Abstract

The study investigated the use of tobacco (Nicotiana tabacum L) stalk particles as additive in urea formaldehyde glue formulation used to bond plywood. The effect of increasing amount of tobacco particles on shear strength, wood failure, formaldehyde emission and termite resistance of plywood was studied. Addition of tobacco particles from 4 to 8% tobacco particle by mass mixed well and had no significant effect on shear strength and wood failure of plywood using Paraseriant falcaria (L) Nielsen veneers. Formaldehyde emission from specimen containing 4-12% tobacco stalk particles was reduced by 18 to 32% compared to untreated controls. The reduction could be due to the presence of nicotine in tobacco stalk particles that captured residual formaldehyde from the boards. Glueline treatment using tobacco particles at all levels used in this study showed no or limited protection against the subterranean termite Microcerotermes losbanosensis Oshima after 16 week of choice feeding bioassay. Although further research is needed,tobacco particles showed good potential as additive in plywood manufacture.
