Resistance of Untreated and Torrefied Medium-Density Fiberboard (MDF) Residues to Xylophage Fungi

The manufacture of wood panels generates a large amount waste. This material can be an option for renewable energy generation. However, long-term storage, exposure to moisture and contact these with the soil facilitate colonization by xylophagous organisms. Torrefaction, heat treatment between 200 300 °C in oxygen-free atmosphere, is process that decreases hygroscopicity while increasing carbon content, efficiency resistance fungal attack. work aimed evaluate MDF panel residues. were produced using eucalyptus bonded thermosetting synthetic resin, under high temperature pressure, torrefied at 20, 30 40 min exposed fungi white rot, Irpex lacteus (Fr.) Fr. (1828) Trametes versicolor, brown Postia placenta. After 12-week evaluation period exposure, mass loss samples attacked T. versicolor P. placenta was similar treatments, except untreated, which had greater losses from fungus lacteus. torrefaction increased deterioration fungi, inverse correlation attack
