Cashew nut shell residue (CNSR) obtained after extraction of the liquid was combined with mixed species of wood particles at different wood to CNSR proportions (100/0, 75/25 and 50/50) (to produce one-layer particleboard. The strength properties, dimensional stability, and flammability of the boards were determined to evaluate the technical feasibility of producing wood-CNSR particleboards with acceptable properties. Results indicate that the type of adhesives and wood/CNSR ratios had a significant effect on the boards’ strength properties and dimensional stability. Isocyanate resin-bonded boards exhibited the highest modulus of rupture and modulus of elasticity but the urea formaldehyde resin-bonded boards had the highest internal bond and face screw holding strength. Most of the boards met the minimum standard for internal bond strength of base particleboard. The rest of the properties failed. Replacing wood with CNSR adversely affected the strength as well as the dimensional stability of the boards. In terms of flammability, however, the ember of boards with CNSR extinguished at a shorter time than the pure wood boards, thus causing a smaller area of damage on the board.
It is estimated that 0.75 Metric Tons (MT) of cashew shell is generated for every MT of cashew nut produced in the Philippines (Fidel et al. 1998). Based on this estimate, more than 200,000 MT of shells have been generated locally since 1994. From the shells, cashew nut shell liquid (CNSL) is extracted for the manufacture of friction dust for clutch lining and brake lining of vehicles . . . . . . read more
