Boron treatment of hardwood lumber: a preliminary cost analysis

Boron was examined as an alternative to lindane for treatment of hardwood lumber. Costs were calculated for systems representative of current practice and for systems most likely for boron usage. The application methods for current lindane-based chemicals and those required for boron differ, as do the end results. Boron treatment provides more thorough wood penetration, which results in better long-term protection of manufactured products. A comparison of costs showed boron was more expensive per unit treated than current systems with lindane, but annual costs could be reduced by selective application of boron with new bulk dip equipment.
