry sector, challenges related to management lignocellulosic waste are evident, as country has structural difficulties sector solid management. Therefore, objective was comparatively analyze performance most abundant materials market, regarding energy recovery at end their life cycles. Pine treated with chromed copper arsenate (CCA), untreated pine wood, eucalypt CCA, uncoated medium density fiberboard panel (MDF), MDF melamine coating were sampled. The characterization included thermogravimetric analysis (TGA), scanning electron microscopy (SEM) energy-dispersive x-ray spectroscopy (EDXA), elementary (EA). presence CCA salts reduced potential biomass, altering burning behavior significantly increasing amount generated ashes. They also caused an increase concentrations (Cu), chromium (Cr), arsenic (As), cadmium (Cd) ashes well lead (Pb)
