Obten o de um compósito a partir da biomassa residual e industrial utilizando um reator de contracorrente

The major preoccupation and challenge for researchers is finding sustainable alternatives for the reuse of biomass. In view of this, the goal of this research was to produce a new compact material with minimum defects in its anatomic structure and excellent particle-resin interaction. The material obtained is a type of MDF panel composite made from industrial solid vegetable biomass. The MDF panel was produced using a vegetable biomass blend of Eucalyptus wood (Eucalyptus sp.), asparagus (Asparagus officinalis), sugar-cane (Saccharum officinarum), and synthetic resin from urea-formaldehyde (UF). Physical-mechanical properties of the MDF, including modulus of rupture, strength, modulus of elasticity, density, thermal conductivity and perpendicular traction, were evaluated following EN and ASTM norms. The results obtained were consistent with and, in some cases, superior to those found in the literature. Thus, this research demonstrated the potential sustainable reuse of vegetal biomass to produce useful panels.
